Ahh yes, it was the extra assignment causing the increase in size.

However, your first version trumped the ternary by quite some margin – saving an extra 6 bytes in total

Sorry – last comment I promise! Should be * 400 in the second line of the example above, not * 550…

btw, your ternary examples should probably be:

x = (lx == 0) ? Math.random() * 550 : lx;
y = (ly == 0) ? Math.random() * 550 : ly;

The extra assignments might explain the extra bytes…

Cheers,

How about this?

x = lx || Math.random() * 550;
y = ly || Math.random() * 400;

I’d be interested to know if it came out smaller or not… It certainly looks smaller…

Cheers,
