Introduction Hi, I’m Glenn Fiedler and welcome to Building a Game Network Protocol. In the previous article, we created a bitpacker but it required manual checking to make sure reading a packet from the network is safe. This is a real problem because the stakes are particularly high - a single missed check creates a vulnerability that an attacker can use to crash your server. In this article, we’re going to transform the bitpacker into a system where this checking is automatic.| Gaffer On Games
