Alrighty... there was a discussion on 'b' align objects on your map (or is it the 'g' key now?)
https://forum.game-guru.com/thread/222749
So I asked -- "How hard would it be to draw a line on the map and the active entity is spawned all lined up the length of mentioned line? Now that would be a fast convenience. Probably outdoing the AAA littlewigs."

Not too hard. It's potty time! So I decided to do a demo (which I must admit is a bit crude and primitive) because I haven't added the full screen mouse control the GG editor has. So there are several additional controls that could be added upon-- echo; just a DEMO!
*Contains objects perhaps not everyone has, so it's a complete compiled level (w/ no embellishments!)
**Thanks to smallg's getting angles script.
***Thanks to AmenMoses for the > GetEntityPositionX ( e ) < functions... I suspect that's his work. Correct if wrong. What this does is make getting these position values much less lag-prone.

Well... it wouldn't let me upload the .zip file, so oh well.
To clarify what I was attempting to share was a demo on drawing walls (anything straight actually)
from sidewalks to power-lines, streets, etc.
on your map instantly with the mouse. The demo is okay to see the basic precept, but I tried a few
times to upload the compiled map; (228 mb).zip here-- a no go on it said 'error'.

You could put it up here and post a link , download link lasts for up to 30 days if I remember right

Sort of, Lee added them after a few email exchanges we had.

My addition is the GetObjectPosAng( objid ) command.

e.g.:
local x, y, z, xa, ya, za = GetObjectPosAng( g_Entity[ e ].obj )

Then you have all the positional/orientation details for the physical object all from one call.

Okay. Thanks Granada. Checked on that and looks okay.
So here it is (not elegant, just simple functionality demo)
