Time	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.
09:59	In this tutorial, we have learnt about,
10:02	KTurtle's editor, canvas, menubar and toolbar
10:07	Move Turtle
10:09	Draw lines and change directions
10:13	Draw a triangle
10:15	As an assignment I would like you to draw a square. using the commands.
10:21	forward, backward, turnleft, turnright and repeat
10:26	* Set background color, penwidth and pencolor of your choice
10:32	Change values in the RGB combination
