View Full Version : Client Server stuff in bg files:

06-17-2002, 01:40 AM
Okay, I've been using Quake III editing sites for most of my reference, and it appears that a few core things that QIII coders rely on are missing, and I was wondering if anyone had any ideas on how to get around them...

I'm trying to change the speed of a character based on what class he is. I want to multiply a scout's speed by 1.5, making him 50% faster... But first I need to know what class tha client is.

The place where you can alter his speed is located in a bg file, and is used so the client can predict his location without talking to the server. This means the only thing I have to work with is a playerstate_t, as it is the only thing shared between both the client and the server.

So my first thought was to add a new variable to the playerstate_t class, but that screws everything up, and my map appears with no entities at all on it.

Then I notice a comment above the playerstate struct, which says to change the contents of the playerstate I need to make changes to msg.c.

Unfortunately, there is no msg.c :-(

I also can't seem to get CVars to work in the bg file, so I'm pretty lost with what I can do next.

Any help would be most appreciated.

Don't change anything to q_shared.h or q_shared.c

(I agree with you now Ask :) )

if you change the playerstate struct the game will be screwed...
create an extern struct containing an array [MAX_ENTITY]
and add your changes to it ...
that's how i do it ...
(not very clean but it works )

can u explain with what you mean with "class" class of stance? class of model? class of weapons?

ever heard of team fortress?
he means character class like scout, sniper, engineer, medic, heavyweapons guy and stuff like that.

Team Fortress yes, but not in relation with JK2 :)

anyway, this has nothing todo with your above statement if i get it right, u want something like this:

switch( ent->client->pers.yourplayerclass )
case SCOUT:
client->ps.speed *= 1.2;
client->ps.speed *= 1.0;
case SITH:
client->ps.speed *= 1.1;

I need to do it in the bg file surely, otherwise if I do it in game, the client will predict the player's position incorrectly, as it will not be aware he's moving at 1.5x the normal speed.

Therefore I need to do it in BG_Move, which is called by both the client and the server, so I know they are both coming up with the same result.

As I said before, the only thing I have access to from here, (to my knowledge) is the playerstate_t.... I have the clientNum, but that's it, I don't even have access to the global entity or client lists.

you could also try placing it in g_active.c in the clientthink function, that won't give prediction errors.
