Regarding your burning man example, the BurnPassive ability sets gameplay tag “Status.Burning” which is done to the gameplaytag container on the ability component(?).
On the targetmannequiun, off the “Event AnyDamage” event, in the Check Burning method, the CharacterTags variable is checked for the above gameplay tag.
I don’t see where CharacterTags gets the “Status.Burning” tag.
I am assuming the abilitycomponent’s gameplay tag variable should be used to look for the Status.Burning? (GetGameplayTagContainer)
