How to place a button at the bottom?

how do you get a button to go to the bottom without placing anything else

If you’re justing adding a Button to the Screen, you could set the Screen’s AlignVertical property to bottom. Depending on the complexity of your UI this may or may not work.

and I also cant get a ball to appear

The Ball component must be placed on a Canvas, so if you haven’t already added a Canvas to your screen you’ll need to do that first.

but how do you make that ball bounce

Hi @Michael_Braun,

There’s also a free book to learn App Inventor online here.


can you please give me a tutorial to make the ball go by its self all the time

If you read the tutorial @ewpatton mentioned, you can come up with a perpetual moving ball by not decreasing its speed over time.
If I give a ball a speed of 2, it will always have that speed even after bouncing.

but how do you get it to start going by itself

and is the time for the clock in seconds or miliseconds

When you set the speed it will start moving. You can do it with a button click event, or any event you want, even in the Screen1 Initialize event.

The clock works with milliseconds.
