1. set doodad state to disable for beacons at X location + create an scanner sweep or a turret or any unit that its detector near it so it gets revealed then remove it if you want and donde glowing beacon effect

if you didn't get it check out the tutorials man sen is so great and for number two i replied one topic today with this hmmm let me go find my quote

QUOTE(Corbo)
that's wrong because the colors blue, black , orange will depend on the tile set
+space, installation, will go blue and no glowing not even on zerg units it will just be static
+ashlands= orange
+desert= some weird black in shades of red..very difficult to see
+badlands, jungle= black to gray
+twilight= nothing? how weird.....
+artic= blue in shades of gray more like light blue that slowsly glows
ok and dtbc got me thinking and once it happened to me but i did some testing
this test was made in Desert i don't know if it affects it but here it is:
3/1=2/1 2/1=2/1 4/1=2/1 3/1=2/1 5/1=2/1 6/1=2/1 7/1=2/1
3/2=3/2 4/2=3/2 5/2=3/2 6/2=3/2 7/2=3/2
4/3=4/3 5/3=4/3 6/3=4/3 7/3=4/3
5/4=5/4 6/4=5/4 7/4=5/4
6/5=6/5 7/5=6/5
7/6=7/6
things to remember, health depends on tileset
glowing units are zergs, resources, critters and some powerups and beacons and
archons
not glowing units are terrans and protoss and the ones missing
and remember the chart i made up there
