Problems with enums and switches (C#)

Questions & Answers

I’m working on my enemy AI here. What I’m trying to do is something similar to the standard character controller, where it just has a current character state enum, but what I’m doing with it is have a switch for said enum where it tells it what animation to play.

using UnityEngine;
using System.Collections;

enum EnemyState{IDLE = 0, WALK = 1, RUN = 2, ATTACK = 3, KILL = 4};

public class EnemyBehavior : MonoBehaviour
{

	public AnimationClip enemyIdle;//setting animations
	public AnimationClip enemyWalk;//walking
	public AnimationClip enemyRun;//running/chasing
	public AnimationClip enemyAttack;//attacking player
	public AnimationClip enemyKill;//killing player
	
	public Transform Player;//adds the player to the script
	
	public int WalkingSpeed = 1;//sets the normal walking speed
	public int RunningSpeed = 3;//sets the running (chase player) speed
	public int MaxDist= 15;//maximum distance the player can be before enemy stops chasing the player
	public int MinDist= 7;//how close the player can be to enemy for enemy to start chasing player
	EnemyState currentState;
	
	void Update()//when object enters the Sphere Collider (Chase Range)
	{
	 	if(Vector3.Distance(transform.position,Player.position) <= MaxDist)//if that object has the tag "Player"
		{
		  transform.LookAt(Player);//Looks at the player
			currentState = EnemyState.RUN;
 		  transform.position += transform.forward*RunningSpeed*Time.deltaTime;//follows the player
		}else if(Vector3.Distance(transform.position,Player.position) >= MaxDist)
		{
			RoamAround ();
		}
		switch (currentState)
		{
			case IDLE:
				animation.Play ("enemyIdle");
				break;
			case WALK:
				animation.Play ("enemyWalk");
				break;
			case RUN:
				animation.Play ("enemyRun");
				break;
			case ATTACK:
				animation.Play ("enemyAttack");
				break;
			case KILL:
				animation.Play ("enemyKill");
				break;
			default:
				animation.Play ("enemyIdle");
				break;
		}
	}
	void RoamAround()
	{
		currentState = EnemyState.IDLE;
	}
}

What I’m getting is errors like “The name `IDLE’ does not exist in the current context” for every single EnemyState.
What am I doing wrong?
(I’ve tried adding the enum into the class, but it doesn’t work like that either.)

In C# you have to put the Enum name as part of the qualifier:

switch(currentState)
{
  case EnemyState.IDLE:
  ...
  break;
}

Make EnemyState public and put it inside EnemyBehaviour and write using static EnemyBehaviour.EnemyState; at the top of the script.
This only works with DotNet 4.x +
