Свойство: Функция:
Tile Displays the Tile currently set at the selected cell location. If you select multiple cells, and they display the same Tile, then that Tile’s name is shown. If you select multiple cells with different Tiles, this property is blank.
Sprite Displays the Sprite assigned to the Tile in the Tile property above. If you select multiple cells with the same Tile, then this displays the same Sprite. If you select multiple cells with different Tiles, this property is blank. This is grayed out by default, so you cannot edit it.
Color The vertex color of the Sprite. This is grayed out if Lock Color is enabled, so you cannot edit it.
Collider Type The Collider Type of the Tiles at the selected location. This is grayed out by default and cannot be edited.
The Transforms (Position, Rotation, Scale) are grayed out if Lock Transform is enabled and cannot be edited.
Position Enter the offset (in cells) for each axis to shift the Tile Sprites along the respective axis. The Tiles’ actual cell positions on the Tilemap remain unchanged.
Rotation This rotates one or more Tile Sprites at the selected location. Enter the rotation (in degrees) for each axis to rotate the Tile Sprites around the respective axis. The Tiles’ actual cell positions on the Tilemap remain unchanged.
Scale Scales the size of one or more Tile Sprites at the selected location. Enter the factor for each axis to scale the Tile Sprite by along the respective axis. The Tiles’ actual cell positions on the Tilemap remain unchanged.
Lock Color Select this to prevent changes to the Color of the Tile, and clear this to enable the Color property. When this property is grayed out, its state remains fixed. See the Tilemaps.TileFlags set in the Tile Asset to modify this property.
Lock Transform Select this to prevent changes to the Transforms of the Tile, and clear this to enable the Transform properties. When this property is grayed out, its state remains fixed. See the Tilemaps.TileFlags set in the Tile Asset to modify this property.

Modify Tilemap

The Modify Tilemap drop-down menu provides different options for inserting or removing rows and columns of blank cells onto the Tilemap. After selecting one of the drop-down menu options, enter the number of rows or columns to insert or remove into the box and select Modify.

The following table describes each option, with links to examples showing how they affect the Tilemap. All examples are based on the following Tilemap.

This is the default Tilemap that the examples are based on.

Свойство: Функция:
Insert Row Inserts one or more rows of blank cells at the selected location. Existing cells are displaced upward along the positive y-axis.
Insert Row Before Inserts one or more rows of blank cells below the selected location. Existing cells are displaced downward along the negative y-axis.
Delete Row Removes one or more rows of cells at the selected location and above. Existing cells above then collapse down to fill the space left by the deleted rows.
Delete Row Before Removes one or more rows of cells below the selected location. Existing cells below then shift upward along the positive y-axis to fill the space left by the deleted rows.
Insert Column Inserts one or more columns of blank cells at the selected location. Existing cells are displaced to the right along the positive x-axis.
Insert Column Before Inserts one or more columns of blank cells to the left of the selected cell. Existing cells are displaced to the left along the negative x-axis.
Delete Column Removes one or more columns of cells at the selected location and to its right. Existing cells then shift to the left along the negative x-axis to fill the space left by the deleted columns.
Delete Column Before Removes one or more columns of cells to the left of the selected cell. Existing cells shifted to the right along the positive x-axis to fill the space left by the deleted columns.
