Method PlayAnimation

trinity/Eve/Turret/EveTurretSet.cpp:2578–2756

-------------------------------------------------------------------------------- Description: Play an animation to a single turret Arguments: turretIndex - which turret is going to get this anim animName - animation name like it says in the gr2 file, which will be played now animNameIdle - animation name like it says in the gr2 file, which will be played in loop after animName delay - wait time in

//   Length of animation in seconds or 0.f if error
