[Postality]

Okay, I'm on a roll here. So let me keep going.

It took a while, but I did it.

Here's the item TYPES and thier funtionality

Example Code:
AddStaticPickup(346, 2, 1297.4008,-1848.4597,14.000); // gun
This is the TYPE-----^

If it's not listed it was not pickupable and no visable or audiable effect was apparent.

X = can't pick it up
* = will lock your movement forward if walked on (I don't advise using it.)

0 Item does not display
2 Pickupable and respawns after a few minutes
3 Pickupable, no respawn
4 Disappears shortly after creation (used for drops?)
5 Disappears shortly after creation (used for drops?)
8 pickupable (no effect) - disappears shortly after creation (used for ?)
11 Blows Up few seconds after creation*
12 Blows Up few seconds after creation (car explosion? timer is the burning flame?)
13 X - Slowly descends in Z and eventually goes through the floor (parachute?)
15 Pickupable, no respawn
19 Pickupable with no effect (Information icon?)
22 Pickupable, no respawn

I've tested all the way up to 50, but 23-50 is the same result so there's probably no more =)

Enjoy
