【问题描述】:
我想每秒更改一次气球的位置(随机)。我写了这段代码:
public void render() {
int initialDelay = 1000; // start after 1 seconds
int period = 1000; // repeat every 1 seconds
Timer timer = new Timer();
TimerTask task = new TimerTask() {
public void run() {
rand_x = (r.nextInt(1840));
rand_y = (r.nextInt(1000));
balloon.x = rand_x;
balloon.y = rand_y;
System.out.println("deneme");
}
};
timer.schedule(task, initialDelay, period);
Gdx.gl.glClearColor(56, 143, 189, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
camera.update();
batch.setProjectionMatrix(camera.combined);
batch.begin();
batch.draw(balloon, balloon_rec.x, balloon_rec.y);
batch.end();
}
initialDelay 正在工作。当我运行程序时,气球的位置在 1 秒后发生变化。但是期间不起作用。问题出在哪里?
