2017/08/13 - Things still the same
- Unfortunately there is nothing going on, but I hope to change this soon.
2017/07/13 - Busy
- Well, what can I say? It's 23pm and I'm still working! Unfortunately no much time left for hobbies.
2017/06/13 - School Project
- I'm not having too much time lately because school exams and work is taking a lot of my time.
- But I'd like to show a school programming project in C that I wrote 3 hours ago.
- It's a raycasting running in Console Mode. Below you will see two versions, one that I wrote using Evaldraw and the second one in C with Windows API (School uses this system).
- I'll add a maze generator which I already wrote in VBA.
- By the way I'll share the code soon I finish everything.
Evaldraw and Console.
2017/05/13 - Well...
- Last post I said that I was looking for a small demo to be release in a few days, which was true until I had school exams and then a cold.
- Those two things together took out my mood for anything. So I'll try to accomplish now.
2017/04/13 - Busy, but...
- I've been busy, but I'll try to come with a small demo for the next days.
2017/03/13 - Monthly update
- Still working on the projects mentioned below.
- I've found a way to draw pixels way faster in VBA/Excel using DIBSection*.
- *DIB: Device-Independent Bitmap.
2017/02/13 - Projects
- A small update about my projects which I am working right now:
- - My own editor in D.
- - A small game in HTML5.
- - Two demos/games for Excel.
- - A game for an old console (Neo-Geo).
- PS: Those are in order of last update.
2017/01/13 - Writing my own text editor in D language
- This is the second time that I write a text editor, the first one was using GtkD. But there were a few problems:
- - Memory leak from GtkD library. (Problem which I solved by myself).
- - It was slow to initialize on the first time. (Most because loading the library).
- - The size, again because the library.
- So, I wasn't too happy with it and now I decided to write a new one, but in text mode, in fact running directly from the terminal.
- My target is: a simple and intuitive editor, with some functions and shortcuts the way I'd like to.
- Why not just use an editor that already exists?
- Because I was getting frustrated with editors and key-bindings since I use Dvorak layout, and every re-mapping stops working another thing.
2016/12/21 - Last post of the year
- So it's almost the end of year, and finally a must deserved school break. Right now I'm looking on what I'll spend my time. Remembering that I still have to go work though.
- I don't know if I'll work on a old project or start a new one. There are a lot of things that I'd like to do. But again I need to evaluate the best option.
- Merry xmas and happy new year.
2016/11/21 - The old monthly update
- Well, the current status isn't much different from last month, working everyday plus school (And now with exams) leaves me almost with no time left for other things which is pretty much lame.
- I'm trying some demos and testing new things which I hope to get more seriously soon, because I miss that so much.
2016/10/21 - Still pretty much the same
- Lack of time is my big issue so far. I just have half saturday and sunday to rest... but wait guess what? There is always some homework to do.
- All projects are on hold which is pretty sad.
2016/09/22 - Like a Zombie
- Well a 9-5 job plus school is not so cool! I'm living pretty much like a zombie!
2016/08/22 - VBA
- Well, time is running short lately, I started college which is taking 6 days of the week (Monday to Saturday) and besides that I have a 9-5pm job, so It's very hard to find time to sit and work on my projects for now.
- In the programming course at college I have 2 programming lectures, one using C language and the other with VBA + Excel, both are very basic right now, at least for me since I'm already a programmer, so instead of writing macros to just change the values of the cells I decided to use that time and play around with some more challenge stuffs.
- So I wrote a Pong and a 3D Wireframe Cube with VBA + Excel and below you can download both demos.
- To run these demos you will need to Enable Macros support or nothing will happen. In the case of the 3D cube, there are 2 versions, the only difference is that in one I'm using Application.ScreenUpdate to avoid flickering, but since it doesn't works on every Excel I wrote another version without it.
Choose one and click to download
2016/07/22 - Monthly update
- It has passed a month since my last post, so it's time for an update.
- So, things have changed a lot over the months: new Job, university entrance exams and others projects. Unfortunately I haven't had time to finish DMC, which is by the way pretty much complete since March. I just need to wake up with a good mood to publish it.
2016/06/22 - New layout and more
- So, I was in the mood and I just decided it was time to update the layout of the site.
- And now about my new game, it has been a long time since I said that I would upload it on my site, but unfortunately I've been busy with work and studies. Like I said previously it is almost done, it just need some tuning here and there.
2016/05/26 - How time flies
- It has passed more than a month since my last post and I'm still here very busy with some side programming projects and other studies. I'll try my best to find some free time to finally finish my latest game DMC and upload it.
2016/04/23 - No free time yet
- Unfortunately I wasn't able to find a free time to code my game this week, and like I said other day, I'm still facing some personal problems. So for now I put as deadline the end of month to finish my game and I really hope to achieve that.
2016/04/15 - News about the Firefox bug
- A couple of months ago, I had written about a bug that I encountered just after update Firefox for Android. The bug was about a problem with the canvas element, where nothing happened when I tried to draw on it.
- Today an user named craigleat answered a topic that I had opened on Mozilla Support about the issue and with a way to fix that problem.
- If you're facing this problem it can be fixed turning the variable gfx.canvas.azure.accelerated to false inside about:config (You need to type 'about:config' in the address bar then press enter). And that is it and of course I updated the bugzilla too.
- PS: Like I said previously, I'm still unable to code anything. I hope to come back on next week.
2016/04/06 - Info
- Unfortunately since my last post I've been facing some personal problems which put my development on hold. I hope to be back soon.
2016/03/30 - More about DMC
- The last days more than coding I've been trying some optmizations for my new game DMC. Until now just one background from a level of this game would consume 492KB, then after some tweaks and changing pixels here and there I was able to decrease the size to 162KB. So less time to wait from the game to start.
- By the way I am using a new tool that I found called ImageMagick. It's a command line tool which I prefer and very easy to handle many images.
- I'm using some assets like menu and the code part from Super Canvas Kart on it too since the settings are almost the same. Overall the game is almost complete, but I am always trying something new and then I keep holding it. Anyway I want to release it on next week.
2016/03/25 - Optimizing Images
- Over the course of the last months I've been trying new ways to optimize the size of the images of my games without losing too much quality. This is good for both sides, the server and users which will get to the game faster.
- Here are some numbers of what I got after playing with GIMP and PNGOUT:
- New Canvas Kart: 164KB to 33KB
- Prince of Canvas: 391KB to 207KB
- PaCanvas: 42KB to 15KB
- Solitaire: 60KB to 24KB
- 9Ball: 132KB to 80KB
- Another visit on Solitaire: I received a new bug report from GJ Brown about a strange behaviour in solitarie, but he unfortunately couldn't provide too much information this time, but a screenshot. The problem was much like the first bug he reported but occurring on the Piles. I just applied the same fix and looking more closely the source I found another possible bug and of course it was fixed too.
2016/03/23 - After release
- My humble site got a great bump of visitors since the release of New Canvas Kart.
- In most cases I've saw positive comments. But of course there are some talks about how simple the game is, and they are right the game or let's say demo is very simple indeed.
- Mobile and Chrome
- Since the beginning of the year I've being measuring the user access of my games, and most of them are from those on Mobile and using Chrome. Then after that I decided to aim those kind of users.
- But there is a catch, because currently rendering things on Canvas runs slow on Chrome for Android, in fact very slow. You can try by yourself using a Canvas with size of 480x360 and drawing 5 or 6 images on it, and of course doing some rotation, scaling and so on.
- Trying to make it faster
- I was decided to make this new demo to run acceptable for Mobile users, and for this I tried a lot of things. For those who didn't notice, during the gameplay I just update half of the screen, exactly where you see the track.
UI things like the counters for lap and position are updated on their own regions, just replacing the numbers. The entire screen is updated just when user interact with menu or pop-ups.
- For you see how things are hard, the first version from 2013 had a mini map showing the player and CPU positions and guess what? In this version it had to be dropped.
- Until now I just talked about graphics, and about the controls? You can see my dilemma here.
- Like I said most of the comments were favorable, but I thought that I should talk more about it and explain why this game or by the way demo looks the way it is.
2016/03/22 - Bug where?
- Just after the release of the New Canvas Kart, I was told that the game wasn't working on some iOS devices. Well the main problem when something like this happens is when you don't have a device to test, and that was exactly my case.
- Thanks to the Browserstack I was able in less than 30 minutes, which was the period of the free trial, to solve the issue. For some reason when using some settings of google's compiler it caused that device to read some garbage on certain variables.
- By the way I take the chance and used my last free trial minutes on Browserstack to test the demo on IE 11, and it worked.
2016/03/21 - New Canvas Kart Released
- From time to time I used to receive e-mails about this game. Most questioning about the lack of features. Well the first version was just a demonstration of Mode 7 on canvas. Back then it used to have a label like WIP - Working In Progress on it. In fact I changed here and there a couple of times, but now I changed a lot.
- It's important to say that while upgrading this old demo, I was working on 3 more projects, being 2 other games yet to be released: DMC and one game from Konami. So this demo is still far from perfect, I spent most of time tweaking for speed, then the A.I. of the opponents isn't a big deal, and there will be glitches and so on.
- Controls on mobile
- This was one of my main concerns. I was trying to figure out a nice way to use the screen to handle the Kart. First I thought about buttons, but it wasn't very nice, it was polluting the screen, then I thought about divide the screen in half, where one side it would be used for direction and the other for accelerate and reverse. The problem here was that in any case I would need to think about right-handed and left-handed players.
- Finally my solution for this was: Touch and hold to accelerate and slide for turning the kart. There is no reverse on Mobile.
- More about mobile
- I tested this demo using Galaxy Tab 3 with Android 4.4.2, using the Native Browser it runs almost full speed with all settings on max. With Chrome I can run reasonable well with screen size on medium and graphics on low.
- One tip: If you think the game is running too slow after the start just access the menu and restart the race, don't use refresh. This may fix the problem, because while you're playing for the first time the game will download the music.
- Well overall counting all the limitations I think it's very presentable demo now.
- New features
- Faster game for Chrome on Android.
- Option for changing graphics settings: quality and screen size.
- Sorting racers according distance before draw.
- CPU and Player dispute laps.
- Grass/sand slow the player.
- Racers can collide against each other.
- Banana Peel causes a vehicle to spin-out.
- Better UI and controls, mainly the "Touch".
- New music from the original game.
2016/03/18 - Almost done
- The new version of Super Canvas Kart is almost ready to be released. I'm polishing it and doing the last adjustments. I'm done with adding things and by the way It will at least 9 new features. And the most important It was optimized for Mobile.
2016/03/15 - Fixing a bug and more
- What is supposed to happen in Solitaire when you try to drag a card from a empty Deck to a Pile?
- Nothing, right? - Well in my game there was a bug and it could duplicate the last card moved. The bug was reported yesterday by GJ Brown and I fixed today.
- Since I was looking the code, I took a chance to change more things to make the game a bit faster, and finally I updated the UI (User Interface).
- More: I am still working on the Super Canvas Kart and DMC. I'm adding new things and trying to speed up those games on Mobile and so on. Unfortunatelly the last days was a bit complicated. But let see if I can release anything until weekend.
2016/03/12 - Prince of Canvas Returns
- Yesterday while I was thinking about a simple and intuitive way of doing the controls for Super Canvas Kart with touch screen, I just realized that my first game Prince Of Canvas and the 2nd most visited game in my site never had a change to be played on Mobile.
- Once upon a time
- Back in 2013 I had seen a demo of Prince of Persia in HTML5 somewhere on the internet. The demo was just a room with the animation of the character going on side to another and that was it. Then I decided to make a better demo, at least showing the first level of the original game. I even wrote a built-in editor to handle where the prince could go, climb and so on.
- At time I didn't bother about Mobile support because I didn't have one.
- The funny thing is that I still remember receiving e-mails asking how to play on Mobile. Well at least now you can.
- Caveat: I need to point out that this new version may present some glitches on graphics. This is because I changed the drawing function to minimize redraw and improve the speed on Mobile. Since this is an old source I didn't want to bother waste too much time one it.
- Here are the new features
- Can be played on Mobile now.
- Added Mouse support for PC.
- Increased the game speed.
- Fullscreen option.
2016/03/08 - Info about 2 games
- Since the weekend I've been alternating the developing between 2 games, Super Canvas Kart and my new game with the codename: DMC. The big issue here is to make both games running fast on Chrome for Android, because with the Native Browser they're already running fine.
- In the case of the Super Canvas Kart it is not only the speed that has been improved. Just to remember the first version was basically a demo showing the Mode 7 like perspective on Canvas, but now I'm writing a better demo which I'll try to release until the next weekend.
- The new features will be
- Faster game for Chrome on Android.
- CPU and Players disputing laps.
- Collision with grass/sand slowing the player.
- Better UI and controls, mainly the "Touch".
- New music from the original game.
2016/03/06 - Revisiting my old games
- I woke up saturday decided to take a look over my old games, I mean over the code and since I was in the mood, I took a great breath and I started to review and improve the code.
- The games were Super Canvas Kart and PaCanvas. Both games runs fine on PC using Chrome or FireFox and relatively fine on Android when using the Native Browser, although with Chrome for the same platform it's indeed slow.
- Super Canvas Kart needs a really deep thought, it's running faster now on my tests, but I'll change other things which will take some time, so I'll work more over the week.
- PaCanvas suffered a bit a revolution, I used to draw PacMan, Ghosts and Food using context functions like: fillRect(), arc(), stroke(), and again while on PC it runs faster even on a modest hardware, for Mobile it's another story.
- I changed all the old drawing routines for new ones and remade some graphics. Here is how it looks now (left) against the old version (right):

2016/03/04 - Another few update
- I'm still testing my new game and tweaking here and there.
- About the new feature that I was thinking to add, well I just dropped. It would be need too much tests which I'm not able to do right now, maybe next time.
2016/02/26 - Few updates
- Today it's almost a week after my last post here, so it's time to review what I've done.
- Despite my low development week, the Map Editor is done like the map for my next game, where now I'm just polishing here and there.
- And talking about that the game, currently it's in test mode and I usually prefer doing this tests in large steps, because things that seemed good yesterday maybe is not so good today.
- Concurrently I am thinking about the ways to make the game challenging. I have many ideas but some need to be in sync with a new feature that I'm trying to implement that I never used on the other games.
2016/02/19 - Map editor
- I said yesterday about the map editor that I've been working on for my new game, and one thing that I like with web development is that I don't need to worry to much about things that I used to. In this case I'm talking about GUI or Graphical User Interface.
- For my map editor I just mixed Canvas and HTML inputs like: Text, Buttons, Scrollbar and so on.
- It's easy to fix or change the positions of the controllers and the most important again, no worries about DLL's, O/S support or whatever. Just like the games you just need to upload and that's it.
2016/02/18 - Reviving an old project
- While I was looking over my old projects, I've saw some unreleased or aborted games, and one of them was one that I used to call DMC, which I mentioned in 2013 (see bellow). The game was 70% done at the time, but the art as the way I was thinking the game was a pain to work. So I just came up with a new idea where I could easily extract and use the art without any change.
- Since the art isn't the problem anymore, It was needed to change the engine, and that what I am doing right now, together with an built-in level editor, which I'll talk more about it later.
2016/02/13 - Bug on Firefox for Android
- Just discovered that none of my demos are working on Firefox for Android anymore!
- Yes I've upgraded Firefox on my Android (4.4.2) just to see that Canvas isn't updating as it should.
- In this demo I am updating a div and canvas with current timestamp, it's a small code and should work fine. The div is updating correctly while the canvas it isn't, in fact I notice that even the refresh (F5) isn't changing the state of the Canvas.
- I posted about this issue in mozilla's bugzilla and support.
2016/02/11 - Little changes on 9Ball
- Drawing the ball numbers using image instead of filltext routine.
- Fixed the control delay.
2016/02/10 - Audio Bug on Chrome (Android)
- I've just discovered that the audio on my latest game Canvas 9Ball wasn't working properly on Chrome for Android. If you see this link you will see this is a known bug (Started in 2013) and with comments even nowdays.
- The bug is not simple as it seems, because I made a lot of tests yersterday on my local server and it was working fine, but when the game is loaded from my hosting service the sound just play once and stops.
- Hosting or Chrome fault: I don't know yet whom to blame, but the sound works fine on PC using Chrome/Firefox and Android with Firefox. But it was occuring with Android/Chrome just "when" the file was being downloaded from my hosting server. While if I set the audio source to another server it works!
- I didn't have too much time to investigate this deeply, but for what I see there are differences from the response headers from the servers.
- Fix: For now I'll set the sound source to the other server. Anyway I'm still making some tests using Ajax to get the sound data and then loading using AudioContext, and from my preliminary tests it works with any server.
2016/02/09 - Canvas 9Ball - WIP
- I changed almost all the text for respectives images. Most because fonts on differents browsers and platforms wasn't helping here. The only place that I still using plain text are for ball numbers, which I'll change later.
- The background image was optmized too, in fact even it's larger than the old version but now It's about 20KB smaller too.
- Finally I added a little music loop.
2016/02/08 - Canvas 9Ball
- Finally a beta version of my latest game which like the name implies it's based on the pool game called: Nine-Ball and It follows some rules of the real game too.
- I didn't have much time to work on this properly today, but anyway, I tried both Chrome/Firefox on PC and Tablet. On PC it runs 60 frames with no drop. On mobile the Firefox seems to run faster than Chrome (Android Kit-Kat 4.4).
- The development is not over yet, I'll try to optmize more and add music, sounds and one feature over the week.
2016/02/07 - Another status
- The game that I've been working isn't done yet, it is very close and I could even put it online like a Beta or something, but I prefer to take one more day and polish it more, besides that tomorrow is some sort of holiday where I live.
- For now I'd say the game is 90% done. Let's see if I can finally deliver this game for tomorrow.
2016/02/05 - Status
- I'm still working on the 2 games that I said previously, but unfortunately I can't finish for today although I hope to upload one of them on the weekend.
- I usually wrote my games on a sort of C-script language with a built-in environment because it's fast to write/test. The script of one game is already done and I've ported about 50% of the code to JS, but one thing that is taking my time right now are the graphics.
- Well no one said this would be easy, especially when developing all alone. :)
2016/02/03 - Tidbit
- Still working on the project that I've said below plus another small game which I pretend to finish until friday (02/05).
- Layout: Yes I am tweaking again on it, and using a Pngout (From Ken Silverman) to reduce the size of images.
2016/01/27 - Another game in Progress
- I'm writing another game which will be based on a level of an old game made by Konami for the SNES.
- Layout: I've changed the font size and style.
2016/01/23 - Solitaire clone
- Recently I read an article on Hacker News about the programmer of the Solitaire game for Windows and after that I decided to write my own version in HTML5, which the result you can check above.
- Finally I'd like to say thanks to Ken Silverman for the tips, especially with the correct way of doing an uniform shuffling.
2016/01/07 - Layout
- Just changing the layout a little bit. Want to see the difference? Compare following this link!
- Added Canvatrix: A demo that I made in couple of hours after looking a similar one somewhere yesterday. First entry of 2016! :)
2015/05/29 - 3D rendering and new layout
- How time flies...
- I'm owe a demo about my 3D rendering system on canvas since two months ago, which was already finished since then, but unfortunately some problems happened and I had others priorities. Anyway like they say: better late than never.
- Canvas Boing Ball: For a small test of my 3D rendering on Canvas I chose to recreate an old classic from Amiga called: Amiga Boing Ball.
- I'll post some benchmarks later running on desktop and mobile.
- Layout: Finally I wasn't very satisfied with the old layout then I changed it again and I hope you like it.
2015/02/13 - Updated the website
- Time to change the layout a bit.
2015/01/?? - Vacations
- I'll use this month for some reflections.
- PS: The 3D demo that I said earlier is completed, but I'll wait next month to upload it.
2014/12/?? - Holidays
- Writing a demo to test the performance of my 3D rendering LIB on canvas across many browsers and systems.
- Took the holidays to change the Operational System.
2014/11/25 - Writing a LIB
- Now that I'm back full time to my games, I decided to write a LIB for handling my new games and of course to be handy and easy to maintain.
- So for now I'm testing my LIB on desktop and mobile (Android and iOS) and on 3 different Browsers. Then on every feature added I check the FPS for bottleneck and performance.
2014/11/11 - Info
- I quit my job again after a year to refactor myself! :)
2014/10/17 - PaCanvas updated 3
- Optimized some draw functions, added lives and remade game's message system.
2014/01/15 - PaCanvas updated 2
- Fixed incorrect screen warning when mobile is in Portrait mode but upside down.
- Improved touch movement.
- Added an increase of game speed while passing through levels.
2014/01/13 - Open thought
- Well as I said previously that I was working on a new project called SU which until now I just made some sketches and the intro, but before continuing on this I'd like to present the new kid on the block, another project called SC.
- SU and SC: First of all, the SC project was started around a year ago, while I was doing my first steps with HTML5, but I cancelled it some days later for some reason which I think was about the Technology.
- Well, on meanwhile I published 5 demos and dropped out others 2. So currently SU is my key project but on the other hand SC in essence seems like a small version of SU, where "small" means faster to accomplish too and better yet is that all the assets of SC will be used in SU.
- So, I thought it would be more smart finish the old SC since it's smaller and simpler than the SU, and that is what I'll do from now.
- TL;DR: SC was a project that I started a year ago and cancelled some days later, but in essence it's a smaller version of SU, then I decided that would be more coherent firstly finish SC and use it's assets to develop SU later.
2014/01/11 - PaCanvas updated
- Levels has time to be completed, user interface improved and new movement system by sliding finger across the screen on mobile device.
- Works on project SU continues, intro animation is around 65% done.
- Finally the new site's layout it's on air like the first beta version of PaCanvas, enjoy! :)
- The research about SU project continues and I'm really getting excited about it
- Started some drawings and sketches about a new project called: SU which I've been thinking to start for a while.
- Reworking on the website layout.
- PaCanvas almost finished (After a lazy development cycle because holidays).
- Started some experiments with PaCanvas (Pac-Man clone).
- Added the Hexagone game and that was the first time testing and programming using a real mobile hardware: Galaxy Tab 3 and iPad Mini (Cortesy of my niece).
- After a new deal I got back to my old job.
- Stopped the DMC project with engine around 70% done, but on the other hand having to rework on the art was both: boring and consuming too much time.
- I resigned from my job to get a free time to myself and study more about development.
- After some requests, I started working on touch feature for Super Canvas Kart, but unfortunatelly without any real hardware to test I had to use emulators and the result wasn't good, I dropped the development, but you can play the alpha version here (again: The touch doesn't works 100%).
- Working on a demo idea based on another Nintendo big franchise project called: DMC.
- Stopped the Kanvasteka development with around 80% completed.
- Added the Super Canvas Kart game demo.
- Added an image of would suppose to be my next game: Kanvasteka.
- Working on 2 clones: Super Mario Kart and Karateka.
- Added the Prince of Canvas game demo.
- I dropped all my previous projects from desktop to focus on internet after being hooked by HTML5.
