Class Architecture

38 /57

Main Class

• Body– Bridge between client itself and Unreal Tournament 2004– Method for agent control

• Memory– Contain History, which is the storage of all sensory data

coming from Body– Implement interface WorldView, RecentMemory, Knowl-

edge and Invertory• Inventory

– Basically an array of weapon• Game map

– Module for navigation– Built-in A* algorithm– Provide method for obtaining path to desired location

39 /57

Body

• MoveTo(Location) – simple RUNTO command, input anything that implements

ILocated or is location. • Stop() <SC>

– stops the bot immediately • TurnHorizontal(amount)

– roll is not used for bots. • TurnVertical(amount) • TurnTo(Location)

– target can be again object or location... • Jump() <SC> • Run() –

– disables walking • Walk()

– enables walking

40 /57

Navigation

• safeRunToLocation() • GetPath(Target) - target can be location or Ilocated. • RunAlongPath(Id of path) • RunAlongList(list of Ilocated objects)

– will request paths and do everything automaticaly • ReachCheck(Target) - anything Ilocated. • GetPath() • RunAlongListOfILocated(List) • nearestWeapon(type) • nearestXY()

41 /57

• Shoot() • StopShoot() • ChangeWeapon() • StopShoot()<SC>

– stops shooting• Shoot(Target, Mode, Time)

– how long we should be shooting • ShootCharged(Target,Mode)

– for charging weapons• ChangeWeapon(Weapon)<SC>

– Weapon in inventory with correct inventoryId • ChangeWeaponToBest()<SC>

– issues UnrealScript command

42 /57

Memory

• WorldView– Information about what agent currently sees– Internal status

• Current health, weapon, ammo, visible navigation point, enemies

• RecentMemory– A bit older information

• Knowledge– Persistent knowledge about the map
