Hello! I was wondering if anyone knew how to limit a character’s arms from moving up too far or too far down shown below.

My code snippet:

RunService.RenderStepped:connect(function(DeltaTime)
	if ToolEquipped then
		if Mouse.Hit.Position ~= nil then
			local RightX, RightY, RightZ = RightShoulder.C0:ToEulerAnglesYXZ()
			local LeftX, LeftY, LeftZ = LeftShoulder.C0:ToEulerAnglesYXZ()
			TweenService:Create(RightShoulder, TweenInfo.new(0.125), {C0 = (RightShoulder.C0 * CFrame.Angles(0,0, -RightZ)) * CFrame.Angles(0,0, math.asin((Mouse.Hit.Position - Mouse.Origin.Position).Unit.Y))}):Play()
			TweenService:Create(LeftShoulder, TweenInfo.new(0.125), {C0 = (LeftShoulder.C0 * CFrame.Angles(0,0, -LeftZ)) * CFrame.Angles(0,0, math.asin((-Mouse.Hit.Position - -Mouse.Origin.Position).Unit.Y))}):Play()
		end
	end
end)

If anyone has done this before please let me know how you were able to achieve it!

You would use math.clamp for this, you might have to experiment with the min and max values as i don’t know what those would be.

local minimumAngle = -10
local maximumAngle = 10
RunService.RenderStepped:connect(function(DeltaTime)
	if ToolEquipped then
		if Mouse.Hit.Position ~= nil then
			local RightX, RightY, RightZ = RightShoulder.C0:ToEulerAnglesYXZ()
			local LeftX, LeftY, LeftZ = LeftShoulder.C0:ToEulerAnglesYXZ()
			
			
			
			local mouseAngle = math.clamp(Mouse.Hit.Position - Mouse.Origin.Position, minimumAngle, maximumAngle)
			
			TweenService:Create(RightShoulder, TweenInfo.new(0.125), {C0 = (RightShoulder.C0 * CFrame.Angles(0,0, -RightZ)) * CFrame.Angles(0,0, math.asin((mouseAngle).Unit.Y))}):Play()
			TweenService:Create(LeftShoulder, TweenInfo.new(0.125), {C0 = (LeftShoulder.C0 * CFrame.Angles(0,0, -LeftZ)) * CFrame.Angles(0,0, math.asin((-mouseAngle).Unit.Y))}):Play()
		end
	end
end)

math.clamp needs a number not a vector3 (Mouse.Hit.Position - Mouse.Origin.Position).

Try this?

local minimumAngle = -10
local maximumAngle = 10
RunService.RenderStepped:connect(function(DeltaTime)
	if ToolEquipped then
		if Mouse.Hit.Position ~= nil then
			local RightX, RightY, RightZ = RightShoulder.C0:ToEulerAnglesYXZ()
			local LeftX, LeftY, LeftZ = LeftShoulder.C0:ToEulerAnglesYXZ()



			local mouseAngle = math.clamp(math.asin(((Mouse.Hit.Position - Mouse.Origin.Position).Unit.Y, minimumAngle, maximumAngle))

				TweenService:Create(RightShoulder, TweenInfo.new(0.125), {C0 = (RightShoulder.C0 * CFrame.Angles(0,0, -RightZ)) * CFrame.Angles(0,0,mouseAngle)}):Play()
				TweenService:Create(LeftShoulder, TweenInfo.new(0.125), {C0 = (LeftShoulder.C0 * CFrame.Angles(0,0, -LeftZ)) * CFrame.Angles(0,0,-mouseAngle)}):Play()
		end
	end
end)```
