Check if player has vision?

[Krakenn99]

Is it possible to detect if a player has vision over a unit or building. I want to order an AI Unit to attack buildings and units only if it has vision over them OR it has already explored them, is it possible and how can I do that?

I wan to avoid using aquisition range!

Keep in mind I have only average GUI/Trigger knowledge so no Jass please.

• ((Triggering unit) is visible to Player 1 (Red)) Equal to True
• ((Triggering unit) is fogged to Player 1 (Red)) Equal to True
• ((Triggering unit) is masked to Player 1 (Red)) Equal to True

Probably some combination of checks with these.
