Your animation might not be working on Roblox due to a few reasons. First, check for ownership issues. The game owner must also own the animation. If the game is under a different account or group, it won’t play. Make sure the animation is uploaded to the correct account or group.
Another common issue is anchoring. Ensure that the rig is not anchored, as this can prevent the animation from playing. Also, check your Roblox Player settings. Sometimes, the settings might override the animation, causing it not to work.
Cache issues can also cause problems. Clear your cache, as a corrupted cache can disrupt the animation. Scripting errors are another possible reason. Verify that the script is loading and playing the animation correctly. Use the `Animator` inside the `Humanoid` for the best results.
Lastly, consider the animation priority. If the priority is too low, the animation might not play. For group games, ensure that animations are uploaded to the group with correct priorities. By addressing these issues, you should be able to fix your animation problem on Roblox.
