投掷后产生 [英] Spawn after throw

问题描述

我正在做一个足球比赛项目.我想要一个球体，在抛出第一个球体后，我必须生成另一个球体.这是我尝试过的:

I am working on a football game project. I want a sphere I have to spawn another sphere after I throw the 1st sphere. Here's something I tried:

public class spawn : MonoBehaviour {
    public Transform[] SpawnPoints;
    public float SpawnTime;
    public GameObject ball;

    // Use this for initialization
    void Start () {
        InvokeRepeating ("SpawnBalls", SpawnTime, SpawnTime);
    }

    void SpawnBalls(){
        if (transform.position.z > -0.904 ) {
            int SpawnIndex = Random.Range (0, SpawnPoints.Length);
            Instantiate (ball, SpawnPoints [SpawnIndex].position, SpawnPoints [SpawnIndex].rotation);
        }
    }
} 

推荐答案

如果最后掷出的球足够远，则只需实例化一个新球.试试这个:

Simply instantiate a new ball if the last ball thrown is far enough. Try this:

public class spawn : MonoBehaviour {
    public Transform[] SpawnPoints;
    public GameObject ball;
    public GameObject lastBall;

    // Use this for initialization
    void Start () {
        int SpawnIndex = Random.Range (0, SpawnPoints.Length);
        lastBall = Instantiate (ball, SpawnPoints [SpawnIndex].position, SpawnPoints [SpawnIndex].rotation) as GameObject;
    }

    void Update(){
        if (lastBall.position.z > -0.904 ) {
            int SpawnIndex = Random.Range (0, SpawnPoints.Length);
            lastBall = Instantiate (ball, SpawnPoints [SpawnIndex].position, SpawnPoints [SpawnIndex].rotation) as GameObject;
        }
    }
}
