Grimrock

I've noticed that ogres behave strangely with wall gratings.

This ogre is more than content to stare at me through the grate rather than to walk around it and smash me up.

ogre's have very small brains ;p

the grate is a wall to them. i guess.

Not so, because they turn to face me. they want to attack me because they can see me, but they can't attack through the grating so they just stare at me instead.

so, an (very) advanced mod would be ogre stares at you for a moment then gets angry, rips the grate off and one shots you into the ground

Well if you define the model of a wall grating as an item it becomes throwable.. (or maybe a projectile)

I wonder if this is related to the change that was made on how gratings are shown on the automap?

Gratings are doors for the ogre ai, and doors can't be sidestepped like that in the grimrock dungeon so the ai was never tweaked with this case in mind. It's a "feature"
