Registered definitions
======================
-Anything added using certain `minetest.register_*` functions gets added to
-the global `minetest.registered_*` tables.

+Anything added using certain [Registration functions] gets added to one or more
+of the global [Registered definition tables].
Note that in some cases you will stumble upon things that are not contained
in these tables (e.g. when a mod has been removed). Always check for
existence before trying to access the fields.
-Example: If you want to check the drawtype of a node, you could do:
+Example:
+
+All nodes register with `minetest.register_node` get added to the table
+`minetest.registered_nodes`.
+
+If you want to check the drawtype of a node, you could do:
local function get_nodedef_field(nodename, fieldname)
if not minetest.registered_nodes[nodename] then
type are ignored.
### `image`
+
Displays an image on the HUD.
* `scale`: The scale of the image, with 1 being the original texture size.
* `{type="object", ref=ObjectRef}`
Exact pointing location (currently only `Raycast` supports these fields):
+
* `pointed_thing.intersection_point`: The absolute world coordinates of the
point on the selection box which is pointed at. May be in the selection box
if the pointer is in the box too.
* `attached_node`: if the node under it is not a walkable block the node will be
dropped as an item. If the node is wallmounted the wallmounted direction is
checked.
-* `soil`: saplings will grow on nodes in this group
* `connect_to_raillike`: makes nodes of raillike drawtype with same group value
connect to each other
* `slippery`: Players and items will slide on the node.
* `disable_repair`: If set to 1 for a tool, it cannot be repaired using the
`"toolrepair"` crafting recipe
-
Known damage and digging time defining groups
---------------------------------------------
* `<fontcolor>` tooltip font color as `ColorString` (optional)
### `tooltip[<X>,<Y>;<W>,<H>;<tooltip_text>;<bgcolor>;<fontcolor>]`
+
* Adds tooltip for an area. Other tooltips will take priority when present.
* `<bgcolor>` tooltip background color as `ColorString` (optional)
* `<fontcolor>` tooltip font color as `ColorString` (optional)
### `item_image_button[<X>,<Y>;<W>,<H>;<item name>;<name>;<label>]`
-* `item name` is the registered name of an item/node,
- tooltip will be made out of its description
- to override it use tooltip element
+* `item name` is the registered name of an item/node
+* The item description will be used as the tooltip. This can be overridden with
+ a tooltip element.
### `button_exit[<X>,<Y>;<W>,<H>;<name>;<label>]`
Once the internal VoxelManip state has been modified to your liking, the
changes can be committed back to the map by calling `VoxelManip:write_to_map()`
