True, can’t think of how would you combat a cleverly written aim-bot.

Don’t tell the client what’s going on outside its vision, I suppose? Add a small buffer to compensate for latency, so wall hack would be more of a “corner hack”.

I imagine the alternative way to combat kernel-level cheats would be asking player for all his game state data, validating it on a server?

Wouldn’t work on peer-to-peer and you’d have to do a bunch of unnecessary compute(recalculating every tick if player-generated data is possible according to game rules) but its the only way I can think of.

You folks are living in the stone age. In the current millennium, plenty of consumer-grade pre-built planets are available.

All you have to do is occasionally spend your weekend debugging incompatibility of gravity and quantum layers.
