Я использую canvas.translate, чтобы изменить coodinates моего холста, чтобы область просмотра изменила
мой код:
public class draw extends View {
View v;
Paint paint;
int width;
int height;
int view_x;
int view_y;
static final int MAX_GAME_SPEED = 25;
static int fps;
public draw(Context context) {
super(context);
// tb.loadimg();
Thread myThread = new Thread(new UpdateThread());
myThread.start();
}
@Override
protected void onDraw(Canvas c) {
super.onDraw(c);
paint = new Paint(); // Paint paint = new Paint();
paint.setStyle(Paint.Style.FILL);
// get screen size
WindowManager wm = (WindowManager) this.getContext().getSystemService(
Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
width = display.getWidth(); // deprecated
height = display.getHeight(); // deprecated
// make the entire canvas white
paint.setColor(Color.WHITE);
c.drawPaint(paint);
if (tb.dirt != null && tb.stone != null && tb.sand != null
&& tb.gold != null && tb.iron != null && tb.coal != null
&& tb.kies != null && tb.diamond != null && tb.redstone != null
&& tb.lava != null && tb.azur != null && tb.water != null) {
c.drawBitmap(tb.dirt, 0, 0, paint);
c.drawBitmap(tb.stone, 0, 50, paint);
c.drawBitmap(tb.sand, 0, 100, paint);
c.drawBitmap(tb.gold, 0, 150, paint);
c.drawBitmap(tb.iron, 50, 0, paint);
c.drawBitmap(tb.coal, 50, 50, paint);
c.drawBitmap(tb.kies, 50, 100, paint);
c.drawBitmap(tb.diamond, 50, 150, paint);
c.drawBitmap(tb.redstone, 100, 0, paint);
c.drawBitmap(tb.lava, 100, 50, paint);
c.drawBitmap(tb.azur, 100, 100, paint);
c.drawBitmap(tb.water, 100, 150, paint);
}
if (tb.map == null) {
}
view_x = 100;
view_y = 100;
c.translate(0, -4);
}
public Handler updateHandler = new Handler() {
/** Gets called on every message that is received */
// @Override
public void handleMessage(Message msg) {
invalidate();
super.handleMessage(msg);
}
};
public class UpdateThread implements Runnable {
@Override
public void run() {
while (true) { // Game Loop
long startTime = System.currentTimeMillis();
draw.this.updateHandler.sendEmptyMessage(0); // veranlassen,
// dass paint()
// erneut
// aufgerufen
// werden soll
// for (int i=0; i<999999; i++); //Bremse
Thread.yield();
long executionTime = System.currentTimeMillis() - startTime;
if (executionTime < MAX_GAME_SPEED) {
try {
Thread.sleep(MAX_GAME_SPEED - (int) executionTime);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
fps = 1000 / MAX_GAME_SPEED;
} else
fps = (int) (1000 / executionTime);
}
}
}
}
, но просто ничего не происходит, я видел много онлайн примеров, ноЯ просто не понимаю мою проблему -.-
