ACCESSING FUNCTION FROM ANOTHER SCRIPT(GODOT) | Godot Café | Page 1

#

Is there a way to trigger the change_difficulty(a function from another script)? with my difficulty button?

#

This is what I tried

#

Signals are the proper way, if you want to call it directly you need reference to the player NODE. Currently you're trying to get the node from the FileSystem, this isn't going to work. You will need to get the node from the SCENE.

timid marten Feb 23, 2023, 1:24 PM

#

Can you help me? The tutorial about signals you sent earlier I find it not relatable to my problem as he is working with signals in the same node

rigid phoenix Feb 23, 2023, 1:24 PM

#

Send me a screenshot of your scene

timid marten Feb 23, 2023, 1:26 PM

#

this is the one i need to access

#

and this is the button i will use to trigger the method

rigid phoenix Feb 23, 2023, 1:28 PM

#

And does SelectDifficulty load as default?

timid marten Feb 23, 2023, 1:28 PM

#

yes

#

error shows when i click any of the buttons

#

#

rigid phoenix Feb 23, 2023, 1:29 PM

#

Yes because you're not getting the player node correctly, one second.

#

Based on how you have this setup, you could create the player as an Autoload. That way it's always loaded no matter how you change your level

timid marten Feb 23, 2023, 1:31 PM

#

how can I do that?

#

my player is almost the main code for the game

rigid phoenix Feb 23, 2023, 1:32 PM

#

Go Project > Project Settings > Autoload. Select the path to your player SCENE, set the Node Name to Player then click Add

#

Now your Player scene will be loaded before everything else and will retain for the length of the game

#

#

Should look like this

#

well along those lines anyway

timid marten Feb 23, 2023, 1:33 PM

#

done

#

but

rigid phoenix Feb 23, 2023, 1:33 PM

#

Now

timid marten Feb 23, 2023, 1:33 PM

#

now I cant run the whole code

rigid phoenix Feb 23, 2023, 1:33 PM

#

to call the function

timid marten Feb 23, 2023, 1:33 PM

#

rigid phoenix Feb 23, 2023, 1:33 PM

#

oh remove class_name

#

you set that with the autoload

#

class_name doesn't matter in this instance and Player SHOULD only be created once

timid marten Feb 23, 2023, 1:34 PM

#

rigid phoenix Feb 23, 2023, 1:34 PM

#

It's based off the Singleton programming pattern but it's not exactly true to it. So whilst you can create more than one at runtime, I HIGHLY ADVISE NOT TO.

timid marten Feb 23, 2023, 1:34 PM

#

I have removed the class name

rigid phoenix Feb 23, 2023, 1:35 PM

#

Cool so in your select_difficulty scripts

#

remove the get node functions and just call Player.change_difficulty()

timid marten Feb 23, 2023, 1:36 PM

#

rigid phoenix Feb 23, 2023, 1:37 PM

#

Can you show me your autoload please?

timid marten Feb 23, 2023, 1:37 PM

#

hey can a signal cause a function to work?

#

I am thinking on creating three separate functions for easy medium and hard

rigid phoenix Feb 23, 2023, 1:39 PM

#

timid marten hey can a signal cause a function to work?

yes that is their purpose,

timid marten Feb 23, 2023, 1:39 PM

#

can you teach me to do that?

rigid phoenix Feb 23, 2023, 1:39 PM

#

lets step back and look at autoloads first

#

can I see how you configured it in your settings please?

timid marten Feb 23, 2023, 1:39 PM

#

because i thought it is hard to make a function work while giving a value too

timid marten Feb 23, 2023, 1:40 PM

#

rigid phoenix lets step back and look at autoloads first

I think autoload is gonna cause my game to not work

rigid phoenix Feb 23, 2023, 1:40 PM

#

Autoload's will work, we just need to modify some code

timid marten Feb 23, 2023, 1:40 PM

#

my player has the movements in its script and the damage it get

rigid phoenix Feb 23, 2023, 1:42 PM

#

Why don't you zip your project and send it to me

#

I'll make some adjustments and we can go from there

timid marten Feb 23, 2023, 1:43 PM

#

how to zip it?

rigid phoenix Feb 23, 2023, 1:44 PM

#

Windows 10 or 11?

timid marten Feb 23, 2023, 1:44 PM

#

11

rigid phoenix Feb 23, 2023, 1:44 PM

#

Right click project folder, compress to zip

#

alright, give me a bit. Need to download godot 3.5

timid marten Feb 23, 2023, 1:46 PM

#

i usually play scene from FirstScene

#

and it will go to menu and when you press start it will go to the game

#

now I am adding that selectdifficulty after that menu

rigid phoenix Feb 23, 2023, 1:54 PM

#

I see you're already using signals in the Events autoload script

timid marten Feb 23, 2023, 1:57 PM

#

yeah I just followed a tutorial

rigid phoenix Feb 23, 2023, 1:57 PM

#

gotcha

timid marten Feb 23, 2023, 1:58 PM

#

you did it??

rigid phoenix Feb 23, 2023, 1:58 PM

#

Still going 🙂

#

download took forever

#

with 3.5.1

#

Alright

#

done

#

I've cleaned up your folder structure a bit, it was hard to navigate.

#

Instead of making the player an autoload, I created a gamemanger script.

#

You can use this to store values which you can access anywhere

timid marten Feb 23, 2023, 2:10 PM

#

u done it?

timid marten Feb 23, 2023, 2:10 PM

#

rigid phoenix Instead of making the player an autoload, I created a gamemanger script.

what is that

rigid phoenix Feb 23, 2023, 2:10 PM

#

it's not best practice and you will most likely have issues further down the track, but I think you'll have other problems before you get to that.

timid marten Feb 23, 2023, 2:11 PM

#

I am just creating a project to pass

timid marten Feb 23, 2023, 2:11 PM

All i need is to create 3 levels

rigid phoenix Feb 23, 2023, 2:11 PM

#

school assignment?

timid marten Feb 23, 2023, 2:13 PM

#

yes

#

Damn dude you are good

#

are there any other changes here other than you moving the max_health to the autoload?

rigid phoenix Feb 23, 2023, 2:14 PM

#

Just the restructure of files

#

Move them as you will but it's alot easier to manage

#

Also i'm not happy with that answer, but it will do...

timid marten Feb 23, 2023, 2:16 PM

#

It will do

#

It is like the last requirement of my project

#

to have a difficulty system
