GameObject.FindGameObjectWithTag in JobComponentSystem

quick question. Is this allowed in a JobComponentSystem or is there a better way of doing this.

Code (CSharp):

1.        
2.     protected override void OnCreate()
3.     {
4.          // Get reference
5.          _gameSettings = GameObject.FindGameObjectWithTag("tagGameSettings").GetComponent<GameSettings>();
6.          if (_gameSettings == null)
7.              throw new InvalidOperationException("_gameSettings not found");
8.     }
9.  

 

Ok thanks for the quick reply

 

If you do want to do this you can use SceneManager.sceneLoaded callback and FindObject from there since objects might not even be initialized in OnCreate.

I was using this method to be able to tweak settings in the inspector and then pass those settings off to a system in the way they are here. I'm curious what you would recommend instead for that, or is this our best option for now?

 

I was going to try an use ConvertToEntity to get my gameSetting from a gameObject and convert it to entity data. Maybe this is not the right way either ?

 

When I tried this on the previous release my system was not able to find my converted entity - meaning the conversion process doesn't happen before OnCreate. I guess you can create an EntityQuery specifically for your settings entity or use GetSingleton every time you need to access it, seems a little akward though.

 

Im not sure I understand do you have a small code snipped I can look at for your idea of converting game object to entity and then using GetSingelton . First time ive heard of GetSingelton method

 

It's a method on ComponentSystem/JobComponentSystem. You can just call it from inside OnUpdate
