Toggle Group

A Toggle Group is not a visible UI control but rather a way to modify the behavior of a set of Toggles. Toggles that belong to the same group are constrained so that only one of them can switched on at a time - pressing one of them to switch it on automatically switches the others off.

开关切换组是不可见的 UI 控件而是在要修改的行为切换的一组（就是单选按钮）。属 于同一组的切换约束这样，只有一个人可以选择在时间-选择其中之一时将自动取消所有其 他选择。

A Toggle Group

Properties

Description

The Toggle Group is setup by dragging the Toggle Group object to the Group property of each of the Toggles in the group.

Toggle Groups are useful anywhere the user must make a choice from a mutually exclusive set of options. Common examples include selecting player character types, speed settings (slow, medium, fast, etc), preset colors and days of the week. You can have more than one Toggle Group object in the scene at a time, so you can create several separate groups if necessary.

Unlike other UI elements, an object with a Toggle Group component does not need to be a child of a Canvas object, although the Toggles themselves still do.

Note that the Toggle Group will not enforce its constraint right away if multiple toggles in the group are switched on when the scene is loaded or when the group is instantiated. Only when a new toggle is swicthed on are the others switched off. This means it’s up to you to ensure that only one toggle is switched on from the beginning.

不同于其他 UI 元素，具有一个切换组组件的对象不需要是画布对象的一个孩子，虽然 Toggles 自己是。要向 group 组中添加 Toggles，可以简单地将 group 组对象拖动到 Toggles 切 换的 group属性在检查器 inspector 中。你可以有一个以上切换组对象在场景中在一段时间， 所以如果有必要，您可以创建几个单独的组。 Toggle Groups 切换组应用在任何地方， 用户必须作出一个选择从一组互斥的选项中。 常见的例子包括选择玩家性别类型、 速度设置 （慢，中等，速度快，等）、 预设的颜色和 星期几。
