Magnitude halts GS

madpoet

I constrained a variable to the magnitude of (xa-xb,ya-yb)
when I set a rule based on that variable, GS freezes.

The variable is a real variable. Any suggestions greatly appreciated.

Try adding in abs() to the expression - as magnitude needs to return a positive number.

So:

magnitude(abs(xa-xb),abs(ya-yb))
