Exploding Machine Gun
Bullets - By Ad0
In this tutorial I will
explain to you how command line arguments work in the Quake 3:
Arena console. The meaning of this is that you can choose more
functions from ONE single command using parameters. And that
can save some time, thinking of bindings to the keyboard and
so on.
Well!
Let's start with some easy coding for making this tutorial E A
S Y :)
--
Open
g_cmds.c and scroll down around line 57, AFTER the function
DeathmatchScoreboardMessage.
Ok, I guess you're there now,
so I guess you're ready to do some coding!
Ok, the
first thing to do is to create a
"comment mark" to easily find back to your code, so just snag
a comment area and paste it around line 57 UNDER
DeathmatchScoreboardMessage function. Call the function
whateveryou want, but don't use space between words!:
/*
=================
Cmd_MyFunc_f
=================
*/
void Cmd_MyFunc_f( gentity_t *ent )
{
char *msg; // message to player
char
arg1[MAX_STRING_TOKENS]; //argument string
var.
trap_Argv( 1, arg1, sizeof( arg1 ) ); //catch
the parameter
text
if (
!Q_stricmp( arg1, "arg1" ) ) { //check for parameter
"arg1"
msg
= "Argument 1 typed in!\n";
} else if (
!Q_stricmp( arg1, "arg2" ) )
{
msg
= "Argument 2 typed
in!\n";
} else
{
msg = "no
parameters or wrong parameter!!!\n"; //if none of
above
}
trap_SendServerCommand(
ent-g_entities, va("print \"%s\"", msg));
//prints the
message var --> msg to the local console!
} //The very
end of Cmd_MyFunc_f
After you've done
this paste/writeoff, you must make this function aviable in
the console, by adding it to the commands code at the end of
g_cmds.c.
I recommend you to write off instead of paste.
maybe try to add a third argument, and figure more things out!
It's healthy for your brain!
Ok, enough talking,
lets get back to coding!
Scroll down to the very end, and
after that, crawl your way up the source until you
hit:
else if (Q_stricmp (cmd, "god") ==
0)
Cmd_God_f
(ent);
Copy this, paste it
right under and modify to:
if (Qstricmp (cmd, "MyFunc" ==0) //command name
in console
Cmd_MyFunc_f
(ent); //the function name must be like the
function!
And there you go!
Command Line arguments!
Compile and launch
Quake 3 (you must know how to compile and stuff before getting
into any Quake 3 C coding)
When you're entering q3arena
and writing "/MyFunc arg1", the console responds: "Argument 1
typed in!". figure the rest out of
yourself...
Try to develop this,
and learn from it.
This is my first Quake 3: Arena coding
tutor, so don't get angry by errors... just mail the bugs to
me. The mail address is locatedon the top.
Cheers!
