Born from a silly idea over at Unreal Slackers,
this plugin implements a widget component for Unreal Engine that lets you
display Behavior Tree states as emoji above your AI pawns:
Just mark the BT nodes that you're interested in with the
EmojAI Display State service and add the EmojAI Display component to
your pawn:
For everything else, the component comes with a C++ and Blueprint API:
The plugin works with arbitrary strings of course, but where's the fun in that? Emoji characters turned out to be more useful than you'd initially think, they're very compact.
Don't forget that you can bring up the built-in emoji selector of Windows by
pressing Win+. or Win+; in the Unreal Editor!
