Q3 documentation project

[Commodus]

Over at Quake 3 World there is a code documentation project which is striving to document all the trap_ functions in Quake 3 which can more or less be applied to JK2. Check it out if you haven't already done so.

 

Also, does anybody know what exactly does the void va(...) function do? (first argument is a string, all the arguments after are variables of any type)

 

Thanks,

Commodus

Nobody knows?

oh, sorry, didn't see that question

 

 

do you know the printf functions from the basic libraries?

 

It is an sprintf to an static function var. It returns a pointer to that var.

 

It is used for all the G_Printf like functions too.

 

It can only be used twice in capsulated functions.

 

 

G_Printf("%s",va("%i: %s",i,va("%f: %s",1.0,"HUHU")));

 

would not have the effect which is wanted ( beside it is silly and useless ). But there could be cases on which the limit of 2 is broken ( only a second call until one call is finished ).

Thanks for the link. I know at least some of it doesn't apply to JK2, but the rest is still good.

Ahh, so say

 

weapon = "bleh";

va("models/weapons2/%s/%s.glm", weapon");

 

Would give you a string with "models/weapons2/bleh/bleh.glm" in it? Sorry if I misunderstood you, I'm not much of a coder, but I'm trying to learn.

[Jaii der Herr]

char weapon[256] = "bleh";

 

va("models/weapons2/%s/%s.glm", weapon,weapon);

 

that would give you "models/weapons2/bleh/bleh.glm" as result

for every % you need a var in the parameter list.

just have a look at some help about printf functions

Ok. Thanks for the help =)
