SamPlay · **info request on HL1 engine -** 09-06-2006

Can anyone be so kind as to tell me where I can find info on how the engine updates the various players ( I cannot understand why my bot in god mode cannot get a headshot anytime I want it, in conditions where the weapon accuracy is of no concern).
eg: does the other players moves while your own Startframe code is running? ( do their position vary, which would require for shooting to pick their position
the latest possible before calling pfnrunplayermove)? or is everything frozen ?
Do we need to do some prediction on the other players moves , does the engine compensates in some way?
I am ready to spend some time looking through the code of another publicly available engine ( like Quake 1/ 2/ 3) but I do not know if it is relevant for HL1.

Or any paper/website/..., even not HL1 specific, explaining how an engine deals with multiplayers updates, would also be of interest.
Thanks in advance.
