碰撞檢測不註冊球

Question

嗨我想做一個簡單的pong遊戲，我遇到了碰撞檢測的麻煩。球沒有登記槳。

function moveBall() { 
    var rightRadius = ballX + radius; 
    var leftRadius = ballX -radius; 

    if (ballX + radius > canvas.width || ballX - radius < 0) { 
     ballOffX = -ballOffX; 
    } 
    /* 
    The following code is handling the collision of the ball with the plate 
    */ 
    if((rightRadius <= (player1.x + paddleWidth))&&(leftRadius >= player1.x) &&(player1.y == ballY + 10)){ 
     ballOffY = -ballOffY; 
    } 

    ballX += ballOffX; 
    ballY += ballOffY; 

}

我做了一個if語句來檢測在JavaScript中的碰撞，那就是：

if circle x < rect x + circle width && circle x + rect width > rect x && circle y < rect y + circle height && rect height + circle y > rect y { 

這部作品通過把球內的「虛構的盒子」，並在任何的'虛擬盒子'的邊緣碰到矩形的任何邊緣，就會檢測到碰撞。
