The Animation Nodes are used to control Animation Blocks created in the Animation Editor. They allow the user to play, pause, or stop Animations.

Instance ID

Each Animation Block has an Instance ID, which is a unique identifier that can be set with the Create CustomID Node in the Instance ID Input Socket. The Instance ID is assigned when an Animation starts playing, triggered by the Play Animation Node. The Instance ID then tells either the Pause Animation or Stop Animation Node which Animation is meant to be paused or stopped, respectively.

Another use of the Instance ID is to distinguish between Animations. Two or more Animations without an Instance ID assigned with the Create CustomID Node will have the same default Instance ID and be seen as the same by the system, even if played in parallel.

It is also possible to use an Object ID as an Instance ID.

The default Instance ID for Animations is 42.
