View source for Since

Usually it's not simple to quickly and compactly define which games a feature is available in without listing everything, therefore this wiki is using few keywords like '''in''', '''since''', '''before''', '''all'''  to simplify this and sometimes it may not be entirely accurate. In case of using '''also in''' or '''only in''' it's straightforward what's meant when it comes to particular games but not so much when it comes to engine branches.

{{tip|If unsure what games an entity is available in check {{cmd|dump_entity_sizes}} page which lists all for each game. (entity being listed doesn't guarantee it's fully supported for the given game)}}
