activating script when enemy AI see playable unit

[hogmason 2]

ok so bit of a tricky one just wondering if some one knows how i go about getting a script to run only when the enemy East AI can see a player.

The reason attempting to do a artillery script that will drop artillery on a players position when in contact with the enemy.

I know there is arty scripts out there but they all require artillery battery's on the map.

I have the artillery working just need to figure out how to call the script on a players position

This script could be adapted to that. Check also the TPWCAS thread in addons - complete, a few pages back, somebody modified the TPWLOS script for a similar objective.
