-- LUA Script - precede every function and global member with lowercase name of script + '_main'

-- sb_door script has been adapted from the default gg door script
-- modified by Reliquia

-- Script Purpose:
--	Player must have key if door is locked - specified by 'USE KEY' field
--	Allow player to Open\Close door when unlocked
--	Ensure door Collision point is altered depending on it being in open or closed positions

-- sr_door model resources:
--	Two animations stored in the model: 0=opening 1=closing
--	scriptbank\reliquia\sr_door: This script to facilitate animations

-- Audio
--	Opening: specified in sound0 field
--	Closing: specified in sound1 field
 

-- variables used by sb_door
sbdoor_pressed = 0 -- state to ensure user must release E key before can open/close again
