Pixilang - programming for fun

[NightRadio]

Hello all!

Lets introduce you my new project - Pixilang v1.0 pixel-oriented programming language. This is a simple programming language for small graphics/sound applications. Great tool for creative people like a designers, painters, demosceners or some other inquisitive persons :) Any pixilang programs keeps in a simple TXT-files, so anybody can edit it in his lovely text-editor. Pixilang interpreter works on different operation systems (Windows, Linux, PalmOS) and distibuted under GNU GPL license. It's fun and beautiful.

Main features:
* easy syntax and small amount of commands;
* universal containers (pixi) using for text/gfx storage;
* pixel graphics describing in a source TXT-files directly (using ASCII symbols);
* transparency (simple and with alpha-channel);
* simple commands for rotation and resize;
* no floating point math operations - only 32bit integers are using;
* playing music in MOD and XM formats (using PsyTexx engine);
* loading GIF (animated) and JPG file formats;
* realtime export to GIF;

Will windoze code work on PalmOs, or are changes necessiray?

Will download tonight and check. Looks pretty cool from what i can tella tm!

[NightRadio]

Code of Pixilang-program can work on any OS without any changes :)

I loaded the 16 bit app on my TX. It crashes everytime I launch.

Tested the windows version. Looks cool. I would like to see it on my TX if it will work.

Thanks.

[NightRadio]

8 bit version is not working too?
Please, mail me nightradio@gmail.com. I want to fix this problem.

[phreakonaleash]

i can't figure out the palmos interperator. all it does is blank the screen approx 1sec and goes to the launcher... How to run the examples?

[phreakonaleash]

OK, /me is confused...
has ANYONE, ANYONE got the app running???

I install it and appearantly te archive is corrupted or in the wrong soemthing or other, because the icon crashes the launcher, Resco Explorer, etc... Bird crashes when i try to break open the form resource

NightRadio, could you perhaps put it in a zip archive in case it is MobileRAR destroying the file? Then mail it to me or upload it on your site?

I really would love to get this working!

ALT: What are the dependancies of the source?

OK, /me is confused...
has ANYONE, ANYONE got the app running???

PhreakOnALeash~ I have not had any success yet either. My TX actually soft resets (not just the launcher). I have tried three versions via email. Haven't heard much in the last couple of days. I do not think my testing has added a lot to help NightRadio.

I also would love to see this work. Looks like fun and relatively simple to program.

Sounds like you might understand the programming side more than me. The different result on your device seems interesting.

Hopfully we'll hear back soon.

unRAR for windoze will open it. MobileRAR crapped all the rars i had so... :rolleyes: i can email you a zip tonight palmuse...

Nightradio: This is a nice little app! Will get some of my own scripts and gifs up here soon possibly...

[alt236]

Hmm... it works fine for me when I unrar it from windows.
I didn't hotsync it though, I copied it from my SD card (it might make a difference?)

It's a tad slow, but fun :)

[palmuse]

unRAR for windoze will open it. MobileRAR crapped all the rars i had so... :rolleyes: i can email you a zip tonight palmuse...

PhreakOnALeash~ I would appreciate that. I have been using ZipGenius to uncompress. Maybe it is corrupting the prc. If you have a working copy, I would like to try it. palmuse_at_comcast_dot_net Thanks! :D

[NightRadio]

Sorry. Next version will be in ZIP :)

[phreakonaleash]

Ok... Here goes:

It worked for approximately three hours after I posted then inexplicably died...

I see the words 'SUNDOG STARTER APP apr3'. The app soft resets about an a half second later...

Could I make a suggestion?
Either use Pruss's Diagnoser (http://www.1src.com/freeware/fileinfo.php?id=1653) or use a method similar to dkirker's earlier debugging fo Universe3 in which a sequence fo numbers are written to the screen with a delay to see what the number is, then we can find where it dies...

I would LOVE to get this consistently working so i can get to work on making some nice gfx fun...

..oh yeah: any chance of adding pdoc/memo support? and after that, reacting to sysAppLaunchCmdOpenDB so that users can set the launchable bit (in Resco Explorer, filez, etc) so that they can be launched and opened from the launcher? please??? :-D

sorry for the flood.

@palmuse: having large mail problems atm... will send asap.

thanks!

Hi All,
I've been playing around in pixilang for the last 3 weeks seeing what it can do. I have a couple of questions, the main one is about GIF files. I wanted to try to save something produced in pixilang that had over 256 colours in it and save it to a gif file without losing colour information. I'm working on a Palm, but the concept is the same on Windows. I took an image and created a pixi container three times the original image's size. One section held the red colour info, another the green and the last section the blue data. I also converted all colour data to red. Thus, I always only need a palete that has 256 distinct colours in it at most. What I did looked good. However, when I saved to a gif file I got a surprise. What showed on my screen didn't show up in the gif file. Colour data was lost. This happened on my Windows machine as well. The colour count dropped to 8 in the gif file. Everything I remember seeing about gif files is that it holds a palete of 256 colours, one for each frame of an animation if need be. What happened to the other 248 colours?

I have a question about the documentation as well. I tried to make some minor changes yesterday. These were gone today. I wouldn't mind editing the manual while what I've learned so far is fresh. Does anyone know what went wrong?

My last question is about examples. There are lots of excellent examples with the distribution. However, I have a couple that might be interesting to some. There are good commands for rotating around a 3D axis. Currently,there is a shortcomming with this. You cannot rotate a 3D object since you can only specify the x and y coordinates, but not the z coordinate. I took some code writen in C that draws a 3D object on a screen an allows you to rotate around the object (i.e. move the view point around the object) and converted it to pixilang. I also have a program to draw a circle. This circle can also be turned into an ellipse by using the built-in 3D rotation commands. So, how and where can I post these? Is it even possible without your own website?

Thanks
Mike

Can this be done in PalmOS version?

Of course. Just put data.tar file to folder with your pixi-program.

Thanks Alexander!
