# 2D Tilemap Extras
|
|
|
|
The 2D Tilemap Extras package contains reusable 2D and Tilemap editor scripts which you can use for your own Projects,
|
|
and as the basis for your own custom Brushes and Tiles. You can freely customize the behavior of the scripts to create
|
|
new Brushes that suit different uses or scenarios. To find these additional Brushes, open the Tile Palette window (menu:
|
|
__Window > 2D > Tile Palette__) and open the Brush drop-down menu near the bottom of the editor. Select from the
|
|
available Brush options for different effects.
|
|
|
|
|
|
|
|
The source code for these scripts can be found in the
|
|
repository [2d-extras](https://github.com/Unity-Technologies/2d-extras "2d-extras: Extras for 2d features"), and
|
|
examples of the implemented scripts can be found in the sister
|
|
repository [2d-techdemos](https://github.com/Unity-Technologies/2d-techdemos "2d-techdemos: Examples for 2d features").

|
## Scriptable Brushes
|
|
|
|
- [GameObject](GameObjectBrush.md): This Brush instances, places and manipulates GameObjects onto the Scene. Use this as
|
|
an example to create Brushes which targets GameObjects, other than Tiles, for instancing and manipulation.
|
|
|
|
- [Group](GroupBrush.md): This Brush picks groups of Tiles based on their positions relative to each other. Adjust the
|
|
size of groups the Brush picks by setting the Gap and Limit properties. Use this Brush as an example to create Brushes
|
|
that pick Tiles based on specific criteria.
|
|
|
|
- [Line](LineBrush.md): This Brush draws a line of Tiles between two points onto a Tilemap. Use this as an example to
|
|
modify Brush painting behavior to make painting more efficient.
|
|
|
|
- [Random](RandomBrush.md): This Brush places random Tiles onto a Tilemap. Use this as an example to create Brushes
|
|
which store specific data per Brush and to make Brushes which randomize behavior.
|
|
|
|
## Scriptable Tiles
|
|
|
|
The following are the [Scriptable Tiles](Tiles.md) included in this package. You can create (menu: __Create > Tiles__ )
|
|
the following additional Tile types that are included with this package.
|
|
|
|
- [Animated](AnimatedTile.md): This Tile runs through and displays a list of Sprites in sequence to create a
|
|
frame-by-frame animation.
|
|
- [Rule Tile](RuleTile.md): This is a generic visual Tile that accepts rules you create with the __Tiling Rules__ editor
|
|
to create different Tilesets. Rule Tiles are the basis of the Terrain, Pipeline, Random or Animated Tiles. There are
|
|
different types of Rule Tiles for each of the [Tilemap grid types](https://docs.unity3d.com/Manual/class-Grid.html).
|
|
The default Rule Tile is only used with the Rectangle Grid type Tilemap, while the Hexagonal and Isometric Rule Tiles
|
|
are used with their respective Grid types.
|
|
- __Hexagonal Rule Tile__: A Rule Tile
|
|
for [Hexagonal Grids](https://docs.unity3d.com/Documentation/Manual/Tilemap-Hexagonal.html). Enable the **Flat Top**
|
|
property for a Flat Top Hexagonal Grid, or clear it for a Pointed Top Hexagonal Grid.
|
|
- __Isometric Rule Tile__: A Rule Tile for use
|
|
with [Isometric Grids](https://docs.unity3d.com/Documentation/Manual/Tilemap-Isometric-CreateIso.html).
|
|
- [Rule Override Tile](RuleOverrideTile.md): This Tile can override Sprites and GameObjects for a
|
|
given [Rule Tile](RuleTile.md) to provide different behaviour without changing the original Rules.
|
|
- [Advanced Rule Override Tile](AdvancedRuleOverrideTile.md): This Tile can override a subset of Rules for a
|
|
given [Rule Tile](RuleTile.md) to provide specialized behavior, while keeping the rest of the original Rules intact.
|
|
|
|
## Other
|
|
|
|
- [GridInformation](GridInformation.md): A simple MonoBehavior that stores and provides information based on Grid
|
|
positions and keywords.
|
|
- [Custom Rules for RuleTile](CustomRulesForRuleTile.md): This helps to create new custom Rules for the Rule Tile with
|
|
more options. |
