Zombots Mod

[randall]

Forget the navmesh, use waypoints for pathfindig. I think its easier to programming and maybe faster (in CoD) than navmesh. Actually i tried IzNoGod's alpha version botmod, and mine waypoint-based mod seem to be faster. It's not laggy with 24 bots and 16 players.

For pathfinding use A*, there is a script in iw_07.iwd/maps/_astar.gsc. Save in array the all paths between waypoints. If you have done with these functions, you're over the worst.

In next step you have to spawn bots, and find the optimum (shortest) path to player.

My tip:
Save resources where you know. For example use distanceSquared() instead of distance(). Function distance() includes squareroot, and it needs lot of memory.
