I''m working on a game in c++. I want a collision detection method that looks like this:- detect_collision(player p, enemy e){ if(one of the enemy''s bullets overlaps with the player) kill the player; if(one of the player''s bullets overlaps with the enemy) kill the enemy; } If I write this method and call it from within the main game loop, for the player and each enemy, the collision detection dosen''t work, however, if I cut and paste the code into the main loop (where p and e are directly available) the program works fine. What''s going on? thanks in advance. felix.

You passed the parameters in a wrong way!

You should try this ( so just change the function header! ):

detect_collision( player &p,enemy &e ) // &p and &e are
{ // references!
....//your code

Your problem was ( is? I don''t hope so! ) that you created two new objects ( enemy and player )in each function call. So you just changed the state of this new objects and not the state of the two ones you passed to the function!

If you have more trouble, call me:
