UAbilitySystemComponent::ServerSetReplicatedTargetDataCancelled

#include "AbilitySystemComponent.h"

Access: public Specifiers: UFUNCTIONServerreliableWithValidation

Description

Reliable server RPC that notifies the server the player cancelled targeting. Fires the target data cancelled delegate and allows the server to end the targeting phase.

Caveats & Gotchas

• No target data payload is sent — cancel carries only prediction keys to identify the correct ability activation to clean up.
• If server-side logic already applied predicted effects based on anticipated target data, those effects must be rolled back separately; this RPC only signals the cancel, it does not undo anything.
