Make monsters not have "Infinite Vision"?

[Graaicko]

Hey, I was wondering if there is a way to make enemy actors have limited vision instead of see you from infinity for example, you are in a large area and enemies can't see you from a far without using Doom builder Lindef blockers. I have not seen this ever before in a Doom mod, But I was wondering if its possible? I am specifically wanting to make it effect enemies via slade if possible. Thanks.

A_LookEx can take maximum see distance as a parameter.
Setting it to a value like 512 will make monsters not see the player from over 512 units away.

Hmm, Didn't think It would be this easy. Now can this be adjusted, for example maybe if 512 was too far or too close?

Yes, A_LookEx is customizable.
minseedist sets the minimum distance required to see the player, so if this value is 256 and the player is closer than that, the monster won't see them.
maxseedist sets the maximum distance required to see the player, so if this value is 256 and the player is further than that, the monster won't see them.

I played around with A_LookEx, I can't seem to figure out what number values do what. Would you be able to dumb it down for me?
A_LookEx(0, 0, 0, 0, "See")

It's right there on the wiki page: A_LookEx

A_LookEx (int flags, float minseedist, floatmaxseedist, float maxheardist, double fov, state label)

minseedist sets the minimum distance required to see the player, so if this value is 256 and the player is closer than that, the monster won't see them.
maxseedist sets the maximum distance required to see the player, so if this value is 256 and the player is further than that, the monster won't see them.

The distances are in map units (a door is 128 units wide).
