Following parts are jittering

[z_yd]

What do you want to achieve?
Hello, I created a script that makes the parts go towards the position of the mouse and I made it so the parts won’t try to stack using raycast and region3. I still don’t know much about a lot of stuff and I am just messing around with the stuff in my script. Anyways, I want the parts to not jitter or try to push other parts to get to the given position, how do I fix this? I’m trying to achieve the Movement System in Cube Eat Cube created by stickmasterluke.

This is what mine looks like -

This is Cube Eat Cube’s movement system -

This is the script -

local Workspace = game:GetService("Workspace")
local Players = game:GetService("Players")

local speed = 10
local mouse = Players.LocalPlayer:GetMouse()

local function bodyPosGyro(part)
	local bodyPosition = Instance.new("BodyPosition")
	bodyPosition.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
	--bodyPosition.D = 5000
	--bodyPosition.P = 5000
	bodyPosition.Parent = part
	
	local bodyGyro = Instance.new("BodyGyro")
	bodyGyro.MaxTorque = Vector3.new(math.huge, math.huge, math.huge)
	bodyGyro.P = 1000000
	bodyGyro.D = 1000000
	bodyGyro.CFrame = CFrame.new(part.Position)
	bodyGyro.Parent = part
end

game:GetService("RunService").RenderStepped:Connect(function()
	for _, part in pairs(workspace:WaitForChild("Folder"):GetChildren()) do
		if part:IsA("BasePart") and part.Name == "Part" then
			if not part:FindFirstChild("BodyPosition") and not part:FindFirstChild("BodyGyro") then
				bodyPosGyro(part)
			end
			
			mouse.TargetFilter = part.Parent
			local targetPosition = mouse.Hit.Position
			
			local ray = Ray.new(part.Position, Vector3.new(0, -1, 0) * 10)
			local hitPart, hitPosition = workspace:FindPartOnRay(ray, part.Parent)
			
			local currentPosition = part.Position
			local direction = Vector3.new(targetPosition.x - currentPosition.x, 0, targetPosition.z - currentPosition.z).unit
			local newPosition = currentPosition + direction * speed
				
			if part then
				local regionSize = part.Size + Vector3.new(0.1,0.1,0.1)
				local region = Region3.new(part.Position - regionSize/2, part.Position + regionSize/2)
				
				--[[local rV = Instance.new("Part")
				rV.Name = "rV"
				rV.Anchored = true
				rV.CanCollide = false
				rV.Transparency = 0.5
				rV.Size = region.Size
				rV.CFrame = region.CFrame
				rV.Parent = workspace]]
				
				local collisions = workspace:FindPartsInRegion3(region, part)
				for _, collisionPart in pairs(collisions) do
					if collisionPart:IsA("BasePart") and collisionPart.Name == "Part" and collisionPart ~= part then
						local separationDirection = (part.Position - collisionPart.Position).unit
						newPosition = part.Position + separationDirection * speed
					end
				end
			end
			
			if hitPart then
				newPosition = Vector3.new(newPosition.x, hitPosition.y, newPosition.z)
			end
			
			part:WaitForChild("BodyPosition").Position = newPosition
			part:WaitForChild("BodyGyro").CFrame = CFrame.new(Vector3.new(part.Position.x, part.Position.y, part.Position.z))

			local distance = (targetPosition - part.Position).magnitude
			if distance < 1.5 then
				part:WaitForChild("BodyPosition").Position = targetPosition
				if hitPart then
					targetPosition = hitPosition
				end
			end
		end
	end
end)

game.ReplicatedStorage.Part:FireServer()

go to the physics properties of the parts and set the custom physical properties to true, reduce their bounciness there. If you are doing it in code there should be a part.bounciness or something similar.

Unfortunately it didnt work, I tried removing region3 in my script and it reduced the jittering significantly but I need it to prevent parts from stacking. Reducing speed didn’t really work either.

[Verse_NOVA (NOVA)]

it might be this code

for _, collisionPart in pairs(collisions) do
					if collisionPart:IsA("BasePart") and collisionPart.Name == "Part" and collisionPart ~= part then
						local separationDirection = (part.Position - collisionPart.Position).unit
						newPosition = part.Position + separationDirection * speed
					end
				end

indents are screwed up idk why, anyway
adding a collision will make a part “jitter”. comment out the 4th line and see what happens.

I ended up just removing region3, i tried raycasting in all sides and it almost worked but it just wont move the parts anymore once its stopped. The player’s will always be moving anyways plus the jittering is significantly reduced with this. Thanks!
