【Unity教程】从0编程制作类银河恶魔城游戏_哔哩哔哩_bilibili
教程源地址:https://www.udemy.com/course/2d-rpg-alexdev/
游戏界面切换到比如说菜单,装备栏时候游戏就会暂停,防止换装备的时候被打
红色的部分改成未缩放的时间,防止黑屏时候暂停
GameManager.cs
修改部分!!!
功能分析:
- 这个函数控制的是游戏的暂停与恢复。
Time.timeScale
是 Unity 中控制时间流逝的属性:Time.timeScale = 0
表示暂停游戏,即时间不再流动,所有物理和动画等都会暂停。Time.timeScale = 1
恢复游戏的正常速度,即时间流动恢复正常。
作用:
- pause为true: 游戏会被暂停,所有的时间相关操作(如物理引擎、动画等)会被停止,玩家无法进行任何互动。
- pause为falsepause为: 游戏恢复正常,时间流动恢复,游戏中的物理、动画、输入等都会继续。

Time.timeScale = 0;

UI.cs
更新部分!!!
功能分析:
GameManager.instance
是单例模式的GameManager
类的引用。GameManager
是用来管理游戏的核心类之一,它通常负责控制游戏的各种状态(如暂停、开始、游戏结束等)。- menu==inGameU
I
:_menu
代表当前菜单界面,inGameUI
是游戏内界面的标识。这个判断用于区分当前显示的是游戏内界面还是其他菜单界面。
作用:
- 如果当前显示的是
inGameUI
(即游戏界面),那么调用PauseGame(false)
,表示恢复游戏。 - 如果当前显示的不是
inGameUI
(即其他菜单界面),那么调用PauseGame(true)
,表示暂停游戏。
