v1.16.201

Summary:

When playing a looping particle effect in a state of an animation controller, and then turning off the animation controller with a MoLang expression, the particle effect keeps playing even though the animation controller is no longer active.

Impact:

Makes it more difficult to create certain animations that rely on particles

Repro Steps:

1. Install the attached resource pack (the pack contains a demo using a cow and an is_on_ground query)
2. Join a world with the resource pack installed
3. Spawn a vanilla cow
4. Punch the cow so that it loses ground contact

Observed Results:

The rainbow effect starts playing when the cow loses contact to the ground, but does not stop when the cow lands again. Instead it plays indefinitely.

Expected Results:

The particle effect should start playing when the cow loses contact to the ground, but stop immediately when it's on the ground again.
