Animating an enemy and changing states

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Enemy : MonoBehaviour {
5. public Transform thisObject;
6. public Transform target;
7. private NavMeshAgent navComponent;
8. Animator anim;
9. int runningStateHash = Animator.StringToHash("Base Layer.Running");
10. int walkingStateHash = Animator.StringToHash("Base Layer.Walking");
11.  
12.  
13.     void Start()
14.     {
15.         target = GameObject.FindGameObjectWithTag("Player").transform;
16.         navComponent = this.gameObject.GetComponent<NavMeshAgent>();
17.         anim = GetComponent<Animator> ();
18.     }
19.  
20.     void OnTriggerEnter(Collider col)
21.     {
22.         AnimatorStateInfo stateInfo = anim.GetCurrentAnimatorStateInfo (0);
23.     }
24.  
25.     void OnTriggerExit(Collider col)
26.     {
27.         AnimatorStateInfo stateInfo = anim.GetCurrentAnimatorStateInfo (1);
28.     }
29.        
30.     void Update()
31.     {
32.         float dist = Vector3.Distance(target.position, transform.position);
33.         float move = Input.GetAxis ("Vertical");
34.         anim.SetFloat ("Speed", move);
35.    
36.  
37.         if(target)
38.         {
39.             navComponent.SetDestination(target.position);
40.         }
41.  
42.         else
43.         {
44.             if(target = null)
45.             {
46.                 target = this.gameObject.GetComponent<Transform>();
47.             }
48.             else
49.             {
50.                 target = GameObject.FindGameObjectWithTag("Player").transform;
51.             }
52.         }
53.     }
54. }

I'm using the following code to call animations with the OnTriggerEnter and Exit functions, and I want to call seperate animations depending on if you are in the trigger or not. How can I call seperate animations other than how I am doing it?

 

Are you looking for something like OnTriggerStay?

 

Ok, so using

Code (CSharp):

1.     void OnTriggerStay(Collider col)
2.     {
3.         if (col.attachedRigidbody)
4.         {
5.  
6.         }
7.     }
8.  

How would I call each animation? I set them as variables(or integers) with

Code (CSharp):

1. int runningStateHash = Animator.StringToHash("Base Layer.Running");
2. int walkingStateHash = Animator.StringToHash("Base Layer.Walking");
3.  

How would I call each individual one?

 

I usually do something like this to toggle a parameter in the animator, your layers in the Animator should then know what to do if the animator is setup correctly.

Code (CSharp):

1.     void OnTriggerStay(Collider other){
2.         if(other.attachedRigidbody){
3.             GetComponent<Animator>().SetBool("Running", true);
4.         }
5.     }
6.  
7.     void OnTriggerExit(Collider other){
8.         if(other.attachedRigidbody){
9.             GetComponent<Animator>().SetBool("Running", false);
10.         }
11.     }
12.  

 

I set everything up, and he now walks when I am outside the trigger, but when I enter the trigger, he only sprints for a few seconds, then walks, then sprints again. I think it might be because I have a transition between the two? Should I only have 1 transition?
