I've been away from B3D for a bit (trying to reacquaint myself) and need some help with the following code (Loki's homing missile code).

I don't see where the arrays are defined? (trailx[], traily[], trailz[], trailpitch[], trailyaw[], trailroll[]).

Aha... looks as if all the backslashes got stripped out of the html when the code was pasted. Boy oh boy...
