How can i make so that your spawn with your character's arms togheter like a straight jacket?
use the animation editor to make a looping 1 keyframe "animation" of the pose and use a script to play the animation on CharacterAdded. if you want more functionality beyond just the pose then you'll need to script it too.
ex: (serverside script in starterplayerscripts)
local player = script.Parent local straitjacketPose = player.Character.Humanoid:LoadAnimation(game.ServerStorage.straitjacketPose) player.CharacterAdded:Connect(function() straitjacketPose:Play() end)
