There may be an extremely simple solution for this, but I need to know how to place independently cloaked zerg eggs (that means no arbiters). I use starforge and scmdraft2 and simply enabling the "cloaked" property of the egg doesn't work. "Disable doodad state" also no luck (the egg sprite just glitches out and disappears). Any solutions?

I'd stick with impossible.

I have seen it done, but I don't know how.

Try different tilesets.

Well... theoretically it isn't possible. EUDs?

Sorry if I am behind the times with new patches and stuff (haven't mapped in about a year), but didn't they disable EUD trigs at some point in time?

Yes. EUDs wont work.

maybe the egg was just a hydra that did the burrow cloak glitch then started transforming into a lurker (with like 9999 for the lurker transform time)

so hydra + burrow cloak + inf. time lurker trans = Cloaked zerg egg?

I actually made a simple map just now just to try that. It did work, but I need quite a few of these cloaked eggs in my map and that method isn't gonna cut it. Thanks for that insight though, but I need a solution that directly places such eggs on the map.

Technically you can do that but there's little to no chance of being able to do it with a CPU. Not unless you go through an extremely delicate process of triggering to unburrow / create burrowed units, moving an arbiter and timing it all correctly. Unfortunately even with that you won't be able to make the Hydra turn into an egg for the Lurker.

The best way to do this is to place the egg in game next to a mountain region or somewhere with no vision and float an arbiter over that area and close enough to cloak the egg without being seen itself.

whew, yes I just finished trying my techniques on every single tileset. Thanks for the advice, but none of the tilesets made a difference. Oh well, keep the solutions coming though. I'm now really curious to know, because it seems like such a simple thing to do.

Yes, that would definitely work. However, the premise of my map doesn't involve a bunch of eggs in an obscure corner. they are actually spread somewhat sparsely throughout the map. Thanks for the advice though. Keep em coming.

Rapidly replace the egg using hyper triggers.

If that was sarcasm, you're my new favorite senner.

Haha. That would work in certain situations but I need them to be physically cloaked (as in units won't shoot at them when they walk past with no detectors).

If you move an arbiter-cloaked egg to where you need it, it will be cloaked for a short period of time

Have you tried all those enable-wait-disable-etc. tricks?

Btw. just the EUD actions were disabled. EUD conditions still work, but I don't see a way how conditions could help you here.

If he continuously moved it then other units would have a hard time acquiring a target on it, so that's out of the question, IMO.

Now, while you said disabling doesn't work, just as Nude said, try disable enable enable, that MAY cloak it, if that does not work, then you have one last option:

Cloaking a hydralisk is really not that difficult, all you need to do is create it underneath an arbiter, burrowed, and then order it to move, and it should immediately come up cloaked. The problem is getting a computer to decide to morph it, which I have no idea how to do, you're on your own for that one.

Thanks for the suggestion of disable/enable, but I tried, and that put the egg back to normal state (not cloaked). So I guess I'm stuck with the "last option". I messed with AI scripts a bit to accomplish it, but... I'm really not that good with custom AI scripts. Didn't get very far... Even if it did work though, it's pretty impractical because I need around 30-40 such eggs in my map, and to implement an time-efficient system (means 1 arb-hydra group for each egg executing simultaneously) would be insane (imagine # of locations and scripts involved with creating and relocating eggs etc).

Yes, you won't reliably be able to make the computer train lurkers just when you need it.

Don't know why you need em cloaked but maybe it's enough to place a burrowed unit under an invincible egg.
Or move the eggs there when you need them (pseudo cloak )

Well, maybe you could trick the player to do the Lurker morph thing.
Maybe implent a save/load system, a character/game options choose system, something like that.
Heck, you could even make it a mini-game: the first person who morphs 30 Hydra's into Lurkers wins!

EDIT:
I'm not sure if you can cloak larva's easily but using a normal AI on a couple of Hatcheries you can easily make 30-40 eggs within a minute (depending on how much space you can use for Hatcheries).
