Why won't enemies attack?

[Asking4Id]

So this is a question from a newbie who's just started using Doom Builder 2 (fooling around with it really). When I place enemies, save, and then play the wad, everything seems fine until enemies move around. Then it becomes clear they won't fire back. They just walk around. What can the reason be? Tested my custom wad with Doom 1 as base. Used Doom editor within Doom Builder 2. Played the custom wad on Crispy Doom.

I know strange things can happen if your map has only one sector.

That sounds like it's not building REJECT (precomputed line-of-sight data), so enemies never think they have line-of-sight to you. It works fine for me with stock Doom Builder 2. Press F6 > select game > Nodebuilder. Mine uses the default ZenNode setup. Did you change that part?

I don't know what might be the problem, but there may be a possibility that you put them as being friendly. It's probably not the case, but it's another reason why monsters won't be able to attack.

Did you set the proper flags for the monster?

 

 

Monsters are activated by line of sight, hear noise or being bumped.

Also make sure they have room to move around. I noticed monsters will constantly move and change direction and hardly ever attack if they are in a tightly enclosed area.

IIRC Doom's AI either turns or attacks. It can't do both at once.
