Unity | 常用动态UI_Demo(附源码)_unity demo源码

☀️前言介绍 

为了增加制作UI及其动态效果的熟练度，前两天就修仙游戏题材，使用Unity+VsCode搞了个小Demo，主要涉及：

❥ 滚动矩形 (Scroll Rect)

❥ 输入字段 (Input Field)

❥ 滚动条 (Scrollbar)

❥ 开关组 (Toggle Group)

❥ 按钮 (Button)

❥ 自动布局 (Layout)

❥ 可视组件 (visual Component)

❥ 红点系统 (Redpoint)

...

 ☀️Demo效果呈现

录屏用了MS商店自带的ScreenToGif转了格式，流畅度和颜色效果变得有点差

☀️具体流程回顾

有关最基础的滑动列表的制作（好看点的主要是在代码中动态获取了加入的美术资源），我们在 UI-Window 下新建一个 sv 挂上 滚动矩形 (Scroll Rect)，再挂上我们的 content 即可，蓝色框表示滚动方式，按照一般标准的手机分辨率，我们只勾选垂直（Vertical）方式。

在 sv 下的 Viewport上，挂载上我们的 mask，确保我们鼠标点击/移动的区域

最后在我们的 content 上挂载自动布局方式：垂直布局组 (Vertical Layout Group)

test_item的inspector面板（Unity3D属性监视面板 (Inspector) Unity3D属性监视面板中的属性允许用户在代码外部改变脚本及组件的初始值。）

简单 lua 滑动列表的实现效果如下：

点击我们的 btn_add 按钮可以生成可供滑动的列表元素，这些元素的属性和数据可以通过 local datas = { } 来获取，我们可以在里面给每个小的横向列表附值，并且通过 function( ) .. end, 反馈 btn_add 按钮的点击事件。这是比较好的一种方法，就是将我们的 local datas = { } 写进我们的 on_clicked_btn_add(btn) 来一键生成多个列表元素。

其他的后续补充ing ...
