x atan2 y
Operand types
Type of returned value
Description
Returns the arctangens of x/y.
Returned value is in degrees, in the range -180 to +180, using the signs of both parameters to determine the quadrant of the return value.

Example
_angle = 5 atan2 3 ..........Result is 59.0362
doWatch is normally sufficient, but the AI often take their time to notice the object and shuffle around until they get a 'lock'. You can use setDir to instantly point them in the right direction, and atan2 helps to work out the angle:
_targetx = getPos targetObject select 0
_targety = getPos targetObject select 1
_watcherx = getPos watcherLoon select 0
_watchery = getPos watcherLoon select 1
_dir = (_targetx - _watcherx) atan2 (_targety - _watchery)
watcherLoon setDir _dir
watcherLoon doWatch targetObject
The loon will instantly turn to face the target object and the doWatch command ensures the AI continues to watch the target.
