So, BodyVelocity uses the "Global" Axis. I want something like a "Local" Axis version of BodyVelocity. Is it BodyThrust?
Just use BodyVelocity, and to figure out what direction the plane is facing, use:
plane.Body.CFrame.unit
(Vector3)
It represents the direction the part is facing on global axis.
OK. so I got banned for saying L1011s are too awesome. Now can somebody continue telling me what to do?
