unity3D-攻击移动

1. 首先是人物的挂载文件

 // 定义变量

private IBattleCharacterContainer AttackTargetInfo = null; // 攻击目标信息集合
public Transform AttackTargetTrans = null;    // 攻击目标transform
private Vector2 MoveDistance = new Vector2 (4, 6);  //攻击后向后的移动距离
private Vector2 MoveDirLeft = new Vector2 (-70, -30); // 攻击后相对目标的移动角度
private Vector2 MoveDirRigh = new Vector2 (30, 70);   // 攻击后相对目标的移动角度

bool moveFlag = false; // 是否移动控制变量
float m_refcomSmoothTime  = 0.8f; // 移动所需要的时间
Vector3 m_refFix = Vector3.zero;
Vector3 moveToPos = Vector3.zero; // 计算后的移动位置

  // 对外接口1 攻击目标的设定

public void SetTargetInfo(IBattleCharacterContainer target)
{
    this.AttackTargetInfo = target;
    this.AttackTargetTrans = target.Controller.transform;
}

 // 攻击后移动的位置设置

void setMosterMoveTo ()    
{   
     float angle = UnityEngine.Random.Range(1, 3)== 1 ? UnityEngine.Random.Range (MoveDirLeft.x, MoveDirLeft.y) : 
                                                        UnityEngine.Random.Range (MoveDirRigh.x, MoveDirRigh.y);
     float distance = Math.Abs(angle) * MoveDistance.y / MoveDirRigh.y;
     transform.LookAt (AttackTargetTrans);
     Quaternion r0= Quaternion.Euler(transform.rotation.eulerAngles.x, transform.rotation.eulerAngles.y + angle, transform.rotation.eulerAngles.z);
     Vector3 movePos = (transform.position  + (r0 * Vector3.forward) * distance);
     moveFlag = true;
     moveToPos = movePos;
}

 // 攻击后移动的位置移动

void setMovetoPos ()
{
    transform.position = Vector3.SmoothDamp(transform.position, moveToPos, ref m_refFix, m_refcomSmoothTime);
    transform.LookAt (AttackTargetTrans);
    m_refcomSmoothTime -= Time.deltaTime;
    if(m_refcomSmoothTime <= 0)
    {
	m_refcomSmoothTime = 0.8f;
	transform.position = moveToPos;
	moveFlag = false;
     }
}

 

 3. Update 中人物正常移动的AI

private bool isMoving;

public void Update()
{
   float step = motionSpeed * Time.deltaTime;
   var motionDir = LookTarget - transform.position;
   if(motionDir.magnitude > Mathf.Epsilon)
   {
       var lookTowards = Quaternion.LookRotation(motionDir);
       transform.rotation = Quaternion.Slerp(transform.rotation, lookTowards, step);
    }
    if (CanMove)
    {
	if(AttackTargetTrans != null)
	{
	    if(AttackTargetInfo.CharacterVariableData.Hp <= 0)
	    {
		moveFlag = false;
		AttackTargetTrans = null;
		return;
	    }
	    else if(moveFlag == false && Vector3.Distance(transform.position, AttackTargetTrans.position) <= 5)
	    {
		 setMosterMoveTo();
		 return;
            }
	    else if(moveFlag == true)
	    {
		setMovetoPos();
		return;
	     }
	  }

         var newPos = Vector3.MoveTowards(transform.position, Target, step);
         transform.position = new Vector3(newPos.x, transform.position.y, newPos.z);
         var d = Vector3.Distance(newPos, Target);
         if (d <= 1.0f && isMoving)
         {
             isMoving = false;
             OnReachedMoveTarget(EventArgs.Empty);
         }
     }
 }

 Event ·登录

public event EventHandler ReachedMoveTarget;

 protected virtual void OnReachedMoveTarget(EventArgs e)
 {
        var handler = ReachedMoveTarget;
        if (handler != null)
            handler(this, e);
 }

 控制移动

 Controller.ReachedMoveTarget += characterController_ReachedMoveTarget;   
 private bool isNavigationStopped;

 private void characterController_ReachedMoveTarget(object sender, EventArgs e)
 {
    if (rail == null || isNavigationStopped)
    {
      Controller.Idle();
      return;
    }
    MoveOn();
  }
  private const float minRandomRadius = 2.0f;
  private const float maxRandomRadius = 5.0f;
  private void MoveOn()
  {
    if (rail == null)
       return;
    if (currentRailNodeIndex >= rail.Length - 1)
       return;
    currentRailNodeIndex++;
    var pos = rail[currentRailNodeIndex];
    var randomAngle = UnityEngine.Random.Range(0.0f, Mathf.PI * 2.0f);
    var randomRadius = UnityEngine.Random.Range(minRandomRadius, maxRandomRadius);
    var offsetX = Mathf.Cos(randomAngle) * randomRadius;
    var offsetZ = Mathf.Sin(randomAngle) * randomRadius;
    Controller.SetTarget(new Vector3(pos.x + offsetX, groundPosition, pos.z + offsetZ));
  }

 

 public void SetTarget(Vector3 target)
 {
      Target = target;
       LookTarget = target;
       isMoving = true;
  }
