sword/fist fighting a.i code.... - 08/01/08 15:24
ok...i was working on converting/combining two a5 scripts to a6 that were contributions from another site. i was able to get it running with no errors, but my dilemma is, when the main character approaches the enemy model, the enemy turns away, and then follows the player model around. i dont understand what's wrong. i am no coder, so can one of the great code masters please look at this and tell me whats wrong? i would like to contribute this to the community so us coding noobs can have a easy a.i. to play with.
Thanks in advance, Blink.
