Cobblemon Run & Bun Doubles
by Jobel
Cobblemon Run & Bun Doubles changes the Cobblemon trainers that Run Bun Advanced Trainer AI controls so they battle in doubles format.
What it does
The data pack switches Cobblemon trainers from single to doubles battles. It affects the trainers added by the Radical Cobblemon Trainers mod, which the Run Bun Advanced Trainer AI mod drives. Trainers that already use doubles, and those that fight with a single Pokemon by design, are left as they are, so only the single-battle trainers change format.
The change is limited to the trainer files. Nothing else in the trainer definitions is altered except the battle format line and the AI setting that the doubles format needs, so the rest of each trainer stays as published. The author describes the goal as sparing players the work of editing each trainer by hand. Installation needs Fabric or NeoForge for the mod version, and a data pack option is available for modpacks and servers that cannot use the mod itself. Files are for 1.21.1 only. Only the server needs to run the mod or data pack, while players may leave it out. The license is All rights reserved, so the code is not open source.
Key features
Doubles trainer battles
Single-battle trainers from the Radical Cobblemon Trainers set are switched to doubles format for the Run Bun AI.
Untouched doubles trainers
Trainers that already fight in doubles, or use one Pokemon on purpose, keep their original setup.
Data pack option
The same change ships as a data pack, for modpacks and servers where the mod version does not load.
Manual edits avoided

What the author says
Changes every trainer except for the ones that are already on doubles or that have only 1 pokemon to doubles format as well as applying the Run and Bun AI. Nothing is changed except for adding a line that adds doubles as well as a line that changes the AI. outside of that the files are identical to the rctmods…
