<function name="setfenv" parent="debug" type="libraryfunc"> <description> <deprecated></deprecated> Sets the environment of the passed object. Unlike <page>Global.setfenv</page>, this also works on **any** userdata, allowing you to save data stored to it which can be accessed using <page>debug.getfenv</page>. Userdata seem to intentionally support this & setting/changing it does not affect anything (though unused by gmod / Entities and such don't this) This can be useful when trying to store data on a <page>IGModAudioChannel</page>, <page>Vector</page>, <page>Angle</page> or any other that doesn't already allow you to store data on it. </description> <realm>Shared and Menu</realm> <args> <arg name="object" type="any">Object to set environment of.
