Weird two call method

[gc8 970]

Hi

I ran to this weird coding dilemma which I basically solved but the result was so bizarre I wanted to ask you guys if you knew a better/correct way of doing this.

 

Here's my code:

 

myTestFnABC =
{
 systemchat "Teeeest!";
};



// Construct the above function name

_test = "ABC";

 private _fnName = format["myTestFn%1", _test];


 if(!isNil _fnName) then // Does the variable exist?
 {
 // Weird two calls code
  call call compile _fnName;
 };

 

As you can see I am construction the function name string and then compiling it and calling twice to get the myTestFnABC executed. Surely there has to be other way than two calls? (Without changing the fact that I need the function name constructed like above)

 

thx  for your thoughts

I guess you could do 

private _fnName = {
	private _thingy = param [0];
	call compile format["myTestFn%1", _thingy];
};

["ABC"] call _fnName;

😂

 

But yes, it's a bit weird.

@marceldev89 I think that code wont work and myTestFnABC is not called. Hence I ended up doing two calls

You could try including the first call in the formatted string to clean it up a bit, but otherwise, due to how compile works, I don't think there's any way around it; compile returns a code object, wrapped in parentheses, so you need to run that code first to return the value of the variable.

 

Also, isNil takes a string as an argument, not a variable.

IMHO, a string like your _fncName is not a stringyfied code. If you want some result using a code, you need to use at least an operator, a command, or a function applied to variable.

call (missionNamespace getVariable [_fnName, {hint format ["Ooops, function '%1' is undefined", _fnName]}]);

Yep that's what is happening. i was also thinking the same, have the other call in string to clean it up a bit

I'm giving it a string variable, that worked for me

that a bit over my head

That works, thanks!
