Well,
if you can use the modul system, you could write a small trigger like this in module_triggers:
(0.1, 0, ti_once, [(map_free,0)],
[
(troop_add_item,"trp_player", item_id, modifier),
(troop_add_item,"trp_player", item_id, modifier),
(troop_add_item,"trp_player", item_id, modifier),
(troop_add_item,"trp_player", item_id, modifier),
]),
item_id has to be the name of the item and modifier is optional and can be 0 i think, haven't tried it.
Cause of the ti_once the trigger runs only one time, so take one of you savegames, load it, make the screenshots and don't save, then repeat. To add more items at once, just copy paste one of the (...), parts.
If you use the txt's just say so and i will try to compile the code and send it per pm.
Great work, love it!
