Firstly, you go to the My Stuff button.
Then, you click on the +New Project button.
Now, you choose a sprite. If you don’t know, follow my tutorial on “How to add a sprite“.
Next, you go to the when flag clicked button, and drag it.
Then, you go to the looks section, and get the hid button. You then drag it, underneath the when flag clicked button.
Then, you go to the control section. You get the wait 1 seconds button and drag it underneath the hide button.
If you want to wait more than 1 second, click on the 1, and type another number.
You then go to the looks section, and get the button that says show. It is above the hide button.
If you want to keep it going, you go to event section, and get the forever button. You put it under the when flag clicked button, and it will stretch by itself all the way down.
