i'm no pro, and havnt even started a project, but do know programming. this may not be the best method, but could work.
idea:
make 4 sensors (plains, 1x1) for the enemy, 1 infront, 1 to left, 1 to right, 1 to back. make them limbs. offset them to a distance you like. use intersect object to detect the walls.
so if there is a wall infront have him move left or right, if theres a wall infront and on left, have him move right, etc.

like i said, possible not the best, but would work. sorry if this method is completly....a waste of coding.

RAWR!

I'm fairly sure Dark A.I has commands for avoidance detection and all that.

Just make a raycast (intersect object command, or better, sparky's dll) come out from infront of the enemy. If that intersects a solid object, turn away.

Dark AI offers you simple avaoidance of all solid objects which you specify as obstacles

Tikkis technique will work fine, but will be pretty performance heavy if you have alot of enemies.

Zotoasters technique is probably the most classic, but to make the enemy in any way intelligent is going to need alot of code.

dark ai sounds cool but im not buying anything else from tgc til they at least update dp. i mean all i want is a character controller that can jump. is that too much to ask??

turning left and right with some kind of dp commands would be cool too instead of the turn object left/right.

u try to have a camera follow using these commands and your camera wont follow right.

anyway ill probablly get dbpx10 when it comes out.(maybe) since i might need a new pc to go with it. :/

You must be doing something wrong then, i've gotten a following camera to work fine, as have many other members.
