Part not being properly created whilst freefalling

[mrkimitsu]

In order to recreate the jump-attack from the Sonic franchise (preferably the Classic era), I had thought of creating a Hitbox part whilst the player is an aerial state. Here’s some semi-pseudocode to get an idea of my original thought process. whilst programming.

Humanoid.FreeFalling:Connect(function(ACTIVE)
	if ACTIVE then
		local PART = Instance.new("Part")
		PART.Touched:Connect(function(HIT)
			if HIT.Parent:FindFirstChild("Humanoid") then
				local EM_HUMANOID = HIT.Parent.Humanoid
				EM_HUMANOID:TakeDamage(100)
			end
		end)
	else
		PART:Destroy()
	end
end)

I’m not sure if I can really explain what the issue is since even I am confused by the footage. It seems that whilst freefalling, the player gets anchored for a bit and then teleports back to the baseplate.

Here is a file of the current workspace…
Jump_Attack.rbxl (101.0 KB)

Have you tried setting up print statements to see if your code is running?

You need to parent any newly created parts to something, in this case workspace ( or some descendant of workspace).

You’ll also need to weld it / anchor it / move it about and stuff in order to get it to be where you want

The Hitbox Part is parented to something

			if ACTIVE then
				local HITBOX_PART			= Instance.new("Part")
				HITBOX_PART.Color			= Color3.new(1, 0, 0)
				HITBOX_PART.Transparency	= 0.5
				HITBOX_PART.Name			= "Hitbox"
				HITBOX_PART.Parent			= CHARACTER
				HITBOX_PART.Size			= Vector3.new(6, 7, 5)
				HITBOX_PART.Position		= HUMANOIDROOTPART.Position
				HITBOX_PART.CanCollide		= false
				HITBOX_PART.Anchored		= true

				local HITBOX_WELD			= Instance.new("ManualWeld")
				HITBOX_WELD.Part0			= HITBOX_PART
				HITBOX_WELD.Part1			= HUMANOIDROOTPART
				HITBOX_WELD.C0				= HITBOX_WELD.Part0.CFrame:ToObjectSpace(HITBOX_WELD.Part1.CFrame)
				HITBOX_WELD.Parent			= HITBOX_WELD.Part0
				print("Active")
			else
				if CHARACTER:FindFirstChild("Hitbox") then
					local HITBOX_PART		= CHARACTER.Hitbox
					HITBOX_PART:Destroy()
				end
			end

Okay, I believe that I’ve managed to resolve this. It could be that HITBOX_PART’s size is too large.
