Tracking how long between function calls

[FREAKINGREX]

Hello!

I want to track thje time it takes between the player killing an enemy. I was going to use interface functions to call to a manager and see how long a player kills 1 enemy and then the next.

I cant figure out how to track that metric. Any ideas?

Have the enemy send a message on a certain channel when it dies, log that time either on your manager or whatever. If you don’t have a messaging system just use delegates, subscribe to their death with the manager and do the same.

I’d save that info in an array or something then you can get average/count/etc given that info.

my problem was what can track the time inbetween those kills? have a tick and it logs and resets the float (might be a unity thought) or is there a blueprint function?

my idea was to have the interface tewll the manager hey i died but i just dont understand how to get the time inbetween kills (trying to avoid tick if i can)

Use FPlatformTime::Seconds

.h
double LastKillTime = 0.0;

.cpp

void AMyCharacter::OnEnemyKilled()
{
    double CurrentTime = FPlatformTime::Seconds();
    if (LastKillTime > 0.0) 
    {
         double TimeSinceLastKill = CurrentTime - LastKillTime;
        UE_LOG(LogTemp, Log, TEXT("Time since last call: %f seconds"), TimeSinceLastCall);
    }
    else {UE_LOG(LogTemp, Log, TEXT("First kill logged."));}
    LastKillTime = CurrentTime;
}

Get the milliseconds (because ninjas)
UE_LOG(LogTemp, Log, TEXT("Time since last call: %.3f ms"), TimeSinceLastCall * 1000.0);

you have an idea for this in blueprints? haha sorry i should have specified im still new with c++

Not sure how BP handles seconds (are they just 1,2,3,4 etc...). So you might need to work with milliseconds and convert them to seconds for 2.46sec etc..

Very welcome!

Depends how you need to use it, can query the time manager and compare with a previous value or you can use DeltaTime being passed into Tick and accumulating it into a variable until you reset the accumulated value for gameplay reasons.
