单击时使角色向上移动

Question

我正在制作类似Flappy Bird的游戏。单击浏览器窗口时，该字符应向上移动，但我的代码不起作用。以下是相关的代码行：

var dudeYSpeed = 0;
var dudeXSpeed = 0;
var dudeJumping = false;
var jumpSpeed = -3;

if (mouseDown && dudeJumping === false){
    dudeJumping = true;
    dudeYSpeed = jumpSpeed;
} 
else {
    translateY += dudeYSpeed;
    dudeYSpeed += gravity;
    dudeJumping = false;
} 

translateX += dudeXSpeed;

Answer 1

如果translateY为真，您只会更新dudeYSpeed和dudeJumping。无论输入是什么，您都应该在每一帧中更新这些变量。
