Wheat Farmer (intermediate)

This will show you code for a wheat farmer, meaning that it finds the closest fully grown wheat blocks, moves to them, breaks them, and finally replants them.

FarmTask.cs

Task responsible for finding, breaking, and replanting wheat.

StoreTask.cs

Task responsible for storing items into the nearest non-full chest when the bot's inventory is full.
