So it looked like task #1 was to make a gameplay task that played a flipbook instead of an anim montage.
To do that properly, I needed to add my own data to the ActorInfo variable that’s passed around throughout the ability system.
So let’s chase down some code!
First spots to look are here:
and here:
So this says can be configured per project, and that you can override UAbilitySystemGlobals::AllocAbilityActorInfo. What it means is you can add an entry like this to your defaultgame.ini
This tells the ability system globals to use the class here for its globals instance – which you can subclass like so:
This lets you define your own AllocAbilityActorInfo() which you can stuff a custom FGameplayAbilityActorInfo into like so:
And now in your new subclass of FGameplayAbilityActorInfo you can override InitFromActor() to init your new variable:
