When I create “Blueprint Top Down” project my character moves by mouse clicking on Example_map only. If I create new map for this project, there is no character feedback.
Blueprint graph seems to be ok:
Probably because you haven’t defined a navigation mesh for your character. Check out the Scene outliner and type in “NavMesh” to reveal a NavMesh BoundsVolume and a RecastNavMesh. Even so, make sure the player is within those bounds or that you extend them as far as needed if you want the character to go beyond those four walls.
You could also copy the Example_Map and work from there instead of always creating the new level from scratch.

thanks a lot
