Instantiate prefab doesn't assign variables

I try to enable and disable different canvases with a left mouse click on game objects with Raycasts. But I instantiete it from prefabs so it doesnt save the Main Camera and Canvas I want to disable and enable.

I know how to do it with GameObject:

Code (CSharp):

1. cameraCheck = GameObject.FindWithTag( "MainCamera" );

but GameObject and Canvas/Camera dont have a FindWithTag? So I try FindObjectOfType which gives me all kinds of errors.

Code (CSharp):

1. void Start()
2.     {
3.         canvasBuilding.enabled = false;
4.         cameraCheck = FindObjectOfType<Camera>.tag "MainCamera";
5.         canvasBuilding = FindObjectOfType<Canvas>.tag "Building_01";
6.     }

Code (CSharp):

1. void Start()
2.     {
3.         canvasBuilding.enabled = false;
4.         cameraCheck = Camera.FindObjectOfType<Camera>().tag "MainCamera";
5.         canvasBuilding = Canvas.FindObjectOfType<Canvas>().tag "Building_01";
6.     }

It just all doesnt seem to work.

Thank you for your time

 

First off, you can replace

Code (CSharp):

1. cameraCheck = GameObject.FindWithTag( "MainCamera" );

with

Code (CSharp):

1. cameraCheck = Camera.main;

And if you want to keep track of the objects you're instantiating then just store them when you create them
eg.

Code (CSharp):

1. Canvas canvasBuilding = Instantiate(CanvasPrefab);

 

Thanks! Camera.main; worked!

Only I would like to set my canvas similar, and call it by its tag. Ive tried

Code (CSharp):

1. canvasBuilding = Canvas.FindObjectOfType<Canvas>().GetComponent<BuildingUnitsCanvas>();

I can't know how to set it up in Start() to the right Canvas I want to enable and disable


Thank you
