Replicated event crashes on client

[GKoch (WFG)]

Hello, I’m having trouble replicating a custom event.
If I replicate the event on client, it crashes the engine. If i set the event to not be replicated, it only works on the server.

Here’s where i try to call the event:

Looks like you’re using GAS? I personally wouldn’t use RPC’s within an ability as I’m not entirely sure how exactly that would scope? If you want to trigger a UI cooldown animation you can write a function that gets the cooldown of a specified ability tag, assuming you actually commit a cooldown in the ability. I have this code in an old project that I’m pretty sure I came across somewhere online.

bool AGASCharacterBase::getCooldownRemainingForTag(const FGameplayTagContainer CooldownTags, float& TimeRemaining, float& CooldownDuration)
{
if (AbilitySystem && CooldownTags.Num() > 0) {
TimeRemaining = 0.f;
CooldownDuration = 0.f;

  FGameplayEffectQuery const Query = FGameplayEffectQuery::MakeQuery_MatchAnyOwningTags(CooldownTags);
  TArray< TPair<float, float> > DurationAndTimeRemaining = AbilitySystem->GetActiveEffectsTimeRemainingAndDuration(Query);
  if (DurationAndTimeRemaining.Num() > 0) {
  	int BestIdx = 0;
  	float LongestTime = DurationAndTimeRemaining[0].Key;
  	for (int Idx = 1; Idx < DurationAndTimeRemaining.Num(); ++Idx) {
  		if (DurationAndTimeRemaining[Idx].Key > LongestTime) {
  			LongestTime = DurationAndTimeRemaining[Idx].Key;
  			BestIdx = Idx;
  		}
  	}

  	TimeRemaining = DurationAndTimeRemaining[BestIdx].Key;
  	CooldownDuration = DurationAndTimeRemaining[BestIdx].Value;

  	return true;
  }

}
return false;
}

I’d link the source but I honestly don’t remember where I got it from.

Your target widget can just query that function with the appropriate tags you want the cooldown for and apply outputs to your (im assuming) material mask.

Hi!

I think this approach could work for my use case, but slightly modified given that i already have a function to get the CD Duration. My quiestion at this point would be where to call this from? from the gameplay ability once committed, or somewhere else?

[boyty01]

I would call it from whatever needs the information? My implementation was in an RPG setting where you had a typical action bar, each individual skill that was on my bar would query their appropriate tag. I integrated it on tick originally, but on reflection that probably wasn’t the best idea.

Brilliant! your code helped me do exactly what i wanted to do, I’ll mark it as an asnwer and attach a screenshot of how i ended up setting up the blueprint for my skill. Much as you did, I ended up placing it on the tick function, since my characters would only have two skills.
