In this add-on, you'll program a weather feature for your project.

To start, add or draw a new sprite that will fall from the sky.

This example adds a snowflake, but you can add anything you like.

Make the sprite fit properly on the stage.

Next, program the sprite to fall from the sky.

Add a go to X Y block, to the script editor.

Then, drag out a pick random block.

To make the sprite start from a random spot at the top of the screen, put the pick random block inside the X value of the go to X Y block.

Type -240 and +240 in the value spaces in the pick random block to represent the far right and far left edges of the stage.

In the Y value, type in 180, which is the top of the stage.

Test it out.

To make the object fall, add a change Y block.

And enter a negative value.

The object should fall until it reaches the bottom of the stage, so add a repeat until loop around the change Y block.

Add a less than operator in the condition field.

Put a Y position block from the motion menu on the left side.

And enter a Y value on the right side, in a spot close to the bottom of the stage, like -170.

Test it out.

Looks great.

Now, add more snowflakes by cloning this sprite.

Add a one flag clicked event, then a forever loop.

And put create clone of myself, and wait blocks inside it.

Tinker with the value in the wait block to make the sprite fall more or less frequently.

Then, add a when I start as a clone block to the top of the go to X Y block.

Test it out.

Cool, the sprites fall in a flurry.

To delete the clones when they reach the ground, add a delete this clone block under the repeat until block.

Feel free to add a wait block before the delete this clone block to delay the sprite from disappearing.

You could also add clouds to cover the sprite's starting point.

To make it look like it's storming.

Consider adding a go back layers block, a set size block, and pick random blocks to make this look even more realistic.

This way, some clones fall behind the android, and some fall in front of it.

The clones also vary in size.

Now it's your turn.

Add a new sprite that will fall from the sky.

Program the sprite to fall and clone itself.

Add clouds.

Customize the sprite's falling using more pick random and wait blocks, a go back layer block, and a set size block.
