luatic: is there a way to convert a table to a string? In standard Lua there appears to be a `to_string()` function. |
| 01:21 |
Yad |
There seems to be a global `tostring()` function in Minetest. |
| 01:21 |
Yad |
And I do get some hexidecimal as a string when I use `minetest.chat_send_all(tostring(this_player:hud_get_flags()))` |
| 01:22 |
MTDiscord |
<Jonathon> if your debuging, use dump() |
| 01:22 |
MTDiscord |
<Jonathon> minetest.chat_send_all(dump(cursed_table_that_is_causing_me_trouble)) |
| 01:22 |
Yad |
Oooh, thanks! |

Is there currently only possible to have one moon? |

(Or could I theoretically rig the skybox to have more than one object move across the sky at night?) |
| 02:02 |
Yad |
I suppose the whole sky moves, so I could simply paint a single moon texture across the whole sky, the multiple moons simply would be unable to move at different speeds for different orbital radii. |
| 02:03 |
Yad |
*single texture showing multiple celestial bodies |
| 02:19 |
erlehmann |
Yad or you switch the skybox like a boss |
| 02:19 |
Yad |
erlehmann: :D :D :D |

| 02:21 |
Yad |
(probably my top feature desire is colored light sources) |
| 02:27 |
Yad |
erlehmann: I get a strange error about trying to perform arithmetic on a boolean when I use `minetest.chat_send_all(dump(this_player:get_sky()))` |
| 02:27 |
Yad |
as though `dump()` isn't compatible with the data structure? |
| 02:28 |
erlehmann |
i have no idea why you ask me, but try dump2 |
| 02:28 |
erlehmann |
like if dump() is not good enough, try dump2() |
| 02:28 |
erlehmann |
the dumpening |
| 02:28 |
erlehmann |
this is not a joke btw |
| 02:29 |
erlehmann |
also use minetest.debug() for debug stuff srsly |
| 02:29 |
Yad |
Oh, I asked you because you're active in the chat. :) I try to put names in my messages so I don't assume people are having a sound effect or other notification every time there is a message |
| 02:29 |
Yad |
And thank you, I was not familiar with `dump2()` |
| 02:30 |
MTDiscord |
<Jonathon> doesnt get_sky return multiple args? |
| 02:30 |
MTDiscord |
<Jonathon> and dump2 is for objects |
| 02:30 |
Yad |
Jonathon: "`get_sky()`: returns base_color, type, table of textures, clouds." |
| 02:30 |
MTDiscord |
<Jonathon> i can read the api as well as you can |
| 02:30 |
Yad |
Jonathon: Of course you can but I didn't want to assume you had it open. :) |
| 02:31 |
Yad |
Also reading it into the logs here. |
| 02:31 |
Yad |
As I hope there will be a more descriptive description in future versions of Lua_API.txt ^_~ |
| 02:31 |
Yad |
Which I will be happy to contribute once I understand better the function. :) |
| 02:31 |
MTDiscord |
<Jonathon> pack it in a table |
| 02:32 |
Yad |
Ooooh, yeah! |
| 02:32 |
MTDiscord |
<Jonathon> minetest.chat_send_all(dump({this_player:get_sky()})) |
| 02:32 |
Yad |
Indeed. ^^ So subtle, yet so effective. |
| 02:35 |
MTDiscord |
<Jonathon> if you get to be lazy like me, just have debug statement pasted at the top of your mod that is like function cout(...) minetest.chat_send_all(dump({...})) end and then you can be lazy testing in game with //lua and do //lua cout(thing) |
| 02:36 |

It's harmless but funny that dump() outputs color tables as r,b,a,g instead of r,g,b,a heheheh |
| 04:49 |
Yad |
I mean r g b can be in any order I suppose, but alpha is clearly a separate concept from primary colors |
| 04:50 |
Yad |
so to have it in the midst of them is an oddity |
| 04:50 |
MTDiscord |
<Jonathon> its dumping them in the order it finds the keys |
| 04:50 |
MTDiscord |
<Jonathon> there named so there is no defined order as compared to numerical keys |
| 04:50 |
Yad |
Jonathon: oooh, so the anomaly is in the C++ of Minetest? |
| 04:51 |
Yad |
Yeah, the labeling is what I meant by harmless :) |
| 04:51 |
Yad |
since they get addressed by label usually i'd imagine |
| 04:51 |
MTDiscord |
<Jonathon> there is no anomaly, and it would be in the C of lua |

Jonathon: Speaking of defined functions (or events) is there an equivalent of the `on_step` event for players? I only see it for entities. |
| 05:09 |
MTDiscord |
<Jonathon> on |
| 05:09 |
MTDiscord |
<Jonathon> *no |
| 05:09 |
MTDiscord |
<Jonathon> you have to use a globalstep and loop through all the players |
| 05:10 |
Yad |
Oooh, okay. Well that's better than having to attach an entity to the player to track steps. :) |
| 05:10 |
Yad |
(of course I do mean program steps not "footsteps" or something) |
| 05:10 |
MTDiscord |
<Jonathon> honestly, best way to do it depends on your usecase |
| 05:10 |
Yad |
yep, but thank you now I know there is a `minetest.register_globalstep(function(dtime))` |
| 05:11 |
MTDiscord |
<Jonathon> if your a game and multiple parts want to do stuff on step, your probably best building a core globalstep that adds in a on_step, and then every mod after that adds onto that on_step method |
| 05:12 |
Yad |
interesting |
| 05:13 |
Yad |
something I will probably understand better as I continue to experiment :) |
| 05:39 |
|
Yad joined #minetest |

Would this make any sense for checking if an entity is attached? `on_step = function(self) if self.ref:get_attach() ~= nil then` |
| 06:01 |
|
riff-IRC joined #minetest |
| 06:36 |

Of of course! It's supposed to be `self.object` just as when using `set_attach()` hahah |

Anybody know of a good learning example for custom skyboxes? I suppose it's my own weakness in Lua which makes it challenging to keep track of all the nested properties tables. xD |

Apparently colors need to be defined as their hexadecimal strings? |

Yad look at skybox handling in mcl2 or some better-written weather/dimension mods |

I thought it would be effective to study MineClone2 because that has different skyboxes depending on y-coords, but it has so much of its on infrastructure built on top of the base Lua API...oh hhahah hey :D |

set_sky actually able to take words as colors like that? |

not for long if zughy gets their will lol |

Yad i know literally nothing about this topic |
| 19:00 |
erlehmann |
please ask the author of the mod, sofar |
| 19:01 |
MTDiscord |
<luatic> set_sky now has a more advanced parameter format, but I guess the old format is still supported |
| 19:01 |
MTDiscord |
<luatic> you should use the new format though, in case they decide to remove the (possibly deprecated?) old format |
| 19:01 |
erlehmann |
luatic, yeah, but zughy is in the “make it backwards-incompatible even if you can afford to keep the 4 lines that implement it forever” club |
| 19:01 |
MTDiscord |
<luatic> about the colors: colorspecs can be colorstrings; colorstrings can be named colors |
| 19:02 |
erlehmann |
do we have a list of those colors? |

i mean i have used them |

but mor like |

<luatic> I want to know your RegEx now |

<luatic> Because if a RegEx can be applied, it is usually preferable over replicating RegEx functionality in code |

<luatic> Teckla ^ |
| 19:28 |
MTDiscord |
<luatic> NVM, in this case not using a RegEx is reasonable |
| 19:37 |
Teckla |
luatic: User supplied JS expression, it might be designed purposefully malicious, to cause a DoS in the regex (stack overflow, memory overflow, CPU pegged, etc.) |
| 19:56 |
erlehmann |
luatic you are missing rebeccapurple https://drafts.csswg.org/css-color/#valuedef-rebeccapurple |
| 19:56 |

Teckla a user supplied expression should NEVER be able to confuse a regular automaton |
| 19:57 |
erlehmann |
Teckla if that is even possible, you are probably using the wrong approach entirely |

not level 3 |

and have been saying that for a long time |

<luatic> Because that's what is in fact implemented |

independent56 |
Does minetest take mods and just stores it all in memory? If textures are stored as well, i'll go into panic. I can see a mod with loads of textures slowing servers. |
| 21:15 |
independent56 |
I hope textures are taken as needed and stored in the client's memory. |

<luatic> sfan5: the docs say https://github.com/minetest/minetest/blob/f2d1295fe646105f1b98b0c204f47f781336e211/doc/lua_api.txt which contradicts the state of the implementation, which is level 3 |

| 21:16 |
sfan5 |
okay but why are you pinging me on this |
| 21:17 |
MTDiscord |
<luatic> Because either the docs or the code needs a fix ^^ |
| 21:17 |
MTDiscord |
<luatic> (and depending on what the fix will be, I might have to update modlib) |
| 21:19 |
MTDiscord |
<luatic> independent56: There's media, and then there's code. I'm not quite sure whether the server loads all media into memory - it probably does - but that doesn't really matter as long as it stays in the megabyte range. Code size is negligible compared to that; compiled "chunks" will obviously reside in memory until Lua garbage collects them. Now what about textures? Texture modifiers are indeed generated as needed (and then cached forever). Not |
| 21:19 |
MTDiscord |
sure whether the same applies to base textures. |
| 21:19 |
MTDiscord |
<luatic> (the latter is clientside) |

Cool |
| 21:20 |

I forgot textures aren't 100*100 |
