Question

除了事实上即使这个人输掉了比赛，得分也在不断计算，所以一切都应该完美无缺。当游戏丢失时，分数应该冻结，以便当方法gameover（）;被称为该游戏的分数。

它也没有增加一个特定的数量，分数从10增加到210到430 - 它只是到处都是。有人能找到原因吗？

Answer 1

你应该有 playing = false;
在游戏方法或其他地方的某个地方。正如我所见，你没有这样的代码。我问一个问题。你把哪里改成了假，所以你希望得到

 If(!playing)

条件而不是

If(playing)

你按下键。游戏开始了。现在你到达

If(playing)

然后球到达边界并且代码到达

 if ( ballX > width || ballX < 0 ) {
gameover = true; } // if the ball reaches one of the bounderies it will be game over

在这种情况下。播放var和gameover var都是正确的。对？

下

If(playing)

你有得分（）方法。即使游戏结果为真，仍然会执行得分方法。

您可以在以下情况下将播放设置为false：

if ( ballX > width || ballX < 0 ) {     gameover = true;
Playing =false ; }

或者您可以像这样修改得分方法：

 void score () { if (playing && !gameover) { fill(255); textSize(45); textAlign(CENTER); text(scorecounter, width/2,height/4); 
// keeps the score on the display  while playing }

比赛结束后为什么得分仍在计算？
