Undo and redo

Provides combat undo/redo functionality for Slay the Spire 2.

UndoAndRedo

🎮 **A combat rollback tool specially designed for "Slay the Spire 2"! ** Tired of playing the wrong cards with a slippery hand? This mod allows you to easily undo actions, like having a "regret potion" in the game.

✨ Core Functions

• **Undo/Redo multiple operations**: Supports undoing or redoing cards, ending the turn, using potions, and discarding potions.
• **Complete combat status snapshot**: When recovering, all your health, block, ability, energy, hand cards, random number seeds, monster actions, relics, potions, charge balls, etc. will be perfectly restored.
• **Visual synchronized refresh**: Hand cards, ability icons, potion slots, deck counts, monster intentions, and card descriptions will all be updated correctly to ensure that the interface is consistent with the game state.
• **Safe and Reliable**: Only activates during your turn and the action queue is idle, avoiding the risk of status damage.

🎯 How to use

The operation is extremely simple!

• **Undo**: Press the **Left Arrow Key** of the keyboard.
• **Redo**: Press the **right arrow key** of your keyboard.

⚙️ How it works

Before the player performs each action (playing a card, ending a turn, using/discarding a potion), the module takes a "snapshot" of the entire combat state. When you select Undo, the game loads directly from the previous snapshot rather than re-simulating the process, refreshing all visual elements to match the restored state.

⚠️ Known limitations

• **Single player mode only**.
• **Cannot be undone during the enemy's turn or animation**.
• **Undo by action**: The smallest unit of undo is a complete player action, not the selection process of a single card.

💡 **Usage Suggestions**: This module is an excellent tool for practicing complex combos and testing different playing strategies. It can also save your gaming experience when you are annoyed by misoperations!
