Use the slider to control the wind.
Reflection I learned something new about the random block: It can output integers or floating point numbers. For example, this will select a whole number from 1 through 10: (pick random (1) to (10)) If a decimal values are used as parameters then a decimal value is returned. For example, the following will produce a number between 0.0 and 1.0: (pick random (0.0) to (1.0)) However, I also just learned that decimal numbers with a .0 are truncated to whole numbers when the projected is loaded back up. So there's a bug in Scratch. To get around this, instead of using -1.0 and 1.0 for the jitter, I set the value range to -1.1 and 1.1, which keeps the values from truncating. I also used 4.9 and 16.1 for generating the size of the snowflakes. More on the random block at the wiki: https://en.scratch-wiki.info/wiki/Pick_Random_()_to_()_(block) As for this project, the random block is used twice. First, it is used to randomly generate the size of a snowflake. Second, it is used to add jitter as it falls to the ground.
