In this add-on, you will program confetti, snow, leaves, hearts, or stars to create a fun atmosphere for your animation.
You might use confetti to celebrate a birthday, snow for wintertime, leaves for autumn, hearts for Valentine's day, or stars for another special day.
To start, program the "confetti" sprite to create clones when the flag is clicked.
Then, add a "when flag clicked" block, a forever loop, then a "create clone," and "wait" block.
If you'd like, make the falling sprite appear semi-transparent.
Add a "set effect" block.
Select "ghost" from the dropdown, and type in 50.
Next, program the clone to start at a random spot at the top of the stage.
Add a "when I start as clone" block, a “show” block, and a "go to xy" block.
The top of the stage is y equals 180, so set y equal to 180.
Set the x to a random value by adding a "pick random" block.
Type in -240 to 240 in the values.
Click this block stack to test.
Next, program the clones to glide to a random point near the bottom of the stage, then delete.
Add a "glide" block and put "pick random" blocks in the x and y values.
In the x side, type in -240 and 240, which are the edges of the stage.
In the y side, type in negative 100 and negative 180.
Negative 180 is the bottom of the stage.
At the bottom of the code stack, add a "delete this clone" block.
Click the “when flag clicked” block stack to test.
This moves really fast.
Put a larger number in the “glide” block to make the sprite glide for longer.
This example uses 6 seconds.
Click the flag to test again.
Okay, this looks better, but it’s not very exciting.
It would be more fun if the falling sprite changed colors.
Add a "set effect" block under the "go to" block.
Add a "pick random" block, and type in 0 and 200.
Much better, but it might look more interesting if the clones were different sizes.
Add a "set size" block.
Add another "pick random" block, and choose a size range.
This example uses 50% to 125%.
Test this.
Cool.
Next, program the falling sprite to turn as it falls.
Add a "when I start as a clone" block and a forever loop.
Inside the loop, add a "turn" block.
Add a "pick random" block, and type values into it.
This example uses 0 and 180.
Click to test.
That looks a little crazy.
To fix this, add a "wait" block under the "turn" block, and adjust the value.
This example uses 0.1 seconds.
Click to test again.
Awesome.
Finally, you might have noticed the original falling object sprite is not moving -- only the clones are.
To fix this, add a "hide" block under the "when flag clicked" block.
Click the flag to test.
Now, the clones show but the sprite itself is hidden.
This effect really makes your animation feel more fun and playful.
Now, it's your turn.
Program the falling sprite to forever create clones of itself, and set its ghost effect.
Make the sprite start at a random point at the top of the stage, then fall to a random point near the bottom of the stage.
Program the sprite to set to a random color and size.
Program the sprite to continuously turn in a random direction as it falls.
