Hello,

I need to create a lot of basic objects at runtime, in 3D, so I need to "group" (combine) objects to reduce the draw-calls.
Is there any native function in GLBasic to do that? Or is there someone who was able to create such function?

Thank you for help!

Day by day I'm discovering this great product.
Now I found two "small" problems:

1) How can I include a source code inside another one (something like "include" or "import")?
2) Can I set screen resolution, Fullscreen, more than 1024x768?
3) Does GLBasic support video other than 4:3 (e.g.: 1024x600? 1440x900? 1680x1050?)

Thank you!

Hello,

I cannot find a function to change screen resolution via code, how can I do it?
(for example, I want to let the user change game resolution).

Thank you (even without restarting the game!)

Hello, I'm new in GLBasic, and this is my first official post!  :booze:

I wish to give my contribute in calculation optimization (tricks!).

1) I noticed that many people, to get a sprite rotating (forever!), they use something like this:

Code (glbasic) Select

counter = 0
while true
  inc counter, 1
  if counter >= 360 then counter = 0
wend


Even if it is correct, using an if is usually a "slow" procedure. Istead, you can use this code:

Code (glbasic) Select

counter = 0

WHILE TRUE
INC counter, 1

PRINT MOD(counter, 360), 100, 100

SHOWSCREEN
WEND


In this way, the "mod" makes the "dirty" job, and it is faster than using "if".

Another trick is about values switching:

1) true -> false -> true ....
2) 1 -> 0 -> 1 -> ......

You can use the following code:

BOOLEAN:
Code (glbasic) Select

boolValue = FALSE

WHILE TRUE
boolValue = bNOT(boolValue)
PRINT boolValue, 100, 100

SHOWSCREEN
WEND


FOR "1" AND "0" ......

Code (glbasic) Select

boolValue = 0

WHILE TRUE
boolValue = 1 - boolValue
PRINT boolValue, 100, 100

SHOWSCREEN
WEND


In order to see the result, you can put, in the first line, an FPS limiter:

Quote
limitfps 3 ; 3 frames per second.

I hope this small tutorial will help some people! (my 0.02$ contribution!)

Hello,

I'm evaluating some tools to make a game.
Since I need to make a game, I wish some "objective" information to better understand if GLBasic is the right tool, or if is better that I look for other programs.
I tried to find these information in the forum and in the web, but it is hard to get definitive answers (I hope you could help me).
First of all, I want to say that I'm a programmer. I need to create a game with 2D top-view (not isometric, but with camera seen on top).
Basically I want to make a 2D application (with editor, and modding features, and implementing "newLisp - http://newlisp.org" as scripting language), but using 3D sprites (to better move, rotate and render the vehicles and other things).
Obviously, I know that something can be done, but I'm alone, so I hope I can do them without too much workload (I need some pre-made functionalities, just to speed-up my job).
So...

1) Can I create 2D tiled backgrounds with sprites in 3D? (real 3D sprites model over a 2D tiled background).
2) Can I implement a physic engine without too much workload (newton physics? ODE? Chipmunk 2d? or... ?)
3) Can I realize viewports (I need to get more "views" of the game in the same screen. For me a view is a "window" inside the game. Two views are like two camera working at the same time).
4) Can I work on a sprite canvas (or other images) in real time (to apply some special effects)?
5) Can I insert C code in the source code (like one do with assembler)?
6) Can I apply light effects in real time (like day-cycle)? Yes I know I'm talking about 2D game, but some nice light effects could be applied also. And can I realize a kind of shadows?
7) When I load an image, does it automatically go in the video card RAM, or I can manage that process manually (e.g.: I want to load some sprites in background, with a thread, then I "send" only needed images to the video card, after a CPU preprocessing and only when needed, just to avoid to fill video card memory).
8) Which direct X version use PB? (DX3? DX7? DX8? DX9?)

I know I made many questions, I'm sorry, but I really need such answers in order to avoid to spend many months with the wrong tool.

I found possible alternatives, but PB seems very good:
1) Pure Basic(but it seems more general application oriented, not much game oriented).
2) Blitzmax (but its development seems blocked, only updates are made).
3) I use Delphi in my official job, but I cannot find any good, updated library to make the games.
4) Play Basic seems not really compiled (I made some tests and the p-code seems slow).

Thank you to everyone for your patience!
