我有一個矩形,我想以恆定的速度向上移動屏幕,並對我的代碼爲什麼不工作感到困惑。以下是代碼:向上移動屏幕上的矩形
package com.ashmore.MyGame;
import java.util.ArrayList;
import java.util.List;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Rect;

import com.ashmore.framework.Game;
import com.ashmore.framework.Graphics;
import com.ashmore.framework.Image;
import com.ashmore.framework.Screen;
import com.ashmore.framework.Input.TouchEvent;
public class GameScreen extends Screen {
enum GameState {
Ready, Running, Paused
}
GameState state = GameState.Ready;
boolean BarisMoving = false;
private ArrayList<Rect> rectangles = new ArrayList<Rect>();
int bar_x = 32;
int bar_y = 653;
int bar_width = 183;
int bar_height = 648;
Rect bar;
Paint paint;
public GameScreen(Game game) {
super(game);
// Initialize game objects here
bar = new Rect();
bar.set(bar_x, bar_y, bar_width, bar_height);
// Defining a paint object
paint = new Paint();
paint.setTextSize(30);
paint.setTextAlign(Paint.Align.CENTER);
paint.setAntiAlias(true);
paint.setColor(Color.WHITE);
}
private void updateRunning(List<TouchEvent> touchEvents, float deltaTime) {
// 1. All touch input is handled here:
int len = touchEvents.size();
for (int i = 0; i < len; i++) {
TouchEvent event = touchEvents.get(i);
BarisMoving = true;
if (event.type == TouchEvent.TOUCH_UP) {
if (ScalesScreen.scaleType.equals("C")) {
rectangles.add(new Rect(56, 400, 80, 435));
//rectangles.get(0);
break;
}
if (BarisMoving) {
bar_y = bar_y -= 10;
}
for (Rect rect : rectangles) {
if(bar.intersect(rect)) {
checkButtons();
}
}
}
}
private void checkButtons() {
Log.d("GameScreen","Note and Bar Intersected");
}
@Override
public void paint(float deltaTime) {
Graphics g = game.getGraphics();
Paint paint = new Paint();
Paint paint2 = new Paint();
paint.setColor(Color.RED);
paint2.setColor(Color.RED);
for (Rect rect : rectangles) {
g.drawRect(rect, paint);
}
g.drawRect(bar, paint2);
}
private boolean inBounds(TouchEvent event, int x, int y, int width,
int height) {
if (event.x > x && event.x < x + width - 1 && event.y > y
&& event.y < y + height - 1)
return true;
else
return false;
}
}
我可能錯過了一些非常基本的東西。但是,我似乎無法找到問題。任何幫助表示讚賞!
「不工作」有點含糊。如果你告訴我們發生了什麼,你會得到更快的答案。 – christutty
我想把屏幕上的矩形條移動到屏幕上,但它並沒有向上移動這個代碼 – user2712795
它與你的問題無關,但不應該「bar_y = bar_y - = 10;」只是「bar_y - = 10;」 ? – christutty
