Tree Generator Module

[Chest_games (Pedro)]

Sooo, this is my first time posting a topic , and i wanted to show my new Module, the tree generator module, i made this one because i wanted to try something new, and i always liked the way trees in Lumber Tycoon 2 grow, so i decided to remake it for learning purposes, it was my first time using so much CFrame so it was pretty hard to deal with displacement, but with some help i got to make it work, it’s looking like this in the moment:

Sakuras

What about making them tinier?

Tinier Sakuras

Or maybe some Namek like trees with an exagerated amount of Brunches?

Blue Tree

Autumn Tree

Added some color variation, thanks to @koziahss for the tip

Autumn CV

Random Tree

Some Graphics

I’ll be uploading more examples as i update the module
Well, really liked the way it turned out, this is my Module, if you guys know any way of improving it, please tell me, i’ll comment everything as soon as possible:

--- TreeModule Create by @Chest_games, if your interested in my work and want to contact me, just hit me on my discord Pedraunzin#0411, i'll answer any question asap. Thank you for using my Module!!

local TreeModule = {}

--- Contructors for better performance
local CFramenew = CFrame.new

I think you have done s great job with that.

A couple of miniscule optimizations though:

There is a new Random object that is basically the “better” way of getting random numbers. I don’t know if or why it is true but maybe you might want to consider using it for future code.

When instancing a objects it is recommended to not use the second parameter of Instance.new due to its slowness. It actually more performant to parents to the workspace at the very end. If you were to use this as a method for trees in-game you might hit lag spikes if there is a lot of instancing too.

Finally, might just be me but usually I like to store all the Constructors in a variable. I don’t remember where I heard this but doing it is faster than indexing.

local CFramenew = CFrame.new
for I = 1, 1000 do
    local MyCF = CFramenew()
end
-- Is faster than
for I = 1, 1000 do
    local MyCF = CFrame.new()
end

I think in term of visuals you might want to add a little colour variation to the leaves. Some lighter some darker.

But I think your work is pretty good. well done.

Thank you for replying, i didn’t know about the parenting stuff, thank you for that too, i’ll look at the code and see if i can optimize it a little, i thought of the lag when instancing objects, but i believe that it will not be a problem, cuz the original purpose of the module is to grow trees slowly, i’ll change the speed in the module asap, i’ll also update my script to work with the constructors thing, if it’ll run smoother, because my stress tests made my game go way slower than i imagined.

[Franklin_Surten (Franklin)]

This looks amazing good job. And my question is, is it growing on real time or in roblox time. If it’s growing on real time then this is amazing job.

[Chest_games (Pedro)]

I made it to grow in roblox time, but i think i can try to do something with this idea, thank you for the feedback!

[koziahss (Agent_Invalid)]

Sorry I forgot there is one more thing too. There is a new and improved library that you might want to look at

task.defer instead of spawn

Task Library - Now Available!

Hey developers, We have just enabled a brand new library that you can use in your projects. The task library allows you to talk directly with our engine’s task scheduler to manage and schedule code. It features a number of new methods as well as some improvements to existing methods. Details task.spawn Takes a thread or function and resumes it immediately through the engine’s scheduler. Additional arguments are passed to the thread or function being resumed. void task.spawn(function | thread,…

Yeah sorry I forgot to link a resource on the parenting parameter for Instance.new
Here it is:

PSA: Don't use Instance.new() with parent argument

I’ve discovered a pretty bad performance issue in one of top games that has to do with Instance.new and wanted to write about this, since this is not obvious unless you know the system inside out. Tthere are several ways to create a ROBLOX object in Lua: local obj = Instance.new(‘type’); fill obj fields local obj = Instance.new(‘type’, parent); fill obj fields local obj = util.Create(‘type’, { field1 = value1, … }) If you care at all about performance, please only use the first option - I wi…

Happy coding

[Chest_games (Pedro)]

Thanks about the links, it’ll help a lot in future code, i tried using the task.defer, but it seems like it schedule it to happen a little after the code is called, and i need it to run just in the right moment so it didn’t work that well, but still thanks for your time!

[lilsquish08]

Hey, so sorry for bumping but could I get an example of how to use it? I can’t figure it out!

treeModule.TreeGrowth({tree},4,10,2,“Pine Cone”,“Sea Green”)

this is what i did u can tween it if u want
