        equipR15.AnimationId = "rbxassetid://4967140370"--sets the animation ID
        local equipAnimTrackR15 = hum:LoadAnimation("equipR15")
        equipAnimTrackR15:Play()
    end

    if character:FindFirstChild("Torso") then--if body type is R6
        local equipR6 = Instance.new("Animation")--makes animation instance
