To build a finite state machine for our agent, we'll create the initial states that wrap each possible action. As the state machine needs a starting point, we'll set the state explicitly to the idle state to begin with. Once the idle state has finished, our state machine will automatically pick the most relevant action to execute afterward:
SoldierLogic.lua:
function SoldierLogic_FiniteStateMachine(userData)
local fsm = FiniteStateMachine.new(userData);
fsm:AddState("die", DieAction(userData));
fsm:AddState("flee", FleeAction(userData));
fsm:AddState("idle", IdleAction(userData));
fsm:AddState("move", MoveAction(userData));
fsm:AddState("pursue", PursueAction(userData));
fsm:AddState("randomMove", RandomMoveAction(userData));
fsm:AddState("reload", ReloadAction(userData));
fsm:SetState("idle");
return fsm;
end
