我的碰撞检测不工作

Question

所以我正在制作一款Pong游戏作为编程练习。其他一切似乎都有效，但碰撞检测无论如何都不起作用，因为球像幽灵一样飞过桨。

player.top = player.y;
player.right = player.x + player.width; 
player.bottom = player.y + player.height; 
player.left = player.x;
ball.top = ball.y - ball.radius; 
ball.right = ball.x + ball.radius; 
ball.bottom = ball.y + ball.radius; 
ball.left - ball.x - ball.radius; 
return ball.left < player.right && ball.top < player.bottom && ball.right > player.left && ball.bottom > player.top;
}

let player = (ball.x < canvas.width / 2) ? playerOne : playerTwo; // where i'm calling the collision detection function in update

if (collisionDetection(player, ball)){ 
let angle = 0; 
if (ball.y < (player.y + player.height / 2)){
angle = -1 * Math.PI / 4;
}
else if (ball.y > (player.y + player.height / 2)){ 
angle = Math.PI / 4;
}
ball.velocityX = (player === playerOne ? 1 : -1) * ball.speed * Math.cos(angle);
ball.velocityY = ball.speed * Math.sin(angle);
ball.speed += 0.22;
}

我不确定是我做错了数学，还是我错误地使用了玩家变量，但无论如何它都无法工作。

Answer 1

我不太确定，但我认为你的

return ball.left < player.right &&
ball.top < player.bottom &&
ball.right > player.left &&
ball.bottom > player.top;

不是检查碰撞，而是检查球是否完全在球员内部。
