这次的代码示例是配合动画系统使用的
4.3新的动画系统允许动画带有位置偏移，只需要在Animator组件中勾选Apply Root Motion我们就可以使用它了。
using UnityEngine;
using System.Collections;public class DonePlayerMovement : MonoBehaviour
{
public AudioClip shoutingClip; // Audio clip of the player shouting.
public float turnSmoothing = 15f; // A smoothing value for turning the player.
public float speedDampTime = 0.1f; // The damping for the speed parameterprivate Animator anim; // Reference to the animator component.
private DoneHashIDs hash; // Reference to the HashIDs.void Awake ()
{
// Setting up the references.
anim = GetComponent<Animator>();
hash = GameObject.FindGameObjectWithTag(DoneTags.gameController).GetComponent<DoneHashIDs>();// Set the weight of the shouting layer to 1.
anim.SetLayerWeight(1, 1f);
}void FixedUpdate ()
{
// Cache the inputs.
float h = Input.GetAxis("Horizontal");
float v = Input.GetAxis("Vertical");
bool sneak = Input.GetButton("Sneak");MovementManagement(h, v, sneak);
}void Update ()
{
// Cache the attention attracting input.
bool shout = Input.GetButtonDown("Attract");// Set the animator shouting parameter.
anim.SetBool(hash.shoutingBool, shout);AudioManagement(shout);
}void MovementManagement (float horizontal, float vertical, bool sneaking)
{
// Set the sneaking parameter to the sneak input.
anim.SetBool(hash.sneakingBool, sneaking);// If there is some axis input...
if(horizontal != 0f || vertical != 0f)
{
// ... set the players rotation and set the speed parameter to 5.5f.
Rotating(horizontal, vertical);
anim.SetFloat(hash.speedFloat, 5.5f, speedDampTime, Time.deltaTime);
}
else
// Otherwise set the speed parameter to 0.
anim.SetFloat(hash.speedFloat, 0);
}void Rotating (float horizontal, float vertical)
{
// Create a new vector of the horizontal and vertical inputs.
Vector3 targetDirection = new Vector3(horizontal, 0f, vertical);// Create a rotation based on this new vector assuming that up is the global y axis.
Quaternion targetRotation = Quaternion.LookRotation(targetDirection, Vector3.up);// Create a rotation that is an increment closer to the target rotation from the player‘s rotation.
Quaternion newRotation = Quaternion.Lerp(rigidbody.rotation, targetRotation, turnSmoothing * Time.deltaTime);// Change the players rotation to this new rotation.
rigidbody.MoveRotation(newRotation);
}void AudioManagement (bool shout)
{
// If the player is currently in the run state...
if(anim.GetCurrentAnimatorStateInfo(0).nameHash == hash.locomotionState)
{
// ... and if the footsteps are not playing...
if(!audio.isPlaying)
// ... play them.
audio.Play();
}
else
// Otherwise stop the footsteps.
audio.Stop();// If the shout input has been pressed...
if(shout)
// ... play the shouting clip where we are.
AudioSource.PlayClipAtPoint(shoutingClip, transform.position);
}
}
