If you try and access a private variable in a different class, we have this error:
ReferenceError: Error #1069: Property walkable not found on be.dauntless.astar.BasicTile and there is no default value.
I spent several minutes trying to debug my code to find out what is wrong because the error message is vague. I'm probably not the only one with this problem.
Could we change it to:
ReferenceError: Error #X: Property walkable found in be.dauntless.astar.BasicTile is being accessed out of permissable class.(private or protected)
