I don't know if anyone else has found this out before, but I just thought I'd mention it.
Using Reyk's wonderful Editor, I found out the following:
1)if you place an object as a player (let's say player 2-not Gaia), and then place terrain down, in game player 2 will be able to see that placed terrain-area, as if though he had units there.
2) when you place down buildings-terrain and stuff, and it's time for playtesting, you can use the editor to switch to player #-whatever the player is going to be, and then press the button move object and then pick a previously placed unit and order (right click) it to move. This way you can see the path it'll take and if it can go over some terrains.
3)While placing gaia buildings and enlarging them, I found out using the method I describe in (2) above, that enlarged buildings keep their original size in "space occupation".
So to solve this and not allow units to move through the walls and such of enlarged buildings, I used the brush at size 1 and placed underneath cliff terrain. Problem solved.
The same must be done with some objects -like Osiris Pyramid Dead- which are like holograms in the game and units just go through them at will.
4) Also, while in Reyk's Editor, if you're already player#, you can move objects of same type -i.e. destroyed buildings medium- by double clicking on one of them. Nothing great, but saves time when you want to move a lot of things to somewhere else.
As pftq wrote: You can move multiple units (Move Object effect) by simply selecting them and then holding down the middle mouse button or scrollwheel.
Let me add to that, you can also move several objects belonging to different players while in Editor, by clicking on each one of those objects and press-holding alt at the same time.
5) Hovering bird trick:
place a bird-type gaia unit of your choice (vulture I prefer), and when it starts to move away, place a TC just on top of it. Last night I did it and the damn thing was "captured" by the gaia unbuilt town centre and now it just stays there hovering above the centre.
maybe I'll try to get a whole bunch of them caught like that, but unfortunately they just flap wings and stay there, just as when you place gaia ravens.
6) Enlarging objects: (use K in the editor and shift+K for shrinking)
Some objects -like rocks, destroyed buildings, etc.- don't have a limit on enlargement.
"Productive buildings" -like TCs, farms, etc.- do have a limit on enlargement, and if enlarged too much they disappear !!!
7) UPSIDE BUILDINGS:
When you flip a building upside down using Reyk's Editor, the building disappears and you can only see it's "shadow" on the map, but it can be attacked.
Point of note, the building cannot "produce" -i.e. cannot place a unit created (that's the message I got from upside TC and Temple while I tested).
I intend to write down all the tricks I find along the way, so that newcomers to designing will be helped and not waste a long time on finding out by themselves as I did, by mostly trial and error.
