Time.timeSinceLevelLoad

切换到手册
public static float timeSinceLevelLoad ;

描述

The time since this frame started (Read Only). This is the time in seconds since the last non-additive scene has finished loading.

This behaves in the same way as Time.time with a negative offset.

//Attach this script to a GameObject
//Create a Button (Create>UI>Button) and a Text GameObject (Create>UI>Text)
//Click on the GameObject and attach the Button and Text in the fields in the Inspector

//This script outputs the time since the last level load. It also allows you to load a new Scene by pressing the Button. When this new Scene loads, the time resets and updates.

using UnityEngine; using UnityEngine.SceneManagement; using UnityEngine.UI;

public class TimeSinceLevelLoad : MonoBehaviour { public Button m_MyButton; public Text m_MyText;

void Awake() { // Don't destroy the GameObject when loading a new Scene DontDestroyOnLoad(gameObject); // Make sure the Canvas isn't deleted so the UI stays on the Scene load DontDestroyOnLoad(GameObject.Find("Canvas"));

if (m_MyButton != null) // Add a listener to call the LoadSceneButton function when the Button is clicked m_MyButton.onClick.AddListener(LoadSceneButton); }

void Update() { // Output the time since the Scene loaded to the screen using this label m_MyText.text = "Time Since Loaded : " + Time.timeSinceLevelLoad; }

void LoadSceneButton() { // Press this Button to load another Scene // Load the Scene named "Scene2" SceneManager.LoadScene("Scene2"); } }
