Hello,
Yea its me again :)
Ok i made a custom gui: 5 buttons; 2 increase/decrease angle, 2 increase/decrease power attack and one Shot/Fire.
If i press them in random order, and pretty fast/ a lot of times(i mean like i pressed button A 10 time in 2 sec the switched to D pressed it X secs the switched to B and etc), after 30-40 maybe 60 seconds my program crashes.
GDB gave no results, just said something like "the program return 0" don't remember, but no errors not backtrace, looks like the program exited normally.
Here parts of the code:
This part is the part that draws pressed and released buttons and changes values of angle and power (actually the one that cause the crash as i think :\)
//Main Game Loop
while(gameRunning)
{
/*-------Start Event Handle-------*/
while(SDL_PollEvent(&event))
{
//Pressed X
if(event.type == SDL_QUIT)
gameRunning = false;
//Pressed Escape
if(event.key.keysym.sym == SDLK_ESCAPE)
gameRunning = false;
//Or user pressed mouse button
if(event.type == SDL_MOUSEBUTTONDOWN)
{
//if left button
if(event.button.button == SDL_BUTTON_LEFT)
{
mX = event.button.x;
mY = event.button.y;
switch(menu_GetButtonPressed(mX, mY))
{
//Button decrease angle pressed
case 1:
menuState = 1;
angle -= 1;
if(angle <= 0)
angle = 360;
menu_DrawMenu(angle, power, menuPic, 1);
redraw = 1;
break;
//Button increase angel pressed
case 2:
menuState = 2;
angle += 1;
if(angle > 360)
angle = 1;
menu_DrawMenu(angle, power, menuPic, 2);
redraw = 1;
break;
//Button Fire pressed
case 3:
menuState = 3;
menu_DrawMenu(angle, power, menuPic, 3);
redraw = 1;
break;
//Button increase power pressed
case 4:
menuState = 4;
power -= 1;
if(power < 1)
power = 1;
menu_DrawMenu(angle, power, menuPic, 4);
redraw = 1;
break;
//Button decrease power pressed
case 5:
menuState = 5;
power += 1;
if(power > 100)
power = 100;
menu_DrawMenu(angle, power, menuPic, 5);
redraw = 1;
break;
}
}
}
//Or user released mouse button
if(event.type == SDL_MOUSEBUTTONUP)
{
//if left button
if(event.button.button == SDL_BUTTON_LEFT)
{
switch(menuState)
{
//Button decrease angle pressed
case 1:
menu_DrawMenu(angle, power, menuPic, -1);
menuState = 0;
redraw = 1;
break;
//Button increase angel pressed
case 2:
menu_DrawMenu(angle, power, menuPic, -2);
menuState = 0;
redraw = 1;
break;
//Button Fire pressed
case 3:
//Do Fire()
menu_DrawMenu(angle, power, menuPic, -3);
menuState = 0;
redraw = 1;
break;
//Button decrease power pressed
case 4:
menu_DrawMenu(angle, power, menuPic, -4);
menuState = 0;
redraw = 1;
break;
//Button increase power pressed
case 5:
menu_DrawMenu(angle, power, menuPic, -5);
menuState = 0;
redraw = 1;
break;
}
}
}
}
/*-------End Event Handle-------*/

{
if(redraw == 1)
{

menu_GetButtonPressed(mX, mY) - return button that pressed

Thats all i think, i know its a LOOOT of code but i spent almost all day looking for the problem, maybe i tired and missed something, so please i need your help.
