Hey guys I was wondering: How do you make it so that ai like an elite start in a Wraith like one does on Assualt on the control room (B40) (Note: Not make them spawn out of the vehicle, make them spawn in the vehicle)

Scripts. From Bungie's scripts for b40:

(vehicle_load_magic crev_ent_wraith_b "driver" (ai_actors ext_a_area_c_cov/wraith_b_pilot ))

There may be other methods and commands, but you asked how the elite spawns inside a wraith like the one on b40
