I am currently using a premade script to play animations when sat down.
seat = script.Parent
function added(child)
if (child.className=="Weld") then
local human = child.part1.Parent:FindFirstChild("Humanoid")
if human ~= nil then
anim = human:LoadAnimation(seat.sitanim)
anim:Play()
end
end
end
function removed(child2)
if anim ~= nil then
anim:Stop()
anim:Remove()
end
end
seat.ChildAdded:connect(added)
seat.ChildRemoved:connect(removed)
However, when having animations including the legs, the legs do not seem to play when everything else is.
