Hi everyone. Huge question. I'm currently on a Minetest server and I have my area protected (the server uses "Areas" mod). There is a player, without any special privileges, he is able to walk righ through protected walls!!! How is this possible? |
| 11:02 |
Markow |
I asked him and he said it is a "glitch" which allows him to do this, but he will not tell me how it is done |
| 11:03 |
Markow |
He walks through any protected area through the walls. I have no idea how this is being done. |
| 11:04 |
Markow |
This player is unable to destroy my protected blocks though. He can only "walk through" them |
| 11:05 |
Markow |
The only "privs" we have are: fast home interact money shout |
| 11:10 |
Markow |
The server version being used is 5.0.1. My MT client is 5.3.0. |
| 11:10 |
Markow |
Is it possible a server version that old has the glitch I mentioned? |
| 11:13 |
Markow |
I notice that this player "punches" the blocks in the protected area and just walks right through it |
| 11:14 |
Markow |
But the blocks are not destroyed |
| 11:21 |

can 1 node of water stop fall damage from 100 blocks or so? I died and I want to know if I hit the edge of the next node or if the water was the problem |
| 11:21 |
bdju |
I'm using dynamic liquids in case that matters |
| 11:24 |
Markow |
Oh well, everyone must be either busy or sleeping, or working |
| 11:25 |
bdju |
yes probably (sorry I don't know about your problem btw) |

Markow: The client predicts that the node will be destroyed, and it's possible to sneak through before the server can correct it. |

Markow |
luk3yx: But how is that player able to do it, and I canno do it. We have the same privs. |
| 12:11 |
Markow |
I asked that player how it is being done. No explanation, silence. |
| 12:15 |
luk3yx |
Markow: Latency |
| 12:15 |
Markow |
How is it controlled? |
| 12:15 |
Markow |
What timing is used? |
| 12:16 |
luk3yx |
If you're closer to the server it will take less time for the correction to be sent to your computer |

luk3yx: why doesen't the server correct the player's position as well? |
| 12:22 |
Markow |
I don't think that player runs the server. But being close enough to it is sufficient to take advantage of the latency? |
| 12:23 |
specing |
maybe they modified the latency? |
| 12:23 |
specing |
it's possible to tell your OS to delay minetest's packets by a few seconds |
| 12:23 |
specing |
you could try it out yourself |
| 12:23 |
Markow |
Ah, yes, with Iptables |
| 12:25 |
specing |
no, with qdisc |
| 12:25 |
Markow |
Thanks for the response. It's hard to believe the lengths some players go through just to compromise a game |
| 12:25 |
specing |
I haven't tried this myself |
| 12:25 |
specing |
you should 1) file a bug 2) tell the admins to ban that player |
| 12:26 |
Emerald2 |
It's annoying when they do that. I've seen people turn off and on their wifi to break into secured areas on some servers. |
| 12:26 |
Emerald2 |
And yeah, if there's enough lag you can straight up dig through some walls and get through before the blocks get replaced. |
| 12:27 |
Markow |
I wonder if there is a way in MT to prevent that, or in the mod? |
| 12:28 |
* Emerald2 |
shrugs. |
| 12:28 |
Emerald2 |
Above my paygrade. ;) |
| 12:28 |
specing |
if the server doesen't check player position for correctness then you could just program an arbitrary teleport command into the client |
| 12:28 |
specing |
no need to lagbreak walls |
| 12:28 |
Markow |
Would be a nice workaround to fix in MT, if possible |
| 12:30 |
Markow |
Well, at least the player wasn't allowed to destroy the blocks, that is important, to prevent griefing. |
| 12:32 |
Emerald2 |
Position correction is tricky though. Add in lag and it starts throwing players around the place. |
| 12:32 |
specing |
yes, I'm mostly concerned with chests and dig protection working |
| 12:32 |
Markow |
But still, some privacy is nice when you get these kids in your face, not leaving you alone during gameplay. |
| 12:33 |
Markow |
They just follow you around, everywhere you go |
| 12:33 |
Emerald2 |
I had that problem on some servers. |
| 12:33 |
specing |
knockback is also broken in minetest. You can get armor, find a rat and a wall. And the rat attacks will push you until you end up INSIDE the wall |
| 12:33 |
specing |
and you will take damage from being inside the wall. And you will have to dig yourself out |
| 12:34 |
Markow |
Overall though, "areas" mod is a great one. Essential to avoid griefers. |
| 12:34 |
Emerald2 |
And much simpler than placing protection blocks all over your build. |
| 12:36 |
Emerald2 |
And certainly less ugly. :) |
| 12:39 |
Markow |
Is there a mechanism in MT for the server owner to see the IP addresses of those who join? |
| 12:39 |
Markow |
Or that must be done using standard Linux CLI commands? |
| 12:44 |
sfan5 |
specing: you can indeed teleport to arbitrary locations provided the elapsed time matches player walk speed |
| 12:45 |
specing |
that's a serious bug, then |
| 12:46 |
sfan5 |
also the issue you're describing with knockback and a wall sounds like a bug in the mob mod |

I wonder how much work it would be to allow setting a damage group for the damage_per_second of a node |
| 14:07 |
balirt |
currently, one can only differ between the node types that cause the nodedamage by checking for the "reason=node_damage" in the "minetest.register_on_player_hpchange" callback |
| 14:07 |
balirt |
and then checking the surrounding nodes and guessing which node caused it |
| 14:08 |
sfan5 |
guessing? doesn't the damage table give the name of the node? |
| 14:08 |
balirt |
the amount of damage doesn't need to be guessed, but I want to have the information on which node caused the damage |
| 14:09 |
balirt |
so I can both make the cactus collision box yield a constant damage, and prevent the constant damage from it when sam wears iron shoes |
| 14:09 |
balirt |
it all comes back to the cursed cactus issue, and the lack of on_contact events |
| 14:09 |
|
Anulo2 joined #minetest |

but having a more general method in c++ would be nice since querying over the environment blocks of all players (or entities) at each on_step is kind of excessive |
| 14:11 |
balirt |
imagine wanting to make a skeletonmob have that damage, and requiring to check each creeper's surrounding blocks every step |

I was reading in https://rubenwardy.com/minetest_modding_book/lua_api.html and I guess it claims it's outdated for a reason |
| 14:17 |
sfan5 |
there's https://minetest.gitlab.io/minetest/ which is up to date |
| 14:17 |
sfan5 |
but it's not on a single page, somewhat inconvenient |
| 14:18 |
balirt |
I had that bookmarked but switched to the old one for precisely this convenience :D |
| 14:20 |
balirt |
well with that solution, I can't think of any ungrateful complaints anymore |
| 14:20 |
balirt |
you guys really fix/enhance everything eventually |
| 14:21 |
sfan5 |
eventually |
| 14:21 |
balirt |
only takes a few decades at most |
| 14:23 |
balirt |
maybe in 20 years we'll have custom tool animations and animated pictures in HUD and item textures |
| 14:23 |
balirt |
at that point we can basically call it an unreal engine-lite |
| 14:24 |

and rebuild AAA games of 2020 inside |

in other words, make a render command dependent on the player ID |
