由于许多布尔检查我有点困惑,让我向我介绍下一个代码。
} else {
//check whether the player starts again. the first time we lose the player
//will definitely get into this loop
if(!startAgain){
// we only do this to set a timer, we don't want to start a new game so we set this
// to false
newgame = false;
startAgain = true;
deadTime = System.nanoTime();
}
deadTimepassed = (System.nanoTime() - deadTime)/1000000;
if((deadTimepassed < 2000) && (newgame = false)){
newGame();
}
}
}
这个其他声明可以看作是玩家第一次被敌人的导弹击中。制作爆炸动画。我需要te屏幕冻结2秒钟,然后重新开始游戏。我不明白为什么永远不会达到第二个if语句。这是我的ontouch方法和我的新游戏方法:
@Override
public boolean onTouchEvent(MotionEvent event) {
//What happens when the player touches the screen!
if (event.getAction() == MotionEvent.ACTION_DOWN) {
// Boolean check for when player is playing, if he isn't the chopper does nothing.
// we see that the chopper only hangs still if all these booleans are true!
if ((!player.isPlaying()) && (newgame = true) && (startAgain = true)) {
player.setPlaying(true);
} if(player.isPlaying()) {
player.setUp(true);
startAgain = false;
}
return true;
}
if (event.getAction() == MotionEvent.ACTION_UP) {
player.setUp(false);
return true;
}
return super.onTouchEvent(event);
}
public void newGame(){
newgame = true;
missles.clear();
if(player.getScore()>best) {
best = player.getScore();
SharedPreferences.Editor editor = saveBest.edit();
editor.putInt("new best",best);
editor.commit();
}
player.resetScore();
player.setY(HEIGHT/2);
}
正如人们所看到的,新游戏只是重置了玩家的位置,我唯一要做的就是在此之前将屏幕冻结2秒钟,这应该发生在第二个if语句中,但它永远不会得到达到...
有什么建议吗?
ps:deadTimepassed被引入为&#39; private long&#39;就在公共类方法之下。
答案 0 :(得分:0)
要冻结您的Thread
(因此,程序将冻结,也会冻结您的屏幕),您可以在2秒内使用Thread.sleep()
功能:
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
您必须将其放在try-catch
块中,因为它可以为您提供InterruptedException
。
我希望它会对你有所帮助!
