Title: Mobs Ignoring Wall Collision – Geodata Problem?
Post by: Noza on January 15, 2026, 02:39:52 AM

I ran into this issue, but I’m not sure whether it’s a geodata problem or an issue with the mobs’ AI. I generated the geodata using //ge, taking into account only the small wall that is before the cliff.

Should I redo the entire node again, or should I look into the NPCs’ AI? As can be seen in the video, the player cannot cross the wall.

Has anyone else had this problem?

No, it still happens the same way, I already did a clean installation of everything.

Not a geodata issue.
The player moves too far away and monster makes multiple turns.

Try this.
