Undefined function parameters return 0 instead of "" as in construct 2

I was writing an entire project using this "feature" until it was changed from construct 2 to construct 3.

This allowed me to make a get/set in the same function with the convenience of checking if additional parameters were empty or not. The issue with return 0 instead of "", is that I would never send a blank string as a variable to function -- but I WOULD pass zero as a parameter.

Now I would not be able to say if param(x) == "", set variable to param(x).

I have had to rewrite a thousand lines of code to redo all get/sets functions and calls. Which has been extremely frustrating, as well as making no sense.

Why was this changed? How is this a benefit over how it was in C2?

I guess the alternative could be:

if param(x) == 0 && param(x+1) == "Set" >> set varaible to 0. But this sucks. It was better before. At least from my perspective.

Why did this change?

Because "" could cause an error, and zero wont.

if param(x) == 0 && param(x+1) == "Set" >> set varaible to 0.

Are you still using the old Function object? You really should update it to built-in functions. You will be able to name and set a proper type for each parameter.
