Naming conventions
------------------
* e.g. `foomod_foothing.png`
* e.g. `foomod_foothing`
+
+Normalmap Textures
+------------------
+
+If shaders and bumpmapping or parallax occlusion is enabled, Minetest tries
+to load normalmaps.
+Those image files have to end with `_normal.png` and start with the same name
+as their corresponding texture.
+For example a normalmap for `foomod_foothing.png` has to be called
+`foomod_foothing_normal.png`.
+
+The sRGB R, G and B colour values of a normalmap pixel are each directly
+mapped from `{0, ..., 255}` to `[-1, 1]` and, taken together,
+define the normal vector.
+The alpha channel defines the heightmap for parallax occlusion.
+To be safe, the alpha values should always be bigger than zero
+because the colour values, which define the normal vector,
+may be undefined for image formats where colour is discarded in fully
+transparent pixels.
+
+Bumpmapping and parallax occlusion are currently experimental features:
+
+* Bumpmapping in Minetest happens in an obscure way; there are no light sources
+ defined in the shaders except the sunlight direction.
+* Parallax occlusion with relief-mapping mode does not yet work correctly
+ together with Minetest's Fastfaces.
+* The normalmap files must end with `.png`, so other image files are not
+ supported.

Texture modifiers
-----------------
There are a bunch of different looking node types.
-Look for examples in `games/minimal` or `games/minetest_game`.
+Look for examples in `games/devtest` or `games/minetest_game`.
* `normal`
* A node-sized cube.
text. Specify `0xFFFFFF` for white text, `0xFF0000` for red, and so on.
* `alignment`: The alignment of the text.
* `offset`: offset in pixels from position.
+* `size`: size of the text.
+ The player-set font size is multiplied by size.x (y value isn't used).
### `statbar`
* `world_pos`: World position of the waypoint.
* `offset`: offset in pixels from position.
+### `compass`
+
+Displays an image oriented or translated according to current heading direction.
+
+* `size`: The size of this element. Negative values represent percentage
+ of the screen; e.g. `x=-100` means 100% (width).
+* `scale`: Scale of the translated image (used only for dir = 2 or dir = 3).
+* `text`: The name of the texture to use.
+* `alignment`: The alignment of the image.
+* `offset`: Offset in pixels from position.
+* `dir`: How the image is rotated/translated:
+ * 0 - Rotate as heading direction
+ * 1 - Rotate in reverse direction
+ * 2 - Translate as landscape direction
+ * 3 - Translate in reverse direction
+If translation is chosen, texture is repeated horizontally to fill the whole element.
Representations of simple things
================================
* `2`: the node always gets the digging time 0.5 seconds (rail, sign)
* `3`: the node always gets the digging time 0 seconds (torch)
* `disable_jump`: Player (and possibly other things) cannot jump from node
+ or if their feet are in the node. Note: not supported for `new_move = false`
* `fall_damage_add_percent`: damage speed = `speed * (1 + value/100)`
* `falling_node`: if there is no walkable block under the node it will fall
* `float`: the node will not fall through liquids
* Simple colored box
* `color` is color specified as a `ColorString`.
If the alpha component is left blank, the box will be semitransparent.
+ If the color is not specified, the box will use the options specified by
+ its style. If the color is specified, all styling options will be ignored.

* See [Styling Formspecs].
+### `set_focus[<name>;<force>]`
+
+* Sets the focus to the element with the same `name` parameter.
+* **Note**: This element must be placed before the element it focuses.
+* `force` (optional, default `false`): By default, focus is not applied for
+ re-sent formspecs with the same name so that player-set focus is kept.
+ `true` sets the focus to the specified element for every sent formspec.
+* The following elements have the ability to be focused:

+
+Detached & nodemeta inventories provide the following callbacks for move actions:
+
+#### Before
+
+The `allow_*` callbacks return how many items can be moved.
+
+* `allow_move`/`allow_metadata_inventory_move`: Moving items in the inventory
+* `allow_take`/`allow_metadata_inventory_take`: Taking items from the inventory
+* `allow_put`/`allow_metadata_inventory_put`: Putting items to the inventory
+
+#### After
+
+The `on_*` callbacks are called after the items have been placed in the inventories.
+
+* `on_move`/`on_metadata_inventory_move`: Moving items in the inventory
+* `on_take`/`on_metadata_inventory_take`: Taking items from the inventory
+* `on_put`/`on_metadata_inventory_put`: Putting items to the inventory
+
+#### Swapping
+
+When a player tries to put an item to a place where another item is, the items are *swapped*.
+This means that all callbacks will be called twice (once for each action).
+
`ItemStack`
-----------
* `set_yaw(radians)`: sets the yaw (heading).
* `get_yaw()`: returns number in radians
* `set_texture_mod(mod)`
+ * Set a texture modifier to the base texture, for sprites and meshes.
+ * When calling `set_texture_mod` again, the previous one is discarded.
+ * `mod` the texture modifier. See [Texture modifiers].
* `get_texture_mod()` returns current texture modifier
-* `set_sprite(p, num_frames, framelength, select_horiz_by_yawpitch)`
- * Select sprite from spritesheet with optional animation and Dungeon Master
- style texture selection based on yaw relative to camera
- * `p`: {x=number, y=number}, the coordinate of the first frame
- (x: column, y: row), default: `{x=0, y=0}`
- * `num_frames`: number, default: `1`
- * `framelength`: number, default: `0.2`
- * `select_horiz_by_yawpitch`: boolean, this was once used for the Dungeon
- Master mob, default: `false`
+* `set_sprite(p, num_frames, framelength, select_x_by_camera)`
+ * Specifies and starts a sprite animation
+ * Animations iterate along the frame `y` position.
+ * `p`: {x=column number, y=row number}, the coordinate of the first frame
+ default: `{x=0, y=0}`
+ * `num_frames`: Total frames in the texture, default: `1`
+ * `framelength`: Time per animated frame in seconds, default: `0.2`
+ * `select_x_by_camera`: Only for visual = `sprite`. Changes the frame `x`
+ position according to the view direction. default: `false`.
+ * First column: subject facing the camera
+ * Second column: subject looking to the left
+ * Third column: subject backing the camera
+ * Fourth column: subject looking to the right
+ * Fifth column: subject viewed from above
+ * Sixth column: subject viewed from below
* `get_entity_name()` (**Deprecated**: Will be removed in a future version)
* `get_luaentity()`
* Only affects formspecs shown after this is called.
* `get_formspec_prepend(formspec)`: returns a formspec string.
* `get_player_control()`: returns table with player pressed keys
- * The table consists of fields with boolean value representing the pressed
- keys, the fields are jump, right, left, LMB, RMB, sneak, aux1, down, up.
- * example: `{jump=false, right=true, left=false, LMB=false, RMB=false,
- sneak=true, aux1=false, down=false, up=false}`
+ * The table consists of fields with the following boolean values
+ representing the pressed keys: `up`, `down`, `left`, `right`, `jump`,
+ `aux1`, `sneak`, `dig`, `place`, `LMB`, `RMB`, and `zoom`.
+ * The fields `LMB` and `RMB` are equal to `dig` and `place` respectively,
+ and exist only to preserve backwards compatibility.
* `get_player_control_bits()`: returns integer with bit packed player pressed
- keys.
- * bit nr/meaning: 0/up, 1/down, 2/left, 3/right, 4/jump, 5/aux1, 6/sneak,
- 7/LMB, 8/RMB
+ keys. Bits:
+ * 0 - up
+ * 1 - down
+ * 2 - left
+ * 3 - right
+ * 4 - jump
+ * 5 - aux1
+ * 6 - sneak
+ * 7 - dig
+ * 8 - place
+ * 9 - zoom
* `set_physics_override(override_table)`
* `override_table` is a table with the following fields:
* `speed`: multiplier to default walking speed value (default: `1`)
