-Now when you turn, the cubes become diagonal. -The bug which caused some blocks that are farther to appear on top of the closer ones is fixed. -Before the speed increases, a "Speed Up!" sign appears. -Between 2 "levels", there is a corridor made of cubes.
Should I keep my little square for the player or should I create a sprite ?
As usual, I've attached a TNS file which contains the code. Could someone please extract the code ? Thanks !
DJ_O : The function gc:fillPolygon() could be used, it would be quite easy. Thanks for the avi btw !
Jonius7 : The corridor would be harder... Well, I would have to create levels instead of random cubes. But I could do this. And your latest screenie is great ! Thanks !
Thank you for the code ! And yeah, I need to fix 2 or 3 things.
DJ_O : I really don't understand that bug... NVM, fixed And I'll try to make cubes more diagonal when you turn. It shouldn't be hard, but It will decrease the framerate a bit.
Jonius7 : Thanks for the screenshot ! But it looks kinda weird... The framerate is really low and the grey squares don't show up...
Anyway, I'm going to add the TNS document and Jonius7's screenshot to the first post. Could someone tell me if the document works for OS>=3.0.2 ?
I hate school, I don't have enough free time to work on my games. (Yeah, I have a lot of simultaneous game projects) But I managed to get a playable CubeField clone...
So basically you just have to avoid cubes When you reach 1000, 2000, 3000... points, the speed increases and the colors change. The 3D projection is not really realistic, I'll have to work on it. And I also have to add a nice sprite for the player's ship.
But you still can have fun with this... (My highscore is 5600 points ! Can you beat it ?)

FINAL VERSION !
-There is a nice sprite for the player -The corridor is more regular

New final version The 3D projection is now more realistic. A little bugfix

Now the speed of the cubes automatically adapts to the framerate. So the speed is the same on CX, clickpad, or computer software.

nGfx will certainly be really useful ! But I think that Lua IDE won't be a revolution. OCLua is great... Maybe that keywords highlighting would be useful. And there are already several bitmap->ti.image converters. An on-calc one would not be useful... (And I even don't think that it is possible, because where would you store bitmaps ?)
