Is there a way to make biters totally not attack something?
I'd like them to totally ignore rail.

Thanks.

If you mark the entity as indestructible they won't attack it. https://forums.factorio.com/wiki/inde ... structible

I added the below, but did not seem to work. It also did not crash though What is the correct syntax?

It's not prototype field, it's entity field. You need to do that when they are built.
Other way to try would be to remove "player-creation" from the prototype flags in definition or rails.

I think you want to create a new force, (by default there are 3 forces, player, neutral, biter) and assign the rail entities to the new force. Alternatively, assign the rails to the neutral force. Biters should ignore entities not part of the player force.

Note: I have not tested this, I only speculate forces will work (as delineating ownership is their purpose)

Biters will still chew their way through neutral/non-player entities to get to their target. So this might work for rail because that won't be in the way, but not for other structures that might block the biter's path.

Huh, is that actually an actual "chewing" behavior? I always thought biters just damaged structures that they passed too closely to.

They have to actually attack something if they want to damage it, yes. They don't tear down walls by just looking at them funny.
