Input 使用输入处理器触地事件检测对象触碰
我想在一个触摸硬币的物体上收集硬币。所以我喜欢这个Input 使用输入处理器触地事件检测对象触碰,input,libgdx,touch,Input,Libgdx,Touch,我想在一个触摸硬币的物体上收集硬币。所以我喜欢这个 if (Gdx.input.justTouched()) { touchPos.set(Gdx.input.getX(), Gdx.input.getY(), 0); game.camera.unproject(touchPos); for (int i = 0; i < coins.length; i++) { Rectangle textureBounds =

在gameScreen类中
MyInputProcessor myInputProcessor = new MyInputProcessor();
InputMultiplexer im = myInputProcessor.returnInput(stage);
Gdx.input.setInputProcessor(im);
但我不知道如何在输入处理器触地事件中获得这个触碰位置。您的
MyInputProcessor
应该是这样的
if (Gdx.input.justTouched()) {
touchPos.set(Gdx.input.getX(), Gdx.input.getY(), 0);
game.camera.unproject(touchPos);
for (int i = 0; i < coins.length; i++) {

//after touch something happens
}

为什么
GestureDetector
,你在使用它?不。我目前没有使用它。包含了有问题的完整类。@Abhishekaryan如果(Gdx.input.justtouch()){}编写代码时,类的名称是什么?它在gameScreen类中,我把所有的游戏逻辑放在那里。在更新(float delta)中调用justtouch().code已编辑。@Abhishekaryan谢谢您的帮助!它工作起来没有什么变化。没有包括Gdx.input.setInputProcessor(新的MyInputProcessor(这个))并且只在游戏屏幕上保留了硬币相关的东西。如果你想检测舞台上的触摸,你需要将舞台添加为inputprocessor,我已经编辑了我的答案,请检查
