UAbilitySystemComponent::AbilityTargetDataCancelledDelegate
#include "AbilitySystemComponent.h"
Access: public
Description
Returns a reference to the multicast delegate that fires when the client replicates a targeting cancellation for the given ability/prediction-key pair. Bind to this on the server to react when the player cancels a targeting phase.
Caveats & Gotchas
- • The returned delegate reference is keyed to the specific ability/prediction-key pair; binding to it with a stale prediction key will never fire.
- • Delegates in AbilityTargetDataMap are not automatically cleaned up — call ConsumeAllReplicatedData after processing to avoid memory growth across many ability activations.
