This class will have the same purpose as the class of the same name did in the previous project. It will also look very similar too.
Add a new class called UIController and add the member variables, constructor and addObserver method.
import android.graphics.Point;
import android.graphics.Rect;
import android.view.MotionEvent;
import java.util.ArrayList;
class UIController implements InputObserver {
private float mThird;
private boolean initialPress = false;
UIController(GameEngineBroadcaster b, Point size) {
// Add as an observer
addObserver(b);
mThird = size.x / 3;
}
void addObserver(GameEngineBroadcaster b) {
b.addObserver(this);
}
}The float mThird variable will help us to divide the screen up vertically into thirds. The player will then be able to tap a portion of the screen to choose the level that they want to play. The initialPress Boolean is used in a workaround to avoid a bug/glitch...
