将子弹分为三个不同的方向

Question

我试图为一个投射物分配一项技能，当使用该技能时，将项目分为3个(原始投射物和2个新投射物(。

然而，当我实例化这两个克隆时，我无法将任何移动归因于它们。他们的想法是走这条路：

绿色虚线表示原始子弹的运动，蓝色矢量表示特殊激活时原始子弹的瞬时速度，红色矢量表示属于每个新生成子弹的两个速度矢量，绿色角度表示新子弹相对于原始速度方向的方向

但此刻，它们只是站在抛物线的点上，在那里它们被实例化了。无论我做什么，我似乎都无法对它们的刚体2D赋予任何价值。有人知道怎么解决这个问题吗？

这是我迄今为止的代码

能力脚本：

public class AirSpecialSplit : MonoBehaviour, IAirSpecial
{
public float SplitAngleInDegrees = 10;
GameObject bird_down;
GameObject bird_up;
public void ExecuteAirSpecial()
{
{
//hold the velocity of the original bird
Vector2 original_velocity = this.gameObject.GetComponent<Rigidbody2D>().velocity;
//clone two new birds
bird_down = Birb.MakeBirbCopy(this.gameObject);
bird_up = Birb.MakeBirbCopy(this.gameObject);
//get the rigidboy from the clones
Rigidbody2D rb_bird_down = bird_down.GetComponent<Rigidbody2D>();
Rigidbody2D rb_bird_up = bird_up.GetComponent<Rigidbody2D>();
rb_bird_down.velocity = new Vector2(original_velocity.x, original_velocity.y) * Time.deltaTime;
rb_bird_up.AddForce(new Vector2(3, 5) * 500);
}
}
}

主要鸟类：

public class Birb : MonoBehaviour
{
#region Provided Code, Do Not Edit
private Rigidbody2D m_rigidbody;
private bool m_canExecuteAirSpecial = true;
public bool CanExecuteAirSpecial
{
get
{
return m_rigidbody.simulated && m_canExecuteAirSpecial;
}
}
private void Awake()
{
m_rigidbody = GetComponent<Rigidbody2D>();
StopBirbSimulation();
}
public void StopBirbSimulation()
{
m_rigidbody.simulated = false;
}
public void StartBirbSimulation()
{
m_rigidbody.simulated = true;
}
public void SetPosition( Vector3 position )
{
if ( m_rigidbody.simulated )
{
m_rigidbody.MovePosition( position );
}
else
{
transform.position = position;
}
}
public void ExecuteAirSpecial()
{
GetComponent<IAirSpecial>().ExecuteAirSpecial();
m_canExecuteAirSpecial = false;
}
private void OnCollisionEnter2D( Collision2D collision )
{
m_canExecuteAirSpecial = false;
}
public static GameObject MakeBirbCopy( GameObject original )
{
Birb newBirb = Instantiate(original).GetComponent<Birb>();
newBirb.m_canExecuteAirSpecial = false;
return newBirb.gameObject;
}
#endregion
[Range( 0, 25 )]
public float LaunchForce = 12;
public void Launch(Vector3 offset, float maximumStretch, Rigidbody2D rigidbody)
{
rigidbody.velocity = new Vector2(offset.x * -LaunchForce, offset.y * -LaunchForce) * (maximumStretch/2);
}
}

好的，显然，我只需要设置；模拟的"；实例化后为true。

rb_bird_down.simulated = true;
rb_bird_up.simulated = true;

文档可能会更清楚地说明这一点，因为它们说所有属性都是复制的，但事实并非如此。。。
