How to Implement Delays in Unity for Gameplay and Event Sequencing?

UNITY delay implementation detailed explanation

Creating delay in Unity is essential for managing game processes, sorting events, and simulation of real world behavior. Here are several methods to achieve delay:

<.> 1.

/

WaitForSeconds WaitForSecondsRealtime

: Declarier a coroutine function.
• StartCoroutine : The execution of the designated time (affected by the speed of the game).
• WaitForSeconds: The execution of the specified time (not affected by the speed of the game).
• Example: WaitForSecondsRealtime
<.> 2. Time -based cycle

Use or

cycle: gradually increase the timer until it reaches the required value.

<code class="language-C#">IEnumerator WaitForSecondsExample()
{
    // 旋转90度
    transform.Rotate(Vector3.right * 90);

    // 等待4秒（不受游戏速度影响）
    yield return new WaitForSecondsRealtime(4);

    // 旋转40度
    transform.Rotate(Vector3.right * 40);

    // 等待2秒（受游戏速度影响）
    yield return new WaitForSeconds(2);

    // 旋转20度
    transform.Rotate(Vector3.right * 20);
}</code>

: Pay the execution of a frame.

• Example: Time.deltaTime while for
<.> 3.
• / Function yield return null

: The execution was suspended until the condition was true.

<code class="language-C#">IEnumerator TimeBasedLoopExample()
{
    // 旋转90度
    transform.Rotate(Vector3.right * 90);

    // 等待4秒（受游戏速度影响）
    float timer = 0;
    while (timer < 4)
    {
        timer += Time.deltaTime;
        yield return null;
    }

    // 旋转40度
    transform.Rotate(Vector3.right * 40);

    // 等待2秒（不受游戏速度影响）
    timer = 0;
    while (timer < 2)
    {
        timer += Time.deltaTime;
        yield return null;
    }

    // 旋转20度
    transform.Rotate(Vector3.right * 20);
}</code>

<<>

: The execution is suspended when the condition is true. WaitUntil WaitWhile <示> Example:

• <.> 4. Function WaitUntil
• <<> WaitWhile: Arrange a function after the delay is delayed.

<<>

: Similar to , but the function is repeatedly called with a specified time interval.

<code class="language-C#">IEnumerator WaitUntilExample()
{
    // 等待玩家分数达到100
    yield return new WaitUntil(() => playerScore >= 100);

    // 加载下一关
    SceneManager.LoadScene("NextLevel");
}</code>

Example:

Invoke <.> 5. Based on

delay

• Invoke
: Used to measure the time between the frames.
• The timer variable InvokeRepeating: each frame increases until it reaches the required value. Invoke
The statement

: Check whether the timer reaches the required value and execute the necessary code.

Example:

<code class="language-C#">Invoke("FeedDog", 5); // 5秒后调用FeedDog()

InvokeRepeating("MovePlayer", 0.5f, 0.2f); // 每0.2秒调用MovePlayer()，持续0.5秒。</code>
