Remarks

Class used to perform custom gameplay effect modifier calculations, either via blueprint or native code

Variables

		Name	Description
	bool	bAllowNonNetAuthorityDependencyRegistration	Whether the calculation allows non-net authorities to register the external dependency multi-cast delegate or not; Effectively whether clients are allowed to perform the custom calculation themselves or not

Constructors

	Name	Description
	UGameplayModMagnitudeCalculation ( const FObjectInitializer& ObjectIn... )

Functions

	Name	Description
float	CalculateBaseMagnitude ( const FGameplayEffectSpec& Spec )	Calculate the base magnitude of the gameplay effect modifier, given the specified spec.
bool	GetCapturedAttributeMagnitude ( const FGameplayEffectAttributeCaptu..., const FGameplayEffectSpec& Spec, const FAggregatorEvaluateParameters..., OUT float& Magnitude )	Convenience method to get attribute magnitude during a CalculateMagnitude call
FOnExternalG...	GetExternalModifierDependencyMulticast ( const FGameplayEffectSpec& Spec, UWorld* World )	If the magnitude resultant from the custom calculation depends on game code-specific conditions that are not under the purview of the ability system, this method should be overridden to provide a multicast delegate that will fire when the reliant conditions change, so that the magnitude can be recalculated and updated.
bool	ShouldAllowNonNetAuthorityDependencyRegistration()	Simple accessor to bAllowNonNetAuthorityDependencyRegistration with some validation: Read the comment on that variable for usage!!!
