I'm using this tutorial: https://www.thebotanistgame.com/blog/2020/05/01/raycasting-astar-in-godot.html
I get an error where 'vec' is returning null in this line:
func normalize_point(vec): return Vector2((round(vec.x / GRID_SIZE) * GRID_SIZE) + (GRID_SIZE/2), (round(vec.y / GRID_SIZE) * GRID_SIZE) + (GRID_SIZE/2))
Could anyone help?
I would start by backtracking: add a print statement at the places where normalize_point() is called.
