Welcome to the tutorial Introduction to KTurtle.

In this tutorial I will introduce you to the basics of getting started with KTurtle.

|-

It is a free programming software

and is available at [http://edu.kde.org/kturtle/ http://edu.kde.org/kturtle/] for download.

|-

* as it is interactive, and it makes programming easy and accessible.<br/>

* It helps teach kids the basics of maths, geometry and programming.<br/>

* It translates commands into the speaking language of the programmer.

* I am using the Linux operating system Edubuntu, Version 11.04
* and KTurtle Version 0.8.1 Beta

|-
| style="border-top:none;border-bottom:0.002cm solid #000000;border-left:0.002cm solid #000000;border-right:none;padding:0.097cm;"| <center>Switch to Desktop to Open KTurtle</center>

and click on the '''KTurtle''' Application.

If you have not installed KTurtle,

go to '''System''' > '''Administration >''' '''Synaptic Package Manager''' to install '''KTurtle'''.

Search for the package '''kturtle, mark it for installation and click Apply.'''

To know more about how to use '''Synaptic Package Manager, '''you can refer the following link –

[http://spoken-tutorial.org/Linux2_Ubuntu_Synaptic_Package_Manager_English http://spoken-tutorial.org/Linux2_Ubuntu_Synaptic_Package_Manager_English]

Another way to open KTurtle in Ubuntu 11.04

is by going to '''Applications > Accessories > Terminal'''

and at the prompt type “kturtle” and hit 'Enter' this will open the application.

In this tutorial, I will briefly explain

'''the editor,''' '''the canvas, the menubar, and the toolbar '''

and also the input commands.

|-
| style="border-top:none;border-bottom:0.002cm solid #000000;border-left:0.002cm solid #000000;border-right:none;padding:0.097cm;"| <center>Switch to KTurtle Application</center>

It has –

in the '''menu bar '''on the top''', '''you will find the '''file, edit, canvas, run, tools, settings '''and '''help '''options

in the '''tool bar, '''you can reach for the most used actions.

the '''editor '''is on the left, where you type the TurtleScript commands.

most of the functions of the editor can be found in the '''file '''and '''edit '''menus.

there are several ways to enter the code in the editor.

Easiest way is to use an example.

Go to the '''file '''menu > '''examples''' and select an example.

The chosen example will be opened in the editor.

You can select '''run '''from the menu bar or the tool bar to run the code.

Another way is to directly type your own code

or copy/paste some code in the editor

(for example, from other kturtle files)

|-
| style="border-top:none;border-bottom:0.002cm solid #000000;border-left:0.002cm solid #000000;border-right:none;padding:0.097cm;"|

The turtle draws accordingly to the commands it gets from the editor.

|-

It presents a list of possible execution speeds.

'''Full speed, slow, slower, slowest and step-by-Step'''

the '''abort '''and the '''pause '''options allow you to stop and pause the executions respectively

|-
| style="border-top:none;border-bottom:0.002cm solid #000000;border-left:0.002cm solid #000000;border-right:none;padding:0.097cm;"| <center>Switch back to Slide 4</center>

'''moving the turtle'''

'''how to draw lines and '''

'''changing directions'''.

|-
| style="border-top:none;border-bottom:0.002cm solid #000000;border-left:0.002cm solid #000000;border-right:none;padding:0.097cm;"| <center>KTurtle Window</center>

<center>Using the Tool</center>
| style="border-top:none;border-bottom:0.002cm solid #000000;border-left:0.002cm solid #000000;border-right:0.002cm solid #000000;padding:0.097cm;"| When you open '''KTurtle, '''

the turtle is in the middle of the canvas by default.

Let us start by getting the turtle to move.

The '''turtle '''can do three types of moves:

it can move forwards and backwards

it can turn left and right; and

it can go (or jump) directly to a position on the screen.

Let us go through a simple example.

In your '''editor''', type the following commands:

'''reset'''

'''forward 100'''

'''turnleft 120'''

'''forward 100'''

'''turnleft 120'''

'''forward 100'''

'''turnleft 120'''

Also, note that the color of the code changes as we type it.

This feature is called the '''''highlighting –'''''

different types of commands are highlighted differently,

which makes it easier to read large blocks of code.

I am now clicking on '''run '''to execute the code

''I will choose the '''Slower '''option so that we understand what commands are being executed.''

The '''reset '''command sets the turtle to the '''default position.'''

The '''forward 100 '''command instructs the turtle to move forward by 100 pixels.

The '''turnleft 120 '''instructs the turtle to turn to the left ,anti-clockwise by 120 degrees.

'''Note that these two commands are repeated three times and a triangle is drawn.'''

Lets look at another example and also how to beautify our canvas:

'''We will now draw a triangle using a repeat command'''

'''''A Simple Example: To draw a triangle'''''

Type the following commands in the editor:

'''reset'''

'''canvassize 200,200'''

'''canvascolor 112,179,0'''

'''pencolor 0,0,255'''

'''penwidth 2'''

'''repeat 3 {'''

'''forward 100'''

'''turnleft 120'''

'''}'''

Click on '''Run '''now.

I have selected the '''slower '''option here again to run the commands.

The '''reset '''command sets the turtle to the '''default position.'''

The '''canvassize 200,200 '''sets the canvas width and height to 200 pixels

(here width=height, so the canvas is a square).

The '''canvascolor 0,255,0 '''makes the canvas '''green. '''

0,255,0 is a '''RGB (Red-Green-Blue)-Combination '''where only the '''green '''value is set to '''255 (fully on)'''

and the others are set to '''0 (fully off) ''',

which results in the canvas being in green color.

The '''pencolor 0,0,255 '''sets the color of the pen to '''blue '''

'''('''RGB combination where black value is set to 255).

The '''penwidth 2 '''sets the the width (i.e. the size) of the pen to 3 pixels.

The '''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.

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

and the repeat command is followed by the number 3 (because a triangle has 3 sides).

These commands are run 3 times in a loop

and all the 3 sides of the triangle are drawn.

|-
| style="border-top:none;border-bottom:0.002cm solid #000000;border-left:0.002cm solid #000000;border-right:none;padding:0.097cm;"| <center>KTurtle Window -Saving and Opening a File</center>
| style="border-top:none;border-bottom:0.002cm solid #000000;border-left:0.002cm solid #000000;border-right:0.002cm solid #000000;padding:0.097cm;"| To save a file,

select menu item F'''ile > Save As . '''

I will select the '''Documents''' folder,

then the '''Kturtle '''folder within it.

I will enter the file name as '''triangle''' and click '''Save'''.

Notice that the name appears in the top panel

and it is saved as a '''.turtle''' file like all KTurtle files.

Now to open a file, go to '''File > '''Open.

Select the file to open.

|-

Here I would like you to draw a '''square'''

by using the '''commands '''which we have just learnt'''.'''

That is , '''forward, backward, turnleft, turnright and repeat'''

Also set the background color, penwidth and pencolor to a color of your choice

by changing the values in the RGB combination

as shown in the example earlier.
