Tile Movement: Can Move To?

Hi yall,

I read through the guide of the Tile Movement behavior, and it said the following;

TILE MOVEMENT CONDITIONS Can move to Test if the object can move in to a grid cell, given by its grid column and row. This is true if the cell is clear of any obstacles.

What counts as an "obstacle" and how do I define it? Because as if right now it is acting as if there are no obstacles, So I don't understand 100% how this condition works?

Any help, tips or advice will greatly be appreciated!

If you give the Tilemap object the Solid behaviour, then any filled in tile becomes an obstacle that blocks the player movement.
