new to c++ and cant set each actor with a health component i made to have a different health value

[Roy_Wierer.Seda145]

i know that the health component is set to “visibleAnywhere” instead of “EditAnywhere”

Components added in c++ and stored under a UPROPERTY should always be marked VisibleAnywhere instead of EditAnywhere. EditAnywhere leads to blueprint corruption when dealing with components. At that point only recreating of a blueprint asset gets rid of odd problems.

@annonymousfart1

UPROPERTY(BlueprintAssignable)
FHealthComponentDeadSignature OnHealthComponentDead;

UPROPERTY(BlueprintAssignable)
FHealthComponentDamagedSignature OnHealthComponentDamaged;

UPROPERTY(BlueprintAssignable)
FPlayerRespawnedSignature OnPlayerRespawned;

UPROPERTY(BlueprintReadOnly, visibleAnywhere)
bool CanTakeDamage;

UPROPERTY(VisibleAnywhere, BlueprintReadWrite);
float _MaxHealth;

All your properties are missing property initialisation in the example code you show. This leads to undefined behavior.

@annonymousfart1

OwningCharacter->TakeDamageEvent_Implementation(Causer);

You are calling the “_Implementation” version of a function when you should be calling the non implementation version “TakeDamageEvent”.

@annonymousfart1

OwningCharacter->OnTakeAnyDamage.AddDynamic(this, &UHealthComponent::DamageTaken);

@annonymousfart1

void UHealthComponent::DamageTaken(AActor* DamagedActor, float Damage, const UDamageType* DamageType,
AController* Instigator, AActor* Causer)

@annonymousfart1

OwningCharacter->TakeDamageEvent_Implementation(Causer);

You are looping. If owning character takes damage then call health component DamageTaken, then call OwningCharacter->TakeDamageEvent. It’s a loop?

I hope that the issue is solved once you fix the errors I see right now. Else, let me know and we can look at the updated code.

I’ve made a plugin a while back which can be used as a health component (or stamina, or literally anything else) which I placed online for sale. You can also get that for a working system and a good code example:
