在 libgdx 中，如何从后退按钮获取输入? [英] In libgdx, how do I get input from the back button?

问题描述

对于我的游戏，我希望 Android 后退按钮将您带到暂停菜单，而不是最小化游戏.根据我的谷歌搜索，我知道我需要打电话

For my game, I'd like the Android back button to take you to the pause menu, instead of minimizing the game. From what I've googled, I know I need to call

Gdx.input.setCatchBackKey(true);

但我如何实际检查按钮是否按下?input.isKeyDown(Keys.BACK) 似乎什么也没做.

But how do I actually check for the button press? input.isKeyDown(Keys.BACK) doesn't seem to do anything.

推荐答案

我是这样解决问题的:

public class MyApplication implements ApplicationListener, InputProcessor {
   // !! Remember to override all other required methods !!
   ...

   @Override
   public void create() {
        Gdx.input.setInputProcessor(this);
        Gdx.input.setCatchBackKey(true);
        // rest of your stuff...
   }

   ...

   @Override
   public boolean keyDown(int keycode) {
        if(keycode == Keys.BACK){
           // Do your optional back button handling (show pause menu?)
        }
        return false;
   }

   ...
}

不是copypasta的东西，但希望这可以帮助你.:)
