"blank" != "blank" ???

by Jeremy Tilton · in Torque Game Builder · 03/12/2005 (11:46 am) · 5 replies

Check it, the following two lines of code immediately follow eachother in script:

$piece.tag="blank";
if($piece.tag == "blank")
{

}


Yet the stuff following the if statment never exectues. Conversely:

echo($piece.tag);
if($piece.tag != "blank")
{

}

also never executes when the tag actually doesn't = "blank". Looking at the console.log it says:

T2D/client/client.cs (195): string always evaluates to 0.

Why is that?

When you are comparing strings, you need to use $=, not ==. To check for not equal, use !($piece.tag $= "blank") (I think, it's been a bit on that particular check).

Ohhhh right...kinda like how C++ actually performs == on strings....it is only equal if the same spot in memory. Cool, thanks!

Just as a follow up, if you are using a string for a switch statement, you actually need to use switch$ there as well.

Cool, i probably would have not caught that either, thanks again!

The non-equality test is $piece.tag !$= "blank".

Personally, I wouldn't have used the $ in that context since it has a significant meaning with global variables, but we have what we have :-)

Has anyone taken a stab at overloading operators in torquescript? It would be nice to support alternate syntaxes like eq and neq for strings, or === for pointer equality. Unless, of course, they are already in there and I just haven't got to them yet :-)
