The name '' does not exist in the current context

So what I’m trying to do is call a function from another script.

public class Manager  
{
         // Use this for initialization
	 void Start()
        {
        SetPlayerPosition();
	}
}

okay that’s the Manager Sample , here the other

public class Player : MonoBehaviour 
{
    
   
	// Use this to set Player Position
     public void SetPlayerPosition()
     {
      transform.position = new Vector3(150, 0, 5);
     }

}

I know this might be a simple question but this is bugging me since Ive done it before, I might even answer this myself after further research but just to post in case someone has same problem in future.

Note: The error is on the Manager.cs “The name ‘SetPlayerPosition’ does not exist in the current context”

You need to create a reference to a specific instance of the Player script (i.e. to the game object it is attached to). The multiple ways to do this are covered here:

Accessing Other GameObjects

Then you will use a variable pointing to that instance of the script to make the access. Something like:

playerScript.SetPlayerPosition();

I tried this and it worked thanks for your help.

 void Start()
{
        GameObject player = GameObject.FindGameObjectWithTag("Player");
        player.GetComponent<Player>().SetPlayerPosition();
}
