CFrames for dash system not combining properly

Help and Feedback Scripting Support
#1

Took a dash system from someone else on the DevForum, for some reason instead of the position becoming the humanoids root part combined with the DashRange it instead sets the position has 0,0,0 on the workspace, am i missing a piece of code?

local uis = game:GetService("UserInputService")
local plr = game:GetService("Players").LocalPlayer
local chr = plr.Character or plr.CharacterAdded:Wait()
local humRoot = chr:WaitForChild("HumanoidRootPart")

local DashRange = 200
local DashCD = 3
local CanDash = false


--The Dash itself
function Dash(humRoot,direction)
		
		--Setting Directional Dashes
		local position;
		if direction == 'forward' then
			position = (humRoot.CFrame*CFrame.new(0,0,DashRange)).p
		elseif direction == 'backward' then
			position = (humRoot.CFrame*CFrame.new(0,0,-DashRange))
		end
		
		local i = Instance.new('BodyPosition')
		i.MaxForce = Vector3.new(1000000,5,1000000)
		i.P = 100000
		i.D = 2000
		
	i.Parent = humRoot
		coroutine.wrap(function()
			wait(0.5)
			i:Destroy()
		end)()
	end

is that the full script? Because you didnt use the uis variable(i think)

uis.InputBegan:Connect(function(Input)
	print(Input.KeyCode)
	
	Dash()
end)

It looks like you didn’t actually set the Position property of the BodyPosition to the position variable you’ve made.

To do that, simply add i.Position = position after you created the BodyPosition.

Not the full script, only showed parts that were possibly included in the bug, if you’re interested the main test script looks like this

local tool = script.Parent
local uis = game:GetService("UserInputService")
local plr = game:GetService("Players").LocalPlayer
local chr = plr.Character or plr.CharacterAdded:Wait()
local humRoot = chr:WaitForChild("HumanoidRootPart")

local DashRange = 200
local DashCD = 3
local CanDash = false


--The Dash itself
function Dash(humRoot,direction)
		
		--Setting Directional Dashes
		local position;
		if direction == 'forward' then
			position = (humRoot.CFrame*CFrame.new(0,0,DashRange))
		elseif direction == 'backward' then
			position = (humRoot.CFrame*CFrame.new(0,0,-DashRange))
		end
		
		local i = Instance.new('BodyPosition')
		i.MaxForce = Vector3.new(1000000,5,1000000)
		i.P = 100000
		i.D = 2000
	
	i.Parent = humRoot
		coroutine.wrap(function()
			wait(0.5)
			i:Destroy()
		end)()
	end


tool.Equipped:Connect(function()
	print("tool equipt")
	--Sticks and Glue
	uis.InputBegan:Connect(function(input,istyping)
		if istyping then return end
		if input.KeyCode == Enum.KeyCode.R and uis:IsKeyDown(Enum.KeyCode.W) then
			if CanDash == true then
				CanDash = false
				Dash(humRoot,'forward')
				print("Dashed forward")
			else
				CanDash = true
				coroutine.wrap(function()
					wait(DashCD)
					CanDash = false
				end)()						
			end
		elseif input.KeyCode == Enum.KeyCode.R and uis:IsKeyDown(Enum.KeyCode.S) then
			if CanDash == true then
				CanDash = false
				Dash(humRoot,'backward')
				print("dashed backweards")
			else
				CanDash = true
				coroutine.wrap(function()
					wait(DashCD)
					CanDash = false
				end)()
			end
			
			
		end
	end)
	
	
end)

Tried both i.Position and i.CFrame.
i.Position = position gives me the error
Unable to assign property Position. Vector3 expected, got CFrame
i.CFrame = position gives me the error
CFrame is not a valid member of BodyPosition "BodyPosition"

I forgot to mention that you need to use the Position property from the CFrame only, so it should be i.Position = position.P instead.

Ah, I somehow did not notice that… Thanks for your help!
