PaintPop (Part 2)

The Designer

The Block Editor

The Emulator

In part 2 of PaintPop, I learned how to make Big dots and Small dots. I had to define a global variable named small whose value was the number 2. Similar to small, a global variable big whose value was 8 was also defined. Then, a global variable dotsize was defined and I gave it an initial value of 2. In this tutorial, I learned that a global ... block produces the value of a variable while a set global ... block sets the variable to a new value.

There was a minor difficulty that occurred-the Android phone and the Designer was not showing the same thing even though both of them were connected to each other. That’s why, I had to close the Android phone, the Block Editor, and reopen everything. Finally, it worked and this whole process took only 30 minutes. In addition, I thought PaintPop Part 2 will be twice as hard as PaintPop Part 1, but I’m so glad that I was proven wrong. Therefore, PaintPop Part 2 is very simple, exciting and easy to create.

PaintPop (Part 1)

Creating the PaintPop App was very enjoyable and LOTS OF FUN! I did not have any difficulties at all. All I had to do is follow the simple and straightforward instructions from https://joners-inventor.appspot.com/learn/tutorials/paintpot/paintpot-part1.html, and my PaintPop was ready! Here, I got introduced to Canvas component for drawing, controlling screen layout with Arrangement components, event handlers that take arguments, and variables. This took me about 35 minutes and it was totally worth the time!

Introduction to Paint Pop

The PaintPot tutorial introduces the Canvas component for creating simple two-dimensional graphics. It will let you build an app that lets you draw on the phone screen in different colors!

With the PaintPot app, you can:

-Dip your finger into a virtual paint pot to draw in that color

-Drag your finger along the screen to draw a line

-Poke the screen to make dots.

-Use the button at the bottom to wipe the screen clean.

-Include an image as a drawing background.
