unity freezes when running sprinting animation
I followed the beginning of the mecanim unity tutorial and now I was trying to add a sprint animation, so that locomotion is walking and another blend tree is running. I created a new Blend tree, and a transition from locomotion to the running blend tree, and the condition is: "Sprint" is true. Locomotion and the other animations work fine, but when I press the left shift button, unity freezes. This is the BotControlScript:
![using UnityEngine;
using System.Collections;
// Require these components when using this script
[RequireComponent(typeof (Animator))]
[RequireComponent(typeof (CapsuleCollider))]
[RequireComponent(typeof (Rigidbody))]
public class BotControlScript : MonoBehaviour
{
[System.NonSerialized]
public float lookWeight; // the amount to transition when using head look
[System.NonSerialized]
public Transform enemy; // a transform to Lerp the camera to during head look
public float animSpeed = 1.5f; // a public setting for overall animator animation speed
public float lookSmoother = 3f; // a smoothing setting for camera motion
public bool useCurves; // a setting for teaching purposes to show use of curves
private Animator anim; // a reference to the animator on the character
private AnimatorStateInfo currentBaseState; // a reference to the current state of the animator, used for base layer
private AnimatorStateInfo layer2CurrentState; // a reference to the current state of the animator, used for layer 2
private CapsuleCollider col; // a reference to the capsule collider of the character
static int idleState = Animator.StringToHash("Base Layer.Idle");
static int locoState = Animator.StringToHash("Base Layer.Locomotion"); // these integers are references to our animator's states
static int jumpState = Animator.StringToHash("Base Layer.Jump"); // and are used to check state for various actions to occur
static int jumpDownState = Animator.StringToHash("Base Layer.JumpDown"); // within our FixedUpdate() function below
