AI Behavior with State Machines

Implement FSM-based enemy AI logic entirely in Lua scripts.

What Is a Finite State Machine?

A Finite State Machine (FSM) defines behavior as a set of states with transitions between them triggered by conditions or events.

Represent an FSM as a table with a current state, a states table, and optional enter/exit/update callbacks per state.

local function newFSM(initialState)
  return {
    current = initialState,
    states  = {},
  }
end
