javascript - JS中触摸后角色不会跳跃

Question

我正在用 JS 为平台游戏编写碰撞检测。由于某种原因，当我的 Angular 色顶部接触地面时，它不会再次跳跃。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。检查输入代码后，我意识到跳转没有发生，因为它只会在我设置测试的“平台”上跳转，而不是在实际在平台上时跳转。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;
        }
