weapon properties not found in items.txt?

[tab]

i've been noticing this for stuff i've wanted to make: certain weapons seem to have properties that aren't referenced in items.txt at all.

for example, the sentry weapons (freedom bear, tennis ball launcher and it's combos) the claymore mine/detonator..

i was wondering if anyone had found where the details on the specific properties for these weapons are found.

the only thing i know is that it's dependent on name, and if you change the name of the item it does not function at all.

what kind of properties?

in general it's just entirely how they work, something that makes the specific weapons do stuff like act like sentryguns (tennisball launcher, freedom bear), or only detonate when an item is used (claymores + detonator that spawns on claymore use)
