+# 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.
+
+Created by [Rui](https://github.com/Rui-Minetest), this document was written by [sloantothebone](https://github.com/sloantothebone).
+
+## 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)
+
+As there is no automatic way to determine which version is used, this must be configured with advanced settings menu, or by manually editing `playeranim.model_version` entry in minetest.conf.  
+The default value is `MTG_4_Jun_2017`.
+
+Symptoms of having configured the incorrect player model:
+- In rest, arms are raised up, and are either detached from the body, or are too close to the body
+- Cape (if visible) points upward
+
+### The delay of sideways body rotation
+
+Configure `playeranim.body_rotation_delay`.
+It's the number of frame delay of sideways body rotation.  
+The default value is `7`.
+
+### Lengthways body rotation in sneaking
+
+Configure `playeranim.body_x_rotation_sneak`.
+It's the degrees of the body's X-axis rotation in sneaking.  
+The default value is `6.0`.
+
+### The speed of an animation
+
+Configure `playeranim.animation_speed`.
+It's the number of stepping per seconds.  
+The default value is `2.4`.
+
+### The speed of an animation in sneaking
+
+Configure `playeranim.animation_speed_sneak`.
+It's the number of stepping per seconds in sneaking.  
+The default value is `0.8`.
