Can you call a function depending on which number an integer is

Development Programming & Scripting

you may get the function at generated files, and call it via

FString FuncName = “Function1”;
UFunction* const Func = UObjectPtr → FindFunction(FuncName);
if(Func)
Func ->ProcessEvent(Func);

if your function has some params, you’ll need to create a struct suit the params, and get values of params, then instead of ProcessEvent(Func), ProcessEvent(Func, &Params);

I want to have

Function1

Function2

And call them depending on a variable

Maybe if the functions are in some sort of array

What is the best way to do this

So to change the function it calls I change the FuncName string

Eg

 void ChangeStringFunc()
 {
      if (SOMETHING)
      {
           FString FuncName = "Function1"; 
      }
      else
      {
            FString FuncName = "Function2";
      }
 }

 void CharacterFunction()
 {
 UFunction* const Func = UObjectPtr -> FindFunction(FuncName);
 if(Func) Func ->ProcessEvent(Func);
 }

Hi,

This seems like a good use of a switch statement, look at the example below:

switch(myInteger) {
  case 1:
    Function1();
    break;
  case 2:
    Function2();
    break;
  default:
    // If no case exists for myInteger
    GEngine->AddOnScreenDebugMessage(-1,1.f, FColor::Blue, "switch failure");
}

Switch statements are more performant and preferred over an if/else statement, each case can include any amount of code you would like.

Kind Regards,
