About this Mod

About

Server-side mod that lets you throw diamonds at the world border to increase its size over time. Designed for singleplayer and small servers.

  • Border Width per diamond - 1 block
  • Time to expand - 10 seconds

Throwing a stack of diamonds consumes it entirely, but the border cannot consume diamonds if it's currently growing.

Configuration

Default configuration at config/diamond_worldborder.json:

{
  "entries": [
    {
      "diamondId": "minecraft:diamond",
      "widthPerDiamond": 1.0,
      "timePerDiamondSeconds": 10.0
    }
  ]
}
  • Adding extra entries makes you able to use item1 or item2 etc, each with different width/speed values.
  • Numbers are of type double, so decimal point numbers like "widthPerDiamond": 0.3 are accepted.
  • widthPerDiamond can be set negative to make the border shrink instead.
