Controls the rotation of an Actor along a Track.
The direction the Actor would be pointing at each Rotation keyframe is indicated with an arrow. Click buttons in the dialog to choose which rotation axis is edited. Only Tween or Accelerated rotation timeline types can have a their rotations controlled through this mode. Any other rotation timeline types cannot enter Edit Direction mode. The shape of the Track depends on the movement timeline for the selected Actor.
Direct - The Direction the Actor is pointing at keyframes on the track is adjusted by clicking on a keyframe arrow to pick it up. Move the mouse and the direction arrow will pivot Round, Up/Down or Bank left/right. Click again to release your hold on the arrow. If a non-keyframe frame indicator is selected you will be prompted with the option to make it a keyframe.
Time Shift - Adjusts which frames are the keyframes in the selected Actor's rotation timeline. Click on the keyframe arrow to pick it up. Move the mouse left or right to shift the keyframe to an earlier or later frame. Click again to set the arrow down. This is like slipping beads up or down the string running through them.
Delete - Demotes a Keyframe to a normal frame.
Tension - This only applies if the Rotation timeline is of Accelerated type. If it is then in this mode the direction arrow can be made to "behave less elastically". Click on the keyframe arrow to pick it up. Move the mouse left or right to adjust the tension in the spline "elasticity in the arrow directions". Click again to set the arrow back down. This is like tightening or loosening the string running through the selected bead.
