Option to export each polygon collider as a separate collider gameobject.

[tivec]

Hello!

I have this map being exported from Tiled to Unity via this tool: http://i.imgur.com/3AL4UPP.png

When this prefab is loaded, the collider that was generated will be one of two paths under the same game object. What I would like to see is an option to export each of these two to separate polygons. This would help me out when working with something such as PolyNav2D.

Right now I solve this with a script attached to the collider that splits it into child objects, but that's probably not the best way of doing it. Here's the script I use: http://pastebin.com/0Bdv97jB

It splits each path in the polygon and makes a new sub object to the collider gameobject. If this could be done as an option from Tiled2Unity, that'd make it a lot nicer to work with :)

Thanks for a great tool, and keep up the great work!

Tivec, I think what you're asking for is to replace one PolygonCollider2D
with multiple paths with several PolygonCollider2Ds with one path each (or
an option to do one or the other). Is that correct?

I think your approach is the right one, provided you make it a custom
importer script that is done at export time instead of something performed
at runtime in the behaviour's Start method.

That way when you export your Tiled maps you will have automatically
created prefabs with all the components you need ready to go. Any other
game-specific logic you need for your maps can be set up there too.

You can read about custom import scripts here:

Make sure that such custom scripts have the CustomTiledImporter attribute
and are placed in an "Editor" folder (those are common mistakes).

Best,
Sean

I'm sorry for taking so long to respond. I solved the issue by writing a custom importer that splits the colliders into new seperate ones, and I think that it works fairly well. Thanks again for a great tool that helps production in Unity lots :)

Glad it worked. Thanks, Tivec.

@tivec Are you willing to share that with us?

[tivec]

Of course! My script is fairly simple and should be quite easy to understand. I should also set a disclaimer: I am barely adept with C#, and there may be poorly written code in the snippet. You have been warned!

You would have to customize it if you want to handle anything except the layer "Walls", but the idea is the same :)
