Hullo. I would like a little help with something. I've written a simple
collision-detection program, but I need a little clarification with
something:


for(int a = 1; a <= pptest_w; a++){
   for(int b = 1; b <= pptest_h; b++){
      pixelcheck = getpixel(pptest_1a, a, b);
      if(pixelcheck <= 0){
      }else if(pixelcheck != 0){
         pixelcheck = getpixel(pptest_2a, a, b);
         if(pixelcheck <= 0){
         }else if(pixelcheck != 0){
            collide = 1;
            break;
         }
      }
   }
}

FUNKtion();

I would like to get it to break as soon as a collision is detected and go
straight to FUNKtion(). Is this enough to bust out of all those nested
loops? Putting if(collide){break;} latter in that mess would be kind of
stupid because you're just putting it in another loop, correct? Any help
will be appreciated. Thank you.
