Sitting animation showing on server view but not the client

synical4 · March 24, 2021, 5:58pm

The sitting animation will not play on the players screen, but will on the server view.

This is the weirdest issue I’ve encountered every while developing. Im using the animate script from this model made by roblox:

https://www.roblox.com/library/187789986/Drooling-Zombie

The NPC is an R6 rig inserted using the rig builder plugin that comes with studio.

Client View (ALSO LOOKS LIKE THIS WHEN PLAYING THE GAME NORMALLY)

Server View:

	end

Why don’t you just use Humanoid:LoadAnimation()?

I just noticed it’s deprecated now? Umm I don’t know an alternative tbh

Example:

local humanoid = script.Parent -- script in StarterCharacterScripts
local track = Instance.new("Animation", script)
track.AnimationId = "rbxassetid://urid"

humanoid.Seated:Connect(function(s)
    if s then
        local load = humanoid:LoadAnimation(track)
        load:Play()
    end
end)

Problem: I don’t think its an actual animation, I just didn’t know what to call it. Let me show you how the script loads it:

function moveSit()
    RightShoulder.MaxVelocity = 0.15
	LeftShoulder.MaxVelocity = 0.15
	RightShoulder:SetDesiredAngle(3.14 /2)
	LeftShoulder:SetDesiredAngle(-3.14 /2)
	RightHip:SetDesiredAngle(3.14 /2)
	LeftHip:SetDesiredAngle(-3.14 /2)
end

and

elseif (pose == "Seated") then
	stopAllAnimations()
	moveSit()
	return

steven4547466 · March 24, 2021, 6:32pm

The alternative is Animator:LoadAnimation()

synical4 · March 24, 2021, 6:48pm

Welp, it isn’t what I really wanted but it works as my solution. I just made a perfectly identical animation that looks like the normal roblox r6 sit. It shows on the client so its really all I needed.
