I'm using SDL. The menu surface isn't blitting in my code, so all I have is a blank screen that I have to kill the process of, because I haven't put in code so you can "X" out of it. I have narrowed it down to the function that is causing the problem. I have tried using different coordinates, but still nothing. Do I need a while(&event) loop? Although that comes after the problem.
Anyways, here's the relevant bits of code.
The problematic function
void startMenu()
{
int choice = 1;
blitSurface(220, 160, menu, screen);
while(true)
{
if(event.type == SDL_KEYDOWN)
{
if(event.key.keysym.sym == SDLK_UP)
{
choice++;
if(choice > 3)
{
choice = 1;
}
}
else if(event.key.keysym.sym == SDLK_DOWN)
{
choice--;
if(choice < 1)
{
choice = 3;
}
}
else if(event.key.keysym.sym == SDLK_RETURN)
{
break;
}
}
//redraw menu
}
switch(choice)
{
case 1:
//gameStart();
break;
case 2:
//gameOptions();
break;
case 3:
//menuQuit();
break;
}
}
and blitSurface(), because there's always the chance it's been written wrong
[source lang="cpp]
void blitSurface(int x, int y, SDL_Surface *foreground, SDL_Surface *background, COLOR color = NONE)
{
SDL_Rect position;
SDL_Rect clip;
position.x = x;
position.y = y;
if(color != NONE)
{
clip.x = 0;
clip.y = color * 32;
clip.w = 32;
clip.h = 32;
SDL_BlitSurface(foreground, &clip, background, &position);
}
else
{
SDL_BlitSurface(foreground, NULL, background, &position);
}
}
