  Introduction

  When you click on the color input, you can use the color picker tool to get the exact color value at any point you click.

   
  You can actually do this using a block, which would allow your program to “scan” the stage automatically.

   
   

  Description

  To read the color value at any position on the stage, you can use this block:

  X and Y Positions

  The first 2 inputs are the X and Y positions of the point you would like to read. For example, if you want to know the color at the center point of the stage, then you should input 0 for both inputs.

   
   

  Output Variables

  Each type of color is actually represented by 4 numbers: color, brightness, saturation and transparency. Before you use this block, you need to first define 4 variables, and then select them in the 4 dropdowns of this block.

  After you run this block, these 4 variables will contain the 4 numbers that represent a color.

   
   

  Demo

  As shown, we first manually read the brown color at the center of the stage using the color picker tool, which gives us these values: color = 9, saturation = 81, brightness = 60, transparency = 0.

  Next, we use the “read color” block, which will store the same 4 numbers into the 4 variables: color = 9, saturation = 81, brightness = 60, transparency = 0.

  Description

  When an object is controlled by the physics engine, you can set limits on how it rotates using this block:

  Let’s go through the 5 input parameters:

   
   

  Speed Limit

  The first input is the maximum speed the object is allowed to rotate in:

  If the object is rotating at a slower speed, then it will not be affected by this limit; If the object is rotating at a faster speed, then its speed will be reduced to this value.

  In other words, you can use this block to make sure an object does not rotate too fast.

  If you do not want to set a speed limit, you can leave this input empty or specify a very large number.

   
   

  Allowed Rotation Axes

  The next 3 inputs are used to specify whether the object is allowed to rotate around each of the 3 axes. For example, if we set X to “No”, then the object will not rotate around the X axis.

   
   

  Object Name

  If you leave the name input empty, the currently selected sprite object will be given the speed limit. If you input an object’s name, then that object will be given the speed limit.

   
   

  Demo

  In this program, we place a box on a plane, then apply an impulse to push it.

  When there is no limit, the box will rotate around both the X-axis and Y-axis.

  If we set a rotation speed limit of 10, the box will rotate much slower.

  If we set the X direction to “No”, then the box would only rotate around the Y-axis.

  If we set the Y direction to “No” as well, then the box would not rotate at all.

  Prerequisite The For-Loop Block The Repeat Block The Repeat Until Block The Forever Block

   

  What are Loops?

  A “loop” is a block for playing other blocks repeatedly. Below are some loop blocks you can use on the CreatiCode playground;

  
   

  What are Nested Loops?

  When you put one loop inside another loop, it becomes a “nested loop”. You can even have a third loop inside the inner loop.

  
   

  How Nested Loops Work?

  When you run a program with a nested loop, the inner (child) loop will work like a normal loop. However, because of the outer (parent) loop, the inner loop itself will be repeated.

  Here is a step-by-step example:

  Step 1: The main loop is played.

  
   

  Step 2: The Nested loop is started.

  
   

  Step 3: The blocks inside the nested loop are played until the condition of the nested loop is completed.

  
   

  Step 4: The blocks after the nested loop are played (if there are any).

  
   

  Step 5: The main loop is restarted.

  Note: All of the above 5 steps keep repeating until the condition of the main loop is completed.

  For example, as shown below, “repeat until ” is the nested loop, which keeps the monkey moving until it touches the edge of the stage. And “repeat (5)” is the main loop which repeats the nested loop 5 times.

  
   

  Use of Nested Loops

  We use Nested loops when we want to repeat multiple blocks at the same time, until multiple conditions are completed.

  For example, as shown below, nested loops are used to make the monkey move and eat bananas at the same time.

  Introduction

  In the CreatiCode playground, approved teacher users can view and manage student users, such as reviewing their projects directly.

   
   

  Teacher Account Setup Application

  To act as a teacher user to other users, the teacher account needs to be approved and configured. Please send an email titled “Teacher Account Setup” to info@mail.com, and provide the following information:

  Your Full Name School/Organization Name Your email: The email you will use to log in as the teacher user. Normally it should be an official email from your school or organization, such as “yourname@bestschool.org”, otherwise please explain why you can’t use an official email. Teacher Status Verification: this can be the link to a page on your school/organization’s official website that shows your name or email, or some other official document that verifies you are a teacher at the school Student List: the list of student emails that you wish to set as your student users, such as a CSV file or a google sprite sheet. These emails need to be the emails that these students use to log into the CreatiCode playground. You can also specify the class name for each student. Note that the student emails should also come from the same domain as your teacher email, such as “xxxx@bestschool.org”. This serves as an additional safeguard to protect student information.

  Once we have verified your teacher status, your account will be configured to be the teacher to these students

   
   

  Open the “My Students” Page

  As a teacher user, you can visit the “My Stuff” page, and select the “My Students” tab on the bottom left. All your students will be listed on this page:

   
   

  The “My Students” Table

  The table contains 5 columns:

  Number: a sequence number Username: the user name of each student Class: the class that student belongs to. You can use this field to organize students based on their classes. Email: the email for that student Premium: whether this student has premium privilege. if your teacher account is premium, then you can click on the “No” button to assign a premium seat to that student, or click on the “Yes” button to reclaim that seat from that student.

   
   

  Controls at the Top

  Above the student table, there are a few controls you can use:

  Search Box: You can use the student name or class name to filter the student table below.

  Sort By: You can sort the students from A to Z or from Z to A Premium Seat Count: You can check how many premium seats are available for you to assign to students, and also the total number of premium seats your account has.

   
   

  View One Student’s Projects

  You can click on the user name of any student in the table to open that student’s profile page, which includes a few project lists of that student. You can click “View All” to see all the projects on any of these lists.
