ey up
i was just messing around with ai stuff and quickly came up with this, its a very simple zombie type thing. if you can make use of it feel free.
it will just stand there untill it sees the player, then it will follow, making no allowance for obsacles, all it can see is the players tasty brains.
no need for pathnodes or navmesh as it moves directly to the player location.
the code as it is now it takes health away from the player on contact, health goes no lower than 1.
here are some examples of other things you can do to the player pawn.
replace the line P.Health --;
with 1 or more of the following (assuming your player pawn is extended from UTPawn)
P.CustomTimeDilation = 0.1; //slows down time
P.Destroy(); //kills the player
P.DoJump(true);
P.Gasp();
P.GroundSpeed *=2; //double walking speed
P.InitRagdoll();
P.SetDrawScale(0.5); //half size
P.SetPhysics(PHYS_Flying); //make me fly
P.SetPhysics(PHYS_Spider); // i can climb walls!
P.ForceCrouch();
if you have question please ask on this thread
more than likely someone can give you a better answer than i can.
have fun getting them stuck places.
