A_Look [(int flags[, float minseedist[, float maxseedist[, float maxheardist[, float fov]]]])]

Causes the monster to check its field of vision for any targets.

• flags: Unused at the moment. Should be set to 0.
• minseedist: Minimum distance (in map pixels) the target must be from the actor in order for it to be seen.
• maxseedist: Maximum distance (in map pixels) the target can be from the actor for it to be able to see it.
• maxheardist: Maximum distance (in map pixels) the target can be from the actor and still be able to hear gun fire.
• fov: The field of vision for this call in degrees. Default is 180 degrees.

ECWolf implements A_LookEx as an alias of this function. This alias can be used if compatibility with ZDoom is desired.
