Well, just bought.
The first thing is that i had to erase all the physics behaviours on the project and then i added the Box2D+ behaviour to the TileMap Family and i got this error:
Also tried to open a new blank project and still the same error message. Nor works on tilemaps for object or family. Tried to change for static, dyanmic and other values and same problem.
Tried with sprites and works perfect.
EDIT: Found the bug, with tilemaps with 1x1 pixels to 7x7 pixels not works, for 8x8 pixel size to up works(I mean the Tile Width/height). Can you fix it?
EDIT2: Tried with my project and only works with tile width/height to 64x64 , mmm i dont know what is happening :S . Seems only works when there is no tiles on tilemap. In the moment you set at least one tile then the error appears.
Also is possible that you include the .capx of the demo with all the tests? The one with polygons, comparision, drawing objects,etc... ?
