Invisible spobs?

Can it actually be done?

I ask because when I set the spob to not use a spin, ie Type -1, it crashes nova just after nova finishes loading. I looked at my debuglog and it doesn't show much of anything unexpected. Can anyone give me some advice?

Make an invisisble sprite and use that.

But how? What, should it be black or what?

Oh, wait. I guess that if the mask was all black, that would work. Ok, thanks.

It did work. Thanks JTH.

No problem.
