If you have an older version you can continue to use it.
You can still move the whole environment on the X axis, both before and during the building, by acting on the camera position using its 2.5dTK control.
In any case, if your game requires a certain position in space, once you have completed your work and saved it, you can still manually move the entire environment where you need it.
***
Once completed, the environment can be moved anywhere in 3d space on the X and Y axes. Editing will still be possible but keep in mind that editing after moving is an experimental feature. If you encounter any problems please notify us.
