In Tiled, a ‘flag’ property is used on Tiles in a tilesheet to mark them for a particular purpose.
Tile.flags='nonclick,impass' TileSprite.nonclick TileSprite.impass
nonclick means that the Tile is will not register a move-click (which is a click intended for moving. While testing using Kenney’s dungeon Sprites, I found a Sprite that arched above the ground (eg a pull up bar). Clicking on the top of the bar would have yielded a movement towards the Sprite’s location, when in fact, the player might have wanted to go to the Tile above that. So I put in the ‘nonclick’ flag to keep certain Sprites from registering a move-click.
impass means that this Tile is not meant to be moved on.
