Per unit movement and zoom
It is generally proportional to the position or obtained by real-valued, and therefore when moving a tool or game object scale, in most cases can not be exactly a certain value,
At this point in Windows, hold down the Ctri key (Mac system, hold down the Command key) while moving or zooming game objects, moving is to be captured per 1 unit, scaling is 0.1 per unit is captured

unity having four coordinates
The world coordinate system
Scene absolute coordinate in 3D space, in this coordinate system, the game is not affected by the object hierarchical structure but rather a scene from the original coordinates to represent
