為char_ethan新增指令碼DonePlayerMovement

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 parameter
	
	
	private 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);
	}
}
 

設定引數sneakingBool的值
判斷如果有按橫向或縱向鍵的話，執行Rotating (float horizontal, float vertical)實現玩家轉動功能
設定玩家速度為5.5，速度緩衝時間
否則，設定速度為0


Rotating (float horizontal, float vertical)：通過橫縱變數來控制玩家轉向
設定玩家要轉的目標方向，型別為vector3
將上述vector3變數設定為Quaternion（四元數，1，i，j，k），以便玩家轉向（LookRotation靜態函式可以使z軸轉向targetDirection（要面朝的方向），使y軸朝向上）
使玩家平滑的由當前角度轉向目標角度，Lerp（角色剛體當前旋轉值，目標旋轉值，旋轉速度）
設定玩家當前角度為轉過的新角度

AudioManagement (bool shout)：
判斷如果動作控制器獲得的狀態資訊為locomotionState時
判斷沒播放時
播放腳步聲
若不在locomotionState狀態
停止播放腳步聲
若喊叫為真
使用AudioSource函式自動建立一個物件，並在指定地點播放音效，之後物件自動銷燬，不會一直存在於場景中

回到unity，將Audio中的player_attractAttention拖到剛剛指令碼中的Shouting Clip中，設定喊叫音效


最後注意勾選Animator下的apply root motin，使玩家可以移動


執行。。。玩一下
