My NPC won't move!

Hi

I mustbe missing something stupid, and I’m starting to get annoyed! I created a blueprint for NPCs (I actually modified the third person character template), and set it to move on begin play. I wait 1 second and then call AI MoveTo. It turns in the right direction, but doesn’t go anywhere, it says it’s blocked.

  • I made a new test level and an NPC with the mannequin, which seems to work.
  • I added a NavMeshBoundsVolume, definitely big enough.
  • I turned off collision on the NPCs mesh, so only the capsule collides (Pawn presets).
  • The navMesh agent has radius 40, height 200, and collision capsule has radius 34, half-height 88
  • I made sure “Can ever affect navigation” is unticked

I don’t know what else to try. I even tried to get an AI to explain what I might be missing! Can anyone tell me anything useful I might be doing wrong?

Hi, try using the “Visual Debugger” (Tools menu) - click on the NPC in the list and it will show you visual paths and any errors etc.
