Hiya Sorry about all of the posts lately, but im comming up with more and more questions as I continue me project. Ive read a lot of different articles on AI and most of them talk about entity contollers. Ive gone thru gamedev and read a few articles on them, but im still kinda in the dark as to there importance and or what they even are. Along with controllers comes the term triggers. I understand triggers, there basicly like a if/else statement. (if(player.pos == carspawner.pos) spawn car entity into world) How though do you "apply" them do an object? What all are controller classes used for? Also, how do state machines work with controllers? (Should I have posted this in the AI section ... ) cheers to all! ~yodaman
