Server-rendered multiplayer games with Lua (no client code)

The way they did it, they were writing an aimbot. So the pipeline was:

- take a screenshot

- run massive skeletal detection on it to get the skeletons of any humanoids

- of those skeletons, pick a target closest to the player

- for that target, get coordinates of head node

- run a PID to control the cursor to where the head node is located

- move the camera one frame, repeat the whole process. If you can fit that pipeline to 16ms it can run in real time.

Wow, that's fascinating. Were they able to fit the whole thing inside the 16ms frame?

oh yeah, with little problem, especially with a GPU it's not hard at all.
