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？

答案 0 :(得分：0)
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 }
