Acessing a Script Instance from Another Object

Questions & Answers
1

I have this script:

using UnityEngine;
using System.Collections;

public class Menu_Options : MonoBehaviour 
{
	//Vars
	public Material GUI_N;
	public Material GUI_O;
	public static bool Active = false;
	public Transform Menu;
	public GameObject Cam;
	//Functions
	void OnMouseEnter()
	{
		renderer.material = GUI_O;
		Active = true;
	}
	void OnMouseExit()
	{
		renderer.material = GUI_N;
		Active = false;
	}
	void Update()
	{
		if(Active)
		{
			if(Input.GetMouseButtonUp(0))
			{
				Options();
				Debug.Log("Options");
			}
		}
	}
	void Options()
	{
		var s = Cam.GetComponent<SmoothCam>();
		s.Instance._SetTarget(Menu);
	}
}

But i get this error:

Assets/Scripts/Menu_Options.cs(37,19): error CS0176: Static member `SmoothCam.Instance' cannot be accessed with an instance reference, qualify it with a type name instead

This is how the other script is set up:

using UnityEngine;
using System.Collections;

public class SmoothCam : MonoBehaviour {

	public static SmoothCam Instance;
	
	void Awake()
	{
		Instance = this;
	}
	
	public void _SetTarget(Transform t)
	{
		target = t;
	}
    ---The rest is not important---

What does “qualify it with a type name” mean, and how can i fix or work around this?

Try something like this:

public class Menu_Options : MonoBehaviour {
	private SmoothCam SmoothCamScript;

	void Awake() {
		SmoothCamScript = Cam.GetComponent<SmoothCam>();
	}
	...
	SmoothCamScript._SetTarget(Menu);

I’ve never tried anything with an ‘instance’ in the other script, but this method usually works for me :slight_smile:

I think

var s = Cam.GetComponent<SmoothCam>();

should become

SmoothCam s = Cam.GetComponent<SmoothCam>();

because it defines the type s is.

Then if you want to run some function or get some variable off of that script use it like this

s._SetTarget(transform);

Hope this helps.

Your “Instance” variable is static, you don’t need to obtain an instance to access it

void Options() {
   var s = Cam.GetComponent<SmoothCam>();
   s.Instance._SetTarget(Menu);
}

Just do

SmoothCam.Instance._SetTarget(Menu);
