Quick Start

Data Pack Quick Start

Create data/adaptive_nemesis/invasions/my_invasion.json:

{
  "max_waves": 3,
  "spawn_distance": 50,
  "rewards": {
    "experience": 100
  },
  "waves": [
    {
      "wave": 1,
      "difficulty_multiplier": 1.0,
      "enemies": [
        {"entity_type": "minecraft:zombie", "count": 3, "weight": 1}
      ]
    }
  ]
}

Trigger it with:

/an invasion trigger adaptive_nemesis:my_invasion

KubeJS Quick Start

Create kubejs/server_scripts/my_adaptive_script.js:

adaptive_nemesis.entity_scale(event => {
    if (event.entityId.includes("zombie")) {
        event.multiplyMultiplier(1.5);
    }
});

Run /kubejs reload. All zombies will now receive an extra 50% scaling.
