火箭耗子 5.1 AddForce 加前进的速度 设置离子的层 Physics2D.OverlapCircleAll

当按下鼠标的时候给物理加力 5.0后要获取组件然后加AddForce
public float jetpackForce = 75.0f;
    void FixedUpdate () 
{
bool jetpackActive = Input.GetButton("Fire1");

if (jetpackActive)
{
GetComponent<Rigidbody2D>().AddForce(new Vector2(0, jetpackForce));
}

Vector2 newVelocity =  GetComponent<Rigidbody2D>().velocity;速度矢量传递
newVelocity.x = forwardMovementSpeed;
GetComponent<Rigidbody2D>().velocity = newVelocity;
}

GetComponent<ParticleSystemRenderer> ().sortingLayerName="Player";   设置粒子系统的层级
GetComponent<ParticleSystemRenderer> ().sortingOrder  = -1;

Collider2D[] enemies = Physics2D.OverlapCircleAll(transform.position, bombRadius, 1 << LayerMask.NameToLayer("Enemies"));

这个方法定义了一个2D碰撞数组，以指定的顶点为圆心(transform.position)，设置圆的半径(bombRadius)，在指定的层(1 << LayerMask.NameToLayer("Enemies"))作用。
在这个层里指定圆的范围内添加所有包涵collider的个体。返回数组中的个体按照Z递增排列。
