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
这样的东西 <IfModule mod_rewrite.c>
