倒计数

IEnumerator PowerupCountdownRoutine() {
    yield return new WaitForSecond(7);
    hasPowerup = false;
}

设置一个物体的显示与隐藏

public GameObject powerupIndicator;

powerupIndicator.gameObject.SetActive(true);
powerupIndicator.gameObject.SetActive(false);

统计场景中，某一标签物体的数量

enemyCount = FindObjectOfType().Length;

刚体附加切向力

targetRb.AddTorque(Random.Range(-10, 10), Random.Range(-10, 10)

鼠标点击事件

private void OnMouseDown() {
    Destroy(gameObject);
}

间隔特定时间产生对象

public List targets;

IEnumerator SpawnTarget() {
    while(true) {
         yield return new WaitForSeconds(spawnRate);
         int index = Random.Range(0, targets.Count);
         Instantiate(targets[index]);
    }
}

下面是List在界面中的展示

切换视图至2D

创建ui

public TextMeshProUGUI scoreText;

scoreText.text = "Score: " + score ;

根据对象名获取对象

private GameManager gameManager;

gameManager = GameObject.Find("Game Manager").GetComponent();

场景管理

重新加载当前场景，从而实现游戏重启

using UnityEngine.SceneManaggement;

public void RestartGame() {
    SceneManager.LoadScene(SceneManager.GetActiveScene().name);
}

界面按钮

using UnityEngine.UI;

private Button button;

button = GetComponent();

按钮绑定事件

button.onClick.AddLIistener(SetDifficulty);

void SetDifficulty() {
    ...
}
