NullPointerException when using the tilemap editor?
« on: September 04, 2013, 04:57:52 am »
I followed the guide here for version 2.10.
http://www.unikronsoftware.com/2dtoolkit/docs/2.10/tilemap/tutorial.html

The only things I did different, was using my own sprite collection and using a pixels per meter of 1 for my camera and sprite collection.

I get two different errors in the console and the painter doesn't work.

Seems like starting over from scratch solves the problem, and deleting the tilemap. But I would hate for this to happen again and lose a lot of work because of it. Hopefully the stack trace helps track down the bug.

It looks like the brush is broken there - not sure how it could have happened. Were you modifying (adding and removing things) the sprite collection when this happened? I've not seen this one before.

There are ways to simply reset this without causing any issues or losing work - you can open up the tilemap data object and remove the saved brush data in there if this was caused by the brush.
