is it possible to register a callback to do something when a specific node is loaded or unloaded? |
| 01:34 |
sofar |
what do you mean by "loaded"? as in mapblock emerge? |
| 01:34 |
air |
yes |
| 01:34 |
sofar |
what do you want to do with it? |
| 01:35 |
air |
register the node with the mod, and then unregister it when the mapblock is unloaded |
| 01:42 |
sofar |
and why do you want to do *that* |
| 01:42 |
sofar |
? |

trying to optimize a mod that calls minetest.find_nodes_in_area() on a very large area |

air: just got back from afk: why does your mod run minetest.find_nodes_in_area() on a very large scale? |
| 04:28 |
air |
not my mod, https://github.com/tenplus1/protector |
| 04:28 |
sofar |
yes, fine, but... why? |
| 04:29 |
air |
it scans for protector nodes in the area when you dig |
| 04:29 |
sofar |
ok, and you want to optimize it? |
| 04:30 |
air |
they are increasing protector radius on xanadu from 5 to 10, which scans 8 times the area |
| 04:30 |
air |
and some scans do a radius of 20 |
| 04:30 |
sofar |
I'd suggest a lua voxelmanip |
| 04:30 |
air |
what is that? |
| 04:33 |
air |
doesn't that mass update properties for many nodes? |
| 04:33 |
sofar |
doesn't need to, can just discard the data |
| 04:35 |
air |
I don't see anything in there that would help |
| 04:35 |
sofar |
oh, it's a huge gain |
| 04:36 |
sofar |
you can get 10^3 nodes of data in the same time as one |
| 04:36 |
sofar |
(close to) |
| 04:36 |
sofar |
and no jumps out of lua to look at the data |
| 04:36 |
air |
but then iterate all the nodes in lua instead of in c? |
| 04:36 |
sofar |
so lua can inspect and find the protector node without exiting it's contents |
| 04:37 |
sofar |
it's context* |
| 04:37 |
sofar |
iterate over the voxelmanip data in lua, yes |
| 04:37 |
air |
wouldnt it be faster to let C iterate over the nodes and return a small list of those it found, than to do the same in slower lua? |
| 04:42 |
sofar |
if your search is simple and find_nodes_in_area works for the use case |
| 04:44 |
sofar |
some search cases it may be slower, like if you wouldn't be able to search for a particular one node (but a combo of nodes) |
| 04:45 |
sofar |
I see where you're going though |
| 04:45 |
sofar |
instead of searching, you just want to have a known list |
| 04:47 |
air |
well, the list is optional since it produces garbage, but would the voxelmanip produce more garbage? |
| 04:48 |
sofar |
that's not what I meant |
| 04:48 |
sofar |
instead of having to search every single time when a person digs... why not store a list of known protector blocks? |
| 04:49 |
air |
that is what I wanted to do, but I don't see a way to get the nodes when the mapblock loads |
| 04:49 |
sofar |
lbm's can do that now |
| 04:49 |
air |
I could have stored them in an octree |
| 04:49 |
sofar |
just make them active on every load |
| 04:50 |
air |
what about when the mapblock unloads? |
| 04:50 |
sofar |
https://github.com/minetest/minetest/blob/master/doc/lua_api.txt#L3325 |
| 04:50 |
sofar |
can't, there's no event for unload |
| 04:50 |
sofar |
run_at_every_load = true |
| 04:50 |
air |
well, I saw lbms but useless if I can't unload |
| 04:51 |
sofar |
not really, it just may become a large octree |
| 04:51 |
sofar |
but you wouldn't ever need to store the octree offline :) |
| 04:51 |
sofar |
since after a server restart... having an emptry octree is just fine! |
| 04:51 |
sofar |
lbms will fill it again |
| 04:51 |
air |
it could consume all server memory too :) |
| 04:52 |
sofar |
if you just store pos, very unlikely |
| 04:52 |
air |
the octree itself would |
| 04:53 |
sofar |
would what? |
| 04:53 |
air |
use all the memory |
| 04:55 |
air |
if someone knew the mod was not unloading, they could place a single protector in as many mapblocks possible |
| 04:56 |
sofar |
aside the academic exercise |
| 04:57 |
sofar |
perhaps you should limit the amount of protectors a person may use |
| 04:58 |
air |
not my choice, I'm just trying to make it faster |
| 04:59 |
sofar |
if the risk of going OOM is too large, just use the node search |
| 05:00 |
sofar |
and find_node_* is implemented in C++ |
| 05:01 |
sofar |
so it would be low-memory, and c++ accelerated |
| 05:01 |
sofar |
a fairly good tradeoff |
| 05:01 |
sofar |
what does the code do now? |
| 05:02 |
air |
find_nodes_in_area? |
| 05:02 |
sofar |
yes, that's implemented in C++ |
| 05:02 |
air |
right, I'm trying to implement the voxelmanip right now to test speed |
| 05:20 |
air |
hehe, 3 nested for loops doing nothing at all take 12 times as long |
| 05:31 |
sofar |
https://forum.minetest.net/viewtopic.php?f=3&t=14262 maybe of use to folks |
