From 6e1372bd894d955300c40d69e5c882e9cc7d7523 Mon Sep 17 00:00:00 2001 From: Wuzzy Date: Mon, 11 May 2020 21:40:45 +0200 Subject: =?UTF-8?q?Add=20support=20for=20statbar=20=E2=80=9Coff=20state?= =?UTF-8?q?=E2=80=9D=20icons=20(#9462)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This adds support for optional “off state” icons for statbars. “off state icons” can be used to denote the lack of something, like missing hearts or bubbles. Add "off state" textures to the builtin statbars.
