暫停屏幕畫布不更新

Question

通過單擊空格可以獲得暫停屏幕。我試圖更新分數，但我認爲如果其他循環錯誤，我沒有收到任何錯誤。 只需點擊此處，一邊玩打空間： http://www.taffatech.com/Snake.html 的代碼，很麻煩，我認爲是：

function SetSize() 
{ 
if (document.getElementById('Easy').checked) 
{ 
cellSize = 10; 
Mode = 1; 
} 

else if (document.getElementById('Medium').checked) 
{ 
cellSize = 20; 
Mode = 2; 
} 

else if (document.getElementById('Hard').checked) 
{ 
cellSize = 30; 
Mode = 3; 
} 
} 

function init() 
{ 


if (Mode == 1) 
{ 
scoreEasy = easyScore; 
if(score > scoreEasy) { 

easyScore = scoreEasy; 

} 
} 

else if (Mode == 2) 
{ 
scoreMedium = mediumScore; 
if(score > scoreMedium) { 

mediumScore = score; 

} 
} 

else if (Mode == 3) 
{ 
scoreHard = hardScore; 
if(score > scoreHard) { 

highScore = score; 

} 
} 

Answer 1

我猜這裏

scoreHard = hardScore; 
if(score > scoreHard) { 

如果是這樣：

scoreHard = Math.max(score,hardScore); 

還highScore = score;在hardScore部分，不應該是hardScore = score;？
