What happens when you change the opacity of a sprite in CodeHS?

Changing the opacity of a sprite in CodeHS results in a gradual adjustment of the sprite's visibility on the canvas. When the opacity is decreased, the sprite becomes less visible, allowing the background or other elements of the canvas to be seen through it. At an opacity value of 0, the sprite becomes fully transparent and is not visible at all. This feature is particularly useful for creating effects like fading in or out, which can enhance the visual quality of animations and games.

Other options present scenarios that do not accurately represent how opacity affects a sprite. For instance, changing the opacity does not interfere with the sprite's colors or permanently alter them. It also does not impact the sprite's speed in any way, nor does it cause the sprite to disappear completely from the game at all times; the sprite simply becomes transparent when its opacity is adjusted to zero.
