My Internet Safety Guide I have used scratch to program a guide to internet safety using QR codes.
3
Sequences This shows how I started the sequence. You need to decide how a sequence starts. Definition: A sequence is a series of steps in a logical order. I then told my main character when to say things and when to send messages to other sprites.
4
Threads (Parallel execution) Definition: A thread is when many scripts start at the same time. I used threads to make all of my codes hide at the same time.
5
Messages (Coordination and Synchronization) Definition: Coordination and synchronization is when you make things happen at the correct time. I used messages to tell my sprites when to show and hide.
6
Variables Definition: A variable is something that changes. Variables can be used to control when things happen. First I made a variable called click. Then I made a button and put this code on it to change the variable. I then used the number in the variable to control when my messages were sent.
