我有一个RectList的ArrayList，它由x，y，x2，y2值定义，另一个Rect在屏幕上移动，应该与ArrayList中的矩形相交。但是，当矩形相交时，什么也没发生。以下是我的相关代码：
public static ArrayList<Rect> rectangles = new ArrayList<Rect>(100);
public static ArrayList<Rect> rectangles2 = new ArrayList<Rect>(90);
public static Rect intersected = new Rect();
int bar_x = 32;
int bar_y = 653;
int bar_x2 = 183;
int bar_y2 = 648;
int BarSpeed = 2;
Rect bar;
Paint paint;
public GameScreen(Game game) {
super(game);
// Initialize game objects here
bar = new Rect();
bar.set(bar_x, bar_y, bar_x2, bar_y2);
rectangles.add(new Rect(135,614,160,588));
rectangles.add(new Rect(124,541,147,512));
for (Rect rect : rectangles) {
if(Rect.intersects(bar, rect)) {
Log.d("GameScreen", "intersected");
intersected = rect;
checkButtons();
}
}
if (BarisMoving) {
bar_y -= BarSpeed;
bar_y2 -=BarSpeed;
bar.set(bar_x, bar_y, bar_x2, bar_y2);
}
}
private void checkButtons() {
Log.d("GameScreen","Note and Bar Intersected");
KeyButton keybutton = new KeyButton();
if (B1Pressed == keybutton.getB1() && B2Pressed == keybutton.getB2() && B3Pressed == keybutton.getB3()) {
Log.i("GameScreenTest", "Correct");
score++;
} else {
Log.i("GameScreenTest - Result", "Wrong");
Log.i("GameScreenTest - Button Pressed", Boolean.toString(B1Pressed));
Log.i("GameScreenTest - Button Required", Boolean.toString(keybutton.getB1()));
}
}
在我的LOGCAT中，没有写入“相交”。我怎样才能使矩形相交？
