java - 添加对话框时 libgdx 崩溃

Question

嗯，我遇到了问题

我已经开始使用 libgdx 编写我的第一个游戏并创建了菜单 我正在尝试为“关于”按钮提供一个打开文本对话框的功能

但是当我添加代码时，游戏在运行时崩溃

谁能给我链接到制作文本对话框的指南吗？

因为我发现的一切都不适合我......

我找到并使用的代码:

new Dialog("Dialog", skin, "dialog") {
   protected void result (Object object) {

   }
}.text("texttexttext").button("Yes", true).button("No", false).key(Keys.ENTER, true)
   .key(Keys.ESCAPE, false).show(stage);

Answer 1

根据您的代码和异常:

No com.badlogic.gdx.scenes.scene2d.ui.Window$WindowStyle registered with name: dialog

您的 Skin.json 文件中需要有一个名为“dialog”的 WindowStyle:

com.badlogic.gdx.scenes.scene2d.ui.Window$WindowStyle:
{
 dialog: { titleFont: <your-font>, titleFontColor: <your-font-color (optional)>, background: <your-background-drawable (optional)>},
}
