How do I get Parts to Spawn in an Area Randomly?

Help and Feedback Scripting Support

#1

Basically I want it kinda like Pet Sim99/Pet SimX Has it where it drops coins randomly, and stops when theres already a lot of coins.

The issue is, that im not sure how I can have the part spawn in an area. I know It’s something like with math.random() something like that but Im still unsure.

Iv’e tried looking on the web, solutions on the dev forum, videos, but nothing. Im not new to scripting, but Im new to spawning stuff.

I also want it to sort of spawn in the air so I can tween a bounce to the ground, which I don’t know if that will be hard or not.

Thank You!

If you would like to place a part in a random spot, simply use math.random():

local rand_x = math.random(-10, 10)
local rand_z = math.random(-10, 10)

local part = game.ServerStorage.Part:Clone()
part.Position = Vector3.new(rand_x, 5, rand_z)
part.parent = workspace

This chooses random x and z coordinates from -10 to 10 and places a cloned part at that position in the workspace at a y value of 5.

A code for randomly throwing ores over a wide terrain based on a certain ratio. I usually do such things with AI, hope it helps you.

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Workspace = game:GetService("Workspace")

local mine = ReplicatedStorage:FindFirstChild("Mine") -- "Mine" objesini kontrol et

-- Settings klasöründen maden bulunabilirlik oranını okuma
local settingsFolder = script.Parent:WaitForChild("Settings")  -- Ayarları içeren klasör
local mineralAvailability = settingsFolder:WaitForChild("MineralAvailability")  -- "MineralAvailability" isimli IntValue
local mineralAvailabilityRate = 1 + (mineralAvailability.Value / 2)  -- 1 ile 10 arasında bir değer

local minesFolder = ReplicatedStorage:WaitForChild("Mines")  -- Ayarları içeren klasör

local miningData = {
	["Iron"] = 25,
	["Copper"] = 15,
	["Silver"] = 12,
	["Gold"] = 8,
	["Diamond"] = 3,
	["Titanium"] = 1,
	["Uranium"] = 1,
}

local spawnCount = 10
local spawnAreas = {script.Parent}

				return result.Position + Vector3.new(0, 1, 0) -- Madenin yere batmaması için biraz yukarıda olmasını sağlayalım

You can keep track of how many coins have spawned in a script and decide whether to spawn more based on the number.

#5

This script should give you a baseline.

local area = regionhere -- a part
local ySpawnLevel = 20 -- gets added

function getPosition()
	local randX, randZ = Random.new():NextNumber(-area.Size.X/2, area.Size.X/2), Random.new():NextNumber(-area.Size.Z/2, area.Size.Z/2)
	local finalPos = area.Position + Vector3.new(randX, ySpawnLevel, randZ)
	return finalPos
end

If you want to do a tween, you can get the landed poisiton by doing -= vector3.new(0, ySpawnLevel, 0)

#6

Where should I place that script?

#8

Im pretty sure it should be placed in serverScriptservice

#9

I figured that I just reworked the system. Instead of random spawning, I did something else. Thank you all for helping!
