Anti-cheat built on Minecraft's own physics.

Counter works out where every player should be each tick, the same way the vanilla client does. Anything a normal client can't do gets flagged.

How it works

Counter runs the movement code itself. Friction, gravity, water, lava, ladders, ice, slime, elytra, boats and potion effects all go into the math.

When a move doesn't match, it knows by how much. That lets it be strict with cheaters and still go easy on players with bad ping.
