For those of you interested i am sending out Twilight and Vego muds
object trap stuff....it has been used a bit...but i won't guarantee
it is totally bug free....just make these changes and add in the trap.c
file. Hope i didn't forget anything ;)

Here is the object trap stuff.....
>>Add this to merc.h obj_data struct:
sh_int trap_eff;
sh_int trap_dam;
sh_int trap_charge;
>> Add this to merc.h areas of interest to builders
/* All new trap stuff */
#define TRAP_DAM_SLEEP -1
#define TRAP_DAM_TELEPORT 0
#define TRAP_DAM_FIRE 1
#define TRAP_DAM_COLD 2
#define TRAP_DAM_ACID 3
#define TRAP_DAM_ENERGY 4
#define TRAP_DAM_BLUNT 5
#define TRAP_DAM_PIERCE 6
#define TRAP_DAM_SLASH 7
#define TRAP_EFF_MOVE 1 /* trigger on movement */
#define TRAP_EFF_OBJECT 2 /* trigger on get or put */
#define TRAP_EFF_ROOM 4 /* affect all in room */
#define TRAP_EFF_NORTH 8 /* movement in this direction */
#define TRAP_EFF_EAST 16
#define TRAP_EFF_SOUTH 32
#define TRAP_EFF_WEST 64
#define TRAP_EFF_UP 128
#define TRAP_EFF_DOWN 256
#define TRAP_EFF_OPEN 512 /* trigger on open */
>> Add a new object extra flag in merc.h
#define ITEM_TRAP ####
>> Add these to do_functions in merc.h:
DECLARE_DO_FUN( do_trapset );
DECLARE_DO_FUN( do_trapremove );
DECLARE_DO_FUN( do_trapstat );
DECLARE_DO_FUN( do_traplist );
>> Add these to bottom of merc.h with other functions:
/* trap.c */
bool checkmovetrap args( ( CHAR_DATA *ch, int dir) );
bool checkgetput args( ( CHAR_DATA *ch, OBJ_DATA *obj) );
bool checkopen args( ( CHAR_DATA *ch, OBJ_DATA *obj) );
>> Add these to interp.c:
{ "traplist", do_traplist, POS_DEAD, L_DEI, LOG_NORMAL },
{ "trapstat", do_trapstat, POS_DEAD, L_DEI, LOG_NORMAL },
{ "trapset", do_trapset, POS_DEAD, L_DEI, LOG_NORMAL },
{ "trapremove", do_trapremove, POS_DEAD, L_DEI, LOG_NORMAL },
>> Add this to act_move.c in move_char:
>> after the bug for bad door block....
if ( checkmovetrap(ch, door) )
return;
>> Add this to act_move.c in do_open:
>> before REMOVE_BIT(obj->value[1], CONT_CLOSED);
if (checkopen(ch, obj) )
return;
>> Add this to act_obj.c in get_obj:
>> after "You can't take that!" block
if (checkgetput(ch, obj) )
return;
>> Add this to act_obj.c in do_put:
>> after the closed container check.
if (checkgetput( ch, container) )
return;
>> And of course...put in trap.c ;)
>> Below here is all the stuff required to load traps from .are files
>> Add to obj_index_data struct in merc.h:
sh_int trap_eff;
sh_int trap_dam;
sh_int trap_charge;
>> Add this to db.c in load_objects:
>> below pObjectIndex->extra_flags = fread_number( fp );
if (IS_SET(pObjIndex->extra_flags, ITEM_TRAP) )
{
pObjIndex->trap_eff = fread_number( fp );
pObjIndex->trap_dam = fread_number( fp );
pObjIndex->trap_charge = fread_number( fp );
}
else
{
pObjIndex->trap_dam = 0;
pObjIndex->trap_eff = 0;
pObjIndex->trap_charge = 0;
}
>> add this to db.c in create_object:
>> below the obj->cost assignment
obj->trap_eff = pObjIndex->trap_eff;
obj->trap_dam = pObjIndex->trap_dam;
obj->trap_charge = pObjIndex->trap_charge;
>> That should do it......
Just whenever you wanna load a trap..set the extra bit, then after the
extra bit place values for trap_eff, trap_dam, and trap_charge.
Works like a charm ;)
NOTE: Be very careful when using areas from other muds because if the ITEM_TRAP
extra bit is used in an area file....it will be looking for the trap numbers
after it.
