#

Hello, guys! I got a reference issue but I am not sure why? I have tried to add some debug.log statements to figure it out it says that the issue persists somewhere in my PlayerController script at the lines it says in console. Is someone available to help figure it out?

#

I will be off for a while. So, I am going to send all the information needed for that issue and after that we will catch it up when we left it.

#

objectPooling is null so it hasn't been assigned in the inspector

visual fractal Mar 3, 2024, 11:10 AM

#

#

Yeah

#

The problem is that I have a parent game object for object pooling and child game objects

#

#

Here

#

The parent is empty on inspector

visual fractal Mar 3, 2024, 11:11 AM

#

visual fractal

and my child game objects are that I send you

sullen fable Mar 3, 2024, 11:11 AM

#

no, it hasn't been assigned in the player controller

visual fractal Mar 3, 2024, 11:11 AM

#

Yes I see it before I had it as an instance

#

I mean I did something like

#

public static ObjectPooling Instance

#

I thought if maybe the problem was with that and change iut

#

it

#

So, now yeah I have to assign it inside player controoler

#

But don't know which object to assign?

sullen fable Mar 3, 2024, 11:12 AM

#

The one that you want it to use

visual fractal Mar 3, 2024, 11:13 AM

#

The issues persist it says at these lines

sullen fable Mar 3, 2024, 11:14 AM

#

Show the player controller's inspector

swift verge Mar 3, 2024, 11:15 AM

#

Could you show RoundManager script?

visual fractal Mar 3, 2024, 11:15 AM

#

Yes

visual fractal Mar 3, 2024, 11:16 AM

#

sullen fable Show the player controller's inspector

Here

swift verge Mar 3, 2024, 11:16 AM

#

swift verge Could you show RoundManager script?

Whoops i made a silly mistake, i was meant to be looking at line 85 i was looking at 58

visual fractal Mar 3, 2024, 11:17 AM

#

No problem I am going to send all of my scripts at the top so you can see them. I have sent already 2 of them

sullen fable Mar 3, 2024, 11:17 AM

#

There's no field in the inspector for the object pooling?

swift verge Mar 3, 2024, 11:17 AM

#

Anyway, where are you setting/initializing objectPooling?

#

ugh i read the wrong line again

visual fractal Mar 3, 2024, 11:18 AM

#

sullen fable There's no field in the inspector for the object pooling?

I made it singleton

public static ObjectPooling Instance;

sullen fable Mar 3, 2024, 11:19 AM

#

why

visual fractal Mar 3, 2024, 11:19 AM

#

Because thats how I had it before

sullen fable Mar 3, 2024, 11:19 AM

#

Before, when it also didn't work?

visual fractal Mar 3, 2024, 11:19 AM

#

I was just wondering if I am going to change that and take reference what will happen

#

Yes

swift verge Mar 3, 2024, 11:19 AM

#

in your playerController script you say that objectpooling.cs exists but not which one exists

visual fractal Mar 3, 2024, 11:19 AM

#

IT doesn't work for both of them

sullen fable Mar 3, 2024, 11:19 AM

#

Put it back the way it was and assign the reference in the inspector

visual fractal Mar 3, 2024, 11:20 AM

#

Yeah but in player controller which object to assign there thats what I dont understand

#

I have collision, gemparticle and logs

#

Those are childs of object pooling game object

swift verge Mar 3, 2024, 11:20 AM

#

Okay well, where is objectPooling.cs? is it attached to an object or is somewhere else?

visual fractal Mar 3, 2024, 11:21 AM

#

sullen fable Mar 3, 2024, 11:21 AM

#

Well which one of them do you want to use?

visual fractal Mar 3, 2024, 11:21 AM

#

It is here inside my childs

#

Object pooling cs

#

Parent is empty in inspector

swift verge Mar 3, 2024, 11:21 AM

#

So logsPooling, GemParticelPooling and collisionParticle pooling all have the ObjectPooling.cs Script on them?

visual fractal Mar 3, 2024, 11:21 AM

#

Can I make like different classes for each of them

sullen fable Mar 3, 2024, 11:21 AM

#

I assume you want to use gem particle pooling when the bird collides with a gem, right?

visual fractal Mar 3, 2024, 11:21 AM

#

yes

sullen fable Mar 3, 2024, 11:22 AM

#

and log pooling when it collides with a log?

visual fractal Mar 3, 2024, 11:22 AM

#

of course

#

collision when player collides with the log

#

collisionParticle

sullen fable Mar 3, 2024, 11:22 AM

#

Then you obviously can't use one field to store all of them

visual fractal Mar 3, 2024, 11:22 AM

#

logs is for instantiating this game object

#

logsPooling I mean

swift verge Mar 3, 2024, 11:22 AM

#

visual fractal

Okay well your playerController script knows that ObjectPooling.cs exists but it doesnt know that all these objects exists, you need to get a reference to ObjectPooling.cs on these objects.

sullen fable Mar 3, 2024, 11:22 AM

#

public ObjectPooling gemObjectPooling;
public ObjectPooling logObjectPooling;
public ObjectPooling collisionObjectPooling;

#

then use whichever variable you need in the code

swift verge Mar 3, 2024, 11:23 AM

#

Yes ^

visual fractal Mar 3, 2024, 11:23 AM

#

sullen fable ```cs public ObjectPooling gemObjectPooling; public ObjectPooling logObjectPooli...

That will be on my player controller script?

swift verge Mar 3, 2024, 11:23 AM

#

yup

sullen fable Mar 3, 2024, 11:23 AM

#

that's where you use the variables, right?

visual fractal Mar 3, 2024, 11:24 AM

#

I dont think so because OP.cs is responsible for that like I said before I have OP.cs inside my child game objects

swift verge Mar 3, 2024, 11:24 AM

#

visual fractal Mar 3, 2024, 11:24 AM

#

Yeah that does nothing and I was wondering

#

I have to get the refernce

swift verge Mar 3, 2024, 11:25 AM

#

yes

#

Nitku just showed you how to get the reference

visual fractal Mar 3, 2024, 11:25 AM

#

Ok I am going to make it on playe controller

sullen fable Mar 3, 2024, 11:26 AM

#

How the objects are arranged in the hierarchy has absolutely nothing to do with it

visual fractal Mar 3, 2024, 11:26 AM

#

You mean it doesn't matter where i am going to use those variables?

swift verge Mar 3, 2024, 11:26 AM

#

https://pastebin.com/4amgrWfV copy this into PlayerController.cs, go to where ever it is on the player and set the references

What is that?

#

Guys I didn't want you to solve it for me but anyway XD

sullen fable Mar 3, 2024, 11:29 AM

#

You're lacking skills in very basic Unity/C# concepts so it's hard to do otherwise

swift verge Mar 3, 2024, 11:30 AM

#

Nitku did also tell you what you needed to do earlier but you just like didnt

visual fractal Mar 3, 2024, 11:30 AM

#

I know how to set references and all of that I am using unity 1 year already I was just confused where I have to use that references cuz I have OP.cs and PC.cs

sullen fable Mar 3, 2024, 11:31 AM

#

If you don't know that you have to set the values of variables in the same script where you use them, that's a very basic issue

visual fractal Mar 3, 2024, 11:33 AM

#

I am working on that game with a guy by the way he is a collaborator and trying to help me with the game. This part was made by him, so I wasn't sure what he did here XD.

#

He just left for me some issues to handle myself

swift verge Mar 3, 2024, 11:34 AM

#

Ahh that makes sense

sullen fable Mar 3, 2024, 11:35 AM

#

These aren't the kind of things that would be different depending on who wrote the code

visual fractal Mar 3, 2024, 11:40 AM

#

Guys I have to leave somewhere now it is a need, so I will come back and we will continue for now I have to close it. Thanks!

visual fractal Mar 3, 2024, 6:58 PM

#

Hello, guys! Are you there?

#

Before closing the thread I have a very small issue to solve.

swift verge Mar 4, 2024, 5:35 AM

#

@visual fractal the issue?

visual fractal Mar 4, 2024, 12:28 PM

#

swift verge <@827977889978384396> the issue?

So, what I want to do is to actually enable and disable my options ui elements in main menu scene. In main menu I have a button which says Options. So, what I done before was to load the options scene when clicking that button. Now, I got confused of how to make my options scene enable and disable I dont want to load a new scene.

swift verge Mar 4, 2024, 12:29 PM

#

Just set it unactive
