I found this and I did it in this simple test map. I protected it, not because I want to keep it for myself, but because I am working on a map with it right now. I will reveal how to do it after I release the map.
Here are some screens.

You never thought it was possible did you?

What good is this for us if we won't know how to do it.
is it just the simple way
create units[loaction]
order unit to move to[location]
disable unit at [location]
wait 10
enable unit at[loaction]
wait 10
move unit at[location] to [location]
is it just that simple processdure exspet for the egg's and what ever else does't have legs or can fly
Try that way yourself on a goliath.
oh well good point well teach us how u did it there pella i need to learn something new on here

It's called p161 trick used with an Arbiter.... Well I'm not sure since arbiter have shadows under them...
Hey wait a minute... Why BC don't have shadows too? Sprites?

The player 161 trick will only work once per game, and it's quite buggy and Paella said he did it without encoutering bugs.
No triggers
No Sprites
Just Units
wait a sencond that make no sense then how the hell do you do it are the units able to move or do they just have to stand there?
It's invisiable arbiters or something. The units uncloak of you move them to certain areas on the map.
EDIT: And as far as I can tell, Dianamoth is never cloaked.
You're right, the arbiter never can cloak, I was just testing it. So how did I do it, I know that one of you will figure it out.
ok but were are the abitars they aren't near the units at all as i see in the pic but i might be wrong

I would guess that you found some extended player that effects other players, and has intangible units... or just figured out some way to make them intangible.
EDIT: Or cloaked and invinsable.
could u put that in simpler forum so sum of us none smart people can understand chill
I will if it turns out I'm right. I'm not going to bother explaining something in depth if I'm just wrong.
oh ok well i hope your right so i can learn w/e the hell u said up there
Er, I guess I don't mind explaining what I meant.
Intangible Units: Units that cannot be clicked on, or seen, or anything.
Invincible Units: Units that are invincible. You cannot attack them or cast spells on them, but you can click on them and stuff.
Arbiters: Units that cloak stuff around them.
Extended Players: Players thirteen and up. They usually do weird things to StarCraft (2x, 4x speed, cloaking/uncloaking units).
Better?
I didn't think it was, it was just the best I could think of at the time. Anyone else have some ideas they wanna share?
EDIT: Of* not or. Why is it that there is a minor spelling error in every single one of my posts? Why!?
well... There is a Nexus... Why?... Hum.. Strange!
this cloaking thing has got me all confused iv been trying to figure it out for the last 2 hours SO JUST TELL US ALREADY dang u

Just to tell you, player 161 would be more stable than using extended units. These units are not permanently cloaked.
I can make them perm. Cloaked, but I didn't in that map. THAT IS A HUGE HINT!
There must be an extended player that always has invisible units, because it's like each group of units stayts cloaked. But, if you take a unit out of the group (And far enough away from the others) it will uncloak.

Open the map, try it out, and see if you can find anything that looks out of the ordinary, otherwise, if you're patient, like myself, I would just wait until he's ready to tell everyone.
