Help with simple Hitbox function

[Crecentez]

I am trying to make a Hitbox class but for some reason the hitbox part is not detecting anything with the :GetTouchingParts()
I have tried doing this witht he Default collision group. does anyone see anything that would cause this to stop working. I am just trying to detect a player/npc

function Hitbox.cast(self: HitboxClass): {BasePart}
	if self.info.shape == "Box" then
		local hitbox: BasePart = Instance.new("Part")
		
		hitbox.Parent = workspace
		hitbox.Name = "Hitbox"
		hitbox.Size = self.info.size
		hitbox.CFrame = self.attatchedTo.CFrame * CFrame.new(self.info.offset)
		hitbox.Orientation = self.attatchedTo.Orientation + self.info.rotation
		hitbox.CanCollide = false
		hitbox.CanQuery = true
		hitbox.CanTouch = true
		hitbox.Anchored = true
		hitbox.CollisionGroup = self.info.collisionGroup
		
		if DEBUG then
			hitbox.Transparency = 0.9
			hitbox.Color = Color3.new(1, 0, 0)
			hitbox.Material = Enum.Material.Neon
		else
			hitbox.Transparency = 1
		end
		
		local parts = hitbox:GetTouchingParts()
		print(hitbox)
		print(parts)
		print(hitbox.CollisionGroup)
		if not DEBUG then hitbox:Destroy() end
		
		return parts
	end
end

GetTouchingParts only works if CanCollide is true, unless you add a TouchInterest. Otherwise it returns an empty list, like you’re seeing.

You can use WorldRoot:GetPartsInPart() instead to avoid the TouchInterest work around.

[Crecentez]

so do both colliding parts need to have CanCollide set to true then?

If the hitbox has no collisions or touch interest, yes.

Or you can just add something like:

local touchInterest = Instance.new("TouchInterest")
touchInterest.Parent = hitbox

Or you can switch GetTouchingParts for Workspace:GetPartsInPart(hitbox), which works for CanCollide = false.
