Raycast blacklisting

[silver4804]

hey, so i have a really simple gun but it sometimes interferes with the character or the gun. so im wondering how to make like a “blacklist”. (I am terrible when it comes to ray casting)

remote.OnServerEvent:Connect(function(player, position)
	
	local origin = script.Parent.Handle.Part.Position
	local direction = (position - origin).Unit*300
	local result = workspace:Raycast(origin, direction)

	local intersection = result and result.Position or origin + direction
	local distance = (origin - intersection).Magnitude

	local bullet_clone = game.ReplicatedStorage.Assets.Bullet:Clone()
	bullet_clone.Size = Vector3.new(0.1, 0.1, distance)
	bullet_clone.CFrame = CFrame.new(origin, intersection)*CFrame.new(0, 0, -distance/2)
	bullet_clone.Parent = workspace

	if result then
		local part = result.Instance
		local humanoid = part.Parent:FindFirstChild("Humanoid") or part.Parent.Parent:FindFirstChild("Humanoid")

		if humanoid then
			if not character then
				humanoid:TakeDamage(10)
			end	
		end
	end
	for i = 1,10 do
		bullet_clone.Transparency += 0.1
		wait(0.1)
	end

end)

Raycasting accepts three parameters, the origin, the direction, and a RaycastParams object. You are only using the origin and direction.

Here’s an example

local raycastParams = RaycastParams.new()
raycastParams.FilterType = Enum.RaycastFilterType.Blacklist
raycastParams.FilterDescendantsInstances = {whatever u wanna blacklist}

local result = workspace:Raycast(origin, direction, raycastParams)
