ExperimentalGear/scripts/gameplay newest.lua

-- The following code slightly simplifies the render/update code, making it easier to explain in the comments
-- It replaces a few of the functions built into USC and changes behaviour slightly
-- Ideally, this should be in the common.lua file, but the rest of the skin does not support it
-- I'll be further refactoring and documenting the default skin and making it more easy to
--  modify for those who either don't know how to skin well or just want to change a few images
--  or behaviours of the default to better suit them.
-- Skinning should be easy and fun!
