KantoSpawners

KantoSpawners

KantoSpawners is a Fabric/Cobblemon utility mod that adds configurable spawner blocks for map makers, adventure servers, and controlled Cobblemon encounters.

This mod was originally created for the CobbleKanto project, where it is used to control encounter areas more precisely than normal biome spawning allows. It can also be used in other Cobblemon maps, servers, minigames, routes, dungeons, event zones, or adventure builds where you want specific species to appear in specific places.

Instead of relying only on biome spawns, KantoSpawners lets creators place a spawner block and configure exactly what it can spawn, how often it tries to spawn, what level range it should use, how many creatures can exist nearby, and whether the spawned creature should immediately start a battle.

What It Is For

KantoSpawners is designed for creators who want more control over encounter design.

It is especially useful for:

• custom routes
• caves
• forests
• event areas
• dungeons
• gyms
• boss rooms
• adventure maps
• server progression zones
• recreations or inspired regions
• controlled spawn areas in multiplayer worlds

The goal is not to replace Cobblemon’s natural spawning system, but to give builders and map/mod builders a direct tool for scripted encounters inside dungeons and routes.

How It Works

Place a Kanto Spawner in the world, open its editor, and configure the encounter rules.

The spawner can be configured with:

• species list
• spawn weights
• level range
• shiny chance
• spawn radius
• spawn delay
• nearby creature limit
• aggressive battle behavior

The spawner only tries to spawn when a player is nearby, which helps reduce unnecessary background activity in empty areas + help triggering the "Aggressive" mode.

Spawned creatures are also given return behavior so they do not wander too far away from their intended encounter zone.

Fields

Min Level

The lowest possible level for spawned creatures.

Max Level

The highest possible level for spawned creatures.

Shiny Chance (%)

Chance for a spawned creature to be shiny.

Example:

1

means 1%.

Spawn Range

How far from the spawner the creature can appear.

Spawn Delay (ticks)

How often the spawner attempts to spawn.

Minecraft runs at 20 ticks per second, so:

100

is about 5 seconds.

Max Cobblemon in Range

The maximum number of Cobblemon entities allowed near the spawner before it stops spawning more.

Species List

A weighted list of species using this format:

pidgey:50,rattata:30,caterpie:20

The numbers act as weights, not strict percentages. Higher numbers make that species more likely to be selected.

---

Aggressive?

When Aggressive? is enabled, the spawner can start a PvE battle between the nearest player and the spawned creature.

This is useful for:

• ambush encounters
• trainer-like wild encounter areas
• dungeon rooms
• challenge paths
• event encounters
• controlled battle zones

Aggressive mode is optional. For normal ambient encounters, leave it disabled.

Behavior Notes

KantoSpawners includes a few safety behaviors designed for adventure maps and multiplayer servers.

Nearby Player Requirement

The spawner only attempts to spawn when a player is nearby.

This prevents inactive map areas from constantly generating entities.

Nearby Spawn Limit

The Max Cobblemon in Range setting prevents too many Cobblemon entities from stacking up around the same spawner.

Return-to-Spawner Behavior

Spawned creatures are encouraged to return toward their spawner if they move too far away from the configured range.

This helps keep routes, rooms, caves, and encounter zones from slowly leaking spawns into unrelated areas.

Spawn Position Logic

The spawner tries to find a valid floor near the spawner height instead of simply spawning entities anywhere in the column.

This helps avoid creatures appearing on ceilings, far above the intended route, or in invalid spaces.

Optional Compatibility

Jade

If Jade is installed, KantoSpawners can show spawner configuration information through its HUD tooltip.

This is useful for admins who want to quickly inspect configured spawners while building or debugging a map.

KantoItems Repel Compatibility

KantoSpawners includes a compatibility hook for the KantoItems Repel effect.

If that effect exists and the player has it active, aggressive battle behavior is prevented.

KantoItems is not required to use KantoSpawners.

KantoNPCs Dialog Protection

KantoSpawners also includes a lightweight protection hook for KantoNPCs dialogue/battle flow.
