AnimatorJobExtensions.AddJobDependency

Parameters

Description

Creates a dependency between animator jobs and the job represented by the supplied job handle. To add multiple job dependencies, call this method for each job that need to run before the Animator's jobs.

After each update the Animator dependencies are flushed.
