T2 farm (tokentoken)

Contracts:
Seed -> ERC20 tokens with 0 decimals.
Product -> ERC20 token with 0 decimals.
Dish -> ERC721 token.
Plot -> ERC721 token with 0 decimals and a limited cap (currently expected at 1000000).
Farm -> Main interaction contract. Player wallets can perform these actions:

• buyPlot -> deposit Farm accepted tokens and receive a Plot.
• buySeeds -> deposit Farm accepted tokens and receive a Seed/Seeds.
• plant -> deposits seeds + plot -> creates a plant.
• harvest -> harvests existing plant - wallet receives back the plot and products (quantity determined by seed yield param).
• convertProductsToSeeds -> deposit products receive same quantity of seeds.
• convertProductsToDish -> deposit required quantity of products receive one Dish token.

[Temp] Stable Token -> Freely mint Farm accepted ERC20 tokens.
Farm settings -> contains seed-product mapping and plot contract reference.

Future plans

• Consider moving farm shop to uniswap (buy seeds in uniswap).
• Adding an increasing cost to crafting Dishes so their value would naturally increase over time.

Farm setting requirements

• SEASON_DURATION - single season duration in blocks (total 4 seasons Winter, Spring, Summer and Autumn).
• PLOT_WATER_REGEN_RATE - plot water gain per block.
• PLANT_WATER_ABSORB_RATE - plant water absorb rate from plot it's planted on.
• PLANT_NEIGHBOR_WATER_ABSORB_RATE - plant water absorb rate from direct neighbor plot.
• PLOT_MAX_WATER - plot max possible amount of water accumulation.
• PLOT_AREA_MAX_X - total game area X length in plots.
• PLOT_AREA_MAX_Y - total game area Y length in plots.

Contracts

Each item has its own contract (Products/Seeds/Dishes/Plot). Contract used to manage them and contain the state of plants is the Farm.

At the moment of writing hardhat supports up to 0.8.22 (currently 0.8.22v used in code)

Water

• For simpler math plants are always absorbing water as long as they are planted (to avoid the need to recalculated the entire map each time)
• Plots water level is not in sync in contract, one will only be updated once some action was taken that involves it (plant/harvest)

NOTES:

• Currently the game deployed only on Polygon Amoy testnet.
• Weed is a special plant whose product can only be obtained by overgrowing any other plant.
• Crafting dishes requires correct product array order (bug -> feature, allows for more recipes)
