How to Make Lightning

Help and Feedback Scripting Support
#1

How do I script Lightning I saw some old posts on it but they never gave a really good script on how to do it, only the logic. I’m not very good at scripting so Idk how to do it. Can someone help?

You could use math.random to randomize the position. Then use Raycasting to create the part.

You can view this tutorial, and modify the script as you wish.
I don’t know if that, or something like that.

That won does not give the script :confused: RIP

How would I do that? I’m trying to make it “jump” between 2 parts

Wdym? It should give you the script its a tutorial, do you mean to copy and paste?

Yeah because I’m a slow typer :confused: welp

do you know how to make this script go from one part to another instead of just vertical?

local serv = game.ReplicatedStorage

function CastLightningDown(head) -- vector3 start position

	local maxRange = 5 -- how far in polar coordinates can the lightning go
	local heightOffset = 5 -- how far the 3D vector is offset

	local boltParts = {}

	while head.Y > 0 do -- the advantage of using a Vector3 as the end of the lightning bolt
		local angle = math.pi*4*math.random() -- 4 because I don't trust the random distribution
		local radius = math.random()*maxRange -- radius

		local dir = Vector3.new(math.cos(angle)*radius,-heightOffset,-math.sin(angle)*radius) -- converting the XY plane of a graph into the XZ plane of a part requires Z to be negative

		local newPart = serv.Lightning:Clone()
		newPart.Size = Vector3.new(.1,.1,math.random(1,5)) -- component change to take advantage of CFrame's 2-vector construction method
		newPart.CFrame = CFrame.new(head,head+dir)*CFrame.new(0,0,-newPart.Size.Z/2) -- starting point, target point, and offset by half the length
		table.insert(boltParts,newPart)
		head = newPart.CFrame*Vector3.new(0,0,-newPart.Size.Z/2) -- move the head to the end of the part so we can continuously cast bolts
		newPart.Parent = workspace	
	end

end
while true do
	for i = 1, 5 do -- make 30 lightning bolts
		CastLightningDown(Vector3.new(0,100,0))
	end
	wait(.1)
	local children = workspace:GetChildren()
	for i, child in ipairs(children) do
		if child.Name == "Lightning" then
			child:Destroy()
		end
	end
end

change each part of the script, and see what they do

I said you could use Raycasting to send an invisible ray to that part, then create a part out of it.

Here’s a developer page for Raycasting if you need it.
