How can I create a object???

Hello I can't creat a simple object from one of my classes, unity keep sending me a warning message like this

You are trying to create a MonoBehaviour using the 'new' keyword. This is not allowed. MonoBehaviours can only be added using AddComponent(). Alternatively, your script can inherit from ScriptableObject or no base class at all
UnityEngine.MonoBehaviour:.ctor()

and I know I can't creat an object that inherit from a monoBehavior using the word new, but how can I do that ???

 

Post some code using code tags please and what is it you are trying to do? Why are you creating a the class?

 

I'm trying to do this :
Player_Movement_Controller_Class playerMovementControllerObject = new Player_Movement_Controller_Class();

The class inherit from MonoBehavior

 

It's telling you exactly what to do. You use AddComponent to add a script to an existing gameobject.

 

Code (csharp):

1.  
2. Class A : Monobehaviour
3. {
4. public int x = 10;
5. ///some code.
6. }
7.  

Instead of:

Code (csharp):

1. ClassA a = new ClassA();

Put Monobehaviour class on a gameObject and use

Code (csharp):

1. ClassA a = gameObject.GetComponent<ClassA>();

OR
to attach a component on GameObject use

Code (csharp):

1. ClassA a = gameObject.AddComponent<ClassA>();

 

But now I can't use my object !!!

 

Then you're going to have to provide more info on what you are doing because we aren't going to have a clue how to help you with what info you provided.

 

I have Instantiated the object like he said, but I can't use the methods outside of the start function

void Start()
{
Player_Movement_Controller_Class playerMovementControllerObject = gameObject.GetComponent<Player_Movement_Controller_Class>();
}

 

Did you declare your methods in that class as public?

 

That's because you are declaring your variable as local and not global.

You should be doing this

Code (CSharp):

1. Player_Movement_Controller_Class playerMovementControllerObject;
2.  
3. void Start()
4. {
5. playerMovementControllerObject = gameObject.GetComponent<Player_Movement_Controller_Class>();
6. }
7.  
8. void SomeOtherMethod()
9. {
10. playerMovementControllerObject .DoSomethingMethod();
11. }

And as @cstooch mentioned, public methods if they aren't already.

 

Jeez, my reading comprehension has been crap these days. Haha I misread the post. While public methods would be needed, the issue is definitely related to what you pointed out.. scope of the component instance he created.

I initially took the post as meaning that he couldn't access any methods in the class except Start (which really makes no sense he'd be calling that, but I still didn't quite catch on ).

 

I just want to thanks everyone for the help.
