Configuration

• Config file is stored as config.json under lattice in the server config directory
• You can change the time when the end or the server will be opened
• MOTDs and a list of illegal mods can be configured
• Each player has configurable options:
  • PvP enabled/disabled
  • Nickname
  • Status message
  • Rules enabled/disabled

Configuring the rulebook

To configure the rulebook, you need to manually edit the config.json file. Example:

"rules": [
"{\"text\":\"Rule 1\",\"color\":\"aqua\"}",
"{\"text\":\"Rule 2\",\"color\":\"red\"}",
"{\"text\":\"Rule 3\",\"color\":\"aqua\"}",
"{\"text\":\"Rule 4\",\"color\":\"blue\"}",
"[\"\",{\"text\":\"Do you accept these rules?\\n\"},{\"text\":\"[\\u2713]\",\"color\":\"green\",\"click_event\":{\"action\":\"change_page\",\"page\":10000}},{\"text\":\" \",\"color\":\"reset\"},{\"text\":\"[\\u2717]\",\"color\":\"red\",\"click_event\":{\"action\":\"change_page\",\"page\":5000}}]"
]

Each entry in the rules array is a JSON object.
You have to use a JSON text component for each rule.
I recommend using this website to create it easier, but do keep in mind that the generated JSON will need some adjustments to work properly in the config file.
For example, the website generates a click event as clickEvent but it needs to be click_event in the config file.
You can also modify what the player should click to accept or decline the rules by going to a page with a high number ( e.g., 10000) and a low number (e.g., 5000) respectively.

Known issues

• The hopper sort doesn't work with lithium's hopper optimizations enabled. Please disable them in the lithium config if you want to use hopper sorting. Add this to config/lithium.properties:

mixin.block.hopper=false
