Topic: [Mod] Animated torches [20120621][animatedtorches]
This simple mod uses a bit of code cobbled together from the default torches and from the recently-introduced animated lava to create proper, animated torches. All existing torches (wall, ceiling, floor) will be displayed with the new animated texture, but no nodes are being replaced. Inventory/wield image uses a frame from the on-floor texture. All textures by me (derived from a rendered torch and an actual burning flame).
As of 2012-09-02, this mod is part of the 'default' mod in minetest_game.
For those using older builds, this mod requires a build or git pull of Minetest dated June 17, 2012 or later, and the stuff below applies as before.
Dependencies: just the default stuff.
License: GPL for the code, WTFPL for the textures.

Install: Unzip the file, rename the resultant VanessaE-animatedtorches-blahblah folder to just "animatedtorches", and move it into Minetest's mods folder.
