Support / Re: PolyNav with TileMap

« on: January 28, 2015, 05:33:49 pm »

Hello again,
I finally got this working fine, but when I started building a tilemap that is bigger than 1 chunk, I encountered this weird problem:

I seriously can't figure this one out. Except the fact the colliders are all messed up, I have no idea what's wrong, or what's going on.

If you would be so kind as to help me with this, here's the code:

Thank you!

Haha thanks! That's so ridiculously obvious, I dont know why i didnt think of that myself!
Thank you

Support / TileMapColliderBuilder2D creates an extra edgecollider point/vertex

« on: January 27, 2015, 09:37:16 am »

I've converted the TileMapColliderBuilder2D to build polygoncollider2ds instead of edgecollider2ds, but now each collider now has an extra point. I understand that this was required for edge (to create the last "wall" and close the collider), but now that I have poly, they automatically create the last wall.

Does anyone know how I can fix this right off the bat?

I don't understand all of the TileMapColliderBuilder2D code, especially not the part with making "verts" and "indices," so any hints as to where to look / what to google so that I can figure it out myself works too.

I attached some example screenshots below.

Thanks, I already found that, but last time I checked his code made box colliders, and it wasn't very effective. No problem though, I already made polygon colliders; I just replaced EdgeCollider2D with PolygonCollider2D in all the files

There's some things I have to tweak to make it perfect though; tk2d creates an extra collider point for each path, and the polygon is inverted (points in wrong direction. But this isn't really a problem, polynav has a "invert polygon" feature)
I also have to add the polynav obstacle script to all chunks.
And lastly make sure all this works when I edit tiles and build.

I haven't had time to start diving into the code and fixing this yet, so if you got any tips I'd appreciate it

Support / PolyNav with TileMap

« on: January 17, 2015, 02:53:28 pm »

Hey, I'm wondering how I can use polynav with 2d toolkit's TileMap

Polynav is a simple 2D pathfinding solution that uses polygon colliders/box colliders on obstacles.
http://forum.unity3d.com/threads/poly-nav-pathfinding-for-unity2d.224962/

I'm wondering how I can make my tiles obstacles with polynav.
Each "obstacle" object needs to have a BoxCollider2D or PolygonCollider2D, and a "PolyNavObstacle" script.

My tiles are all squared, and they are going to be changed/deleted ingame.
I was thinking I need to find the edges of all "islands" so to speak, and make seperate polygoncollider2ds from them.
Note: Using prefab tiles would create too many gameobjects.

How can I achieve this? It's been bugging me for a while and I can't figure it out.
I'm sorry if this was messy and hard to understand. I've never been good at explaining things :/
Any thoughts at all would be appreciated.
Thank you

EDIT: I'll be trying to modify the 2d toolkit code to use polygon colliders instead of edgecolliders. Not sure how yet, but I'll try.
