-1 thing?

As I mensioned before, on other topics, I have two computers, one of them with srb2 v1.09.2.
The thing is, that, on that computer, I was seeing all things on SOCEdit, when I saw a ROCKET thing. Questioned, I saw what type of thing that was, and it was -1.
I added it on a map, and the results where a green, inmovable sonic, that just stood there.
What I did next, looked like it was ment to be done.
1-I started a 2p game on zim's base, and switched it to the map.
2-I removed splitscreen, and turned on objectplace.
3-I tossed a ring to the green Sonic, and he stood on the "dead" animation.
4-I turned objectplace on, and put many rings on the way, collecting them all.
5-Then, on all the places that where previouslly rings, now where green Sonics! But these ones where invincible and untouchable.
Intriging.
I only managed to do this on srb2 v1.09.2; and I couldn't do that on v1.09.3.35.

Because -1 means that It Doesn't show the Thing In objectplace mode.

I tried that once And It doesn't work.

For example:

A -1 thing Is A player, eggmoble rocket, and goop.

And they won't be seen In objectplace mode.

-1 is for any object that you don't want to be placeable with a map editor.

-1 is also RedXVI...

Like I said, anything you can't place in a map editor. >.>

how d' ya remove splitscreen?

What does that have to do with this topic?
Splitscreen 0 in the console or start a new 1-player game..
