# mcl_mapgen
------------
Helps to avoid problems caused by 'chunk-in-shell' feature of mapgen.cpp.
It also queues your generators to run them in proper order:
### mcl_mapgen.register_on_generated(lvm_callback_function, order_number)
-------------------------------------------------------------------------
Replacement of engine API function `minetest.register_on_generated(function(vm_context))`
It is still unsafe. Cavegen part can and will overwrite outer 1-block layer of the chunk which is expected to be generated.
Nodes marked as `is_ground_content` could be overwritten. Air and water are usually 'ground content' too.
For Minetest 5.4 it doesn't recommended to place blocks within lvm callback function.
See https://git.minetest.land/MineClone2/MineClone2/issues/1395
* `lvm_callback_function`: chunk callback LVM function definition:
* `function(vm_context)`:
* `vm_context` will pass into next lvm callback function from the queue!
* `vm_context`: a table which already contains some LVM data as the fields, and some of them can be added in your lvm callback function:
* `vm`: curent voxel manipulator object itself;
* `chunkseed`: seed of this mapchunk;
* `minp` & `maxp`: minimum and maximum chunk position;
* `emin` & `emax`: minimum and maximum chunk position WITH SHELL AROUND IT;
* `area`: voxel area, can be helpful to access data;
* `data`: LVM buffer data array, data loads into it before the callbacks;
* `write`: set it to true in your lvm callback functionm, if you changed `data` and want to write it;
* `param2_data`: LVM buffer data array of `param2`, *NO ANY DATA LOADS INTO IT BEFORE THE CALLBACKS* - you load it yourself:
* `vm_context.param2_data = vm_context.param2_data or vm_context.vm:get_param2_data(vm_context.lvm_param2_buffer)`
* `write_param2`: set it to true in your lvm callback function, if you used `param2_data` and want to write it;
* `light`: LVM buffer data array of light, *NO ANY DATA LOADS INTO IT BEFORE THE CALLBACKS* - you load it yourself:
* `vm_context.light = vm_context.light or vm_context.vm.get_light_data(vm_context.lvm_light_buffer)`
* `write_light`: set it to true in your lvm callback function, if you used `light` and want to write it;
* `lvm_param2_buffer`: static `param2` buffer pointer, used to load `param2_data` array;
* `shadow`: set it to false to disable shadow propagation;
* `heightmap`: mapgen object contanting y coordinates of ground level,
* *NO ANY DATA LOADS INTO IT BEFORE THE CALLBACKS* - load it yourself:
* `vm_context.heightmap = vm_context.heightmap or minetest.get_mapgen_object('heightmap')`
* `biomemap`: mapgen object contanting biome IDs of nodes,
* *NO ANY DATA LOADS INTO IT BEFORE THE CALLBACKS* - load it yourself:
* `vm_context.biomemap = vm_context.biomemap or minetest.get_mapgen_object('biomemap')`
* `heatmap`: mapgen object contanting temperature values of nodes,
* *NO ANY DATA LOADS INTO IT BEFORE THE CALLBACKS* - load it yourself:
* `vm_context.heatmap = vm_context.heatmap or minetest.get_mapgen_object('heatmap')`
* `humiditymap`: mapgen object contanting humidity values of nodes,
* *NO ANY DATA LOADS INTO IT BEFORE THE CALLBACKS* - load it yourself:
* `vm_context.humiditymap = vm_context.humiditymap or minetest.get_mapgen_object('humiditymap')`
* `gennotify`: mapgen object contanting mapping table of structures, see Minetest Lua API for explanation,
* *NO ANY DATA LOADS INTO IT BEFORE THE CALLBACKS* - load it yourself:
* `vm_context.gennotify = vm_context.gennotify or minetest.get_mapgen_object('gennotify')`
* `order_number` (optional): the less, the earlier,
* e.g. `mcl_mapgen.order.BUILDINGS` or `mcl_mapgen.order.LARGE_BUILDINGS`
### mcl_mapgen.register_mapgen_block_lvm(lvm_callback_function, order_number)
-----------------------------------------------------------------------------
Registers lvm callback function to be called when current block (usually 16x16x16 nodes) generation is REALLY 100% finished.
`vm_context` passes into lvm callback function.
* `lvm_callback_function`: the block callback LVM function definition - same as for chunks - see definition example above;
* `order_number` (optional): the less, the earlier,
* e.g. `mcl_mapgen.order.BUILDINGS` or `mcl_mapgen.order.LARGE_BUILDINGS`
### mcl_mapgen.register_mapgen_block(node_callback_function, order_number)
--------------------------------------------------------------------------
Registers node_callback function to be called when current block (usually 16x16x16 nodes) generation is REALLY 100% finished.
* `node_callback_function`: node callback function definition:
* `function(minp, maxp, seed)`:
* `minp` & `maxp`: minimum and maximum block position;
* `seed`: seed of this mapblock;
* `order_number` (optional): the less, the earlier,
* e.g. `mcl_mapgen.order.BUILDINGS` or `mcl_mapgen.order.LARGE_BUILDINGS`
### mcl_mapgen.register_mapgen(callback_function, order_number)
---------------------------------------------------------------
Registers callback function to be called when current chunk generation is REALLY 100% finished.
For LVM it's the most frustrating function from this mod.
It can't provide you access to mapgen objects. They are probably gone long ago.
Don't use it for accessing mapgen objects please.
To use VM you have to run `vm_context.vm = mcl_mapgen.get_voxel_manip(vm_context.emin, vm_context.emax)`.
* `callback_function`: callback function definition:
* `function(minp, maxp, seed, vm_context)`:
* `minp` & `maxp`: minimum and maximum block position;
* `seed`: seed of this mapblock;
* `vm_context`: a table - see description above.
* `order_number` (optional): the less, the earlier.
### mcl_mapgen.register_mapgen_lvm(lvm_callback_function, order_number)
-----------------------------------------------------------------------
Registers lvm callback function to be called when current chunk generation is REALLY 100% finished.
It's the most frustrating function from this mod. It can't provide you access to mapgen objects. They are probably gone long ago.
Don't use it for accessing mapgen objects please.
`vm_context` passes into lvm callback function.
* `lvm_callback_function`: the block callback LVM function definition - same as above;
* `order_number` (optional): the less, the earlier.
### mcl_mapgen.get_far_node(pos)
--------------------------------
Returns node if it is generated, otherwise returns `{name = "ignore"}`.
### mcl_mapgen.clamp_to_chunk(x, size)
--------------------------------------
Returns new `x`, slighty tuned to make structure of size `size` be within single chunk side of 80 nodes.
### function mcl_mapgen.get_chunk_beginning(x)
----------------------------------------------
Returns chunk beginning of `x`. It is the same as `minp.axis` for per-chunk callbacks, but we don't always have `minp`.
## Constants:
* `mcl_mapgen.EDGE_MIN`, `mcl_mapgen.EDGE_MAX` - world edges, min & max.
* `mcl_mapgen.seed`, `mcl_mapgen.name` - mapgen seed & name.
* `mcl_mapgen.v6`, `mcl_mapgen.superflat`, `mcl_mapgen.singlenode` - is mapgen v6, superflat, singlenode.
* `mcl_mapgen.normal` is mapgen normal (not superflat or singlenode).

# mcl_time v2.2
## by kay27 for MineClone 5
---------------------------
This mod counts time when all players sleep or some area is inactive.
It depends very much on `time_speed` configuration variable, which could be changed 'on the fly' by a chat command:
* `/set time_speed 72`
If `time_speed` set to 0, this mod logs warnings and returns zeroes.
### mcl_time.get_seconds_irl()
------------------------------
Returns: Integer value of realtime (not in-game) seconds since world creation.
Usually this value grow smoothly. But when you skip the night being in the bed, or leave some area for some time, you may experience value jumps. That's basically the idea of this mod.
### mcl_time.get_number_of_times(last_time, interval, chance)
-------------------------------------------------------------
Returns the number of how many times something would probably happen if the area was active and we didn't skip the nights.
Arguments:
* `last_time` - you pass last known for you value of `seconds_irl`
* `interval` and `chance` - interval and chance like from ABM setup
Returns:
* Integer number of how many times something would probably happen if the area was active all the time and we didn't skip the nights.
* Integer value of in-real-life (not in-game) seconds since world creation.
### mcl_time.touch(pos)
-----------------------
This function 'toches' node at position `pos` by writing `_t` meta variable of `seconds_irl`.
### mcl_time.get_number_of_times_at_pos(pos, interval, chance)
--------------------------------------------------------------
Returns the number of how many times something would probably happen for node at pos `pos` if the area was active and we didn't skip the nights.
It reads and updates meta variable `_t` from position `pos` and uses it as previous `seconds_irl`, so we don't need to remember it.
Argunments:
* `pos` - node position
* `interval` and `chance` - interval and chance like from ABM setup
Returns:
* Integer number of how many times something would happen to the node at position `pos` if the area was active all the time and we didn't skip the nights.
* For unclear conditions, like missing meta or zero `time_speed`, this function will return `0`.
### mcl_time.get_number_of_times_at_pos_or_1(pos, interval, chance)
-------------------------------------------------------------------
Returns the number of how many times something would probably happen for node at pos `pos` if the area was active and we didn't skip the nights.
It reads and updates meta variable `_t` from position `pos` and uses it as previous `seconds_irl`, so we don't need to remember it.
Argunments:
* `pos` - node position
* `interval` and `chance` - interval and chance like from ABM setup
Returns:
* Integer number of how many times something would happen to the node at position `pos` if the area was active all the time and we didn't skip the nights.
* For unclear conditions, like missing meta or zero `time_speed`, this function will return `1`.
### mcl_time.get_number_of_times_at_pos_or_nil(pos, interval, chance)
---------------------------------------------------------------------
Returns the number of how many times something would probably happen for node at pos `pos` if the area was active and we didn't skip the nights.
It reads and updates meta variable `_t` from position `pos` and uses it as previous `seconds_irl`, so we don't need to remember it.
Argunments:
* `pos` - node position
* `interval` and `chance` - interval and chance like from ABM setup
Returns:
* Integer number of how many times something would happen to the node at position `pos` if the area was active all the time and we didn't skip the nights.
* For unclear conditions, like missing meta or zero `time_speed`, this function will return `nil`.
### mcl_time.get_irl_seconds_passed_at_pos(pos)
-----------------------------------------------
Returns the number of how many in-real-life seconds would be passed for the node at position `pos`, if the area was active all the time and we didn't skip the nights.
It uses node meta variable `_t` to calculate this value.
Argunments:
* `pos` - node position
Returns:
* Integer number of how many in-real-life seconds would be passed for the node at position `pos, if the area was active all the time and we didn't skip the nights.
* For unclear conditions, like missing meta or zero `time_speed`, this function will return `0`.
### mcl_time.get_irl_seconds_passed_at_pos_or_1(pos)
----------------------------------------------------
Returns the number of how many in-real-life seconds would be passed for the node at position `pos`, if the area was active all the time and we didn't skip the nights.
It uses node meta variable `_t` to calculate this value.
Argunments:
* `pos` - node position
Returns:
* Integer number of how many in-real-life seconds would be passed for the node at position `pos, if the area was active all the time and we didn't skip the nights.
* For unclear conditions, like missing meta or zero `time_speed`, this function will return `1`.
### mcl_time.get_irl_seconds_passed_at_pos_or_nil(pos)
----------------------------------------------------
Returns the number of how many in-real-life seconds would be passed for the node at position `pos`, if the area was active all the time and we didn't skip the nights.
It uses node meta variable `_t` to calculate this value.
Argunments:
* `pos` - node position
Returns:
* Integer number of how many in-real-life seconds would be passed for the node at position `pos, if the area was active all the time and we didn't skip the nights.
* For unclear conditions, like missing meta or zero `time_speed`, this function will return `nil`.
