So I’m trying to make the beam position correctly with his eyes and make the head and the beam rotate where the camera is looking. I’m not really good a scripting so this is the code I have.
--||Service||--
local Runservice = game:GetService("RunService")
local UserInput = game:GetService("UserInputService")
local RS = game:GetService("ReplicatedStorage")
--||Variables||--
local Tool = script.Parent
local Beam = RS.BEAMPART
local Debounce = true
local flare1 = Tool.Handle.Flare1
local flare2 = Tool.Handle.Flare2
Tool.Equipped:Connect(function()
flare1.Parent = Tool.Parent:FindFirstChild("Head")
flare2.Parent = Tool.Parent:FindFirstChild("Head")
flare1:Emit(5)
flare2:Emit(5)
end)
Tool.Activated:Connect(function()
if Debounce then
Debounce = false
print(Tool.Parent.Name)
Beam.Parent = workspace
Beam.Position = Tool.Parent["Head"].Position + CFrame.new(0,0,15)
Beam:Clone()
task.wait(1)
Debounce = true
end
end)
if not Debounce then
Runservice.RenderStepped:Connect(function()
local head = Tool.Parent:FindFirstChild("Head")
local camera = workspace.CurrentCamera
head.Position = camera.CFrame:toObjectSpace(camera.CFrame).lookVector
end)
end
You cannot add a cframe to a vector; you can, however, add a vector to a cframe (I think).
So if we go off of the picture you gave, we can do something like this:
local head = char.Head or char:WaitForChild("Head")
local beam = "beam_here"
local beam_length = 5
local dir = head.CFrame.LookVector
local pos = head.CFrame.p
local cf = CFrame.new(pos, dir)
beam.Position = (cf * CFrame.new(0, 0, -beam_length)).p
-- the "p" is something you can do with CFrame's and is just a shorter way of typing CFrame.Position
-- this is just a theory I haven't tested this in studio so it might not work.
local dir = head.CFrame.LookVector
local pos = head.CFrame.p
local cf = CFrame.lookAlong(pos, dir)
And don’t forget to divide beam_length by 2
Other than that it looks interesting. Another problem is you would probably want the rotation as well as the position right?
I have no clue what lookAlong does, but if you look at CFrame.new(), you can either do CFrame.new(x, y, z) – positions or CFrame.new(pos, dir) – pos vector3 as the first value and dir vector3 as the second value. And no, you won’t divide beam_length by 2 or anything like that.
This was mainly just an example, but to answer your question, if you were trying to make it point in the direction of the head once, then no, but if you were trying to make it point in the direction of the head at all times, then yes, you would need one, and this would be the only part you need in the loop:
local dir = head.CFrame.LookVector
local pos = head.CFrame.p
local cf = CFrame.new(pos, dir)
beam.Position = (cf * CFrame.new(0, 0, -beam_length)).p
I think you should just create a Weld inside BEAMPART. Then just change the weld property Part0 to head and Part1 to BEAMPART via script inside the Activated function. Then you can just edit the C0 or C1 property of the weld (in studio) to get it to how you want it.
So this is the weld idea I had. You can create one inside the beampart and then create a rig and set Part1 to the BEAMPART and Part0 to the Rig’s Head. This is so you can change the C0 property until it looks something like this or however you want it. Then just set Part1 and Part0 to nil, or simply delete the rig you created. Now all you would need to do then is set Part1 and Part0 of the weld when the beam is activated.

local flare1 = Tool.Handle.Flare1
local flare2 = Tool.Handle.Flare2
Tool.Equipped:Connect(function()
flare1.Parent = Tool.Parent:FindFirstChild("Head")
flare2.Parent = Tool.Parent:FindFirstChild("Head")
flare1:Emit(5)
flare2:Emit(5)
end)
Tool.Activated:Connect(function()
if Debounce then
Debounce = false
print(Tool.Parent.Name)
Beam.Parent = workspace
Beam:Clone()
Beam.Weld.C0 = char:WaitForChild("Head")
Beam.Weld.C1 = Beam
task.wait(1)
Beam.Weld.C0 = nil
Beam.Weld.C1 = nil
Debounce = true
end
end)
if Debounce then
local head = char.Head or char:WaitForChild("Head")
local beam = "beam_here"
local beam_length = 5
local dir = head.CFrame.LookVector
local pos = head.CFrame.p
local cf = CFrame.lookAlong(pos, dir)
Beam.Position = (cf * CFrame.new(0, 0, -beam_length)).p
end
I think the only consistent way to keep it from spawning there is by keeping the BEAMPART outside of workspace. Like in ReplicatedStorage, for example.
