i would like the enemies in my game to walk around objects such as a cube in order to get to the player instead of walking straigh towards to the player.

currenlty i have used the point object command which simply points the object (enemy) and the player and moves until it reaches the player. although if there was a wall (or cube) in the way any ideas of how i could get the enemy to move around it?

thanks

There are many techniques you can try. The most popular one is called A* (A star.) You can also use a simple look forward and turn code. It depends on the kind of level and obstacles you have. A twisty maze needs A* or way points. A forest of trees or rocks only needs simple obstacle avoidance logic.

Hey! I'll probably need that sometime in my First person shooter game (SAS Elite). DO you think you could right a code so the enemies walk around obstacles and not straight to the player?
Cheers,
Nick.
