A little help for a mod

[mik1]

I started a map that uses the trigger_key to spawn ammo, i was thinking of making some kind of shop system mainly for testing. When i tried it, it activates once and stays that way, because in the main game theres no need for repeating key doors.
I want to know if its possible to modify the key function so instead of removing itself on activation, it would repeat so it can be used again, kinda like what buttons do.

I found a code that should be the trigger_key actions.

/*211 ==============================================================================
212
213 trigger_key
214
215 ==============================================================================
216 */
217
218 /*QUAKED trigger_key (.5 .5 .5) (-8 -8 -8) (8 8 8)
219 A relay trigger that only fires it's targets if player has the proper key.
220 Use "item" to specify the required key, for example "key_data_cd"
221 */
222 void trigger_key_use (edict_t *self, edict_t *other, edict_t *activator)
223 {
224 int index;
225
226 if (!self->item)
227 return;
228 if (!activator->client)
229 return;
230
231 index = ITEM_INDEX(self->item);
232 if (!activator->client->pers.inventory[index])
233 {
234 if (level.time < self->touch_debounce_time)
235 return;
236 self->touch_debounce_time = level.time + 5.0;
237 gi.centerprintf (activator, "You need the %s", self->item->pickup_name);
238 gi.sound (activator, CHAN_AUTO, gi.soundindex ("misc/keytry.wav"), 1, ATTN_NORM, 0);
239 return;
240 }

The Lazarus mod enables multi-use trigger_keys. You could just use Lazarus for your project.

Here's what it does at the end of that function:


// DWH: keep key
else if(!(self->spawnflags & 2))
{
activator->client->pers.inventory[index]--;
}

G_UseTargets (self, activator);

// DWH - multi-use
if(!(self->spawnflags & 1)) {
self->use       = NULL;
self->think     = G_FreeEdict;
self->nextthink = level.time + FRAMETIME;
gi.linkentity(self);
}

Also, please post code in a form that preserves the tabs for readability.
