AShooterCharacter::TakeDamage doesn`t work

[Ivan_Bakaev]

Hello, people!

In the SimpleShooter game my function(TakeDamage) doesn`t do any damege/reaction.
A tried:

• to debug using UE_LOG, but no UE_LOG outputs;
• recompile BP_ShooterCharacter;
• replace enemy;
• rebuild level;
• restart Unreal Engine (4.26).

But still no reaactions. Please help )

Where are you calling TakeDamage?

That’s a great question. I questioned it myself, but have no idea) The main idea was to override this function from Gun.h. But still it doesn’t have it inside. We have a PullTrigger() func in Gun.cpp and inside PullTrigger() we call a TakeDamage().

Could you show the code for that?

Thanks for attention for my question, I have made a logical error: I`ve added “!” mark in statement where I should call the function

I have another question: I have 2 statements

“if (HitActor != nullptr)”

and " if (HitActor) " aren`t those the same?

Any difference between if (HitActor) and if (HitActor != nullptr)?

Pointers are convertible to bool. From the C++ standard: A prvalue of arithmetic, unscoped enumeration, pointer, or pointer-to-member type can be converted to a prvalue of type bool. A zero value, null pointer value, or null member pointer value is converted to false; any other value is converted to true. Personally I find if (Pointer) and if (!Pointer) far more readable as if (Pointer != nullptr) is a double negative (!= + nullptr) which I find harder to parse and often have to double ta…
