error CS0029: Cannot implicitly convert type `GameController' to `UnityEngine.GameObject'

How to fix this: Cannot implicitly convert type `GameController' to `UnityEngine.GameObject'
I have already stated:
public GameController gameController;
public GameObject gameControllerObject;
public GameObject GameController;

 

Your variable name begins with a capital, it thinks it's another object. Change it too gameController.

 

public GameController gameController;
public GameObject gameControllerObject;
public GameObject GameController;

 

Code (CSharp):

1. GameController gameControllerTypeComponent = GetComponent<GameController>()

returns an object of type GameController. Assigning it to a variable of Type GameObject is not going to work and produce the error you got.

Code (CSharp):

1. GameObject gameControllerObject = GetComponent<GameController>().gameObject

This will work since the variable gameObject of any Component will return an object of type GameObject.

If you are unable to fix your issue with that we need more code to look at.

 

Thanks Guys, I've tried all the above, but still same error (+others)
Here's the script now:

//public GameObject gameControllerObject;
public GameController gameController;
//public GameObject gameController;



void Start()
{GameObject gameController=GameObject.FindWithTag("GameController");

if(gameControllerObject!= null)
{
gameController= gameControllerObject.GetComponent<GameController>();
}
if(gameController==null)
{Debug.Log("Can not find 'Game Controller' script");
}
}

 

Please use code tags to wrap your code and make it readable. Here's an explanation on how to do that:
http://forum.unity3d.com/threads/using-code-tags-properly.143875/

It's quite obvious though:

Code (CSharp):

1. public GameController gameController;

You are defining gameController as a variable of type GameController.

Code (CSharp):

1. GameObject gameController=GameObject.FindWithTag("GameController")

Here you are trying to re-define gameController as type GameObject.

This is simply not going to work.

I think what you really want to do is this:

Code (CSharp):

1. public GameObject gameControllerObject;
2. public GameController gameController;
3.  
4. void Start()
5. {
6.     gameControllerObject = GameObject.FindWithTag("GameController");
7.  
8.     if(gameControllerObject != null)
9.     {
10.         gameController = gameControllerObject.GetComponent<GameController>();
11.     }
12.  
13.     if(gameController == null)
14.     {
15.         Debug.Log("Can not find 'Game Controller' script");
16.     }
17. }

• Declare variable types once, either at the beginning of the class or as a local variable within your methods.
• When assigning values to variables, you do not need to declare the type again if that has been done before.
• Use a naming which helps you to easily identify which variable serves which purpose. Having GameController, GameControllerObject, GameControllerComponent and so all declared as variables at the same time will almost certainly cause confusion for you and anyone else trying to read and understand your code.

From your questions I strongly recommend to have a look at C# basics about fields, properties, methods, value assignment and alike first.

 

Thanks Manlaiken,
Thanks Glockenbeat'

Works fine except needed L6.: GameObject gameControllerObject....
