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
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.
* 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
* Implement minetest.register_on_userlimit_check
This new callback permits to bypass the max_users parameter with new mods condition, based on player name or IP
Only one mod needs to permit it.
Move core part for builtin privileges checks to builtin
* Formspec: Add options to set background color and opacity (fullscreen mode)
* Enhance previous comment: Set formspec background when regenerate UI.
* This permit to do the calcul only at regen and override it with bgcolor tag
* Add a setting for default background color into formspec, separated from fullscreen
* Add a little performance gain on formspecs using a const ref instead of copying formspec string
Move client 'controls', 'graphics' and 'sound' into the first level to be
immediately visible to players who may not realise these come under 'client'.
These are the settings that new players or players on a server are likely to
want to access while not having understanding of what comes under 'client'.
Leave client 'network' and 'advanced' under 'client' as these are more
advanced.
Move 'show entity selection boxes' from the bizarre location in
'client'>'network' to 'graphics'>'in game'>'advanced'.
* Setting: Safe digging and placing
* New setting 'safe_dig_and_place' under Controls
* If set, digging and placing will not auto-repeat
* Releasing buttons unblocks the respective action again
* Useful for inexperienced users in creative mode where default
repeat times may be too short
* Safe placing (right click repetition) does not need a guarding flag
* Added new setting to minetest.conf.example
* Respect object property hp_max field for players
This allows modders to configure the maximal HP per player
* Statbars: Downscale bar to full 20 HP when exceeding this value
Add default max HP for players and breath constants to builtin
Document the constants
* Rename PLAYER_MAX_HP -> PLAYER_MAX_HP_DEFAULT
* Make world creation menu automatically generate a name.
* Name is now initialy empty, and generated if player tries to create a world without a name.
Minetest performance improvement has been huge since months, server step reduction will permit to handle client events a little bit faster without too many penalty costs due to core engine
Allows setting of the mountain 'zero level' (y where density gradient is zero).
It is easy to vertically shift smooth terrain by editing noise parameter 'offset',
but vertically shifting mountain terrain was complex and imprecise, involving
making a calculation based on an average of the mountain height parameter.
The change from 800x600 to 1024x576 (16:9) was a reduction in height which caused
user interface to become smaller.
Continue to use width 1024 as it is a common small screen width.
