LIBGDX Touch Event resolution

1. How to get the stage to accept touch events:

Register Listener

Inputmultiplexer inputmultiplexer = new Inputmultiplexer (Getstage (), new Gesturedetector (this));

Gdx.input.setInputProcessor (Inputmultiplexer);

The second one here is for gesture monitoring. (Slide, zoom, etc.)

2. Here is a special note that all events are processed before they are drawn.

Gdx.input.justTouched ()

Gdx.input. Istouched ()

The above two methods are used to get the screen whether there is a click (Touchdown action).

It's not a good idea to switch between screens if you want to use the above method.

if (Gdx.input.justTouched ()) {

If The screen was touched, go to the next screen

}

When you switch to the second screen, the second screen accepts the Touchup event, and if some variables involve touchdown processing, an error occurs.

The reasons are as follows:

The first screen processing down event, switch Screen,screen registers the event receiver for drawing processing--now that the second screens are displayed, the up event is processed.

an event, starting in touchdown, and finally touchup!

PS: If you want to switch screen by clicking, you can do it by clicking on a control, such as image.

Image screenbg .... Background layer, consistent with screen size

Screenbg.addlistener (New Inputlistener () {

@Override

public boolean TouchDown (InputEvent event, float x, float y, int pointer, int button) {

The Touchup event is triggered only if true is returned.

return true;

}

@Override

public void TouchUp (InputEvent event, float x, float y, int pointer, int button) {

if (conditional trigger) {

Chgame.getinstance (). Setscreen (Nextscreen);

}

}

});
