Thread: not drawing my bad guys

hi im currently making a game in C++ and SDL and i have collisions working and i was wondering if there was a way to not draw the bad guy when a collision is detected

my code for drawing is

Code:

  for (int i=0; i<size; i++)
        {
                evil[i].draw(surf);
        }

the method draw is

Code:

void Sprite::draw(SDL_Surface *surf)
{
        SDL_Rect rect;

        if(m_hasImage)
        {
                // if an image has been loaded then use that
                rect.x = static_cast<int>(m_x);
                rect.y = static_cast<int>(m_y);
                rect.w = rect.h = 0;
                SDL_BlitSurface(m_image, 0, surf, &rect);
        }
        else
        {
                // Otherwise just draw a red square
                rect.x = static_cast<int>(m_x);
                rect.y = static_cast<int>(m_y);
                rect.w = m_w;
                rect.h = m_h;
                SDL_FillRect(surf, &rect, 0xff0000);  
        }
}

so basically, when a collison is detected., i was wondering if there was a way to not draw the guy other than just set his coordinates way off the screen (which is what i have now)

Code:

if( !CollidingWithAnything())
{
  rest of draw
}

that's 1 way of doing it

You could also give each of your enemies a visible variable which is set to false when there is a collision and only draw enemies who's visible variable is set to true.

yes that is a way but you should just delete it right on the spot to free up system memory as soon as possible

thast what i tried but when i said (if true) draw the sprites but i dont know what to put in for if false because it wouldnt run properly if it didnt know what to do at false

also, my collisions funtion is in my main program and my draw method is in the class, so i sont think i can call collisions in draw
