# Purpose & Overview

Crafty is written in Python.<br>
|
||||
|
||||
[This video](https://youtu.be/bAGTwBURBXc) is what made me interested.

```
|
||||
|
||||
# Port forwarding
|
||||
|
||||
You **must forward port 25565** on your firewall to your docker host
|
||||
if you want it world accessible.<br>
|
||||
[Here's](https://github.com/DoTheEvo/selfhosted-apps-docker/blob/master/_knowledge-base/port_forwarding.md) a detailed guide.
|
||||
|
||||
# Reverse proxy
|
||||
|
||||
Caddy v2 is used, details
|
||||
[here](https://github.com/DoTheEvo/selfhosted-apps-docker/tree/master/caddy_v2).</br>
|
||||
|
||||
The minecraft server itself does not need this, but plugins might.<br>
|
||||
Like lets say dynmap would answer at `map.example.com`
|
||||
|
||||
`Caddyfile`
|
||||
(insecure_https) {
|
||||
transport http {
|
||||
tls_insecure_skip_verify
|
||||
}
|
||||
}
|
||||
|
||||
crafty.example.com {
|
||||
reverse_proxy crafty:8443 {
|
||||
import insecure_https
|
||||
}
|
||||
}verse_proxy minecraft:8123
|
||||
}
|
||||
```
|
||||
|
||||
# Domain
|
||||
|
||||
Setup a DNS A-record for you subdomain - `minecraft.example.com`
|
||||
Will work fine if using default port `25565`<br>
|
||||
If you would want to use a different port, but also would prefer your users
|
||||
to not need to enter `minecraft.example.com:30108` then google
|
||||
"minecraft srv record" and you should find correct settings.<br>
|
||||

# Monitoring

|

# Plugins
|
||||
|
||||
**Plugins installation** - place the downloaded jar files in to
|
||||
`~/docker/minecraft/minecraft_data/plugins` and restart the container.
|
||||
|
||||
* [multiverse core](https://dev.bukkit.org/projects/multiverse-core)
|
||||
* [multiverse portals](https://dev.bukkit.org/projects/multiverse-portals)
|
||||
* [multiverse inventory](https://dev.bukkit.org/projects/multiverse-inventories)
|
||||
* [multiverse netherportals](https://dev.bukkit.org/projects/multiverse-netherportals/)
|
||||
* [EssentialsX](https://essentialsx.net/downloads.html) *(switch to stable tab)*
|
||||
* [EssentialsX Spawn](https://essentialsx.net/downloads.html)
|
||||
|
||||
Why the plugins?<br>
|
||||
You want one server but you want people to be able to play creative or surival?<br>
|
||||
Well you need `multiverse core`.<br>
|
||||
How do the people move between these worlds?<br>
|
||||
Well you need `multiverse portals`.<br>
|
||||
Should they be able to bring stuff from one world to another? No?<br>
|
||||
Well you need `multiverse inventory`.<br>
|
||||
Should the connecting of worlds with their nether be easy?<br>
|
||||
Well you need `multiverse netherportals`.<br>
|
||||
Should they spawn in lobby on start,
|
||||
but also remember the position in the worlds when entering portals?<br>
|
||||
Well you need the rest of that shit, `EssentialsX` and `EssentialsX Spawn`.
|
||||
|
||||
|
||||
|
||||
# The setup
|
||||
|
||||
check if the plugins are loaded using command `plugins`
|
||||
|
||||
### creation of the worlds
|
||||
|
||||
* check the worlds present - `mv list`<br>
|
||||
these 3 existing worlds [world, nether, end] are grouped and interconnected
|
||||
and will be used as the survival world
|
||||
* create a new world called **"creative_world"** - `mv create creative_world normal`
|
||||
* teleport to it - `mv tp creative_world`
|
||||
* switch mode to creative - `mvm set mode creative creative_world`
|
||||
* create a new world called **"lobby"** - `mv create lobby normal -t flat`
|
||||
* teleport to lobby world - `mv tp lobby`
|
||||
* remove monsters - `mvm set difficulty peaceful`
|
||||
* remove animals - `mv modify set animals false`
|
||||
* set adventure - `mvm set mode adventure`
|
||||
* **build 2 portals**, for survival and creative worlds
|
||||
* get worldedit axe using command - `mvp wand`
|
||||
* use left click and right click to select portal area<br>
|
||||
after selecting it create a portal named portal1 with destination creative_world -
|
||||
`mvp create portal1 creative_world`
|
||||
* same thing with the axe for survival, with destination to "world" -
|
||||
`mvp create portal2 world`
|
||||
* you can check your portals configuration on server in `> plugins > multiverse-portals > config.yml`
|
||||
* if **non OP players** cant use portals execute -
|
||||
`mvp conf enforceportalaccess false` or `mv conf enforceaccess false`
|
||||
|
||||
*bonus info*<br>
|
||||
if you have seed `mv create snow_world normal -s -5343926151482505487`
|
||||
|
||||
|
||||
### spawning in the worlds
|
||||
* pick a spawn point in the lobby and set it with multiple commands
|
||||
* `setspawn`
|
||||
* `setworldspawn`
|
||||
* `mv setspawn`
|
||||
* edit the file in `> plugins > Essentials > config.yml`<br>
|
||||
`setspawn-on-join: true`
|
||||
* you would think we are done with spawns, but nope, fuck you,
|
||||
this all lets the game start in spawn location in the lobby world,
|
||||
but when entering creative world you would be starting from its spawn,
|
||||
instead of last position on exit. So... heres how to fix that.
|
||||
* this command for the inventory plugin makes the world remember last location
|
||||
`mvinv toggle last_location`<br>
|
||||
but with just that change the lobby world position is also remembered
|
||||
and users end up spawning inside of portals instead of specific spawn
|
||||
* to fix that we set in `> plugins > multiverse-inventories > config.yml`
|
||||
`optionals_for_ungrouped_worlds: false`<br>
|
||||
* but our lobby world is ungrouped, so we need to add it to a group
|
||||
using command `mvinv group` and then following the instructions.
|
||||
Writing the answers in to the console without slash, when it asks
|
||||
about shares, giving `last_location` and ending with `@`<br>
|
||||
[This](https://i.imgur.com/8yBh2Bz.png) could be helpful too,
|
||||
but it feels like doing unnecessary steps
|
||||
* now you should have spawn point in lobby that is always the same,
|
||||
while after entering portals you end up at your last location
|
||||
|
||||
# Extra Plugins
|
||||
|
||||
* [AntiPopup](https://github.com/KaspianDev/AntiPopup) -
|
||||
if you dont want that stupid chat popup so thats AntiPopup.<br>
|
||||
* [Action Bar Health](https://www.spigotmc.org/resources/action-bar-health.2661/)
|
||||
- see mobs health when you fight them,
|
||||
in config I set `show on look` to false<br>
|
||||
I prefered the look of holomobhealth, but its dependancy ProtocolLib is only
|
||||
in beta at the moment, and might be causing issues on my server, did not investigate thoroughly
|
||||
* [Bluemap](https://www.spigotmc.org/resources/bluemap.83557/) - map
|
||||
of the world in web gui, real time.Default port 8100
|
||||
|
||||
----------
|
||||
|
||||
Something of this is causing server to ocasionally go to super high disk use
|
||||
and needs restart. Not just container, but entire VM. Will maybe investigate.
|
||||
|
||||
/update, it was likely caused by using m.2 ssd for storing esxi VMs,
|
||||
switch to sata ssd seems to prevent any more occurancies of this high disk usage
|
||||
|
||||
/update2, well since it started happening again, now it seems to be solved
|
||||
by setting up 6GB swapfile, which I.. err.. didnt think it needed.
|
||||
|
||||
* [Dynmap](https://www.spigotmc.org/resources/dynmap%C2%AE.274/) - map
|
||||
of the world in web gui, real time. Default port 8123
|
||||
* [Chunky](https://www.spigotmc.org/resources/chunky.81534/) - pre-generates chunks
|
||||
useful for dynmap to fill black patches
|
||||
* [OpeNLogin](https://www.spigotmc.org/resources/openlogin-1-7x-1-19x.57272/)
|
||||
* [luckperms](https://luckperms.net/download) - manage permissions of players,
|
||||
planned to use, not in use yet. [Here](https://www.youtube.com/watch?v=AwbVqSOn2SI) is a good video on it.
|
||||
|
||||
luckpers commands
|
||||
|
||||
* `lp editor` - open browser editor, afterwards it should be confirmed
|
||||
* set everything in browser
|
||||
* in game `lp user Dunco parent set hráč`
|
||||
|
||||
|
||||
* wordguard with word edit, followed [this video](https://youtu.be/pYAk38Hekqg)
|
||||
|
||||
# Comamnds & settings
|
||||
|
||||
* `/gamerule playersSleepingPercentage 1` - use bed whenever, sleep not dependant on other players
|
||||
* to import a map, download, extract, copy the directory to minecraft_data<br>
|
||||
`mv import <directory-name> normal`, there should be no spaces in the name
|
||||
* `/mv setspawn` sets spawn point in the current world
|
||||
|
||||
* [command block basics](https://www.youtube.com/watch?v=Mp3UJs9v2_0)
