Quake 3 Collision Detection

Post by **aziraphale** » Thu Jul 19, 2007 11:10 pm

This may sound like a really silly question, but....does q3 have some collision detection problems?

reason im asking is, im using 1.16n, but want to move to 1.32. before i do, i want to know if my game half-decent or not. troible is, with 1.16n, i think a lot of my shots should frag or at least damage, but they dont.

example, and most obvious is rocketry. i can fire a rocket at someone running straight for me. it will hit the floor/wall behind them, when they have run past it in "transit". trouble is, my opponent will have appeared to run right through said rocket.

my first thought was, f**K, is it possible for a rocket to go between a character's legs? cant be, as the hitbox stays the same, and splash damage can be caused by landing a rocket at someone's feet.

how is it possible that this appears? i have decent spec comp, good connection/ping, reasonable config.....anyone any thoughts?

Sounds like packet loss. Perhaps one of the configuration experts can help you out.

Yeah, or just plain lag. It takes packets a while to get from your PC to the server and vice versa, so what you see is always slightly out of touch with what the server sees. What's your in-game ping and how stable is it?

my ping depends, when i first srted playing i had a ping or around 18-20, now it seems to be 33-40, but my router does disconnect sometimes. (wireless)
would the router be causing the problem, you think?

I assume you're on Windows? XP or Vista? What kind of router and wireless card do you have?

Try pinging your router and look for spikes in the connection. Run > type, "cmd" > type, "ping 192.168.1.1 -t". Press CTRL+C to stop.

What are you using to connect wirelessly, Windows Zero Configuration (WZC) service?

If that's the case, there is an issue where WZC will "roam" at 1 minute intervals causing periodic lag. You'll have to disable WZC (no work around to disable roaming only) and use a third party software (most wireless cards will come with one).

i have windows XP, a built-in Atheros 108mbps wifi card (im using a laptop), belkin 54g router, 4mb ntl/virgin connection. tried what you said, got two spikes, one 32mb packet took 32ms, one took 11ms, all others took 1ms, test of 50. wifi connection is connected using atheros client utility....
