# AutoTile
|
||
|
|
|
||
|
|
AutoTiles match themselves based on the mask set on Textures to generate the AutoTile ruleset. Two types of Masks are
|
||
|
|
available for the AutoTile, the 2x2 type for 16 Sprites and the 3x3 type for 47 Sprites set.
|
||
|
|
|
||
|
|
### Properties
|
||
|
|
|
||
|
|
| Property | Function |
|
||
|
|
|------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------|
|
||
|
|
| __Default Sprite__ | The Sprite set when there are no matches. |
|
||
|
|
| __Default GameObject__ | The GameObject instantiated when set on the Tilemap. |
|
||
|
|
| __Tile Collider__ | The Collider Type used for generating colliders. |
|
||
|
|
| Mask Type | Mask Type for setting Rules for the AutoTile. Use 2x2 for a 16 Sprite ruleset and 3x3 for a 47 Sprite ruleset. |
|
||
|
|
| Random | Randomly picks a Sprite if multiple Sprites share the same mask. Otherwise, uses the first Sprite set with the mask. |
|
||
|
|
| Used Textures | Sprites will be used from the selected Textures to make up the ruleset. You will be able to set the appropriate Sprites by painting the masks on the Sprites. |
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Set up the AutoTile by selecting the appropriate Mask Type and add the required Textures to be used. You can adjust the
|
||
|
|
Scale per Texture to have it sized appropriately in the window.
|
||
|
|
|
||
|
|
Each Texture will have its Sprites outlined as a rectangle. Depending on the Mask Type set, the rectangle will be split
|
||
|
|
into portions, either 2x2 or 3x3. Click on each portion to set a mask on that portion. Doing these sets up the painting
|
||
|
|
rule for that Sprite. Paint masks on each Sprite to set up the entire ruleset for the AutoTile.
|
||
|
|
|
||
|
|
#### 2x2
|
||
|
|
|
||
|
|
Each corner mask must be matched with the same Tiles bordering that corner. For example, if the top right corner is
|
||
|
|
masked, for this to be matched, there must be the same Tiles to its top, top right and right for it to be matched.
|
||
|
|
|
||
|
|
In the below example, the center Tile has the same Tile on all corners except the top left. This matches the mask on the
|
||
|
|
top right, bottom left and bottom right and will use the corresponding Sprite.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
#### 3x3
|
||
|
|
|
||
|
|
Each mask on the borders must be matched with the same Tile for the painted Rule to be matched. The center mask
|
||
|
|
determines if this mask rule is active.
|
||
|
|
|
||
|
|
In the below example, the center Tile has the same Tile on the top, right and bottom. This matches the mask with the
|
||
|
|
borders on the top, right and bottom and will use the corresponding Sprite.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
If two or more Sprites have the same mask painted on, they will each have a red border to highlight this. If this error
|
||
|
|
is not corrected, the first Sprite from the top left will be used when there is a match in the mask.
|
||
|
|
|
||
|
|
You can save the finished AutoTile ruleset as a TileTemplate by clicking on the Save button. This exports the ruleset
|
||
|
|
for the current Texture. You can load the TileTemplate for another AutoTile using a similar Texture with the same layout
|
||
|
|
without having to set up the masks again. The example below shows an AutoTile with a Texture loaded with an
|
||
|
|
AutoTileTemplate created from the AutoTile above.
