Package-level declarations

Types

class AStarGoapPlanner(val worldStateDeterminer: WorldStateDeterminer) : OptimizingGoapPlanner

Implements a Goal-Oriented Action Planning system using the A* algorithm. A* works by finding the optimal sequence of actions to transform an initial state into a goal state while minimizing total cost. See https://en.wikipedia.org/wiki/A*_search_algorithm

ConditionDetermination

enum ConditionDetermination : Enum<ConditionDetermination>

Conditions may be true, false or unknown

EffectSpec

typealias EffectSpec = Map<String, ConditionDetermination>

GoapAction

interface GoapAction : GoapStep, Action

Action in a GOAP system.

GoapGoal

interface GoapGoal : GoapStep, Goal

Goal in a GOAP system.

GoapPlan

class GoapPlan(val actions: List<Action>, val goal: Goal, val worldState: GoapWorldState) : Plan

GoapPlanner

interface GoapPlanner : Planner<GoapPlanningSystem, GoapWorldState, GoapPlan>

GoapPlanningSystem

data class GoapPlanningSystem(val actions: Set<GoapAction>, val goals: Set<GoapGoal>) : PlanningSystem

GoapState

typealias GoapState = Map<String, ConditionDetermination>

GoapStep

interface GoapStep : Step

GoapWorldState

data class GoapWorldState(val state: GoapState = emptyMap()) : WorldState

Represents the state of the world at any time. World state is just a map. This class exposes operations on the state.

OptimizingGoapPlanner

abstract class OptimizingGoapPlanner(val worldStateDeterminer: WorldStateDeterminer) : GoapPlanner

Abstract class for a Goap planner with common optimization.

WorldStateDeterminer

interface WorldStateDeterminer

Determine the world state: the conditions that drive GOAP planning Our conditions can have 3 values: true, false or unknown. Unknown may be genuinely unknown, or it may mean that the condition has been lazily evaluated and needs to be evaluated again.
