How do I make a animation and put it on the ROBLOXian?

I don't know which animation you are talking about, the plugin or by script. In this case, I will show you how to do it by script

plr = game.Players.LocalPlayer
char = plr.Character
larm = char["Left Arm"]

for i = 1, 10 do
larm.CFrame = char.Torso.CFrame * CFrame.new(1.5, 0 ,0) * CFrame.Angles(i*9, 0, 0)
wait()
end

That would make your arm swing around somewhere. I hope this helped.

I think that you could make a script that removes the players animation script when it respawns then clones your one with the animation into the charicater. To make your own one. I suggest that you take ROBLOX's own one that you spawn with, edit it (put your ID's inplace) then use that as your own.

I hope this works. :)

So Joemum33, where would you put this sciript? in the starter gui??
