I am currently working on a AI script and its no where near complete but i got this error and i dont understand what its trying to get me to do

using UnityEngine;
using System.Collections;

	public class NPC_AI : MonoBehaviour {

		public float Speed = 6.0f;
		public float rotateSpeed = 6.0f;
		public int Range = 20;
		
		public int minHealth = 1;
		public int curHealth = 100;
		public int maxHealth = 100;
		
		public int GiveXP;
		
		public Transform Player;

		// Use this for initialization
		void Start () {
	
		}
	
		// Update is called once per frame
		void Update () {
		
		if(curHealth < minHealth) {
			System.Object PlayerController = GetComponent<PlayerController>();
			PlayerController.XP += GiveXP();
		}
	}
}

I have a public int XP in my PlayerController script also and i just dont understand how im getting this error

The error is:

Assets/My Assets/Scripts/NPC/NPC_AI.cs(28,48): error CS1955: The member `NPC_AI.GiveXP' cannot be used as method or delegate

Any help is apppreciated

GiveXP is a variable, not a function so you need:

 PlayerController.XP += GiveXP;

i.e. no parentheses.

I don’t see a method GiveXP() inside your script. You only have a variable of type int with the same name. Try removing the parenthess from the line in which the error occurs:

PlayerController.XP += GiveXP;

But make sure you initialize a value to this variable first, say 10, for instance.

Or, you could actually implement a method called GiveXP(), like this:

public int GiveXP()
{
return 10;
}

In which case you wouldn’t need the GiveXP variable.
