Q3: JK2: Source code help

evan1715 · **Posted:** 27 Oct 2007 01:40

ok if you are trying to add like a timer between things what would u use? for the JK2 source code on http://jediknight3.filefront.com/file/J ... Tools;2888 like say if u want to put a pause between a command and a message shows up that says "You can only change models every second" instead of a flood that can do it 1 milisecond, so basically i want it to be anti flood so they can only change models every 1 second, and it cant flood if its that slow, what kind of counter code would i put?

You can insert a time check like that used in rcon, the following is the code just from that check:

unsigned int time;
static unsigned int lasttime = 0;

time = Com_Milliseconds();
if ( (unsigned)( time - lasttime ) < 500u ) {
return;
}
lasttime = time;

substituite 500u with 1000u and naturally place the instruction in the right function which handles the models

yes, seems right.
unsigned is used in the quake3 code
Check if the function you are modifying is void otherwise you must return something (like NULL or zero and so on)

I think that the function you must check is ClientUserinfoChanged
For the moment try to add the piece of time code just at its beginning and check if works then you can continue with the optimizations.

you could subsituite it with another function.
For example time(NULL) returns the time in seconds which is also a good choice, remember only to substituite 1000u with 1

seems you have placed the instructions in the wrong place, try at line 1134

oh shit, time and time() that's the problem ih ih ih
rename time (the var, NOT time(NULL)) as timez and it will work.

If you continue to have problems with "unsingned" after this change substituite it with uint or uint32_t or just leave int alone.

unsigned int timez;
static unsigned int lasttime = 0;

timez = time(NULL);
if ( (unsigned)( timez - lasttime ) < 1 ) return;
lasttime = timez;

try to add #include <time.h> at the beginning of the file (not the function, just the entire file), if this doesn't work there is a function called FloatTime that you can use but you must use float values instead of unsigned int

float timez;
static float lasttime = 0;

timez = FloatTime();
if ( ( timez - lasttime ) < 1.0 ) return;
lasttime = timez;

you should check the source code of the mod searching for a function which gives you the time in milliseconds or seconds.
The Quake 3 engine uses FloatTime and Com_Milliseconds, for the other implementations of the engine (mods) I don't know.

search "protocol" (" included) in the source code and find when it's checked.
If you don't find it search PROTOCOL_VERSION and modify it as that of 1.02

I don't think Protocol is on the source, but rather the exe? Because I can't find it in the source.
Edit:
Yea I see it in the exe.

print.Server uses protocol version %i

In that case you need only to modify the executable which is an easy job.

For example take a look to the following assembly from the 1.02 executable for Windows where the needed protocol is 15 (0x0000000f in hex):

Code:

* Possible StringData Ref from Data Obj ->"protocol"
                                  |
:00426EC9 68D4334700              push 004733D4
:00426ECE 51                      push ecx
:00426ECF E81CC2FEFF              call 004130F0
:00426ED4 50                      push eax
:00426ED5 E8C13F0300              call 0045AE9B
:00426EDA 8BD8                    mov ebx, eax
:00426EDC 83C418                  add esp, 00000018
:00426EDF 83FB0F                  cmp ebx, 0000000F
:00426EE2 743A                    je 00426F1E
:00426EE4 6A0F                    push 0000000F

* Possible StringData Ref from Data Obj ->"print
Server uses protocol version "
                                        ->"%i.
"
                                  |
:00426EE6 68AC334700              push 004733AC
