i keep seeing a lot of these messages lately on our server (0.4.17) |
| 00:27 |
tuedel |
ServerEnv: Trying to store id = 0 statically but block (0,35,0) already contains 2070 objects. |
| 00:28 |
tuedel |
how can i print the objects inside that mapblock to see what's going on? |
| 00:29 |
paramat |
maybe go to the block to see what's going on? multiply those block coords by 16 to get the node coords |
| 00:32 |
paramat |
if there is an excess of objects in a mapblock MT can't store them all in the database and prints that message |

cheapie, what happened with colored box and unified dyes? |
| 01:23 |
cheapie |
GreenDimond: What do you mean by "colored box"? I have a few mods that fit that description. |
| 01:23 |
GreenDimond |

GreenDimond |
plastic box |
| 01:24 |
GreenDimond |
my brain isnt functioning today |
| 01:24 |
cheapie |
And what's the problem with it? |
| 01:24 |
GreenDimond |
cut boxes cant be dyed |
| 01:24 |
cheapie |
That's always been the case, AFAIK. |
| 01:25 |
GreenDimond |
But why? |
| 01:25 |
GreenDimond |
The normal node can be dyed, the cut nodes just need a param2 value as well |
| 01:25 |
cheapie |
Because sharing param2 between facedir and color, while possible, is a massive pain in the butt. |

i have just been experimenting with deleteblocks. |
| 07:19 |
rodskagg |
originally i thought it would delete blocks, leaving air, but it didn't do that. |
| 07:19 |
rodskagg |
at first i thought it wasn't working. |
| 07:20 |
rodskagg |
later, i dug some holes and made a building. then used deleteblocks nearby. |
| 07:20 |
rodskagg |
i was surprised to noticed my hole and house were gone. |
| 07:20 |
rodskagg |
everything had returned to the way it had been originally. |
| 07:21 |
lumberJ |
rodskagg: you deleted map blocks no nodes |
| 07:21 |
rodskagg |
lumberJ: it filled in holes too. |
| 07:21 |
lumberJ |
meaning you basically reverted that block of the map back to its original state |
| 07:22 |
rodskagg |
lumberJ: so the original untouched map data is always there? and everything that people add or subtract is recorded separately? |
| 07:22 |
rodskagg |
deleteblocks basically removes new stuff. showing the orginal map? |
| 07:23 |
lumberJ |
not sure exactly how it works, but i'm guessing it refers back to the mapseed and the way in which the orginal map is generated |
| 07:23 |
lumberJ |
and regenerates that block as such |
| 07:23 |
rodskagg |
ooooh. |
| 07:23 |
rodskagg |
yeah, that would make sense. |
| 07:24 |
rodskagg |
so deleteblocks just recalculates a certain area again. |
| 07:24 |
rodskagg |
that is so cool. |
| 07:24 |
lumberJ |
yeah, its come in handy for me, but as you have seen its potentially destructive |
| 07:24 |
rodskagg |
if you have a map and someone makes an ugly mess, you just fly in, deleteblocks the area and that part of the map is regenerated. |
| 07:25 |
rodskagg |
lumberJ: luckily i have .minetest under revision control. i'll just roll back. :) |
| 07:25 |
lumberJ |
yes, a lot quicker than trying to clean everything up as long as nothing else is nearby you are worried about |
| 07:25 |
rodskagg |
lumberJ: what a fantastic tool. |
| 07:26 |
rodskagg |
without that maps would get old and messy. |
| 07:26 |
rodskagg |
but with deleteblocks you are free to regenerate as many times as you want. |
| 07:26 |
rodskagg |
i love it. :D |

worldedit is powerful stuff |
| 07:30 |
rodskagg |
i wish minetest had a console where you could import text files of commands, like i used to in autocad. :) |
| 07:31 |
rodskagg |
minetest uses lua scripts, is that correct? |
| 07:31 |
lumberJ |
yes |
| 07:31 |
lumberJ |
worldedit takes lua commands |
| 07:31 |

cheapie: thank you so much. i will have fun with this. :) |
| 07:33 |
lumberJ |
keep those backups safe ;) |
| 07:33 |
cheapie |
They might need to be in the world directory to stop mod security from throwing a fit. Dunno for sure. |
| 07:34 |
lumberJ |
yeah, was going to say, i think world edit puts some restrictions on the scripts you run, but you should be able to do most things you would actually have a valid use case for |
| 07:34 |
rodskagg |
cool. |
| 07:34 |
cheapie |
lumberJ: The restrictions come from MT itself, via mod security. |
| 07:35 |
cheapie |
Of course, you can always turn mod security off... |
| 07:35 |
rodskagg |
i want to help my nephew get into coding. this would be perfect. |
| 07:35 |
lumberJ |
was thinking there were some additional protections built in but i could be confusing it with another mod |
| 07:35 |
rodskagg |
we need to work on python, because it's what he is studying at school. we could write python scripts that generate lua. |
| 07:36 |
lumberJ |
its been a while since i've really looked at it |
| 07:36 |
cheapie |
Nah, as long as you have the server and worldedit privs, //lua will let you run anything you want. |

but nothing to stop you from generating mods that way if you want :) |
| 07:37 |
cheapie |
Well, good luck :P |
| 07:37 |
lumberJ |
probably be a lot easier to just learn lua though |
| 07:37 |
rodskagg |
cheapie: if i teach him python scripts that make stuff happen in minetest he would love that. |
| 07:38 |
lumberJ |
why not teach him lua scripts instead? |
| 07:38 |
cheapie |
FWIW, this is the sort of stuff mods can do if you completely disable mod security *and* some of your OS's security :P https://www.youtube.com/watch?v=jf_ZC346lEM |
| 07:38 |
rodskagg |
because he needs python for school. |
| 07:38 |
cheapie |
(turn your volume up, my phone microphone sucks) |
| 07:38 |
rodskagg |
i am looking at good visual feedback for python coding. |
| 07:39 |
rodskagg |
to make it easier for him. |
| 07:39 |
rodskagg |
metacoding lua with python ticks all the boxes. |
| 07:39 |
rodskagg |
he'll obviously pick up a bit of lua as we go along. |
| 07:39 |
rodskagg |
but python is the objective. |

it will be so nice to get my nephew from using proprietary minecraft to open source minetest. he is super into the computer club at his school and if i can get him doing cool stuff in minetest then he will get his classmates using it too. :) |
| 07:51 |
lumberJ |
that'd be good. just introduce him to some good mods to get started with |
| 07:52 |
lumberJ |
if they are comparing minecraft to a vanilla mt_game they may be underwhelmed |
| 07:53 |
lumberJ |
at least that was my experience teaching kids using mt |
| 07:55 |
rodskagg |
lumberJ: i like how minetest has stayed minimal, as a blank canvas for mods to run on. it is a good model. |
| 07:55 |
lumberJ |
i do too personally, but little kids don't understand that |
| 07:55 |
rodskagg |
i will experiment with some mods before i introduce him. make sure it is fun. :) |
| 07:56 |
rodskagg |
then teach him how to install and run mods himself. :) |

lumberJ |
yeah, the kids have a way of digging around in the mod files and finding the license though |
| 08:00 |
lumberJ |
just something to look out for |
| 08:00 |
lumberJ |
i think that license is not in the actual game or default game mods anymore but i might be mistaken |
| 08:00 |

but its around in the community mods fairly commonly |

probably needs to be in a loaded mod or your world folder rodskagg, otherwise you will have mod security issues |
| 10:17 |
rodskagg |
makes sense |
| 10:18 |

you can request an insecure environment to act outside of those areas, but probably not worth the hassle unless their is pressing reason to access files elsewhere |

if you're using 5.0.0-dev, then you can enable the itemname tooltip setting so that you can see the name of each item stack as soon you hover over them |

i'm still looking for a way to list the objects stored inside a specific mapblock |
| 13:11 |
tuedel |
i've been seeing a lot of these messages lately: ServerEnv: Trying to store id = 0 statically but block (0,35,0) already contains 2215 objects. |
| 13:12 |
tuedel |
at these (mapblock) coordinates i've been trying to build a spaceship using https://github.com/thomasrudin-mt/jumpdrive |
| 13:13 |
tuedel |
so i'm suspecting some entities are getting duplicated while jumping back and forth |
| 13:15 |
tuedel |
gdb is already attached, i'm just not sure where to look |
| 13:18 |
Krock |
it's a mod issue |
| 13:19 |
Krock |
it spawns too many entities. use minetest.get_objects_in_range (or similar) to get a list of them |
| 13:25 |
VanessaE |
Krock: no, it's an engine issue, too |
| 13:26 |
VanessaE |
2215 is WAY WAY more than the engine should have been able to store -- notice it "already contains", not "wants to store" or so. |
| 13:26 |
VanessaE |
default is what, 49? |
| 13:26 |
VanessaE |
even my servers cap out at 500 per. |
| 13:26 |
VanessaE |
if the engine allows more than the configured max, it's a bug in the engine. |
| 13:26 |
VanessaE |
whether or not a mod is trying to add too many |
| 13:27 |
VanessaE |
which is also a mod bug |
| 13:27 |
Krock |
VanessaE: that means there were many entities generated within a short period of time |
| 13:27 |
Krock |
mod bug |
| 13:27 |
Krock |
it allows more because it might be temporary |
| 13:28 |
VanessaE |
Krock: but the engine successfully stored more than the configured max.. what's the point of having a max if a mod is allowed to disregard it? |
| 13:28 |
tuedel |
i've upped max_objects_per_block due to massive pipeworks constructions |
| 13:28 |
VanessaE |
Krock: remember, these stored entities are persistent across reboots |
| 13:28 |
Krock |
huh? it doesn't store them |
| 13:28 |
VanessaE |
yes it does. |
| 13:28 |
Krock |
bug |
| 13:29 |
VanessaE |
tuedel: afaik pipeworks no longer uses static/stored entities |
| 13:29 |
tuedel |
at that point max_objects_per_block was set to 2048 |
| 13:29 |
VanessaE |
however, I know the LCD in digilines mod had an entity leaking problem |
| 13:29 |
VanessaE |
maybe that's the source of your issue |
| 13:30 |
VanessaE |
(pretty sure the leak has since been fixed, I think by GreenDimond) |

fixed inside the engine or the mod? |
| 13:30 |
VanessaE |
in the mod. |
| 13:31 |
tuedel |
so an upgrade to 5.0-dev probably won't magically fix everything? :) |
| 13:31 |
VanessaE |
no. |
| 13:32 |
VanessaE |
afaik 5.0.0 hasn't much effect on entities. |
| 13:32 |
VanessaE |
update all of your mods from their upstream repos |
| 13:32 |
VanessaE |
(make sure you get them right) |
| 13:32 |
VanessaE |
I dunno about display_modpack though; LCD's problem was that it would re-create its text entity every time it's updated, even if the mapblock containing the LCD isn't loaded yet, and then the engine would reload the stored entit[y|ies] as well, leading to a leak. |
| 13:32 |
VanessaE |
isn't fully-loaded yet* |
| 13:33 |
VanessaE |
LBMs would trigger as soon as the mapblock terrain data is loaded, but before the entities stored there have been loaded |
| 13:35 |
VanessaE |
Krock: can you tell I've been around the block a few times regarding tuedel's "already contains" messages? :) |

for digilines i'm currently using https://github.com/12Me21/digilines after running into issues with duplicate messages |
| 13:37 |
VanessaE |
tuedel: now all of that said, 5.0.0 does seem to work okay now, in general |
| 13:37 |
VanessaE |
Krock: ? I have no question. |
| 13:37 |
VanessaE |
tuedel: that's not the upstread digilines...... |
| 13:37 |
VanessaE |
upstream* |
| 13:38 |
Krock |
well, there's a question mark |
| 13:38 |
VanessaE |
Krock: oh. that was a rhetorical question; the implied answer is "yes". :) |
| 13:38 |
tuedel |
yes, i'm aware of that. switching back to upstream would break my build because of the duplicate messages |
| 13:39 |
Krock |
ah, because I didn't get what you meant there lol |
| 13:40 |

does digilines/mesecons_luacontroller use objects to handle events? |
| 13:40 |
VanessaE |
idk, tuedel. |

but back to my original question. if try to use get_objects_inside_radius to find the objects causing this, it returns a lot of userdata objects which can't be serialized using minetest.serialize() |
| 13:45 |
tuedel |
i can call object:get_luaentity() for each, but many of them don't seem to have names |
| 13:46 |
tuedel |
so i'm looking for a way to print as much information as possible |
| 13:46 |
Krock |
get_luaentity().name or something like that |
| 13:46 |
Krock |
dump() should now also print userdata (as of 5.0.0-dev) |
| 13:47 |
sfan5 |
tuedel: in case you haven't figured stuff out yet: |
| 13:47 |
tuedel |
yes, it's nil for many objects |
| 13:47 |
sfan5 |
https://gist.github.com/sfan5/52917a0e1338bcda2176edbc416dae60 can read mapblock data and display entities contained |
| 13:47 |
sfan5 |
there's even a script that does so for the N largest mapblocks in your db |
| 13:47 |
sfan5 |
but you can just feed it data from a specific position |
| 13:48 |
tuedel |
sfan5: awesome, this seems to be exactly what i'm looking for |
| 13:49 |
tuedel |
i'll give it a try |

I'm writing a mod that needs to protect an area. I see the register_on_protection_violation, is_protected, record_protection_violation, and is_area_protected functions, but I'm having difficulty seeing what I would use to actually mark an area as protected. |
| 20:42 |
makayabou |
maybe you should use existing mod for that : https://forum.minetest.net/viewtopic.php?t=7239 |
| 20:44 |
makayabou |
for example, you type /area_pos set and punch the two corner nodes to set them (from https://github.com/ShadowNinja/areas/README) |
| 20:45 |
argyle77 |
Thank makayabou. I'll have a look at that code and see how they do it there. |
| 20:48 |
argyle77 |
Oh, I think I see it. I think I just have to override the is_protected function globally and determine if I'm protecting that position in there. |

| 21:11 |
argyle77 |
Thanks Krock. I'm actually confused now why there is a separate register_on_protection_violation function. It seems to me that the stuff you'd put in there could have just been placed in your overrided is_protected function. |
| 21:12 |
Krock |
it's not directly the same |
| 21:12 |
Krock |
in some places you only want to check whether it's protected. punishing the player (record violation) is another usecase |
| 21:13 |
|
Lone-Star joined #minetest |
| 21:13 |
Krock |
but I see that the API design there is confusing. one is a callback and the other a function to overwrite |
| 21:14 |
argyle77 |
The callback would always be called if the overrided function returns true, right? |
| 21:14 |
Krock |
only if it's called by mods or the Lua builtin code |
| 21:15 |
Krock |
for example, node placement and digging will execute the callback |
| 21:15 |
Krock |
but opening a shared chest (from other mods) which uses is_protected - won't. |
| 21:15 |
argyle77 |
But just checking is_protected won't necessarily cause a violation? |
| 21:15 |
Krock |
exactly |
| 21:16 |
Krock |
it's up to the mods to decide whether a failed is_protected check should result in a violation |
| 21:16 |
Krock |
since the mod might use it internally for random item placement which is accessible to the current player |
| 21:17 |
Krock |
or the sapling protection overlap check: minetest_game returns a chat message if you cannot place the sapling |
| 21:18 |
Krock |
the check is performed by doing many is_protected checks inside the given volume - recording a violation for each would not make sense |
| 21:19 |
argyle77 |
Ah that would be a good reason for their separation. |
| 21:22 |
argyle77 |
But if is_protected returns a true, and register_on_protection_violation is only called once for a set of those... How does the engine know when it is appropriate to make the callback and when not? Is that just a decision made in the is_area_protected function? |
| 21:23 |
argyle77 |
Can a mod (and how) return the differentiation between when a node is protected, and when a violation has occurred? |
| 21:24 |
rodskagg |
i have been using minetest.set_node( in a lua script and it is pretty cool. is there a list of other worldedit lua commands? |
| 21:25 |
Krock |
argyle77: I don't understand your question. If the violation callback is executed, then it's very likely after a is_protected call |
| 21:26 |
Krock |
rodskagg: with /lua you're executing Minetest API functions. It's not related to worldedit |
| 21:26 |

ah, got it. |

Don't worry about it. I may be asking a question without understanding some of the terminology, but I'm close to having a working experiment that will answer the question. |
| 21:28 |
Krock |
dump() will.. well.. dump the table into a readable string |

if you run Minetest from the console/terminal window, then you can also use print(dump( <data> )) |

argyle77: that's been an issue for a long time and there's no fix for it, save for using actually unbreakable nodes in the first place |

It seems like if the contingency replacement for a dug block was an ignore block until the server agreed, could this fix the issue? |

If you can point me in the direction of where blocks get dug on the client side, I'll have a look at the code. |
| 22:22 |
p_gimeno |
wouldn't that mean that you have to wait for the server to respond while e.g. digging tunnels? |
| 22:26 |
sofar |
the client predicts node digs |
| 22:27 |
sofar |
it has an idea of each node that allows it to assume some nodes are diggable |
| 22:27 |
sofar |
later on the server may correct it |

I dunno p_gimeno. If you can dig through ignore nodes, it would probably mainly mean that you'd have to wait for the server response to move forward, but not necessarily to dig further. |
| 22:43 |
argyle77 |
sofar, if the server makes a correction that a node isn't diggable, shouldn't the player's position be reset? |

rodskagg 'deleteblocks' will regenerate all entire mapchunks (80^3 nodes) that intersect with the requested 'deleteblocks' volume, so regeneration can happen up to 80 nodes away |
| 23:40 |
paramat |
the command description may need added warnings |
| 23:40 |
paramat |
it's misleading too |
| 23:42 |
paramat |
the requested mapblocks are deleted, but then mapgen sees the gaps and thinks 'that needs generating!' and generates entire mapchunks to fill the gaps |
| 23:44 |
paramat |
also "map blocks" may be misinterpreted as 'nodes', bad documentation |
| 23:44 |
paramat |
should be 'mapblocks' |
