I'm trying to add collision to the walls in my game but the hitbox moves.

Here's where I make the SDL_rect

           SDL_Rect walls[30];
           walls[0].x = mapX;
           walls[0].y = mapY;
           walls[0].w = 32;
           walls[0].h = 228;

Here's my collision code for the wall.

        if(keysHeld[SDLK_RIGHT])
           {
              for(int i=0;i<30;i++)
              if(collision(&playerC,&walls[i]))
              playerX += 3;
           }

The camera and movment

         	if(keysHeld[SDLK_DOWN])
		{
            batY -= 1;
			if(playerY>= 300)
				playerY+=1;
			else
				camera.y+=1;
		}
		if(keysHeld[SDLK_RIGHT])
		{
		    batX -= 1;
			if(playerX<=640/2)
				playerX+=1;
			else
				camera.x+=1;
		}
		if(keysHeld[SDLK_UP])
		{
		    batY += 1;
			if(playerX<=100)
				playerY-=1;
			else
				camera.y-=1;
		}
		if(keysHeld[SDLK_LEFT])
		{
		    batX += 1;
			if(playerX>=640/2)
				playerX-=1;
			else
				camera.x-=1;
		}

(BatX & Y, just ingnore that.)

Thanks for any help.

Should this not be -= 3?

5	      playerX += 3;

Heres's a picture of when I start and when the Rect is at the right spot. (the blue thinh)


But when I move, it moves


Please help.

It looks as if the background (walls etc.) has moved.
