UAbilitySystemComponent::CallReplicatedTargetDataDelegatesIfSet

#include "AbilitySystemComponent.h"

Access: public

Description

Fires the TargetData Confirm and Cancel delegates if target data has already been replicated for the given ability and prediction key pair. Returns true if the delegates were called.

Caveats & Gotchas

• Only fires if target data was already received — if the server calls this before the client sends data, the delegates will not fire and you must bind to them manually via AbilityTargetDataSetDelegate.
• Unlike CallAllReplicatedDelegatesIfSet, this only fires TargetData callbacks, not Generic Replicated Events — be careful not to mix the two patterns in the same ability.

Example

    ASC->AbilityTargetDataSetDelegate(AbilityHandle, OriginalPredKey)
        .AddUObject(this, &UMyTargetDataTask::OnTargetDataReceived);
