Question

我一直在使用不同的Gesture Detector方法检测不同类型的输入。但是我想通过改变以下方法的参数来改变G.D的一些偏好：

public GestureDetector(float halfTapSquareSize,
                   float tapCountInterval,
                   float longPressDuration,
                   float maxFlingDelay,
                   GestureDetector.GestureListener listener)

我得到了http://libgdx.badlogicgames.com/nightlies/docs/api/com/badlogic/gdx/input/GestureDetector.html的代码

我对改变＆＃34; halfTapSquareSize＆＃34;

的价值特别感兴趣

我如何在下面的代码中实现它？

public class MyGdxGame extends ApplicationAdapter implements GestureDetector.GestureListener {

@Override
public void create() {
    super.create();
    //Doing stuff at create
}

@Override
public void resize(int width, int height) {
    super.resize(width, height);
}

@Override
public void render() {
    super.render();
    //Rendering stuff
}

@Override
public void pause() {
}

@Override
public void resume() {
}

@Override
public void dispose() {
    //disposing stufff
}

@Override
public boolean touchDown(float x, float y, int pointer, int button) {
    return false;
}

@Override
public boolean tap(float x, float y, int count, int button) {
    // Doing stuff at tap
    return true;
}

@Override
public boolean longPress(float x, float y) {
    return false;
}

@Override
public boolean fling(float velocityX, float velocityY, int button) {
    return false;
}

@Override
public boolean pan(float x, float y, float deltaX, float deltaY) {
    //Doing stuff when paning
}

@Override
public boolean panStop(float x, float y, int pointer, int button) {
    return false;
}

@Override
public boolean zoom(float initialDistance, float distance) {
    return false;
}

@Override
public boolean pinch(Vector2 initialPointer1, Vector2 initialPointer2, Vector2 pointer1, Vector2 pointer2) {
    return false;
}

}

您的代码仅实现了GestureListener。这个监听器需要与GestureDetector相关联，然后需要注册GestureDetector来处理输入。

所以在你的MyGdxGame课程中，你需要这样的东西： -

GestureDetector input = new GestureDetector(this); // 'this' refers to your MyGdxGame instance
Gdx.input.setInputProcessor(input);

现在您可以为GestureDetector的构造函数提供额外的参数，正如您在帖子中提到的那样，或者使用GestureDetector的相关方法，如下所示：

input.setTapSquareSize(someFloatValue);

在libGDX中构造一个GestureDetector
