Syntax

[USTRUCT](Programming/UnrealArchitecture/Reference/Structs)([BlueprintType](Programming/UnrealArchitecture/Reference/Structs/Specifiers/BlueprintType))
struct FGameplayAbilityTargetDataHandle

Remarks

Handle for Targeting Data. This servers two main purposes: -Avoid us having to copy around the full targeting data structure in Blueprints -Allows us to leverage polymorphism in the target data structure -Allows us to implement NetSerialize and replicate by value between clients/server

-Avoid using UObjects could be used to give us polymorphism and by reference passing in blueprints. -However we would still be screwed when it came to replication

-Replication by value -Pass by reference in blueprints -Polymophism in TargetData structure

Variables

		Name	Description
	TArray< TShared...	Data	Raw storage of target data, do not modify this directly
	uint8	UniqueId

Constructors

	Name	Description
	FGameplayAbilityTargetDataHandle()
	FGameplayAbilityTargetDataHandle ( FGameplayAbilityTargetData* Da... )
	FGameplayAbilityTargetDataHandle ( FGameplayAbilityTargetDataHandle&&... )
	FGameplayAbilityTargetDataHandle ( const FGameplayAbilityTargetDataHan... )

Functions

	Name	Description
void	Add ( FGameplayAbilityTargetData* Da... )	Adds a new target data to handle, it must have been created with new
void	Append ( const FGameplayAbilityTargetDataHan... )	Does a shallow copy of target data from one handle to another
void	Clear()	Resets handle to have no targets
const FGamep...	Get ( int32 Index )	Returns data at index, or nullptr if invalid
FGameplayAbi...	Get ( int32 Index )	Returns data at index, or nullptr if invalid
bool	IsValid ( int32 Index )	Returns true if there are any valid targets
bool	NetSerialize ( FArchive& Ar, UPackageMap* Map, bool& bOutSuccess )	Serialize for networking, handles polymorphism
int32	Num()	Returns number of target data, not number of actors/targets as target data may contain multiple actors

Operators

	Name	Description
bool	operator!= ( const FGameplayAbilityTargetDataHan... )	Comparison operator
FGameplayAbi...	operator= ( FGameplayAbilityTargetDataHandle&&... )
FGameplayAbi...	operator= ( const FGameplayAbilityTargetDataHan... )
bool	operator== ( const FGameplayAbilityTargetDataHan... )	Comparison operator
