Some tile related questions

[ragnarok]

Hello Everybody,

 

I'm making a rogue-like with random tile-based levels.

 

For debgging-reasons:

-Is there an easy way, to anchor a text over a tile?

-Is it possible to make tiles click-able (if not, I need to make something with "tilemap.getTileWorldXY" and an mouse-input-Callback I guess)?

 

For experimenting with the Tile-Artwork:

 

Is it possible to exchange the tile-artwork for a map without  restarting the map? For example I want to exchange "woods.png" for "frozen_woods.png".

 

I guess I could add another layer, and make the (otherwise identical) layers visible depending on what I need, but I shy away from grabbing some megabyte of memory, "just in case".
