?前言
- IMGUI不会用作游戏的UI开发
- 会用到游戏的编辑器开发
?️ 题单来自:唐老狮
?(A)IMGUI工作原理
?(B)IMGUI——基本控件
- GUIContent -----可以是以下三者的结合
tooltip–鼠标选中后课得到该信息(作为隐藏信息使用) - GUIStyle ———全部综合
1.Nomal ——正常情况
2.Hover——鼠标停留后
3.Active——按下之后
?(C)IMGUI基本控件—文本控件
?(D)IMGUI基本控件—按钮控件
- 点击的逻辑情况 ——> GUI.Button == true ;
(在原地方点击后松开才算一次点击)
练习操作
- 用GUI制作一个游戏开始界面,上面有开始游戏,退出游戏,设置等等按钮选项,点击开始游戏可以切换到游戏场景

if (GUI.Button(RectButton1, "开始游戏", button1))
{
SceneManager.LoadScene("simple1");
}
GUI.Button(RectButton2,"设置", button2);
GUI.Button(RectButton3, "退出游戏",button3);
//------------游戏设置面板--------------
}
}
?(E)IMGUI基本控件—多选框和单选框
