Part spinning instead of facing

Help and Feedback Scripting Support

Hi so i am having a problem with a rotation script, Instead of the foot facing where the humanoid root part is facing the part is just spinning around

Heres the spinning script:

hum.Running:Connect(function()
	ProceduralModule:IkLegStep(left_IkTarget, left_RaycastPart, passenger.PrimaryPart, 0.5, 2, 1, 0.05, rayCastParams)
	left_IkTarget.Orientation += Vector3.new(0, root.Orientation.Y, 0)
	task.wait(0.1)

	ProceduralModule:IkLegStep(right_IkTarget, Right_RaycastPart, passenger.PrimaryPart, 0.5, 2, 1, 0.05, rayCastParams)
	ikTargets.Parent.Legs.footR.Orientation += Vector3.new(0, root.Parent.Torso.Orientation.Y, 0)
	task.wait(0.1)
end)

Heres the entire script:

local ProceduralModule = require(game:GetService("ReplicatedStorage").ProceduralModule2)

local runService = game:GetService("RunService")

local passenger = script.Parent
local root = passenger:FindFirstChild("HumanoidRootPart")
local hum = passenger:FindFirstChild("Humanoid")
local alignOrientation = root:FindFirstChild("AlignOrientation")

local target = workspace:FindFirstChild("Target")

--// IkTargets
local ikTargets = passenger:FindFirstChild("IkTargets")
local left_IkTarget = ikTargets:FindFirstChild("LeftTarget")
local right_IkTarget = ikTargets:FindFirstChild("RightTarget")

--// Raycast parts
local raycastParts = passenger:FindFirstChild("RaycastParts")
local left_RaycastPart = raycastParts:FindFirstChild("LeftRaycast")
local Right_RaycastPart = raycastParts:FindFirstChild("RightRaycast")


--// IKControls
local left_IKControl = hum:FindFirstChild("LeftLegIK")
local right_IKControl = hum:FindFirstChild("RightLegIK")

left_IKControl.Pole = root.LeftAtt
right_IKControl.Pole = root.RightAtt

--// RaycastParams
local rayCastParams = RaycastParams.new()
rayCastParams.FilterDescendantsInstances = {passenger}
rayCastParams.FilterType = Enum.RaycastFilterType.Exclude



runService.Heartbeat:Connect(function()
	local rayCast = workspace:Raycast(root.Position, -1000 * root.CFrame.UpVector, rayCastParams)

	if rayCast then
		local rotateToFloorCFrame = ProceduralModule:getRotationBetween(root.CFrame.UpVector, rayCast.Normal)
		local floorOrientedCFrame = rotateToFloorCFrame * CFrame.new(root.Position)

		local dz = (root.Position.Z - target.Position.Z)
		local dx = (root.Position.X - target.Position.X)
		local horizontalAngle = math.atan2(dx, dz)

		alignOrientation.CFrame = floorOrientedCFrame.Rotation * CFrame.fromOrientation(0, horizontalAngle, 0)
	end
end)

hum.Running:Connect(function()
	ProceduralModule:IkLegStep(left_IkTarget, left_RaycastPart, passenger.PrimaryPart, 0.5, 2, 1, 0.05, rayCastParams)
	left_IkTarget.Orientation += Vector3.new(0, root.Orientation.Y, 0)
	task.wait(0.1)

	ProceduralModule:IkLegStep(right_IkTarget, Right_RaycastPart, passenger.PrimaryPart, 0.5, 2, 1, 0.05, rayCastParams)
	ikTargets.Parent.Legs.footR.Orientation += Vector3.new(0, root.Parent.Torso.Orientation.Y, 0)
	task.wait(0.1)
end)

Heres the module script:

-- Author: Roox4



local ProceduralModule = {}


--// Returns a CFrame rotation between two vectors
--// Credit: @EgoMoose (Roblox)
function ProceduralModule:getRotationBetween(u, v)
	local randomAxis = Vector3.new(1, 0, 0)
	
	local dot = u:Dot(v)
	if (dot > 0.99999) then
		return CFrame.new()
		
	elseif (dot < -0.99999) then
		return CFrame.fromAxisAngle(randomAxis, math.pi)
	end
	
	return CFrame.fromAxisAngle(u:Cross(v), math.acos(dot))
end



--[[

Parameters:

ikTarget ->			A reference to the IK target of a leg
ikRayPart ->		A reference to the raycast part of a leg
root ->				The root part of a model
stepDistance ->		A number that specifies a distance a model has to travel before this function executes
stepForward -> 		A number that specifies a length of a step
stepHeight -> 		A number that specifies a maximum height the leg reaches when stepping
stepWait -> 		A number that specifies a how long the step takes (should be a small value like 0.05)
rayCastParams -> 	A reference to the RaycastParams

--]]


--// Calculates the position of a leg
function ProceduralModule:IkLegStep(ikTarget: BasePart, ikRayPart: BasePart, root: BasePart, stepDistance: number, stepForward: number, stepHeight: number, stepWait: number, rayCastParams: RaycastParams)
	stepWait = stepWait or 0.05
	stepForward = stepForward or 0
	stepHeight = stepHeight or 2
	
	local rayCast = workspace:Raycast(ikRayPart.Position, Vector3.new(0, -1000, 0), rayCastParams)
	
	if rayCast then
		if not ikTarget:GetAttribute("PreviousPos") then
			ikTarget:SetAttribute("PreviousPos", Vector3.new(0, 0, 0))
		end
		
		local previousFootPos = ikTarget:GetAttribute("PreviousPos")
		
		local defaultFootPos = rayCast.Position
		local diff = (defaultFootPos - previousFootPos).Magnitude
		
		--// Do a step
		if diff > stepDistance then
			local finalFootPos = rayCast.Position + root.CFrame.LookVector * stepForward
			local middleFootPos = ((finalFootPos - previousFootPos) * 0.5 + previousFootPos) + Vector3.new(0, stepHeight, 0)
			
			coroutine.wrap(function()
				ikTarget.Position = middleFootPos
				task.wait(stepWait)
				ikTarget.Position = finalFootPos
				
				ikTarget:SetAttribute("PreviousPos", ikTarget.Position)
			end)()
		end
	end
end

return ProceduralModule

So why ist it working?

Can you show us a video of the issue? It is hard to understand it like this.

Do you see how the foot is like spinning around its not facing the humanoid root part?

Sorry for delayed reply, I didn’t see that you replied.
Anyways, won’t doing this work?

hum.Running:Connect(function()
	ProceduralModule:IkLegStep(left_IkTarget, left_RaycastPart, passenger.PrimaryPart, 0.5, 2, 1, 0.05, rayCastParams)
	left_IkTarget.Orientation += Vector3.new(0, root.Orientation.Y, 0)
	ikTargets.Parent.Legs.footL.Orientation += Vector3.new(0, root.Parent.Torso.Orientation.Y, 0)
	task.wait(0.1)

	ProceduralModule:IkLegStep(right_IkTarget, Right_RaycastPart, passenger.PrimaryPart, 0.5, 2, 1, 0.05, rayCastParams)
	ikTargets.Parent.Legs.footR.Orientation += Vector3.new(0, root.Parent.Torso.Orientation.Y, 0)
	task.wait(0.1)
end)
