How to adjust structures spawn frequency :
You are allowed to edit the mod file and redistribute it to friends for a server.
Open the mod file with the editor of your choice (WinRar for exemple), and look for this folder :
- data/cobblemonextrastructures/worldgen/structure_set
In it, you will find every structures as a json file. Open it with the editor of your choice, works with notepad, and change these values :
- "weight" is the chance of the structure to spawn among the list of structures that can spawn in this biome
- "spacing" is the average distance in chunks between two attemps to generate the structure, the lower it is the more likely the structure will spawn
- "separation" is the minimum distance in chuks between two attempts to generate the structure, must be lower than "spacing"
To change the biome the structure can spawn in, look for :
- data/cobblemonextrastructures/worldgen/structure
Look for the "biomes" key. You can change it to either an id like "minecraft:forest" or a tag like "#cobblemon:is_forest". The structure will only spawn in the specified biome(s).
How to adjust Pokemon respawning : (Neoforge only)
Pokemons now respawn inside structures after you catch or K.O. them. After launching Cobblemon Extra Structures for the first time, you will be able to find a config file inside your minecraft folder at :
- config/cobblemonextrastructures-common.toml
Inside it, you will be able to adjust how often Pokemon respawns. For structures like the Bell Tower, with unique spawns, the default value is 168000 ticks, which is 7 Minecraft days. For structures like the Dragon's den, with different encounters, the default value is 24000 ticks, which is 1 Minecraft day. You can set the value to -1 to disable respawns.
Note on Cobblemon Extra Structures for Fabric :
I was unable to get the new spawner blocks to work on fabric. Pokemons still appear, but they are generated with the structure only once. They won't have random IVs, a defined movepool or a chance to be shiny. I am sorry about that, I tried but I despise Fabric.
If you whish to help develop the Fabric version, the github link is open. I would gladly appreciate some help.
