Question about Ticking

Development Programming & Scripting
1

I’ve read on many sites about Ticking or Tick in UE4. ¿What exactly does this function means?

Sorry for being a noob, but from my understanding, this funcion is called every single frame the engine renders right? If so, How do I use it or call it. I already have this code on my GameCharacter, what im trying to do is to track the Z Velocity to apply fall damage, this is what I have.

.h

		virtual void Tick(float DeltaTime) override;

.cpp

#pragma region Tick 
void ALevelsGameCharacter::Tick(float deltaTime)
{
	Super::Tick(deltaTime);
	if (GetCharacterMovement()->Velocity.Z > -200.0f)
	{
		GEngine->AddOnScreenDebugMessage(-1, 15.0f, FColor::Red, "Fatal fall");
	}

}
#pragma endregion

If you’re asking what the hell does pragma regions means, is just regions. I use them to organize and dont mess up my code. I know that there’s no code to apply damage, this is just a debugging code, to see if the engine its tracking the Z-Velocity.

Hi George,

Tick it is Actor function that calls from main actor tick and dedicated to implement custom code. You should not call this function. You should enable ticking, for that add this code:

PrimaryActorTick.bCanEverTick = true;

Hope it helps!

Yes that worked! Thanks.
