My npc isn't moving, how do I fix it?

I’m working on a uni project and as part of this we’ve been given tutorials to work off and I’ve been following the one for enemy characters and for some reason my npc isn’t working. it’s supposed to move towards the player when they hit a sphere in the level. I think it might be something to do with the sphere’s collisions but not entirely sure.

Do you have a NavMesh box in your scene?

I don’t think so

Add it and try again. Also i would prefer to use AIMoveTo there you have a couple more options e.g. “Onsuccess”
