Why can't I add a new variable to forcedata_t?

[Vruki Salet]

I tried to add a new int variable to the forcedata struct and it makes the game quit at spawn time with a complaint about BG_EvaluateTrajectory. Any ideas about this? Where is the number of members of this struct set?

because it is used in the playerState_t struct which you cannot modify it especially the size of it. its best to not modif anything in q_shared.c / h

The playerState_t struct is exactly what I wanted to add some things to. Am I out of luck there?

[Tinny]

Yeah, unless your doing some compiler stuff you can't really add things to q_shared.c or q_shared.h. This is why, you know when you edit b_pmove.c it changes for both the server and client projects? q_shared.h is a file not just for those two but also unreleased code for the rendering and network code and other engine stuff. So if server and client runs one version of q_shared.h and the renderer and network code runs another it really messes stuff up.

Well, there are a couple of options....

 

1. you can use some of the unused/rarely used data slots in the playerstate. namely, some of the slots in the stats array aren't used that can be used.

 

2. use ext_data/mp/*_overrides.txt files to change the size of the entitystate/ playerstate to include the user floats/ints. Please note that is will make your mod incompatible with basejka servers and such, since it changes the size of the game packets.

Quoth Tinny:

 

"...but also unreleased code f..."

 

Ah there's my answer. I forgot about that aspect of things.

 

& Quoth Razorace:

 

"...use some of the unused/rarely used data slots..."

 

Yeah that's what I'll do if I really think it's worth it but I'll probly hold off since there're are only so many slots.

 

Thanks for the overerides tip. I never thought of using those and they could come in handy someday.

Yeah, I know. I was partially responsible for asking Raven to do that for us.
