Hmm... you are blitting a picture which is 1x1? If picture is a color (int), you should use putpixel(foreground, bomb[a]->x, bomb[a]->y, bomb[a]->picture). If it is a bitmap... hmm... a 1x1 bitmap is a waste of memory.

I see no reason to delete array of bomb[] in your code.

What you're doing is creating the bombs (elsewhere), moving it one frame, check for collision, displaying it, blowing the bomb class variables away, creating a new set that gets initialized to the starting point (if initialized at all), moving it one frame, check for collision, etc.

The bombs won't move because your replacing the bombs with a fresh set of bombs still at the starting line every frame.

What you seem to want to do is erase graphically where the bombs used to be. Just store their previous locations and in each frame, draw over their previous locations with the background and then copy the new locations into the previous location variables.

ouch... when you delete the bomb array, you never reallocate it. so when you try to assign pointers to the places in the bomb array you'll get a memory error. (invalid pointer)

Just don't delete the bomb array, and instead:

      if( check) 
      { 
        for (int a=0; a<10; a++) 
        { 
          delete bomb[a];
          bomb[a]=new Bomb(a); 
        } 
      }

or even just make a method to reinitialize the bombs:

    if( key[KEY_SPACE]) 
    { 
      for (int a=0; a<10; a++) 
      { 
        bomb[a]->Move(); 
        check=bomb[a]->Collision(foreground); 
 
        blit( bomb[a]->picture, foreground, 0, 0, bomb[a]->x, bomb[a]->y, 1, 1); 
        bomb[a]->reinit();
      }
    }

and as for making your bitmap transparent, do you mean translucent? or just seeing through areas that are marked with a special color?

I know transparent color is 0 but how do I make the white parts of my BITMAP transparent?

Ive tried reading through every pixel in the bitmap and checking to see if it was white, if it was I made it 0

Did I do it wrong?
Plz help

Ok, it works, the white part is transparent
But there is one problem remaining...when I press space the program crashes ><

I should really pay more attention to my code

It was something like this, I kinda changed my code and forgot what it was -.-

I assume check is supposed to be checked for every bomb, but it'll only check the last with that code. You may want to move the if(check) bit into the for loop, wouldn't you?

I changed my code to the following:

It still crashes when I press space

Is bomb[n]->picture a valid bitmap?

[edit:] Chris: I didn't notice he started asigning something to check... [/edit]

yes bomb[a]->picture is a valid bitmap, I moved the if statement( not like it was gonna change anything)

hmmmm...what could possibly be the problem...

Im gonna post my entire code, maybe that'll help

Time to goto sleep, goodnight

Try some commenting out. Does it crash if you comment out check = bomb[a]->Collision(foreground)?

EDIT: Dang, Tom beat me to it I went and made sure you had enough elements, but I missed that.

...I was pretty sure I had intialized them...
Anyway it works now! thx alot

gotta pay more attention to my code ><
