How do i make trees spawn anywhere in the designated areas?

Help and Feedback Scripting Support
#1

so i have trees and i want to be able to spawn them in random locations but only within boundaries, i will be having multiple of these boundaries too

#2

You’re going to need to use math.random() and use x, y, and x coordinates to make the parameters

I searched it up and found this post: How could I make a part spawn randomly in a given location?

Basically , you just need to do something like this:

local Radius = 10

local x = math.random(0, Radius) 
local y = math.random(0, Radius) 
local z = math.random(0, Radius) 

Part.Position = Vector3.new(x, y, z)

Actually I think this is much better.

local radius = 15 -- The length of the boundary / 2
local boundary1Center = Vector3.new(5,0,9) -- Where you want the center of the boundary to be

while true do 
	task.wait(10) -- Delay for each tree spawning
	local x = math.random(boundary1Center.X - radius, boundary1Center.X + radius)
	local y = boundary1Center.Y
	local z = math.random(boundary1Center.Z - radius, boundary1Center.Z + radius)
	
	local tree = Instance.new("Part", game.Workspace) -- Replace this with tree model
	tree.Name = "Tree"
	tree.Position = Vector3.new(x,y,z)
end

Edit: You could make multiple boundaryCenters and multiple radius’s, up to you!

I made a small typo so I fixed it :slight_smile:

#5

Yeah that is better I just got that code from the post I linked which should help

#6

how do i set this up to place my models randomly?
sorry for late response, ive been modeling the axe and coding it to cut the tree down

#7

Here’s an example, you wanted trees to spawn in a 40x40 area where the center of the boundary is 50, 5, 24.

You would do…

local radius = 20 -- The length of the boundary / 2 because the boundary is 40x40
local boundary1Center = Vector3.new(50,5,24) -- Where you want the center of the boundary to be

while true do 
	task.wait(10) -- Delay for each tree spawning
	local x = math.random(boundary1Center.X - radius, boundary1Center.X + radius)
	local y = boundary1Center.Y
	local z = math.random(boundary1Center.Z - radius, boundary1Center.Z + radius)
	
	local templateTree = game.ReplicatedStorage:FindFirstChild("TreeModel") 
        local tree = templateTree:Clone
        tree.Parent = workspace
        tree.Position = Vector3.new(x,y,z)
	end

If you had multiple boundaries you would just…

  • make a radius2 or radius3
  • make a boundary2Center or boundary3Center
  • either duplicate the while true loop or add it on there, sorry but I can’t do it for you

sorry i forgot to specify i want them to spawn on a part like this:

so i want to place a part, add a script or name it something, then it becomes a “spawn pad” for trees

also can you make sure trees dont spawn inside eachother?

I’m still kinda new to coding so I don’t know how to resolve your 2nd issue, but I can resolve the first.
Do this:

local treeZone = script.Parent -- Parent the script to the tree zone
local center = treeZone.Position -- Since the position is automatically the center, this works great!
local x = treeZone.Size.X
local xRadius = x / 2
local z = treeZone.Size.Z
local zRadius = z / 2
while true do 
	task.wait(10) -- Delay for each tree spawning
	local x = math.random(center.X - xRadius, center.X + xRadius)
	local y = center.Y	
        local z = math.random(center.Z - zRadius, center.Z + zRadius)
	
	local templateTree = game.ReplicatedStorage:FindFirstChild("TreeModel") 
        local tree = templateTree:Clone
        tree.Parent = treeZone -- was previously workspace
        tree.Position = Vector3.new(x,y,z)
	end

Please tell me if you found any bugs with my code!

Also, if you want multiple zones, read my reply for when you asked how to place your models randomly.

OOPS, I meant Pivot, I forgot models don’t have CFrames and Positions.

#13

to get a trees position into a variable, use GetPivot(Tree)
to teleport the tree to another place, use PivotTo(Location)

#14

Im still new to pivoting so if you’re confused you should read documentation im busy rn so i dont have time sry

#15

ok that works, imma make some adjustements to ur code to fit my needs, i just needed the random placement

#16

i made some changes, if you want this is what the script looks like now:

local treeZone = script.Parent -- Parent the script to the tree zone
local center = treeZone.Position -- Since the position is automatically the center, this works great!
local x = treeZone.Size.X
local xRadius = x / 2
local z = treeZone.Size.Z
local zRadius = z / 2
local Spawned = 0
local event = script.Parent.Removed

local function RTree()
	return game.ReplicatedStorage.Trees:GetChildren()[math.random(1, #game.ReplicatedStorage.Trees:GetChildren())]:Clone()
end

event.Event:Connect(function()
	Spawned -= 1
end)

while true do
	task.wait(3) -- Delay for each tree spawning
	if Spawned ~= script.Parent.Max.Value then
		local x = math.random(center.X - xRadius, center.X + xRadius)
		local y = center.Y 
		local z = math.random(center.Z - zRadius, center.Z + zRadius)

		local tree = RTree()
		tree.Parent = treeZone -- was previously workspace
		tree:PivotTo(CFrame.new(x,y,z))
		local TreeOffset = CFrame.Angles(0, math.rad(math.random(1, 360)), 0)
		tree:SetPrimaryPartCFrame(tree:GetPrimaryPartCFrame() * TreeOffset)
		Spawned += 1
	end
end
