Paint

In this project, we’re going to make a Paint application, where you can draw, erase, and choose different colors to paint a picture.

1) Set up stage, with a picture you want to paint, and couple of color buttons to choose from.(In this example, we choose a picture of a cat, and five different color circle buttons on the palette)

2) Create a brush sprite, make the sprite move with cursor.

3) Create a color variable to record which color has been clicked

4) Switch brush costume when the color is clicked

5) Click the brush costume to start painting on the picture.

6) Create a clear all button to clear the screen up.

7) Adding a slider variable to set the size of the brush.
