Loop spawn brick under feet

Help and Feedback Scripting Support
#1

I’m trying to make a part constantly spawn under my characters feet to stop me from falling so I set the Y value before the loop so that doesn’t change. For some reason the Y value is always set to 0 instead of my position -5. The X and Z loop works as intended

 		local charPos = Player.Character.HumanoidRootPart
		local platform = Instance.new("Part")		
		platform.Color = Color3.fromRGB(255, 0, 0)
		platform.Size = Vector3.new(5,0.2,5)
		platform.Parent = workspace
		platform.Anchored = true
		platform.Position = Vector3.new(nil,charPos.Position.Y - 5,nil)
		while ghostmapEnabled == true do
			task.wait()
			local characterRoot = Player.Character.HumanoidRootPart
			platform.Position = Vector3.new(characterRoot.Position.X,nil,characterRoot.Position.Z)
		end

platform.Position = Vector3.new(characterRoot.Position.X,nil,characterRoot.Position.Z) end
you are literally making it 0 in your script

Thanks for your response! Yeah I realized that after I posted. I was just hoping nil would be set to whatever the Y value was set to before the loop.

I’ve made some changes using CFrames but I can’t figure out how to keep the Y value of the player from changing and to only change the X and Z values in the loop when I move. With these changes I just fall down.

		local charPos = Player.Character.HumanoidRootPart
		local platform = Instance.new("Part")		
		platform.Color = Color3.fromRGB(255, 0, 0)
		platform.Size = Vector3.new(5,0.2,5)
		platform.Anchored = true
		platform.Material = Enum.Material.Neon
		platform.CFrame = CFrame.new(charPos.Position.X,charPos.Position.Y-5,charPos.Position.Z)
		platform.Parent = workspace
		while ghostmapEnabled == true do
			task.wait()
			local charRoot = Player.Character.HumanoidRootPart
			platform.CFrame = charRoot.CFrame * CFrame.new(0,-5,0)
		end

When you create a new Vector3, or any other value type using .new, the method has no way of knowing what the previous value was. Try this instead:

local platform = Instance.new("Part")		
platform.Color = Color3.fromRGB(255, 0, 0)
platform.Size = Vector3.new(5,0.2,5)
platform.Anchored = true
platform.Material = Enum.Material.Neon

game:GetService("RunService").RenderStepped:Connect(function()
    if ghostmapEnabled and Player.Character and Player.Character:FindFirstChild("HumanoidRootPart") then
        local root = Player.Character.HumanoidRootPart
        platform.CFrame = root.CFrame * CFrame.new(0,-4 - platform.Size.Y / 2,0)
        if not platform.Parent then platform.Parent = workspace end
    end
end)

Thanks for your quick response! I gave your edits a shot but now my character slowly falls down at a decent pace. Is there any way to spawn the brick under the character then have the loop only update the X and Z positional values?

local platform = Instance.new("Part")		
platform.Color = Color3.fromRGB(255, 0, 0)
platform.Size = Vector3.new(5,0.2,5)
platform.Anchored = true
platform.Material = Enum.Material.Neon

local ypos = 0
game:GetService("RunService").RenderStepped:Connect(function()
    if ghostmapEnabled and Player.Character and Player.Character:FindFirstChild("HumanoidRootPart") then
        local root = Player.Character.HumanoidRootPart
        platform.Position = Vector3.new(root.Position.X, ypos, root.Position.Z)
        if not platform.Parent then platform.Parent = workspace end
    end
end)

This just sets the parts Y value to 0 instead of Y value of the character - 3

Physics is hard sometimes. If you set the position to always under the character, the character will likely fall slowly unless you’re smart with how you code it. I don’t really know how to fix that right now.

I figured it out by doing:

platform.CFrame = CFrame.new(charPos.CFrame.X, platform.CFrame.Y, charPos.CFrame.Z)

local function GhostMapFunc()
	local platform = Instance.new("Part")	
	if ghostmapEnabled then
		for _, map in pairs(game.Workspace:GetChildren()) do
			if map:IsA("Part") or map:IsA("Model") and not map:FindFirstChild("Humanoid") then
				map.Parent = game.Lighting
			end
		end
		local charPos = Player.Character.HumanoidRootPart
		platform.Color = Color3.fromRGB(255, 0, 0)
		platform.Size = Vector3.new(5,0.2,5)
		platform.Anchored = true
		platform.Material = Enum.Material.Neon
		platform.CFrame = charPos.CFrame * CFrame.new(0, -4, 0)
		platform.Parent = workspace
		while ghostmapEnabled == true do
			task.wait()
			local charRoot = Player.Character:WaitForChild("HumanoidRootPart")
			platform.CFrame = CFrame.new(charPos.CFrame.X, platform.CFrame.Y, charPos.CFrame.Z)
		end
	elseif not ghostmapEnabled then
		for _, map in pairs(game.Lighting:GetChildren()) do
			if map:IsA("Part") or map:IsA("Model") and not map:FindFirstChild("Humanoid") then
				map.Parent = game.Workspace
			end
		end
		platform:Destroy()
	end
end

Thank you so much for your help!
