When using Unreals GameplayAbilitySystem, a GameplayAbility can be triggered using a GameplayEvent.
When using UAbilityTask_WaitGameplayEvent, the GameplayEvent provides a payload of class FGameplayEventData.
Is it possible to retrieve such an event payload also from within a GameplayAbility, after it is activated by a trigger of type GameplayEvent?
A solution either in Blueprint or C++ would be fine.
It's been a long time but I think I should add an answer in case someone else comes here. After doing what you did in your pictures, you can go to your ability and delete the default 'Event ActivateAbility' and instead over-ride 'Event ActivateAbilityWithEvent'. Important to delete the default, you have to do it otherwise it will default to using it and won't trigger.
Once done, sending your trigger tag will start the ability and call this new event which will have your payload and anything else you want to send. Hope that helps!
