Change () Effect by ()
Category	Looks
Type	Stack

The Change () Effect by () block is a Looks block and a Stack block. The block changes the specified effect on its sprite by the specified amount. There are seven different effects to choose from: color, fisheye, whirl, pixelate, mosaic, brightness and ghost.

Example Uses

As this block changes an effect, it is used whenever an effect's value must be changed - some common uses are:

• Changing the color of a graffiti can with the color effect
• Using the fisheye effect to make a sprite look like it is in water
• Whirling sprites with the whirl effect
• Pixelating sprites with the pixelate effect
• Creating the illusion of multiple sprites with the mosaic effect
• Creating different brightness levels with the brightness effect
• Making creatures transparent with the ghost effect
• Making a sprite change color (in the project) with the color effect

There can be multiple effects on a sprite at once - effects can be combined to produce even more brilliant effects.

Workaround

Main article: List of Block Workarounds

If a variable held the strength of the effect, the Change () Effect by () block could be replicated with the following code:

set [wanted v] effect to ((current amount) + (increase))

However, while this is not possible in current versions of Scratch, it is in some Scratch Modifications.
