If an AnimationTrack is created on the server, and properties such as AnimationTrack.Looped or AnimationTrack.Priority are set (on the server), then when the AnimationTrack replicates to the client, those properties appear to replicate when read from the instance and printed; however, the behavior does not replicate.
For example, if the following code is ran on the server:
local Animation = Instance.new("Animation")
Animation.AnimationId = "http://www.roblox.com/asset/?id=3695300085"
local RunService = game:GetService("RunService")
game.Players.PlayerAdded:Connect(function(Player)
Player.CharacterAdded:Connect(function(Character)
while Character.Parent ~= workspace do
RunService.Stepped:Wait()
end
local Track = Character.Humanoid:LoadAnimation(Animation)
while Track.Length == 0 do --wait for animation to load
RunService.Stepped:Wait()
end
Track.Looped = true
Track.Priority = Enum.AnimationPriority.Action
print("[Server] Priority: "..tostring(Track.Priority))
print("[Server] Looped: "..tostring(Track.Looped))
Track:Play()
end)
end)
And this code is inserted into a LocalScript under StarterPlayer.StarterCharacterScripts:
script.Parent.Humanoid.AnimationPlayed:Connect(function(Track)
if Track.Name == "Animation" then --to ignore default character animations
print("[Client] Priority: "..tostring(Track.Priority))
print("[Client] Looped: "..tostring(Track.Looped))
end
end)
The following output is produced:
[Server] Priority: Enum.AnimationPriority.Action
[Server] Looped: true
[Client] Priority: Enum.AnimationPriority.Action
[Client] Looped: true
Indicating that the AnimationTrack.Priority and AnimationTrack.Looped properties should have replicated. In reality, they are not replicated, and the AnimationTrack is overwritten by the default walking animations, and it does not loop.
Note that this bug has nothing to do with the animation not being loaded yet, as I wait for the AnimationTrack to load in the above code.
To get the behavior of the properties to replicate, the following code is necessary in that same LocalScript:
script.Parent.Humanoid.AnimationPlayed:Connect(function(Track)
Track.Priority = Track.Priority
Track.Looped = Track.Looped
end)
Now, the behavior replicates as expected.
I’ve included a repro place with the above code. Uncomment the lines in the LocalScript to fix the bug
