ORIGINAL PR: tgstation/tgstation@659a343
@Fikou requested this and it seemed like a good idea. This change the pattern for "how we declare that we don't want a station trait to actually exist" from "it's a bitfield" to the other commonly-used pattern of "it's a var which points at a typepath". The purpose of doing this is that most of the station traits which have an abstract parent want the default
trait_flags
value of their grandparent and have to redeclare it for no reason, which becomes more tedious the more children there are. This means that you don't need to do that because theabstract_type
var will only evaluate to true when checked on the specified abstract type, without needing to change its value on any children.Makes extending traits marginally easier
