BindAction delegate with parameters

[anonymous_user_7650ef01]

Hi Lordmatics,

I had the same problem and that’s what i did to resolve it:

.h

    void AbilityTestInUse(int32 index);

     template<int32 Index>
     void AbilityTestInUse() 
{
         AbilityTestInUse(Index);
     }

.cpp

         InputComponent->BindAction("Ability1", IE_Pressed, MyCharacter, &AConceptCharacter::AbilityTestInUse<1>);
         InputComponent->BindAction("Ability2", IE_Pressed, MyCharacter, &AConceptCharacter::AbilityTestInUse<2>);
         InputComponent->BindAction("Ability3", IE_Pressed, MyCharacter, &AConceptCharacter::AbilityTestInUse<3>);
         InputComponent->BindAction("Ability4", IE_Pressed, MyCharacter, &AConceptCharacter::AbilityTestInUse<4>);
         InputComponent->BindAction("Ability5", IE_Pressed, MyCharacter, &AConceptCharacter::AbilityTestInUse<5>);

 void AConceptCharacter::AbilityTestInUse(int32 index) {
     // do stuff
 }

It’s because templates are always declared in header (if not, you cannot compile)
