  • Menu Bar
  • Toolbar

We will also learn about,

  • Moving the Turtle
  • Drawing lines and changing directions
  • Draw a triangle
Slide Number 3

System Requirement

To record this tutorial I am using

Ubuntu Linux OS version. 12.04.

KTurtle version. 0.8.1 beta.

Slide Number 4

What is KTurtle?

What is KTurtle?

KTurtle is a free tool to learn basic programming.

It is useful for computer aided interactive learning

KTurtle is available for download at

http://edu.kde.org/kturtle/

Slide Number 5

Utilities of KTurtle

KTurtle
  • Makes programming easy and accessible .
  • Helps teach kids basics of mathematics.
  • Translates commands to speaking language of the programmer
  • Translates commands into visuals.
Slide Number 6

Install KTurtle

* We can install KTurtle using Synaptic Package Manager .
  • for more information on Synaptic Package Manager

  • please refer to Ubuntu Linux tutorials on our website

http://spoken-tutorial.org

Switch to KTurtle Application

Dash home >>In the Search bar>>

Type KTurtle Click on the KTurtle icon.

Let's open a new KTurtle Application.

Click on Dash home.

In the Search bar, type KTurtle.

And Click on the KTurtle icon.

Switch to KTurtle Application

Move the mouse over the window

A typical KTurtle window looks like this.

This is the menubar.

In the menu bar on the top,

You will find menu items

File, Edit, Canvas, Run, Tools, Settings and help options

Tool bar In the tool bar, you can reach for most of the actions used.
Editor Editor is on the left, where you can type the TurtleScript commands.

Most of the functions of the editor can be found in the File and Edit menus.

How to write code in the editor There are several ways to enter the code in the editor.

Easiest way is to use an example.

Go to File menu > select anti-clockwise

Here I will select a flower

Code of the selected example opens in the editor.

Click on Run button from menu bar or tool bar to run the code.

Another way is to directly type your own code in the editor

or copy/paste some code in the editor

for example: from other KTurtle files

Show the Canvas Canvas is on the right, where Turtle makes your drawings.

Turtle draws accordingly to the commands it gets from the editor on the canvas

Run options. Run option on the tool bar starts execution of the commands in the editor.

It presents a list of execution speeds.

Full speed(No highlighting and inspector),

Full speed,

slow,

slower,

slowest and

step-by-Step

Abort and pause options allow you to stop and pause the executions respectively.

Let's now Run this code .

Turtle draws a flower on the canvas.

Show position of Turtle

When you open a new KTurtle application.

Turtle is in the middle of the canvas by default.

Let's now move the Turtle.

Turtle can do three types of moves:

iBold textt can move forwards. it can move backwards

it can turn left or right.

it can also jump directly to a position on the screen.

Zoom text Let me zoom into the program text it may possibly be a little blurred.
Type the code in the editor

reset

forward 100

turnleft 120

forward 100

turnleft 120

forward 100

turnleft 120

Let us go through a simple example.

In your editor, type the following commands:

reset

forward 100

turnright 120

forward 100

turnright 120

forward 100

turnright 120

Highlighting Note that the color of the code changes as we type .

This feature is called the highlighting. Different types of commands are highlighted differently, which makes it easier to read large blocks of code.

I will explain the code now.
Explanation of code reset command sets Turtle to default position.

forward 100 commands Turtle to move forward by 100 pixels.

turnright 120 commands Turtle to turn, 120 degrees anti-clockwise.

Note that these two commands are repeated thrice to draw a triangle.

Run the code Let's now execute the code.

I will choose Slow step so that we understand what commands are being executed.

Here the triangle is drawn.

Let's look at another example and also learn how to beautify our canvas.

Let's draw a triangle using repeat command.

I will clear the current program.

Zoom text Let me zoom into the program text to have a clear view.
reset

canvassize 200,200 canvascolor 0,255,0 pencolor 0,0,255 penwidth 2 repeat 3 { forward 100 turnleft 120 }

Type the following commands into your editor:

reset canvassize space 200,200 canvascolor space 0,255,0 pencolor space 0,0,255 penwidth space 2 repeat space 3 within curly braces { forward 100 turnleft 120 }

Let me now explain the code.
Highlight reset reset command sets Turtle to its default position.
Highlight canvassize 200,200 canvassize 200,200 sets the canvas width and height to 200 pixels.
Highlight canvascolor 0,255,0 canvascolor 0,255,0 makes the canvas green.

0,255,0 is a RGB Combination where only green value is set to 255 and the others are set to 0. This makes the canvas in green color.

Highlight pencolor 0,0,255 pencolor 0,0,255 sets the color of pen to blue

RGB combination where blue value is set to 255.

Highlight penwidth 2 penwidth 2 sets the width of the pen to 2 pixels.
Highlight repeat repeat command is followed by a number

and a list of commands within curly brackets. This repeats the commands within the curly brackets the specified number of times.

Highlight forward 100 and turnleft 120

Here the commands forward 100 and turnleft 120 are within curly brackets.

repeat command is followed by the number 3, because a triangle has 3 sides. These commands are run 3 times in a loop. 3 sides of the triangle are drawn.

Run the program Let's now Run the code now

I will select slow option for execution of the program. The canvas color becomes green and the Turtle draws a triangle.

Save file Let's now save the file.

Select File menu > Save As . Save As dilog box opens. I will select Documents folder for saving the file. I will type the file name as triangle and click on Save button. Notice that the name of the file appears in the top panel and it is saved as a dot turtle file lilke all Turtle files.

With this we come to the end of this tutorial.

Let's summarize.
