Tiled2Unity: Tiled Support for Unity
Please consider supporting Tiled Map Editor on Patreon. Tiled is a free and essential tool for 2D game development and I’d like to see the author support it and similar tools fulltime. We’d have no Tiled2Unity without it.
Tiled2Unity is a free utility with one goal in mind: Easy exporting of Tiled Map Editor TMX files into your Unity projects. Tiled2Unity takes your Tiled files and creates Unity prefabs from them that are easily placed into your Unity scene. Complex collision is supported through Unity’s PolygonCollider2D class. (Windows and Mac)
Tiled2UnityLite is a command line version of the Tiled2Unity utility. It can be used on any platform but was primarily designed to give Linux users a way to use Tiled2Unity on their operating system.
When you install a new Tiled2Unity version you will also want to update the Tiled2Unity scripts in your Unity project folder as well. The easiest way to accomplish this is through the Import Unity Package to Project menu item while your project is open in Unity.
Note: Both the Tiled2Unity output window and the Unity console will complain if there is a mismatch.
All Source is Freely Available on GitHub
Tiled2Unity is made up of two parts:
- The Tiled2Unity utility that exports a Tiled file.
- The Tiled2Unity Unity scripts that imports the
*.tiled2unity.xmlfiles and puts the textures, meshes, and prefabs into your Unity project.
Both components are publicly available on GitHub.
I’ve tried to make Tiled2Unity simple to use and understand. Here’s some links that may help you out:
- Introduction: Use the test TMX files supplied with Tiled2Unity to create two simple scenes in your Unity project (one with sloped collision).
- Tiled2Unity Scale: By default, Unity 2D sprites use a coordinate system where 100 pixels equals 1 unit in Unity. I think that’s crazy but this link will show you how to live in that world.
- Mega Dad Adventures: A good number of “advanced” examples of using Tiled2Unity in your Unity projects. Set tags and layers on your imported prefabs and add custom, game-specific behavior.
- Tile EdgeCollider2D Support: Shows you how you can use polylines in the Tile Collision Editor to export EdgeCollider2D objects in your Unity prefab.
- Getting Tile Information at Runtime: Useful for Strategy and RPG style games.
- Introducing Tild2UnityLite: Use Tiled2Unity as a command line utility on PC, Mac, or Linux.

- Bug Fix: Tile Objects in Isometric maps have their position and collision geometry properly set now.
- Bug Fix: Recently added support for Object Types introduced a crashing bug when using
- New Feature: Object Types now supported. Default property values for Objects will be exported to Unity.

- New Installer: The NSIS-based installer was being falsely flagged as malicious by some anti-virus software. Now using an MSI installer package.
- Improved reporting: Will now be warned if you try to export a Tiled map that has a
PolygonCollider2Dthat is “too complicated”. (This usually means you set up colliders in Tiled without using “Snap to (Fine) Grid”.
- Bug fix: Removed GDI+ library dependency that was crashing some Mac users in Tiled2UnityLite.
- Bug fix: Fixed crash with Tiled maps that contain only Image Layers.

- Bug fix: Fixed crashing bug when extra tile data remained in a TMX file for a tile that has been removed from a tileset.
- Bug fix: Will no longer crash if
unity:sortOrderproperty value is not an integer (reports an error instead).

- Improvement: Tiled2Unity can be used in WebPlayer builds again. However, you must import your Tiled maps using another build target first (Standalone Windows/Mac/Linux will do).
- Bug fix: Fixed compile error with Unity 5.0
- Bug fix: Fixed string exception being thrown when (re)importing Tiled2Unity.xml.txt marker file.
- New Feature: Added support for unity:resourcePath custom property on Tiled maps. This instructs Tiled2Unity to build the map prefab at
- Bug Fix: Fixed bug with importer getting stuck when saving a prefab to the Resources folder.
- Bug Fix: Replace compile error CS0234 with notification that Unity Web Player is no longer supported.
- Bug Fix: Fixed compile error when importing with earlier versions of Unity 5.x (5.0, 5.1, and 5.2)
- Big Fix: Fixed compile error when building the Unity player.
- Bug Fix: Textures used only for Tile Objects were not being exported to Unity

*.tiled2unity.xmlfiles is now significantly faster, especially for larger maps.
- Bug Fix: Colliders on Tile Objects now alligned properly with the origin of the Object.
- New Feature: Tile Objects now supported visually.
- Deprecated: Unity 4.x versions no longer supported.
- Bug Fix: Tiles that were rotated and/or flipped could introduce seams depending on camera settings.
- New Feature: Tileset Offset property is considered in placing tiles (Note: This could lead to overlapping tiles that don’t sort as you may expect. Prefer to use Layer Offset instead.)
- Modified Feature:
unity:ignorecustom property can be assigned to
true(ignores whole layer),
collision(ignores collision on layer but exports visuals), and
visual(ignores visual tiles on layer, exports collision only).
- Bug Fix: Image Layers with no image no longer crash Tiled2Unity
- Bug Fix: Fixed compile issue with older versions of Unity
- New Feature: Tiled Image Layers are now supported.
- New Feature: Layer Opacity is now supported.
- New Feature: Layer Horizontal and Vertical Offset is now supported. (Currently only in the Tiled daily build. Will automatically work in Tiled2Unity when feature goes live.)

- Bug Fix: Scripts updated for Unity 5.1 (previous versions of Unity 5 and Unity 4.x are back supported).
- New Feature: Tiled2Unity now works at any location in your Unity project. It no longer has a hard-coded dependency on being located at
- New Feature: Add the
unity:resourceproperty to your collection of Map properties in Tiled so that the prefab is saved to the
.../Tiled2Unity/Prefabs/Resourcesdirectory. This allows you to instantiate the prefab via script in your Unity game.
- Potential Bug Fixes: All
DLLImportunmanaged code has been removed from the Tiled2Unity utility. This should make life easier on anyone porting Tiled2Unity to a non-Windows platform.
- New Feature: Isometric and Hexagonal maps now supported.
- Bug Fix: Using NonZero polygon fill rules when combining collision geometry now so that overlapping polygons don’t create holes.
- Bug Fix: Some animated tiles were still broken when using vertex scaling.

- New Feature: Added Preview Options to previewer. Improved the look of collision geometry in the previewer.
- New feature: Object rotation now supported.
- New feature: New
unity:collisionOnlyproperty on Tiled layers will export only the collision data from the given. Meshes will not be generated.
- Improvement: Previewer no longer contains seams when using zoom.
- Improvement: UI added for modifying vertex scale. No longer have to rely on
-–scalecommand line arguments alone.
- Bug fix: Tiled2Unity would crash if you entered a value for a boolean property which didn’t resolve to
- New feature: Vertex scaling through command-line argument (
-–scale). The vertices of the exported maps and collision maps will be multiplied by this value. For some users this will be a better way to control the size of map instead of scaling the whole prefab.
- New feature: Texel bias setting exposed through command line-argument (
-–texel-bias). This helps when using some shaders that under certain conditions give the appearance of seams in the tiled map.
- Bug fix: Exporting would crash if you had a Tile Object in an Object Layer that had no custom properties.
- Bug fix: Gizmo selection of TiledMap prefab takes scale into consideration.
- Bug fix: TMX files with extra period characters in the file name are supported.
- Bug fix: Texture files referenced by Tiled maps with extra period characters in the file name are supported.
- Bug fix: Gizmo selection of TiledMap prefab now takes world position of game object into account.
- New feature: Preview in Tiled2Unity exporter supports 1/8th to 800% zoom. Allows preview of maps that were once too large to preview.
- New feature: New
unity:ignoreproperty allows you to have layers in Tiled that are ignored by the exporter.
- New feature: New
TiledMapcomponent is added to imported map prefabs automatically, containing dimensions of map.

- Bug fix: Added a bias to generated texture coordinates. This should resolve issues with seams that some users were seeing.
- Bug fix: Unity was renaming our generated meshes under some conditions.
- Fixed bug where textures with whitespace in their name we’re not being assigned to their matching material and meshes during import.
- Exported *.tiled2unity.xml files are always re-imported now when exported, even if the data hasn’t changed.
- Fixes texture coordinate bug with some flipped or rotated tiles.
- Tiles (including collisions) that are flipped or rotated in Tiled Map Editor are now supported.
- Tiled maps with flipped or rotated tiles no longer crash Tiled2Unity.
- Several speed improvements. Useful for viewing and exporting “large” Tiled maps.
- Polylines added to tiles in the Tile Collision Editor (in Tiled) are exported as EdgeCollider2D objects.
