source: code/branches/tutorial/data/gui/scripts/PickupInventory.lua @ 8577

Last change on this file since 8577 was 7504, checked in by dafrick, 14 years ago

Pickups module is now (from what I can tell after some basic testing) fully functional over the network.
However it's still a little messy, needs some cleanup and documentation.
I introduced a new class, the PickupListener, which allows reacting to pickups becoming used, unused, picked up or dropped.
