Makes the liquid waving shader per-nodedef like waving leaves/plants,
instead of being applied to all liquids.
Like the waving leaves/plants shaders, the liquid waving shader can
also be applied to meshes and nodeboxes.
Derived from a PR by t0ny2.
Like randomwalk caves, preserve nodes that have 'is_ground_content = false',
to avoid dungeons that generate out beyond the edge of a mapchunk destroying
nodes added by mods in 'register_on_generated()'.
Issue discovered by, and original PR by, argyle77.
* Add sounds for falling and attached nodes
The sound specified in `node_definition.sounds.fall` is used.
When a falling node is spawned at a position or an attached node drops, the sound is played at this position.
* allow all sorts of soundspecs
- minetest.get_hit_params
- minetest.get_dig_params
- table.indexof
- Scope of minetest.register_alias
- Vector function parameters
- More explanation of when `minetest.on_player_receive_fields` is called
- Syntax/semantics of the fields in `minetest.on_player_receive_fields`
Store the rotation in the node as a 4x4 transformation matrix internally (through IDummyTransformationSceneNode), which allows more manipulations without losing precision or having gimbal lock issues.
Network rotation is still transmitted as Eulers, though, not as matrix. But it will stay this way in 5.0.
* Add missing tables of registered things
* Eliminate some duplication
Registration functions in 'Registered definitions' section merged into
'Registration functions' section.
* Misc. fixes
* Add privilege definition table
* Remove not-special soil group from special groups
* Merge two registration functions sections
* Move 'added to' information to tables section
Also fix some capitalization and missing periods
* Minor fixes
* Split Registration functions into two subsections
And update Registered definition tables to match order
* Fixes
* Adds Lua methods 'set_rotation()' and 'get_rotation'. Also changed some method names to be more clear. Instead of an f32 being sent over network for yaw, now a v3f is sent for rotation on xyz axes. Perserved Lua method set_yaw/setyaw so that old mods still work, other wise to set yaw they would need to switch to set_rotation(0, yaw, 0).
Mods will now have to initialize the list/slot in order to define the default player hand.
They may use the inventory callbacks to prevent abuse of this list.
