how to make recognizable a cvar inside g_main.c from bg_pmov

[3xistence]

Hi
There's any way in order to use a game cvars in order to alter the bg_pmove.c stuff?
Let me be more clear:
I got a cvar inside g_main.c and g_local.c, this cvar needs to alter, if active, some code inside bg_pmove.c where the code was replaced by a if ( g_fwp.integer == 1 ) {
} else {

obviously bg_pmove doesn't recognize the cvar, any way to extern the cvar in order to be recognized also in bg_pmove?
The cvar will need to be modified by Callvote func

checking and trying to find a way from here

A couple of ways that I've used before:

1. copy the method they used for pmove_msec: add identically named cvars to game and cgame, add an int or float to pmove_t and set it to the cvar value through ClientThink_real().

2. First create a bg_cvars.h file, include it in bg_pmove.c, g_local.h and cg_local.h. Add identically named cvars to game and cgame and add an extern declaration for it in bg_cvars.h.

There's another possible way (untested) that may actually be the proper way of doing it. Make that bg_cvars.h listed in point 2. Create a bg_main.c file, add it to your makefile near the top of the listing, include q_shared.h in bg_main.c, copy over the cvarTable_t struct from g_main.c, make a table like gameCvarTable and create new cvars there just like you'd do in game or cgame but using bg_cvars.h (as opposed to g_local.h or cg_local.h) for your declaration.

thanks muffin. I added you, i think, also on QL. i think i will use the second option. Did you managed the ramp jump stuff?

Yep got it exactly the same as in Q2... spotted it while I was porting over Q2 physics. It was incredibly easy to add. In PM_CheckJump you change this:

Code: Select all

pm->ps->velocity[2] = JUMP_VELOCITY;

...to this...

Code: Select all

pm->ps->velocity[2] += JUMP_VELOCITY;

That's all it is... additive jump velocity. Then you can just cap the velocity so it doesn't get out of hand. Q2 caps the it to about 1.6 * JUMP_VELOCITY, I did 1.75 instead.

sorry for the question but add the cvar also on cgame is necessary also if this cvar will be used only by server and can be called only with callvote? i need also to understand how to force a map_restart when the cvar get modified after the callvote g _aircontrol 1 etc...

[themuffinman]

Because 'bg' stands for 'both games', in other words cgame + game and sometimes ui. So you have to include it in both.

For the callvote thing you can check out Cmd_CallVote_f in g_cmds.c. Add your cvar as an extra option and do some copy + pasting of the map_restart section.

the second way was the best one, i assigned the CVARs only on game like CVARS_SERVERINFO,
now i need only to add a map_restart everytime the cvar changes and create the stuff for ruleset.

I'm actually working a lot on hud and graphic (ever with this weird monospaced stuff because i'm still unable to turn on the TA fonts) and game behaviour. The UI sucks a lot but for now everything looks to works well.

There's a way in order to log stuff when the game crashes? (it happends only on one new gametype)
