Eng:Change Size by () (block)

The Change Size by  block is a Looks block and a Stack block. The block changes its sprite's size by the specified amount. The default sprite size is 100; size values below that percentage are for shrunken sprites, and size values above it are for overlarge sprites.

Example Uses
As this block changes its sprite's size, it is used whenever a sprite's size must be changed. Some common uses are:
 * A sprite in a 3D world that must change its size as it moves along the plain
 * A growing object
 * A shrinking object
 * Changing the size of a paintbrush for painting
 * Draining a pool of water by shrinking the water sprite

Workaround
The block can be replicated with the following code:

set size to ((size) + (amount))% However, this is not exact because the main block rounds it and the math block gives exact numbers.
