+# playeranim
+
+Makes the head, and the right arm when you're mining, face the way you're facing, similar to Minecraft. Compatible with [3d_armor](https://github.com/stujones11/minetest-3d_armor). This is an ugly hack. Forked from [Kaeza's animplus mod](https://github.com/kaeza/minetest-animplus).
+
+The head only turns up and down relative to the body, except it turns slightly to the right/left when you strafe right/left. When you turn the body turns with the head.  
+Works in both singleplayer and multiplayer.

+## Configuration
+
+### Version of player model
+
+Player models supported by this mod:
+- `MTG_4_Jun_2017` (minetest_game after 4 Jun 2017, 0.4.16)
+- `MTG_4_Nov_2017` (minetest_game after 4 Nov 2017, 0.5.0)
