Question

我试图让一个球从一个矩形桨的边缘反弹，到目前为止我做的是让球从桨的顶部边缘反弹。但是每当球接触到任何一侧（右侧或左侧）时，它就会卡在桨内，并且不会反弹。

为了让球从桨的顶部反弹，我使用了下面的直接代码：

// bounce ball off paddle
        if (object == paddle)
        {
                velocityY = -velocityY;
        }

任何人都可以帮助我增强此代码，以便它可以检测到球是否触及了球拍的右侧或左侧，并使其反弹。

请注意，我正在使用C。

谢谢，

就像你对Y轴所做的那样，在碰撞设置之后

$httpProvider.interceptors.push(function ($q, $injector) {
    var incrementalTimeout = 1000;

    function retryRequest (httpConfig) {
        var $timeout = $injector.get('$timeout');
        var thisTimeout = incrementalTimeout;
        incrementalTimeout *= 2;
        return $timeout(function() {
            var $http = $injector.get('$http');
            return $http(httpConfig);
        }, thisTimeout);
    };

    return {
        responseError: function (response) {
            if (response.status === 500) {
                if (incrementalTimeout < 5000) {
                    return retryRequest(response.config);
                }
                else {
                    alert('The remote server seems to be busy at the moment. Please try again in 5 minutes');
                }
            }
            else {
                incrementalTimeout = 1000;
            }
            return $q.reject(response);
        }
    };
});

如果你想要一些东西＆＃34;更精致＆＃34;你可以尝试制作像
