How can I make it so that a raycast can shoot directly forward?

[StarJ3M]

I’m making a wall hopping system in my game, and I’m not that experienced with ray cast. I’m trying to figure out how to shoot a ray directly forward from the humanoids root part, should I use CFrame.LookVector?

local char = game.Players.LocalPlayer.Character or game.Players.LocalPlayer.CharacterAdded:Wait()
local humanoid = char:WaitForChild("Humanoid")
local root = char.PrimaryPart

local origion = root.Position
local direction = origion.Unit * Vector3.new(2, 2, 5)

local part = Instance.new("Part", workspace)
part.Anchored = true
part.Position = origion
part.Size = direction
part.CanCollide = false

while task.wait() do
	origion = root.Position
	
	part.Position = origion
	part.Size = direction
	local forwardRay = workspace:Raycast(origion, direction)
	
	part.Position = origion
	part.Size = direction
	
	if forwardRay then
		print(forwardRay.Instance)
	end
end

I suggest instead of while task.wait() do, you use RunService, it runs every frame.
Plus HumanoidRootPart.CFrame.LookVector would work in fact, you’re correct there!

Ok so, I’m having issues with the raycast now…
