Forgot how, i got the trigger, but cant remember everyything to it, can smeone help me pleaes?

Player: Unit who owns building
Conditions: Always -> Always
Actions: Set Doodad state -> Disable Doodad state for building owned by player at 'location'

Disable Doodad State, and then you must have vision (detector or better) with it. If you just want the overlay, you remove the detection/vision.

sorry i dont understand

Use the trigger action "Set doodad state" and disable the state of the Terran beacon.
Next you have to somehow give the human players vision.
You can do this by creating a unit that is a detector, Protoss observer/Terran Missile Turret, and then removing it.
Or you can do it via triggers.
The trigger action "Run AI Script" allows you to change the shared vision settings. Simply change it so that the players have vision of the owner of the beacon and then wait 0 seconds, and then turn it off.

Bada - bing - bada - boom.

i got the trigger, theres 8 beacons, it only worked for 1 and then i copied the disable doodad state trigger 7 times but it still wont set the other 7

1. disable doodad state of the beacon (directly chose the beacon type)
2.
A: if the player has no detector near the beacon or shared vision with the owner -> unclickable beacon
B: if the player has a detector (observer, missile turret, ...) near the beacon or got shared vision with it (enable shared vision with beacon owner, wait 0, disable the vision -> does not reveal anything most of the time, at least never at mapstart) -> cloaked beacon

for multiple beacon you need to give it to another player after disabling.
e.g.: disable 3 beacons in 1 location:
1. disable a beacon
2. give to another player (e.g. neutral)
3. disable a beacon
4. give to another player (e.g. neutral)
5. disable a beacon
6. give to another player (e.g. neutral)

k i got it, thanks guys

Although you got it already, for future reference don't forget the maplantis stuff when the wiki fails you:
