Libgdx - 检查一个键是否被按住?
我正在使用 java libgdx 游戏库，我很好奇我是否可以判断一个键是否被按住，而不是按下并松开.
I'm using the java libgdx game library and im curious if I can tell if a key is being HELD, not pressed and let go.
我需要知道这一点，因为如果按下它，我将播放一个较短的 mp3 文件，如果按住它，我将播放一个较长的文件.
I need to know this because I'm going to play a shorter mp3 file if it is just pressed and a longer one if it is held.
推荐答案
是的，您可以通过 Gdx.input.isKeyPressed(Input.Keys.XXX) 或通过实现 InputProcessor.
Yes, you can easily check they either via Gdx.input.isKeyPressed(Input.Keys.XXX) or by implementing an InputProcessor.
public class MyInputProcessor implements InputProcessor {
public boolean keyPressed;
@Override
public boolean keyDown(int keycode) {
if (keycode == Input.Keys.XXX) {
keyPressed = true;
}
return false;
}
@Override
public boolean keyUp(int keycode) {
if (keycode == Input.Keys.XXX) {
keyPressed = false;
}
return false;
}
}
并像这样使用它:
MyInputProcessor processor = new MyInputProcessor();
Gdx.input.setInputProcessor(processor);
...
if (processor.keyPressed) {
// do some stuff
}
