We have the ABS living on player state.
inside InitAbilityActorInfo we call our own RemoveAllGameplayTagsAndEffects function
if ( InOwnerActor->HasAuthority() || InOwnerActor->HasLocalNetOwner() )
{
//reset any previous tags and effects, don’t do this for sim proxies to prevent JIP wiping all tags
RemoveAllGameplayTagsAndEffects();
}
my current version of this function looks like this:
void UOurAbilitySystemComponent::RemoveAllGameplayTagsAndEffects()
{
// Remove all active effects (removes effect-granted tags)
RemoveActiveEffects( FGameplayEffectQuery() );
// Remove all loose tags
FGameplayTagContainer OwnedGameplayTags = GetOwnedGameplayTags();
for ( const FGameplayTag& Tag : OwnedGameplayTags )
{
SetTagMapCount( Tag, 0 );
}
const bool HasLocalNetOwner = GetOwner()->HasLocalNetOwner();
if ( HasLocalNetOwner || GetOwner()->HasAuthority() )
{
// Clear minimal replicated owned tags
GetMinimalReplicationTags_Mutable().RemoveAllTags();
}
if ( GetOwner()->HasAuthority() )
{
// clear replicated loose tags
GetReplicatedLooseTags_Mutable().RemoveAllTags();
}
}
This attempts to nuke all gameplay tags. But in practice, once the tag map is modified again after respawn the deleted replicated loose tags will reappear on the actor for other players (locally the tags remain wiped it seems).
Are there any suggestions you can make to fix this function so it reliably wipes everything?
I am aware that the intended flow is that sources of tags all self manage, but we are working on a prototype and adding/removing loose tags is more convenient in most cases and adding them via gameplay effects etc is often overkill for many of our use cases.
Is Epic planning on adding a generic wipe all tags function of their own? If not, should we be recreating the ABS every time the player respawns instead? This would cause it’s own headaches, so is not preferable.
Is there a reason this functionality is not exposed besides enforcing design patterns for how tags should be removed added?
I also know this system is being updated in 5.7, will this problem go away / will we need a new way to solve?
Thanks
