Valve 是如何在《军团要塞 2》中构建实时成就引擎的？
当我在 Steam 上玩《军团要塞 2》时，我注意到成就的复杂性令人惊叹。
是否有任何资源描述他们如何构建成就引擎？必须同时实时处理大量数据才能检测是否符合成就标准。我不认为它使用了“复杂事件处理”等熟悉的概念。
The complexity of achievements I've noticed while playing Team Fortress 2 on Steam is amazing.
Are there any resources that describe how they architected their achievement engine? There is a lot of data that has to be processed simultaneously and in real-time to detect a match for the criteria of the achievements. I don't feel it uses familiar concepts such as 'Complex Event Processing'.

这是一个有趣的问题。我也找不到任何关于它的帖子。
但 Values 游戏都是通过 Steam/VAC 验证的，因此在一定程度上他们可以在客户端进行更多的自由操作。我假设他们在客户端完成所有检测并将结果发送到服务器。
据我所知，所有成就都不会太复杂，不会在足以玩《军团要塞》的机器上造成帧速率发生任何明显变化。投射物和其他“玩家创建的效果”很可能都与创建它们的玩家或玩家成就数据库有连接，以便在创建后立即注册其所有数据。
Its an interesting question. I couldn't find anything posted about it either.
But Values game are all verified via Steam/VAC so to a certain extent they can take more liberties with what they do on the client side. I would assume they do all the detection client side and just send the results up to the server.
None of the achievements I know of are too complex to cause any noticeable change in frame rate on a machine that is strong enough to play Team Fortess. Projectiles and other 'player created effects most likely all have a connection back to the player that created them, or the players achievement database to register all their data as soon as it is created.
