The Rect Transforms
The idea for the
Rect Transforms
started back in Unity 4.3 timescales with the
introduction of the new
Sprite
system, they were exposed through the sprite editor
when you were editing spritesheets, where you had a rectangular area to identify the
area on the spritesheet where your sprite texture would come from. This was then
used as the basis for drawing all sprites, you just didn't get to see it.
The Rect Tool
Seeing the need for more control over how sprites were drawn in the scene gave
birth to a new manipulation control in the Unity editor called the Rect Tool, which
took its rightful place in the main toolbar as shown here:
In its default mode, this tool allows visual scaling of a sprite as you can see here:
If you cannot see the blue control points, you likely need to scroll the
view in. At low zoom levels the controls are not displayed around
sprites/objects.
You get the four control points (one in each corner) to scale the sprite in or out from
that point and the central circle that forms the current pivot point.
Note: If you hold down the
shift
modifier while moving any of the
corner control points, it will scale the sprite uniformly, maintaining the
aspect ratio of the sprite (equally on each side)
This tool in effect, was built to manage sprites introduced into a scene.
