在周围掉落物品

比如把怪物消灭了之后，爆出装备掉在四周

// 参考官方教程：Creator Kit - Beginner Code

public class SpawnerSample : MonoBehaviour
{
    public GameObject ObjectToSpawn;

    void Start()
    {
        int angle = 0;
        Vector3 spawnPosition = transform.position;

        Vector3 direction = Quaternion.Euler(0, angle, 90) * Vector3.right;
        spawnPosition = transform.position + direction * 2;
        Instantiate(ObjectToSpawn, spawnPosition, Quaternion.identity);

        angle = 55;
        direction = Quaternion.Euler(0, angle, 0) * Vector3.right;
        spawnPosition = transform.position + direction * 2;
        Instantiate(ObjectToSpawn, spawnPosition, Quaternion.identity);

        angle = 180;
        direction = Quaternion.Euler(0, angle, 0) * Vector3.right;
        spawnPosition = transform.position + direction * 2;
        Instantiate(ObjectToSpawn, spawnPosition, Quaternion.identity);
    }
}

可以把angle 改成随机数生成，这样每次不会掉在固定位置
