Throw diamonds (or other items) at the border to expand it.
Server-side mod that lets you throw diamonds at the world border to increase its size over time. Designed for singleplayer and small servers.
Throwing a stack of diamonds consumes it entirely, but the border cannot consume diamonds if it's currently growing.
Default configuration at config/diamond_worldborder.json:
{
"entries": [
{
"diamondId": "minecraft:diamond",
"widthPerDiamond": 1.0,
"timePerDiamondSeconds": 10.0
}
]
}
double, so decimal point numbers like "widthPerDiamond": 0.3 are accepted.widthPerDiamond can be set negative to make the border shrink instead.
