Hello! Im looking for a way to get GameplayTag from Hit Actor in line trace. With actor tags its very simple, similar methods with GameplayTags dont seem to work and there is very limited information online. Is there a way to do this? Thanks!

Your class needs to implement the IGameplayTagAssetInterface and store a FGameplayTagContainer. I think this can only be done in C++ (unless it has changed recently). This article has helpful info for getting started.
