[quake 3] add a trap function ?

[Pierre Marti]

Hi,

Do you know how to add your own trap function ? 
I put my function in qcommon directory and I want to call it from the game directory (like for example the trap_FS_Write function). 
I do the same (definition/declaration) like the other trap functions but I suppose the problem is to find the correct id for the g_syscalls.asm. 

For example :


In qcommon/common.c : 

void example_trap_function( void ) 
{ 
int i = 12345; // only for for debug 
} 


In qcommon/q_shared.h: 

void example_trap_function( void ); 


In game/g_local.h: 

void example_trap_function( void ); 


In game/gpublic.h: 

in the gameImport_t enum adding the line : 

EXAMPLE_TRAP_FUNCTION 


In game/g_syscalls.c: 

void example_trap_function( void ) 
{ 
syscall( EXAMPLE_TRAP_FUNCTION ); 
} 

You have to modify the game.q3asm for compiling g_syscalls.c (replace line ../g_syscalls with g_syscalls) with ioquake3. 


In game/g_syscalls.asm: 

adding this line at the end of the file : 

equ trap_example_trap_function -584 

Is it my problem ? 
How to know the number ? 


In game/g_main.c: 

Use the example function in G_InitGame : 

trap_example_trap_function( ); 


Compiling is ok 
After installing everything (bin and qvm) and starting the game it's ok. 
When the map is launching (G_InitGame function) I have this message : 

bad game system trap -582 (same result if I choose -583)

582 is the number for the trap_BotLibSourceFileAndLine in the g_syscalls.asm file. 
I add my line after it...


Thank's
