Hello I want to know whether it is possible to set the coordinates of the object editor? Just like here:

Give an example how to do it?

You have to select object in World Editor and then try to move it or just click RMB. Then, the window with x, y and z axis positions will appear.

I know how to arrange the objects. I need to specify the exact location, just enter. As in the picture

Press Z in Editor or click on Position button (upper right corner near Custom button in World Editor). Since now when you select object the window which allows you to set precise position will shown.

Thanks!
