Leaping system not going straight

Help and Feedback Scripting Support
#1

ive been trying to make a system where players can jump around to do a “dash” and i use humanoid.movedirection to dictate where the player is going, only issue is, at some angles it doesnt jump straight

script runcontext client

elseif Humanoid:GetState() == Enum.HumanoidStateType.Freefall then
		Humanoid:ChangeState(Enum.HumanoidStateType.Physics)
		--HumanoidRootPart.AssemblyLinearVelocity *= Vector3.new(0,1,0)
		HumanoidRootPart:FindFirstChild("kerplunk"):Play()
		if Humanoid.MoveDirection.Magnitude > 0.1 then
			HumanoidRootPart:ApplyImpulse((Vector3.new(math.clamp(Humanoid.MoveDirection.X*500,-50,50),math.clamp(Humanoid.MoveDirection.Y*500,-50,50),math.clamp(Humanoid.MoveDirection.Z*500,-50,50))+Vector3.new(0,10,0))*10)
		else
			HumanoidRootPart.AssemblyLinearVelocity *= Vector3.new(1,0,1)
			HumanoidRootPart:ApplyImpulse(Vector3.new(0,-600,0))
		end
		local RayResults = nil
		repeat
			task.wait()
			local rayParams = RaycastParams.new()
			rayParams.FilterType = Enum.RaycastFilterType.Exclude
			rayParams.FilterDescendantsInstances = {Character,Character:GetChildren()}
			RayResults = workspace:Raycast(HumanoidRootPart.Position,Vector3.new(0,-4,0),rayParams)
		until
		RayResults ~= nil
		HumanoidRootPart:FindFirstChild("landing"):Play()
		Humanoid:ChangeState(Enum.HumanoidStateType.GettingUp)
	else
		Animation.AnimationId = PunchTable[math.fmod(PunchCount,#PunchTable)+1]
	end

Clamping each component could lead to a different direction. Clamp the magnitude instead:

-- since you clamp each component to 50, the maximum magnitude would be sqrt(3*50^2) = 86.6
local magnitude = math.clamp(Humanoid.MoveDirection.Magnitude*500, -86.6, 86.6) * 10
local impulse_v3 = Humanoid.MoveDirection.Unit * magnitude
