HN discussionThink about many times a second you have to trace a shot. Now think about how many times a second you'd need to trace from every pixel on the screen to every part of the geometry on every opponent in order to check if it was visible or not to see if a player was legitimately able to view any part of their opponent. For example read this article someone else linked https://technology.riotgames.com/news/demolishing-wa…

HN discussion> Why do you think that? The server needs to at the very least trace a line for a shot. There is nothing difficult or slow about that. Before you say that it is done with a z-buffer or something similar, think about third person camera angles or how older games did the same thing. You might want to pull back on being so certain if you don't have experience with game engines or graphics. But... it is done with a z-bu…

HN discussionValorant specifically actually does this to a degree, and there was a quick article written by one of their anti-cheat developers that roughly explains their approach. https://technology.riotgames.com/news/demolishing-wallhacks-...

HN discussion> Don't disclose to the client anything not in their view. Either full of edges cases (how do you efficiently compute visibility, and can you prevent models from popping in as a result of latency) or computationally expensive[0]. Valorant, CSGO, League of Legends, Dota 2 are some of the games that I know about that implement server-side occluding to minimise the impact of wallhacks, but eventually a client will stil…

HN discussionRiot has a pretty good article about why it is hard: https://technology.riotgames.com/news/demolishing-wallhacks-... . Anything more than simple geometry makes server side calculations costly, especially when you're targeting 128 tick/s. Their settled solution is still not perfect, hence still the need for client-side anti-cheat. The final video clip is definitely done to look effective than it actually is. Those po…

HN discussionIn the end, games need to be built better by sending the least information needed to clients, ie. zero-trust. This is a big part of things like CS:GO, Valorant, and RTS games like starcraft/League/Dota since they can implement a 'fog of war' and only network information if their client actually needs it[0]. The only cheats that still plague Dota are scripts that perform tasks automatically, such as disabling an oppo…
