_Implemetation on function definition causing Linker error

Development Programming & Scripting

All my replicated functions need to have _Implementation on their .cpp definitions so they dont cause LNK 2005 error but when i do that a green line under HandleFire() apears saying no definition found and i am stuck because I need to put _Implementation to stop linker error2005 but when I fix it it creates more they are

UFUNCTION(BlueprintCallable, Category = "Gameplay")
void StartFire();

UFUNCTION(BlueprintCallable, Category = "Gameplay")
void StopFire();

UFUNCTION(Server, Reliable)
void HandleFire();

character.cpp

 void AMyCharacter::StartFire()
 {
      // call handle fire function
 }

 void AMyCharacter::StopFire()
 {
      // stop fire bool
 }

 void AMyCharacter::HandleFire_Implementation()
 {
      // firing parameters taking in bool of stop fire
 }

does anyone know how or why I am getting these errors

For using _Implementation on your function you should use corresponding macro for your UFUNCTION. In your case it is:

UFUNCTION(BlueprintCallable, BlueprintImplementableEvent, Category = “Default”)

or maybe you should check BlueprintNativeEvent.
