* Force send a mapblock to a player.
Send a single mapblock to a specific remote player.
This is badly needed for mods and games where players are teleported
into terrain which may be not generated, loaded, or modified
significantly since the last player visit.
In all these cases, the player currently ends up in void, air, or
inside blocks which not only looks bad, but has the effect that the
player might end up falling and then the server needs to correct for
the player position again later, which is a hack.
The best solution is to send at least the single mapblock that the
player will be teleported to. I've tested this with ITB which does this
all the time, and I can see it functioning as expected (it even shows
a half loaded entry hallway, as the further blocks aren't loaded yet).
The parameter is a blockpos (table of x, y, z), not a regular pos.
The function may return false if the call failed. This is most likely
due to the target position not being generated or emerged yet, or
another internal failure, such as the player not being initialized.
* Always send mapblock on teleport or respawn.
This avoids the need for mods to send a mapblock on teleport or
respawn, since any call to `player:set_pos()` will pass this code.
* 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).
Also, use a better distance calculation for 'collide with objects'.
Fixes the issue of a vehicle occasionally colliding with its own driver,
causing one of the velocity components to be set to zero.
In the client, raise lower limit from 30 to 45 degrees, to avoid server
seeing this as a zoom and loading world beyond the server-set limit.
Add minimum in settingtypes.txt and enforce lower limit when set using
minetest.conf.
In the server, distrust the client-sent FOV if below the heuristic zoom
threshold and use the player object property 'zoom_fov' to check it, to
protect against hacked clients.
Remove player object property 'can zoom'.
Add player object property 'zoom fov'.
Remove clientside setting for 'zoom fov'.
Object property default is 15 degrees in creative mode, zoom disabled
in survival mode.
Needed due to zoom now loading and/or generating distant world
according to zoom FOV.
Update object properties serialisation version to 3.
* Make Player::peer_id server-side only and add getters and setters
Player::peer_id has no sense client side, move it to server, make it private and add setter and getter
Also add some PEER_ID_INEXISTENT instead of harcoded 0
* 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
* Fix animation frame_speed and blend loosing precision due to incorrect data type
Add lua function set_animation_frame_speed to update the frame speed without resetting the animation to start
* 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
This commit introduces Raycast, a Lua user object, which can be
used to perform a raycast on the map. The ray is continuable, so one can
also get hidden nodes (for example to see trough glass).
* C++11 patchset 9: move hardcoded init parameters to class definitions
C++11 introduced the possibility to define the default values directly in class definitions, do it on current code
Also remove some unused attributes
* CollisionInfo::bouncy
* collisionMoveResult::collides_xy
* collisionMoveResult::standing_on_unloaded
* Clouds::speed
* More constructor cleanups + some variables removal
* remove only write guiFormSpecMenu::m_old_tooltip
* move header included inside defintions in genericobject.h
* remove some unused since years exception classes
* remove unused & empty debug_stacks_init
* remove unused & empty content_nodemeta_serialize_legacy
* remove forgotten useless bool (bouncy) in collision.cpp code
* LuaEntitySAO: Remove beyond outermost mapchunk edges
Based on a commit by, and with help from, nerzhul.
Add 2 functions to class Mapgen:
A function to calculate actual mapgen edges, called from the Mapgen constructor.
A function called indirectly from content_sao.cpp per entity step to check SAO
position is within mapgen edges.
* Calculate borders from params not mapgen, which is not available everytime
