Is there any way you can check if dbDot do collision with a enemy?

heres code

+ Code Snippet

#include "darkgdk.h"
#include "Dinput.h"

struct BULLET{
   bool Active;
   float x,y;
   float dx,dy;
   void Update(void);
}Bullet[500];

void BULLET::Update(void){
   x+=dx;
   y+=dy;
   dbDot(x,y);
}
void WeaponM4Fire(void)
{
  for (int i=0;i<500;i++){
      if (Bullet[i].Active) Bullet[i].Update();
	  if (Collision?)
	  {
			Bullet[i].Active=false;
	  }
  }
   if (dbKeyState(DIK_W) == 1){
	   int i=0;
     while ((Bullet[i].Active)&&(i<500)) i++;
     if (i<500){
        Bullet[i].Active=true;
        Bullet[i].x=(dbSpriteX(1)+20);
        Bullet[i].y=(dbSpriteY(1)+20);
        Bullet[i].dx=9;
        Bullet[i].dy=0;
     }
   }
}

The purpose of dbDot() is just do draw a pixel at the given screen coordinates. What do you mean with collision?
Maybe you want to check if the pixel at these coordinates is inside a certain area?
If that's the case then just do a comparison like this:

+ Code Snippet

float MinX = 30;
float MinY = 20;
float MaxX = 70;
float MaxY = 40;

if ( MinX < x < MaxX && MinY < y < MaxY )
{
    // Pixel at x, y is inside the area!
}

The fastest code is the code never written.
