Throw diamonds (or other items) at the border to expand it.
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": 0.3are accepted. widthPerDiamondcan be set negative to make the border shrink instead.
