The problem is that most traps don't really make sense for enemies to trigger them. Traps that trigger scenes like the Tentacle or Slime one or traps that give effects that only effect the player like chastity or gender TF would just do nothing.
One thing that I could add is having the traps only trigger if the player is able to see/placed them and only if the traps does make sense to trigger.
If I remember correctly, enemies in the original try to avoid traps as they are able to "see" them, but I don't really want to implement that...
