Creating a finite state machine agent
Now that we've created a finite state machine, we can simply replace the decision tree that
powers our indirect soldier agent with a finite state machine. The initialization, updating,
and termination of our FSM are identical to the decision tree.
With an abstract data structure, we can now create both decision-tree-based agents and fi-
nite state machine agents simultaneously:
IndirectSoldierAgent.lua
:
local soldier;
local soldierController;
local soldierFSM;
local soldierUserData;
function Agent_Initialize(agent)
...
soldierFSM = SoldierLogic_FiniteStateMachine(
soldierUserData);
end
function Agent_Update(agent, deltaTimeInMillis)
if (soldierUserData.alive) then
soldierFSM:Update(deltaTimeInMillis);
end
soldierController:Update(agent, deltaTimeInMillis);
end
