Reproduction Steps
Currently, as of 3/10/22, the Workspace.AnimationWeightedBlendFix property infinitely hangs concurrently running animations, even if they are at a different priority. This results in code that relies on those animations completing infinitely yielding, which causes game-breaking bugs.
Steps to reproduce:
- Open up the repro place file I have attached privately to this bug report (repro contains game specific code that cannot be posted publicly)
- Observe that
Workspace.AnimationWeightedBlendFixis set totrue - Run a playsolo test.
- Climb up one of the green parts
- While on a green part, click on the “play hurt animation” button. Observe that
trueis being logged to the output to indicate that code is waiting for the hurt animation to finish playing. - Observe that the animation never finishes playing, and that the code is infinitely yielding.
- Jump off of the green part. Observe that the hurt animation plays and the code logs
falseto the output. - Stop the playsolo test. Set
Workspace.AnimationWeightedBlendFixtofalse. - Repeat steps 3 through 4.
- Click the “play hurt animation” button. Observe that
trueis logged to the output for a bit, thenfalseis logged since the animation completed playing and the code resumed execution.
Expected Behavior
It is expected that an animation would play as normal code-wise and not infinitely hang, regardless of it is visually being overlapped by another animation or not. This is expected behavior, as stated by @AllYourBlox (Animation Engine - Runtime Changes and Fixes - #358 by AllYourBlox).
Actual Behavior
An animation that is being overridden by another animation can infinitely yield if Workspace.AnimationWeightedBlendFix is set to true.
Workaround
Setting Workspace.AnimationWeightedBlendFix to false.
