字符在JS中触摸后不会跳转

Question

我正在JS中为平台生成器编程冲突检测。出于某种原因，当我的角色接触到顶部的地面时，它不会再跳了。这是我的代码：

if (isCollideY(platforms[i].getBoundingClientRect(), document.getElementById('spriteNotReal').getBoundingClientRect()) == true) {
if (falling == true && (jumping == false)) {
moveY = platforms[i].getBoundingClientRect().y + 3;
momentumY = 0;
onSolidGround = true;
}
}

if (event.code == 'KeyW' && (moveY <= 300)) { 
moveY += 1;
move (moveX, moveY);
momentumY = momentumY + 20;
onSolidGround = false;
falling = false;
jumping = true;
}

else if (onSolidGround == false) {
if (momentumY < 0) {
falling = true;
}
else if (momentumY > 0) {
jumping = true;
}
else {
jumping = false;
}
moveX += momentumX / 3 + 1;
document.getElementById("spriteNotReal").src = "jumpmain.gif";
}

我的问题有点愚蠢。在检查了输入代码后，我意识到跳跃并没有发生，因为它只会在我设置测试的"平台"上跳跃，而不是在平台上。这是改进后的代码：

if (event.code == 'KeyW' && (onSolidGround == true)) { 
moveY += 1;
move (moveX, moveY);
momentumY = momentumY + 20;
onSolidGround = false;
falling = false;
jumping = true;
}
