* Add session_t typedef + remove unused functions
u16 peer_id is used everywhere, to be more consistent and permit some evolutions on this type in the future (i'm working on a PoC), uniformize u16 peer_id to SessionId peer_id
* Update JsonCPP to 1.8.3
* Fix deprecated functions
Json::FastWriter, Json::StyledWriter and Json::Reader are marked deprecated since 1.1 and are deprecated in 0.8 but not shown at compilation time.
Use new methods to serialize/deserialize
Implement network communication for channels
* Implement ModChannel manager server side to route incoming messages from clients to other clients
* Add signal handler switch on client & ModChannelMgr on client to handle channels
* Add Lua API bindings + client packet sending + unittests
* Implement server message sending
* Add callback from received message handler to Lua API using registration method
Change OpenAL distance model from AL_INVERSE_DISTANCE to
AL_INVERSE_DISTANCE_CLAMPED to avoid excessive volume when very close
to the sound location, for example MTG doors, and MTG fire sounds which
are combined at an average position and often located in air nodes.
Because AL_REFERENCE_DISTANCE has been reduced to 1 node (the distance
under which gain is clamped), multiply volume by the same factor to keep
sound gains the same as before, since the gain is calculated as:
gain = (AL_REFERENCE_DISTANCE / distance)
Feature is unnecessary and would greatly complicate future development,
it would also make 'get biome at pos' extremely complex.
Mgv7: Revert option to repeat surface biomes in floatlands, which
depended on the above.
Error was exposed by commit a1389c38658fe69c3bd25c3099bae9a4e51ed401
'nplaced' was not set to U16_MAX when biome 'stone' was placed, so when
biome was recalculated in a column of stone, the 'nplaced' value
caused a few remaining filler nodes to be placed.
Occurs when the lower biome has a deeper depth of 'top' plus 'filler'
than the upper biome.
For 3D noise tunnels only, replace unsupported biome 'top' and 'filler'
nodes in tunnel roof with the defined biome 'stone'.
This makes terrain created by 3D noise tunnels consistent with the rest
of mapgen, which does exactly the same in this situation.
The 'glow' value is added to the ambient light value.
Negative 'glow' disables light's effect on object colour, for faking
self-lighting, UI-style entities, or programmatic colouring in mods.
Dig prediction allows clients to remove dug nodes without
waiting for server acknowledgement.
This patch allows mods to override dig prediction,
it can either be turned off or a different "prediction node"
can be selected.
* Abort set_item when it does nothing
* Do not adjust dropped item size linearly
Instead use cube root because the item count is proportional to the volume, not to the length.
* Make the item rotate slower when it's bigger
Bigger items chafe more on the ground, so they can't rotate as fast as small ones
* Fix items flying in air
For precise control of schematic vertical position relative to the
'place_on' node.
Avoids workarounds that add empty nodes to a schematic and therefore
reduce performance.
Also remove long-unused decoration cutoff code.
