Member Function Documentation

BeginPlay()

virtual void AMortarProAIController::BeginPlay ( )

overrideprivatevirtual

Event Called in beg

DrawTextAtDetectedTargets()

void AMortarProAIController::DrawTextAtDetectedTargets ( TArray< AActor * > &  TargetActors )

private

Draws Debug Text At Detected Targets.

Parameters

[in]

TargetActors

TArray containing actors sorted according to priority

FilterTargetActors()

void AMortarProAIController::FilterTargetActors ( TArray< AActor * > &  OutFilteredActors )

private

This will filter and select those actors only which are target of current actors If we select friends as target then this function will return only friends target If we select enemy target then this will return enemy target only

Parameters

[out]

OutFilteredActors

Tarray of Actors which are filtered means actors that needs to be targetd. We initially pass detected actors

GetBestTarget()

void AMortarProAIController::GetBestTarget ( TArray< AActor * > &  OutDetectedActors )

protected

This Returns Array which is sorted according to some condition could be distance etc This Function is Blueprint Native Event Allowing User to override the functionality in Blueprints

Parameters

[out]

OutDetectedActors

Tarray of Actors Detected by AI. This will sort The detected actors

GetBestTarget_Implementation()

virtual void AMortarProAIController::GetBestTarget_Implementation ( TArray< AActor * > &  OutDetectedActors )

protectedvirtual

GetEnemyKey()

FName AMortarProAIController::GetEnemyKey

(

)

const

Getter Function To get the name of key that will be used in Blackboard

Returns

Name of Key as FName

GetShouldTargetEnemies()

bool AMortarProAIController::GetShouldTargetEnemies

(

)

const

Getter Function To get whether to select enemy as target in behavior tree or not

Returns

Boolean flag denoting whether to select enemy or not

GetShouldTargetFriends()

bool AMortarProAIController::GetShouldTargetFriends

(

)

const

Getter Function To get whether to select Friends as target in behavior tree or not

Returns

Boolean flag denoting whether to select friends or not

GetShouldTargetNeutrals()

bool AMortarProAIController::GetShouldTargetNeutrals

(

)

const

Getter Function To get whether to select Neutrals as target in behavior tree or not

Returns

Boolean flag denoting whether to select Neutrals or not

GetTeamAttitudeTowards()

ETeamAttitude::Type AMortarProAIController::GetTeamAttitudeTowards ( const AActor &  Other ) const

override

Returns Behavior our AI Pawn towards a detected pawn

Parameters

[in]

Other

Actor for which we want to evaluate attitude towards

Returns

Attitude of Current owner towards Other

IsValidTarget()

bool AMortarProAIController::IsValidTarget

(

const AActor *

Target

)

Returns whether actor passed is target or not.Target depends on flags bShouldTarget Enemies/NEutrals/Friends. If we select target friends then in the case friends will be enemies :(

Parameters

[in]

Target

Actor for which we will check whether it is valid or not

Returns

True if target found False otherwise

OnDeathDelegate()

void AMortarProAIController::OnDeathDelegate ( )

private

Event Called On Death. Here we generally like to disconnect Controller which then can be deleted

OnPauseDelegate()

void AMortarProAIController::OnPauseDelegate ( )

private

Event Called When AI Dies and in future would want to resume

OnResumeDelegate()

void AMortarProAIController::OnResumeDelegate ( )

private

Event Called When AI Respawns after Death

OnTeamChanged()

void AMortarProAIController::OnTeamChanged ( FMortarProTeamProperties  PreviousTeam, FMortarProTeamProperties  CurrentTeam  )

private

Callback Function When Team is changed

Parameters

[in]	PreviousTeam	Details of Previous Team
[in]	CurrentTeam	Details of Current Team

SenseAllActors()

virtual void AMortarProAIController::SenseAllActors ( const TArray< AActor * > &  ActorsDetected )

privatevirtual

Function to be called on Perception Updation

Parameters

[in]
