Visual Cue	Narration
00.01	Hello everybody. Welcome to this tutorial on Introduction to KTurtle.
00.07	In this tutorial I will introduce you to the basics of getting started with KTurtle.
00.14	In this tutorial, we will learn about
00.17	KTurtle Window
00.19	Editor
00.20	Canvas
00.21	Menu Bar
00.22	Toolbar
00.24	We will also learn about,
00.26	Moving the Turtle
00.28	Drawing lines and changing directions.
00.32	Draw a triangle
00.34	To record this tutorial I am using Ubuntu Linux OS version. 12.04. KTurtle version. 0.8.1 beta.
00.47	What is KTurtle?
00.49	KTurtle is a free tool to learn basic programming.
00.53	It is useful for computer aided interactive learning
00.59	KTurtle is available for download at http://edu.kde.org/kturtle/
01.12	KTurtle makes programming easy and accessible .
01.18	Helps teach kids basics of mathematics.
01.22	Translates commands to speaking language of the programmer
01.27	Translates commands into visuals.
01.31	We can install KTurtle using Synaptic Package Manager .
01.36	for more information on Synaptic Package Manager
01.40	please refer to Ubuntu Linux tutorials on our websitehttp://spoken-tutorial.org
01.46	Let's open a new KTurtle Application.
01.50	Click on Dash home.
01.52	In the Search bar, type KTurtle.
01.55	And Click on the KTurtle icon.
01.59	A typical KTurtle window looks like this.
02.02	This is the Menubar.
02.04	In the menu bar on the top,
02.06	You will find menu items
02.08	File, Edit, Canvas, Run, Tools, Settings and help options
02.17	In the tool bar, you can reach for most of the actions used.
02.23	Editor is on the left, where you can type the TurtleScript commands.
02.30	Most of the functions of the editor can be found in the File and Edit menus.
02.37	There are several ways to enter the code in the editor.
02.42	Easiest way is to use an example.
02.46	Go to File menu > select Examples
02.50	Here I will select a flower
02.53	Code of the selected example opens in the editor.
02.58	Click on the Run button from Menu bar or Tool bar to run the code.
03.04	Another way is to directly type your own code in the editor
03.10	or copy/paste some code in the editor
03.13	for example: from other KTurtle files
03.18	Canvas is on the right, where Turtle makes your drawings.
03.24	Turtle draws accordingly to the commands it gets from the editor on the canvas
03.32	Run option on the tool bar starts execution of the commands in the editor.
03.39	It presents a list of execution speeds.
03.43	Full speed(No highlighting and inspector),
03.46	Full speed,
03.48	Slow,
03.49	Slower,
03.51	Slowest and
03.52	Step-by-Step
03.55	Abort and pause options allow you to stop and pause the executions respectively.
04.03	Let's now Run this code .
04.06	Turtle draws a flower on the canvas.
04.11	When you open a new KTurtle application.
04.15	Turtle is in the middle of the canvas by default.
04.19	Let's now move the Turtle.
04.22	Turtle can do three types of moves:
04.25	It can move forwards. It can move backwards
04.29	It can turn left or right.
04.32	It can also jump directly to a position on the screen.
04.38	Let me zoom into the program text it may possibly be a little blurred.
04.44	Let us go through a simple example.
04.48	In your editor, type the following commands:
04.52	reset
04.55	forward 100
04.58	turnright 120
05.02	forward 100
05.07	turnright 120
05.11	forward 100
05.15	turnright 120
05.18	Note that the color of the code changes as we type .
05.23	This feature is called highlighting.
05.26	Different types of commands are highlighted differently,
05.31	which makes it easier to read large blocks of code.
05.36	I will explain the code now.
05.38	reset command sets Turtle to default position.
05.42	forward 100 commands Turtle to move forward by 100 pixels.
05.49	turnright 120 commands Turtle to turn, 120 degrees anti-clockwise.
05.56	Note that these two commands are repeated thrice to draw a triangle.
06.03	Let's now execute the code.
06.06	I will choose Slow step so that we understand what commands are being executed.
06.16	Here the triangle is drawn.
06.19	Let's look at another example and also learn how to beautify our canvas.
06.26	Let's draw a triangle using repeat command.
06.30	I will clear the current program.
06.33	Let me zoom into the program text to have a clear view.
06.38	Type the following commands into your editor:
06.41	reset
06.44	canvassize space 200,200
06.51	canvascolor space 0,255,0
07.00	pencolor space 0,0,255
07.08	penwidth space 2
07.12	repeat space 3 within curly braces {
07.19	forward 100
07.23	turnleft 120 }
07.27	Let me now explain the code.
07.30	reset command sets Turtle to its default position.
07.34	canvassize 200,200 sets the canvas width and height to 200 pixels.
07.42	canvascolor 0,255,0 makes the canvas green.
07.48	0,255,0 is a RGB Combination where only the green value is set to 255 and the others are set to 0.
08.03	This makes the canvas green in color.
08.07	pencolor 0,0,255 sets the color of pen to blue.
08.14	RGB combination where blue value is set to 255.
08.20	penwidth 2 sets the width of the pen to 2 pixels.
08.27	repeat command is followed by a number and a list of commands within curly brackets.
08.33	This repeats the commands within the curly brackets the specified number of times.
08.39	Here the commands forward 100 and turnleft 120 are within curly brackets.
08.47-	repeat command is followed by the number 3, because a triangle has 3 sides.
08.54	These commands are run 3 times in a loop.
08.59	3 sides of the triangle are drawn.
09.02	Let's Run the code now
09.05	I will select slow option for execution of the program.
09.09	The canvas color becomes green and the Turtle draws a triangle.
09.20	Let's now save the file.
09.23	Select File menu > Save As
09.27	Save As dialog box opens.
09.30	I will select Document folder for saving the file.
09.34	I will type the file name as Triangle and click on Save button.
09.41	Notice that the name of the file appears in the top panel and it is saved as a dot turtle file like all Turtle files.
09.53	With this we come to the end of this tutorial.
09.57	Let's summarize.
