Is there a way to use multi-line expressions?

[magneto]

One of the expression I need to use requires multiple lines, but since it's very specific, I don't want to create an expression function for it.

Can I use multi-line statements using the expression editor? I tried this but didn't work:

float CalculateSize ()
{
    return 1;
}

CalculateSize();

It's hscript.

Thanks.

Did you try to press Alt + E to edit the field contents?

Yes that's what I did, but after clicking Apply or Accept, turns the node into error state saying "unable to evaluate expression, syntax error"

The expression editor does allow you to using multiple lines. It will save the expression with a \n as the newline character, but it still has to all be part of a single line expression.

As a work around, break your expression down into multiple parts and create a few custom parameters. Each custom parameter can eval part of the expression. I sometimes do this, and it makes it easier to read/debug.

Thanks, that would work too. But I still need to use an if conditional to chose which value to use. Do you know the if syntax for single line expressions?

Because using this didn't work either:

if ($TX < 1) 0.5 else 1

I found it thanks to Symek who shows it here:

{
float dist = distance(0,0,0, $TX, $TY, $TZ);
float div = dist / 5;
return div;
}

If your using hscript then you use the if() statement, which is a function that takes three arguments.

There is also the ifs() for strings.

Thanks man, I didn't know they had that function either. It's all very useful.
