I have used Scratch, to program a guide to internet safety. This is done by using QR codes to make it more interactive and interesting for people playing it. Coding for my game

Sequences When the green flag on my game is clicked this activates all the programing and the game will play, this is the beginning of the sequence of all the coding. A sequence is a series of steps that go in logical order. Then the character explains what do and what it’s all about, this type of coding can be used to say messages on the game.

Threads I used threads so that all my QR codes would hide at the same time. A thread is where multiple Scripts start at the same time.

Coordination and synchronization When you make things happen at the correct time by sending a message. I used a message so that I could make my phone appear after my character finished speaking.

Variables Then add coding to control what you want it to do. You first make the variable. Something that can change. They can change when tings happen, it can also keep score. I have not used any variables in my game’s coding.
