set Scale

Set the scale factor for a sprite based on an anchor point.

sprites.create(null).setScale(1, ScaleAnchor.Middle)

You can increase or decrease a sprite from it’s current size to a new size by setting a scale value. If a sprite’s scale is set to 2, then the sprite’s new size is two times larger than it’s original size. The sprite’s size will shrink if you give a negative value. If you use -3 for the scale value, the sprite’s new size will three times smaller than it’s original size.

The anchor determines which direction the sprite will expand or shrink. If you increase the scale from the middle, the sprite will grow equally from it’s center. If you choose to scale from the bottom left, the sprite will grow toward the top right of the screen.

Parameters

• value: a number that is the scale factor for the sprite.
• anchor: an anchor point to scale the sprite from:

  • middle
  • top
  • left
  • right
  • bottom
  • top left
  • top right
  • bottom right
  • bottom left

Examples

Scale in 4 directions

Create a sprite with a square image. Make the sprite grow and shrink by 3 in each of the 4 corner directions.
