Welcome to Simple Programming App! This app has one sprite and one backdrop. Write code by adding commands to the code list. Commands usually use two lines: 1. The command 2. Its value But not always. The run mechanism takes about 0.5 seconds to go through each line, due to scratch's speed. BUTTONS Add code Adds code at the end of your code list. You can type any supported command. Delete code Deletes the line of code you choose. Replace code Replaces the line you choose with the text entered in “What is the content of this line?” Insert code Inserts text at the line you choose using the “What would you like to insert?” input. Run code Runs your code. Search the costume library Search for a word to see which costumes the sprite has with that word in their name. Search the backdrop library Search for a word to see which backdrops have that word in their name.
