im trying to get this collision detection working(it should), but when i try to check for a collision(dont know if it works) and then when i try to render the sprite i get a unhandled exception here is the code that i use to check for collision
bool spritecollide(AnimatedSprite s1, AnimatedSprite s2)
{
if (( s1.posx > s2.posx ) && ( s1.posx < (s2.posx + s2.framesizex )) && ( s1.posy > s2.posy ) && ( s1.posy < s2.posy + s2.framesizey ))
return true;
return false;
};
and here is where the unhandled exception occures
result = sprite->Begin(D3DXSPRITE_ALPHABLEND);
ive attached my sprite class, ok, i was told; You aren't permitted to upload this kind of file, so ill just p[aste the code
