Accessible from the targets screen.

Configures a controller for the current animation.

Parenting

This works like the built-in controller "Physics Link" option, however it offers to helpful advantages.

1. The parenting is local to the animation. This means you can make a controller parented to something for one animation, and parenting it to something else for another. This also means parenting will blend smoothly from one animation to the next.
2. It can be weighted (see below).

Options

Control position/rotation

If toggled off, Timeline will not affect the target controller at all for this property.

Weight

This determines how much will the animation affect the controller position. For example, if you set the weight to 50%, it means every physics frame will move the node only halfway to where the animation should be.
