STL Problem

Alright. I''ve run in to a problem with my STL list, and was wondering if you people could help me out. So, I have a class defined like so: class PROJECTILE { public: PROJECTILE(); ~PROJECTILE(); void insert(Sint16 x, Sint16 y); void update(); void draw(SDL_Surface *screen); private: list plasma; list::iterator iterP; Uint8 speed; }; The STL list contains a list of pointers to this class: class PLASMA { public: PLASMA(Sint16 x, Sint16 y); /* Used to spawn bullets at the x y coords*/ ~PLASMA(); int update(); void draw(SDL_Surface *screen); SDL_Rect rect_plasma; private: Uint8 speed; SDL_Surface *temp_plasma, *plasma_bmp; }; Now, I go through my list in the projectile class function update() and update the location of the plasma projectile, and check to see if it has left the screen yet. If it has, I will return 1, and it will be removed from the list, else it shall return 0 and nothing shall happen to it. void PROJECTILE::update() { iterP = plasma.begin(); while(iterP != plasma.end()) { if((*iterP)->update() == 1) { plasma.remove(iterP); } else { iterP++; } } } int PLASMA::update() { rect_plasma.y -= speed; if(rect_plasma.y <= 0) { return 1; } else { return 0; } } Now. The problem I run in to, is it crashes when I try to remove the object from the list (When it reaches the edge of the screen). I believe I must be doing something wrong -AfroFire
