Tilemap Collider 2D

You can add the Tilemap Collider 2D component to the Tilemap GameObject to generate Collider shapes for each Tile set in the corresponding Tilemap component. As you add or remove Tiles to or from the Tilemap component, the Tilemap Collider 2D updates the Collider shapes during LateUpdate.

The Collider shapes generated for each Tile in the Tilemap depend on the desired Collider type set in the Tile Asset.

Collider Type Function
None The Tilemap Collider 2D component does not generate any Collider shapes for this Tile.
Sprite The Tilemap Collider 2D component generates a Collider shape based on the Sprite assigned to the Tile. The Collider shape can either be the custom physics shape set for the Sprite or an approximation generated from the outline of the Sprite.
Grid The Tilemap Collider 2D component generates a Collider shape based on the shape of the Grid cell, which is determined by the selected Cell Layout of the Grid component.

Use this Collider in conjunction with the Composite Collider 2D component. To composite the Collider shapes of neighboring Tiles together, add both to the same Tilemap. This smoothes out the corners and edges between the Collider shapes in neighbouring Tiles.

This can also improve the performance for the Tilemap Collider, because fewer individual Collider shapes are involved in a physics update. This reduces the amount of calculations required.

Is Trigger Select this check box to have the Tilemap Collider 2D behave as a trigger.
Used by Composite Select this check box to make this Collider be used by an attached Composite Collider 2D.
When Used by Composite is enabled, all properties except Offset are no longer available in the Tilemap Collider 2D component. Instead, the properties are controlled by the attached Composite Collider 2D component.
Used by Effector Select this check box to make the Tilemap Collider 2D be used by an attached Effector/s 2D.
Offset The local offset of the Tilemap Collider 2D geometry.
