Go to books page and search for genetis sorting machine level. Everything is explained there. But basically how it works is that Ugly acts as a baloon in forcefields tagged antigrav=true. There are two forcefields and both are pushing things to the right. But because ugly is antigrav, he will go to the left. That's the trick.

Does that mean that antigrav=true in the ugly makes it act like a balloon in antigrav=true force fields?

Yes. That's also why you can never have Uglies and Balloons in the same place. Each level (except GSM) in chapter 2 has one type or the other, depending on the mechanics: Volcanic Spa has an Ugly, since UglyProducts don't burn/poison, for example.

Wait a second....What if i attach an ugly in the editor? will it fly up?

Why ask? Try it.
In the case of Uglies, attaching/unattaching makes no difference, as they have isantigravunattached=true, which means they float up no matter what. Balloons, on the other hand, have isantigravunattached=false, which means they fall down when not attached. But keep in mind that only forcefields with antigrav=true will cause either to float upwards. If you have a forcefield with antigrav=false, balloons won't float up, and neither will uglies. WooGLE defaults forcefields to antigrav=true.

(I'm going off memory here; someone correct me if I'm wrong in any of this)

I had an ugly in my level once...Did not float up, even though i did not change the forcefield...

EDIT Oh, wait that was a beauty.... Anyways NOOOW I GET IT! THAT IS WHY THERE ARE NO BALLOON GOO WHEN THERE IS AN UGLY! SO THE ANTIGRAV=FALSE PREVENTS ANY ANTIGRAV!!!!

THANKS!

I'm pretty sure that caught everybody's eye

But no, MOM is mistaken, WooGLE defaults antigrav to false, even for the initial ambient forcefield, so your Ugly acted properly. Of course I just had to check this just now, I've never made a level with balloons (or Uglies) before so I've never had to change the antigrav attribute for any of my forcefields.

EDIT: Wow I think you got caps lock stuck there.

I thought WooGLE made the ambient gravity in the level antigrav true, and others default to false?

Derp, AP has it right. Thanks, AP.

Yes, I thought so too. But that means balloons won't go the opposite way in small, directed forcefields.

That's true; they won't, unless you set antigrav=true. In the case of a lot of small, directed forcefields, though, you don't want the balloon to be pulled, say, downwards and to the left when everybody else is going up and to the right. It'd just look strange. You'd want it to be pulled in the same direction as all the other Goo Balls.

Yes, i know. I never said that i dont like it.

Yes you did. Look at the italic part of your last post.

That was not me....I did not know it was called italic anyway nice try but using moderator powers is cheating

EDIT pls change it back what if Draft as Brush sees it....

Sorry. But I doubt if Daft will see it, he hasn't been on here for months.

Yeah oh well...But i have to admit that was a nice joke

You're right, dunno why I thought the default ambient was false

Yep, just tried it myself. If they DID, though, it still wouldn't matter.

Well, of course. Only gb2 needs a strand for it to work. But with an Ugly it had better be a fairly long strand...

Never tried that.
Will do it now.

Cool, that way the player can drag the ugly/beauty one time for detaching.
