Debuff Zones
Adds a softer alternative/add-on to the vanilla worldborder system.
Usage
Edit the configuration file in config/debuffzones.json. Each element in the zones array represents one zone object, which has the following syntax:
{
"dimension": "minecraft:overworld", // The dimension where this zone applies
"center": [
0.0, // Center X
0.0 // Center Z
],
"distance_type": "SQUARE", // can be SQUARE or CIRCLE
"radius": 1000.0, // Radius (either Euclidean distance or distance on either axis, with the type CIRCLE and SQUARE respectively)
"effects": [ // List of "effect instance" objects
{
"identifier": "minecraft:slowness", // Effect ID
"potency": 1, // Effect level (starting from 0)
"time": 10, // The duration of the effect (generally doesn't matter, it's applied each tick but some laggier servers may benefit from a higher value here)
"ambient": true, // Makes swirls *less* visible (like beacons)
"particles": false, // Makes swirls *not* visible
"show_icon": true // Makes the icon show in the top right
}
],
"damage": 0.0, // How much damage should happen each tick
"difficulty": 0.0 // This is added on to the clamped regional difficulty (see https://minecraft.wiki/w/Difficulty#Regional_difficulty)
// NOTE: Regional clamped difficulty is a value from 0.0 - 1.0, so values above this won't change anything.
"regeneration_bypass": false // If having Regeneration should disable this zone's effects
}
