Hi all
I have been trying to code an npc who follows the player. I have been tearing my hair out - or what is left of it. It probably is a dumb mistake but can’t find it for my life. I can generate a path, draw the path even. However, when I try to use the path to move_and_slide, my npc keeps flitting directions and no actual movements.
I put the screenshot of the navmesh scene and it’s child npc scene below. These scenes are part of a bigger code but I cleaned most of the irrelevant stuff. Any help greatly appreciated
