State Machine

State Machine Mod

With this mod you can build a deterministic finite-state machine in Minecraft.

The set of items (NOT ITEM STACKS) in your game is your alphabet. States are placed blocks. If a state is the current one of some state machine it will emit redstone signal.

Operations

• Create Transition: Hold an item in the offhand and any wrench (state machine tool) in the main hand, then right‑click two state blocks. The first clicked block is the source state, the second is the target state.
• Create Default Transition: Same as creating a transition, but with an empty offhand.
• Remove Transition: Hold an item in the offhand and use any wrench (state machine tool) to right‑click a state block whose transition you want to remove. If the offhand is empty, the default transition is removed.
• Set State Machine Block State: Right‑click a state machine block with any wrench (state machine tool), then right‑click the target state.
