Title: Tilemaps are amazing, but how do I dynamically create them?
Post by: roaet on August 31, 2013, 07:01:05 am

I really like tilemaps but I have level data stored externally and would like to generate them runtime. Is that possible? Thanks for the support. Love your product!

Hi,

There isn't an "official" way to create tilemaps at runtime, as a lot of the code is simply stored in editor code to reduce runtime bloat. Easy option - create a HUGE tilemap (max size is fine), but keep it empty. Then you can tweak as necessary at runtime - empty tilemaps don't really take up that much memory (close to negligible).

Or do the above, create a prefab and instantiate at runtime. The tilemap requires the data / editor data objects, which are a pain to generate at runtime.

You could use

Code: [Select]

tileMap.Layers[i].SetTile(x, y, id)to set the tiles at runtime. You can get the id via

Code: [Select]

tileMap.SpriteCollectionInst.GetSpriteIdByName("YOURSPRITENAME")
At the end, use

Code: [Select]

tileMap.Build()to build the actual tilemap.

For anyone who is interested, I posted a comprehensive guide to dynamically creating a TileMap here: http://praveenangyan.com/2014/03/02/dynamically-displaying-a-level-with-tk2dtilemap-in-2d-toolkit-for-unity/ (http://praveenangyan.com/2014/03/02/dynamically-displaying-a-level-with-tk2dtilemap-in-2d-toolkit-for-unity/)
