/**
|
||||
* THIS IS A SHIM. IT SHOULD NOT BE INCLUDED IN FUTURE CODE. DEPRECATED, DO NOT USE.
|
||||
*
|
||||
* This is used to replace the machine var in mob, it is a holdover of pre-tgui code.
|
||||
* This component operates similar to how the machine var did previous, but better contained.
|
||||
* Any uses of set_machine() should eventually be removed in favor of tgui handling instead.
|
||||
*
|
||||
* All this does is ensure that the mob releases the machine when they leave it.
