NPC/Rig doesn't play idle animation

  1. What do you want to achieve?
    I am trying to get an NPC to do an Idle animation.
  2. What is the issue?
    The NPC still doesn’t do the animation, no errors and it is a rig inserted from the Plugin made to insert rigs by Roblox themselves. The NPC still stays in this idle:

  1. What solutions have you tried so far?
    I’ve tried using different NPC’s, didn’t work for some reason as well. I’ve also tried different animation scripts.

Any help would be appreciated, thanks!

Solution:
Script: local anim = script.Parent:WaitForChild(“Animation”)
script.Parent:WaitForChild(“Humanoid”):LoadAnimation(anim):Play()

Are any of the NPC’s parts anchored? If so, make them unanchored and anchor just the HumanoidRootPart.

May I see your animation script? That could also be the problem.

I un-anchored everything, but it still doesn’t play it.
The animation script:

	local child = parent:findFirstChild(childName)
	if child then return child end
	while true do
		child = parent.ChildAdded:wait()
		if child.Name==childName then return child end
	end
end

local Figure = script.Parent
local Humanoid = waitForChild(Figure, "Zombie")

If you just want to make it play an idle animation, create a new ServerScript with the following contents:

local anim = script.Parent:WaitForChild("Animation")
script.Parent:WaitForChild("Humanoid"):LoadAnimation(anim):Play()

This will load an animation parented to the same parent as the script and play it on the humanoid.

Inserted a script into server script, typed in the code you told me to, and it didn’t work.
Am I supposed to keep the previous animation script?

You parent it to the NPC, and place an animation object with your desired ID parented to the NPC.

Still doesn’t work, same script, did what you told me to.

Parented to the NPC, not the script.

Still doesn’t work somehow, I’ll send a gif of the entire NPC.
Edit: https://gyazo.com/59baa8af8941c885a8cbd5a6207c6b7e

If you changed the name of the animation change it in the script, or name it back to Animation.

I’ve had issues with Roblox inserted rigs not playing animations, it was resolved when using a Moon Animator generated rig.

Got it, Thank you. And sorry for wasting your time.
