Hi, I’m making a weather system, with only rain, but I have a big rain part from where the small drops spawn. but Those drops need to be positioned correctly and randomly according to the size of the big rain part, let me know if you know how to do it! I don’t know how to achieve this goal. Thanks

I think he might want to make his own rain system, though.

Well basically u only want to mess with x and z value.

local part = game.Workspace.myPart
local x = part.Size.X / 2
local y = part.Size.Z / 2
while wait(2) do
  local drop = game:GetService("ReplicatedStorage").Raindrop:Clone()
  drop.Parent = game.Workspace
  local rX = math.random(x, -x)
  local rZ = math.random(z, -z)
  drop.CFrame = part.CFrame * CFrame.new(rX, 0, rZ)
end

Thats just my guess tho, I made this code rn on phone and never tested it out

wait. I want the rain drop to be positioned at the size of THE BIG part from where the drops drop

No it didn’t work, what should I do??

#9

Wait but do u actually have, a part in workspace named myPart and a raindrop in replicatedStorage named Raindrop?

I made it my self, like

local x = rainPart.Size.X / 2
local z = rainPart.Size / 2

local rx = math.random(-x , x)
local rz = math.random(-z, x)

rainDrop.CFrame = rainDrop.CFrame * CFrame.new(rx, 0, rz)

I customized your code a bit.

rainDrop.CFrame = rainPart.CFrame * CFrame.new(rx, 0, rz)

oops, didn’t realize it, let me fix it.

#13

uhhh, why is still not working. :slightly_frowning_face:

#14

See it yourself, the rain part is big, but the raindrops aren’t doing well as intended.

#19

Can u show me what u got now? (I mean code)

#20

Sure! Here you go;

local rainPart = workspace.RainPart


local x = rainPart.Size.X / 2
local z = rainPart.Size.Z / 2



while true do
	for i = 1, 10 do
		local prt = Instance.new("Part", workspace)
		prt.Anchored = false
		prt.CanCollide = true
		prt.Name = "Drop"
		prt.Material = "Neon"
		prt.BrickColor = BrickColor.Blue()
		prt.Size = Vector3.new(0.39, 1.2, 0.3)
		local rx = math.random(-x , x)
		local rz = math.random(-z , z)
		
		prt.CFrame = rainPart.CFrame * CFrame.new(rx, 0, rz)
		
		
		wait(0.5)
	end
	wait(0.5)
