Newcomer here! Trying to figure out how to access scripts in another object from a script

[rapid cave]

Hello all! So as the title suggests, I am extremely new to Roblox Studio, and am coming here after having plenty of experience in Unity. Now what I'm trying to do is access the script of one object from another. For example:

Say the game has a script that stores amount of Wood a player has, let's call this PlayerWood. Trees spawn randomly around the map, each with a script detailing how much food the tree is worth and performs the chopping action, let's call this TreeWorth. The player walks over to a tree and chops it down. From the TreeWorth script, how can I access the PlayerWood script in order to increase the player's wood?

In Unity, this would be done by retrieving the script from the object itself. How would this kind of thing work in Roblox Studio? Any help is appreciated!

you can use ModuleScripts

[marble cape]

Shouldn't the playerwood be a value?

Just change it in the treeworth script

[rapid cave]

I'm assuming playerwood would be in some separate script, like one to keep track of "Resources" or something

[marble cape]

Oh I see

[jagged shadow]

however, you dont need to use a script inside, but in your example, imagine you have your playerwood script

-- Player Wood
[Define player]

local function TreeChoped(tree)
  local moduleScript = assert(tree:FindFirstChildOfClass("ModuleScript"), "No module")
  local success, module = pcall(function() require(moduleScript) end)
  assert(success, `Cant require {moduleScript.Name}`)
  player.Wood.Value += module.WoodNumber
end

[OnTreeChoped]:Connect(TreeChoped)

and then the module script that looks like

-- WoodScript (in your tree)

local TreeValues = {
  WoodNumber = 10
}

return TreeValues

but what you can do is somply create a NumberValue in your tree

Why ?

because the value can me editeds, so for example the tree a will give 10 woods, but the tree b will only give you 8

You forgot to call require 👀

[jagged shadow]

however, with module scripts, its the same for all, so you wont really need to create an instance for all, and you can just create 1 screip

[jagged shadow]

:(

[jagged shadow]

here you go @tropic zephyr

happy ?

no but outside the joke he is right

my bad i forgot to require the module script

tell me if you dont really understand @rapid cave

[rapid cave]

I think I kind of understand. You mentioned I could change the tree value using the module script. How would I go about that in, hypothetically, a script that spawns trees around a map. Say I want to spawn one tree with value 6 and one with value 8?

[jagged shadow]

well i knida said the opposite @rapid cave

basically, you cant really edit the module script

once its here, its here and its the same for all

howveer, if its number value as i mentionned, you can easily edit the values

so for example you have 2 trees

local treeA = treeModel:Clone()
local treeB = treeModel:Clone()

what you can do is cloning your module script

local treeA = treeModel:Clone()
moduleScript:Clone().Parent = treeA
local treeB = treeModel:Clone()
moduleScript:Clone().Parent = treeB

but its kindof pointless since its the same for all, so you can just require the original and not the one in each tree

however with a NumberValue, its different

you can set the value that you want in it

[rapid cave]

What's NumberValue?

[jagged shadow]

basically, its an instance that holds a number

but you can do better by using attributes

basically, it doesnt create an instance, its just attribute a new custom property to the object

[rapid cave]

Oh I didn't even know that was a thing! In that case, say if each tree had an Attribute ("woodnum"), would I access that using something along the lines of

local treeA = treeModel:Clone()
local treeWood = treeA.Properties.woodnum

[jagged shadow]

haha nice try

but its pretty much like that yea

you can read this doc if you wanna learn more https://create.roblox.com/docs/studio/instance-attributes

but basically it works like that

local treeA = treeModel:Clone()
weapon:SetAttribute("WoodDrop", 6)

[marble cape]

^^ good luck w that

[jagged shadow]

then replace this script by

-- Player Wood
[Define player]

local function TreeChoped(tree)
  local val = assert(tree:GetAttribute("WoodDrop"), "No wood drop :(")
  player.Wood.Value += val
end

[OnTreeChoped]:Connect(TreeChoped)

so its wayyyy simplier

basically you can set attribute to a value with SetAttribute

and then querry it with GetAttribute

its not complucated at all

[jagged shadow]

you dont even need luck lol

[marble cape]

Dawg

Aight

[rapid cave]

Ty for your help!!!

[strong goblet]

** You are now Level 1! **

[rapid cave]

If it's okay I do have one more question lol

[jagged shadow]

go on

[marble cape]

[jagged shadow]

im gonna sleep but ill awner on phone

[rapid cave]

Say you can chop the tree just by clicking on it, simple. Is it possible to trigger TreeChopped(tree) from the script that detects the mouse over the tree + input, or should that be in the same script as TreeChopped()?

Sorry if that's confusing I'm just tryna understand script/object-to-script/object access here

[jagged shadow]

You can use biandable events for that

But it's your choice

You can simply have everything in a script, or having different script

[rapid cave]

Oh god I have no clue what that is so I have some googling to do

[jagged shadow]

That's my opinion, you can also here what @marble cape have to say

[marble cape]

I mean, I ain't that familiar with this topic

[jagged shadow]

It really depends on what you want to do

You can search for click detectors if you just want to click on the tree to chop it

Or tools if you wanna use tools like axe in terraria or minecraft

Or press e to chop

[marble cape]

Yes, click detectors should work just fine

Or prox-

[jagged shadow]

You can see proximity prompts,

[marble cape]

Yes, what he said

[jagged shadow]

Yes
