beegone

A chess-like game themed around bees, featuring:

• A Rust backend
• A svelte frontend
• 7 types of pieces with different abilities
• Frontend move calculation by compiling the game's logic to WASM
• A computer player that plays pretty okay, using rival
• No win conditions implemented (I got distracted)

Rules

The game is played by two players, taking turns. Each player starts with a queen, a drone, and two nurses. During your turn, you can either move a piece, capture an enemy piece or use a piece's special ability.

Moving

Every piece can move to any of the six tiles adjacent to it, as long as there is no other piece or wall there. Moreover, if a piece is adjacent to a piece of the same team, it can 'hop over' that piece, as long as that tile is accessible (either empty or they can capture the piece standing there).

Capturing

Most pieces can capture an enemy piece adjacent to them by moving their piece onto the same tile. However:

• Guards can only capture other guards, gatherers, builders, nurses, workers and drones
• Gatherers can only capture other gatherers, builders, nurses, workers and drones
• Builders can only capture other builders, nurses, workers and drones
• Nurses can only capture other nurses, workers and drones
• Workers can only capture other workers and drones
• Drones can only capture other drones

Summarized, pieces can only capture the same or 'weaker' pieces, where guards > gatherers > builders > nurses > workers > drones. Additionally:

• Queens are unable to capture at all, and cannot be captured normally
• Walls can only be captured by builders

Special abilities

Some pieces have special abilities:

• Queens can spawn drones on any adjacent tile, or, if a drone is already adjacent, she can spawn workers on any adjacent tile
• Nurses can promote adjacent workers to builders, gatherers or guards
• Gatherers can walk in a straight line any number of tiles, as long as there is nothing blocking the way (they may also do this right after hopping over an ally)
• Builders can place walls on adjacent tiles

Winning the game

As I said, I never implemented a win condition, so you can continue playing for as long as you want. Originally, I intended to implement the following win conditions:

• It's your opponent's turn, but they're unable to make a move
• You capture both your opponent's nurses
• You have surrounded your opponent's queen with 3 guards

But the second didn't feel fair if you already had many promoted pieces to win the game with, and the third made the game drag on for way too long. Instead, you can pretend that guards can capture enemy queens normally, and doing so ends the game.

To further limit how long the game takes, you can pretend that a queen may only spawn up to 3 drones before getting tired, and nurses may only promote 15 pieces in total. Stalemates may happen, I didn't playtest enough.
