我正在尝试制作在线游戏。服务器发送周围＆＃34;块的数据＆＃34;到客户端，然后保存块，并在绘制时检查这些块的已保存数据并绘制它们。因此，绘制的数据将保存在客户端的Array上。即使数据保存在该阵列上，如果我使用ip连接到服务器，图形似乎闪烁，但当连接作为本地主机时，图形就好了。我也尝试过使用双缓冲（当使用localhost运行时它也可以正常工作而没有双缓冲区）但是当使用ip时它仍然闪烁（即使我使用双缓冲（不太确定它是否正常工作）虽然..））所以我要问的是：
1）为什么在使用ip而不是localhost时它会闪烁？ （它不能因为插座上的流量过大而导致）
2）我怎样才能做更好的双缓冲（我已经使用了youtube和互联网的多个指南，如this） 到目前为止，我使用过的导游都没有帮助避免闪烁..
