GLBasic - en / GWC Zero
« on: 2016-Mar-12 »
Hello

I am wondering whether it is possible to use GLBasic to build a game for the open console GWC Zero?

Possibly via the Linux plateform support?

Regards

GLBasic - en / Graphic bug I can't understand!
« on: 2010-Jul-28 »
Dear all,

I need your help to explain me the bug I found.

The attached file is the source of the game I wrote "SimOniZ".
THe attached version has no problem... after I discovered a workaround for the bug.

In the source files, I declares global constants for the sprite ids of the grafix components.
e.g. in the play.gbas file
Code: GLBasic [Select]
// grafix components
GLOBAL GFX_GREEN%       = 0 ;  // Green button
GLOBAL GFX_YELLOW%      = 1 ;
GLOBAL GFX_BLUE%        = 2 ;
GLOBAL GFX_RED% = 3 ;
GLOBAL GFX_PAUSE%       = 4 ; // Pause button
GLOBAL GFX_STATUS%      = 5 ;
GLOBAL GFX_FONT15%      = 100 ;
 

To reproduce the bug, open the project and edit the credits.gbas file
Code: GLBasic [Select]
//-----------------------------------------------------------------------------
// C O N S T A N T S
//-----------------------------------------------------------------------------

// menu states
GLOBAL MS_NONE%         = 0;
GLOBAL MS_BACK%         = 1 ;

// grafix components
GLOBAL GFX_BACK%        = 0 ;   // Bouton "Back"
GLOBAL GFX_FONT15%      = 100 ;

Replace the line
Code: GLBasic [Select]
 GLOBAL GFX_FONT15%     = 100 ;
by
Code: GLBasic [Select]
 GLOBAL GFX_FONT15%     = 1 ;

This change generates the following problem:
* in the play screen, the yellow button is not displayed
* in the pause screen, the abort button is not displayed

Doing the same change in the highscores.gbas does not cause the bug!

I am completely lost.

Thanks for the time you will spent to explain me what is going wrong!

Hello,

Is it possible to define variables local to a source file, i.e. only accessible by functions defined in the same source file?

Thank you.

Hello

I am running GLBasic under Windows 7 64bits Home Edition. When trying to compile a game for GP2X-WIZ, g++.exe crashes and I get a dialog box warning me that g++.exe has stopped working.

When I run GLBasic under a virtualized windows XP on the same machine, everything works fine.

Regards

Here is the output

GLBasic - en / Sound Duration
« on: 2008-Sep-07 »
Hello all,

I am looking how to handle the duration of a sound.
The idea is to play a sound (a beep) when the player touch the screen (on a GP2X). As long as the player keeps touching the screen, I want the sound to be played without interruption. When the player releases the screen, then the sound stops.

It should sound like:

beep (short)
beeeep (longer)
beeeeeep (even longer)
beeee..........eeeeeeep (very long)

Thanks for your help!

GLBasic - en / GLBasic Logo...
« on: 2008-Sep-07 »
Hello,

Is there GLBasic logos available for download.
In the Credits screen of the game I am currently developping, I would like to add a GLBasic logo.
Ideally, the logo should be in SVG format so we can resize it at will with inkscape :)

Regards

GLBasic - en / CLOSEFILE: error in the help
« on: 2008-Sep-07 »
Hello marvellous GLBasic developpers....

I would lke to mention an error in the help file for the command CLOSEFILE:
the help file mention the following syntax:
Code: GLBasic [Select]
CLOSEFILE(channel#)
 
while it actually is
Code: GLBasic [Select]
CLOSEFILE channel#
 
without parentheses.

I mention this because it took me some times before to find this out...

GLBasic - en / FOR and FOREACH
« on: 2008-Sep-06 »
Hello all,

In the help, I read for "FOREACH" the following
Quote
FOREACH ref in feld[]
...
NEXT

During the loop, "ref" will be a pointer (BYREF) variable to each element in the array.
You do not need to define "ref" as LOCAL.
It will be done automatcally, and it will invalid after the corresponding NEXT command.

I am wondering wether it is also the case with the "FOR" command: do we need to define the counter as LOCAL or is it done automatically?

Best regards

François

I would like to announce the very soon availability of SimOniZ for GP2X (F100 & F200) with full support of the touchscreen on the F200.

Pictures are available here

Of course, it is being developped with GLBasic... ;)

Hello,

I am wondering how to define a local array within a function.
I tried this
Code: GLBasic [Select]
LOCAL DIM myArray[10];
 
but this does not work. If i left out the word LOCAL, then it looks ok. Is it normal? Is myArray still local?

Secondly, is it ok to return a local array from a function like this:

Code: GLBasic [Select]
FUNCTION BuildSequence: pLevel
        // These values are defined LOCAL:
        // pLevel
        DIM tSequence[pLevel+2];

        FOR i = 0 TO pLevel+1
                tSequence[i] = RND(7);
        NEXT
        RETURN tSequence
ENDFUNCTION
 

How should the "receiving" variable look like?

Thanks for your help.

Hello,

How can I get the serial number of the gp2x on which the game is running? I would like to develop an "on line" score system. Of course, the GP2X does not support network gaming (as far as I know), but the idea is to generate a code base on the serial number and the score. The player then enters the code on the web site. The code is interpreted and the 'on line" scores are updated!

BTW: Anyone knows how I could develop the appropriate algorithms?

Thanks a lot!

Hello,

I have started to code a mini-game designed for the GP2X-F200 and facing some performance issues. I beleive this is because I am new on GLBasic AND game programming.
Currently, bombs are just moving on the screen and bouncing against the borders. With 12 or more bombs on the screen moving simultaneously, performance is decreasing sharply.
In the code, I tried to appy "fixed point" calculation instead of "floating point" to improve performance (as the GP2X does not have a floating point unit), but I feel that the way i applied it in GLBasic might be wrong.

Therefore, I would really appreciate if some more experienced game programmers could review my code and explain me what I am doing wrong.

PS: another problem is the  display of png images on the GP2X: the quality is poor compared to a "windows" build

Here is the whole projet in its latest state: bombsorting_build2008042001.rar - 0.56MB

Thanks a lot to those you will help me to improve my skills and the project.

Hello,

With build 5.235, the PLATFORMINFO$ function generates a freeze on a black screen with the GP2X:
The code below only works when commenting the line with PLATFORMINFO$ (the fourth line of code)...

GLOBAL gDevice$ = PLATFORMINFO$("DEVICE");
//IF gDevice$ = "POCKETPC" OR gDevice$ = "F200"
//      SYSTEMPOINTER FALSE; // device with touchscreen!
//ELSE
//      SYSTEMPOINTER TRUE; // device without touchscreen --> simulate pen with the mouse!
//ENDIF
