-- LUA Script - precede every function and global member with lowercase name of script + '_main'
-- DESCRIPTION: smallg's animated pickup script 
-- DESCRIPTION: [SCRIPTNAME$="weapon"] (the script to call when player collects the item - don't put .lua)
-- DESCRIPTION: (include only/any subfolders after scriptbank - i.e. "objects\\key"
-- DESCRIPTION: [PROMPTTEXT$="Collect? (E)"] (the prompt to show when looking at item)
-- DESCRIPTION: [HOVERHEIGHT=30] (how far up the item will hover)
-- DESCRIPTION: [HOVERSPEED=60] (how quickly the item will rise and fall
-- DESCRIPTION: [SPINSPEED=15] (how quickly the item will spin (set a negative value to spin in the opposite direction))
-- DESCRIPTION: [PICKUPRANGE=120] (how far away item can be collected from)
-- DESCRIPTION: [PICKUPANGLE=10(1,180)] (angle the item can be picked up from)
-- DESCRIPTION: (set hoverspeed or spinspeed to 0 if you don't want to hover / spin)
