AI teammates

AI Teammates adds AI-controlled teammates to Slay the Spire 2's local pseudo-multiplayer. Start an adventure with one or more AI companions. This is an experimental mod. The AI ​​functions fine, but it's not an advanced strategy robot and may make inefficient, strange, or downright wrong decisions.

✨ Module Introduction

This mod injects soul into Slay the Spire 2's local pseudo-multiplayer mode - AI teammates! 🎮Tired of climbing towers alone? Now, you can fight side by side with one or more AI-controlled partners, allowing them to act independently, choose rewards, and experience a complete tower climbing journey with you.

**PLEASE NOTE**: This is an **EXPERIMENTAL MOD**. The AI ​​is fully functional and can handle most conventional game processes, but it is not a strategy robot that pursues ultimate optimization. It may make some inefficient, weird, or even bad decisions, but that’s part of its unique charm! 🤖

🚀 Main functions

• **Smart Teammates**: Adds AI-controlled teammates to local pseudo-multiplayer games.
• **Diverse Roles**: Supports multiple teammate roles, each role has different behavior patterns.
• **Highly Configurable**: Provides independent JSON configuration files for each character for advanced players to fine-tune AI behavior.
• **Full-process support**: The AI ​​system can handle battles, rewards, potions, shops, and many events.
• **Robust operation**: On content that is not yet fully supported, conservative fallback behavior is adopted to ensure stability.

📥 How to use

• **Installation Preparation**: Install this module and its necessary dependencies.
• **File placement**: Copy the module's `.dll`, `.json` and `config` files to the `xxx\Steam\steamapps\common\Slay the Spire 2\mods\sts2AITeammate\` directory.
• **Save Migration (Optional)**: If you want to use an existing non-modded save, copy your `profile1`, `profile2` or `profile3` folder to `C:\Users\[your username]\AppData\Roaming\SlayTheSpire2\steam\[your SteamID]\modded`. If the `modded` folder does not exist, create it first.
• **Start the game**: When you start the game for the first time, the game will prompt you to load the module.
• **Enable Mods**: Launch the game again and make sure the mods are enabled.
• **Set Teammates**: Enter the AI ​​teammate setting process from the module menu item.
• **Choose Characters**: Choose your favorite characters for you (host) and AI teammates.
• **Start the Adventure**: Everything is ready, start your multiplayer tower climbing journey!

During the game, AI teammates will act autonomously when it is their turn to act, or when they are required to make battle, reward, store, potion, or event decisions.

🤖 Expectations for AI

• **Positioning**: This is a **working experimental teammate**, not an optimized competitive robot.
• **Abilities**: Ability to complete battles, claim rewards, use potions, shop and make many event choices.
• **Personality**: Different characters may exhibit different behaviors because the mod provides independent behavior configurations for each character.
• **Stability first**: Some content is processed with stability as the priority rather than pursuing "smart" decisions.

⚠️ Current Limitations

• **Limited Decision Quality**: AI may still call the wrong turn, choose awkward rewards, or make strange event and functionality choices.
• **Generic fallback behavior**: Some events still rely on generic fallback behavior, rather than intelligence specific to that event.
• **Specific Event Exclusion**: For release security reasons, the high-risk event `CrystalSphere` has been excluded from the AI ​​teammates' event pool.
• **Potential Edge Cases**: In less common multi-player related flows, edge cases and bugs may still exist.
