onValueChanged在用户单击了下拉列表中一个选项时调用的 UnityEvent。 options可能选项的列表。可以为每个选项指定一个文本字符串和一个图像。 template下拉列表的模板的矩形变换。 value该值是 Dropdown 中当前选择内容的索引号。0 代表 Dropdown 中的第一个选项,1 代表第二个,依此类推。
下面的DropdownEx类在Dropdown基础上,增加一个m_AlwaysCallback 变量,勾选后每次点击都会触发回调 usingSystem;usingSystem.Collections;usingSystem.Collections.Generic;usingUnityEngine.Events;usingUnityEngine.EventSystems;usingUnityEngine.UI.CoroutineTween;usingUnityEngine.UI;usingUnityEngine;publicclassDropdownEx :...

AddOptions基于 OptionData 对象的列表将多个选项添加到 Dropdown 的选项。 ClearOptions清除 Dropdown 中的选项列表。 Hide隐藏下拉列表。 OnCancel在取消事件发生时由 BaseInputModule 调用。 OnPointerClick“单击”下拉列表时的处理。 OnSubmit在事件系统发送提交事件时要执行的操作。
Recently I've been working with Unity UI, and its event system. This system is seemingly user-friendly in the sense that components have event fields where we put scripts that will do the work. This is already off-standard (bad practice): the GUI button should not be bound to the...
