About this project
What does Radical Cobblemon Trainers API add?
Radical Cobblemon Trainers - API
Trainer management and battle API for Cobblemon.
This API was developed as foundation for the Radical Cobblemon Trainers mod and as replacement for the discontinued dependency CobblemonTrainers for Minecraft >= 1.21 and Cobblemon >= 1.6.
Yet it is designed as independent library to provide a subset of similar features for everyone to use.
Key features
- Trainer management and entity association (trainer registry)
- Support for different battle formats (1v1 SINGLE, 1v1 DOUBLE, 2v2 MULTI, ...)
- Custom battle rules (e.g. max item usages per battle)
- Extended AI features (currently only supported by
RCTBattleAI):- Usual battle activities (move selection, switch, ...)
- Gimmicks: Mega evolve, Dynamax, Z-Moves, Terastallize, etc. (most gimmicks that are activated by held items will require another mod to provide them. Mega Showdown would be an example and is also required for dyna- and gmax)
- Trainers can carry and use items
- Trainer and pokemon models (pojos) for easy parsing
- Converters to Cobblemon types
- Model validation (collects all errors before an exception is thrown)
