Our turtle can do 3 types of moves, (1) it can go forwards and backwards, (2) it can turn left and right and (3) it can go directly to a position on the screen.

This could simply mean two things: you could have made a mistake while copying the commands, or you should still set the correct language for the &logo; commands (you can do that by choosing <menuchoice -><guimenu ->Settings</guimenu -><guimenuitem ->Configure &kturtle;...</guimenuitem -></menuchoice ->, in the <guilabel ->Language</guilabel -> section).</para> -</listitem> -</orderedlist> - -<para ->You will likely understand that <userinput ->forward 90</userinput -> commanded the turtle to move forward leaving a line, and that <userinput ->turnleft 90</userinput -> commanded the turtle to turn 90 <glossterm linkend="degrees" ->degrees</glossterm -> to the left.</para> - -<para ->Please see the following links to the reference manual for a complete explanation of the new commands: <userinput ->forward</userinput ->, <userinput ->backward</userinput ->, <userinput ->turnleft</userinput ->, and <userinput ->turnright</userinput ->.</para> -</sect2> - -<sect2 id="more-examples"> -<title ->More examples</title> -<para ->The first example was very simple, so let us go on!</para> - -<para> -<!--translators: if it's not already there, you can copy/paste the translated code below and save it in arrow.logo in your examples folder: tde-i18n/language-code/data/tdeedu/kturtle/ --> -<screen ->canvassize 200,200 -canvascolour 0,0,0 -pencolour 255,0,0 -penwidth 5 -clear - -go 20,20 -direction 135 - -forward 200 -turnleft 135 -forward 100 -turnleft 135 -forward 141 -turnleft 135 -forward 100 -turnleft 45 - -go 40, 100 -</screen> -Again you can type or copy-paste the code to the code editor or open the <filename ->arrow.logo</filename -> file in the <guimenu ->Open examples</guimenu -> folder and execute it (using <link linkend="file-execute" -><menuchoice -><guimenu ->File</guimenu -><guimenuitem ->Execute Commands</guimenuitem -></menuchoice -></link ->) to see the result.

Here a short explanation of all the new commands:</para> - -<para -><userinput ->canvassize 200,200</userinput -> sets the canvas width and height to 200 <glossterm linkend="pixels" ->pixels</glossterm ->. The width and the height are equal, so the canvas will be a square.</para> - -<para -><userinput ->canvascolour 0,0,0</userinput -> makes the canvas black. <userinput ->0,0,0</userinput -> is an <glossterm linkend="rgb" ->RGB-combination</glossterm -> where all values are set to <userinput ->0</userinput ->, which results in black.</para> - -<para -><userinput ->pencolor 255,0,0</userinput -> sets the color of the pen to red. <userinput ->255,0,0</userinput -> is an <glossterm linkend="rgb" ->RGB-combination</glossterm -> where only the red value is set to <userinput ->255</userinput -> (fully on) while the others (green and blue) are set to <userinput ->0</userinput -> (fully off). This results in a bright shade of red.</para> - -<para -><userinput ->penwidth 5</userinput -> sets the width (the size) of the pen to <userinput ->5</userinput -> <glossterm linkend="pixels" ->pixels</glossterm ->. From now on every line the turtle draw will have a thickness of <userinput ->5</userinput ->, until we change the <userinput ->penwidth</userinput -> to something else.</para> - -<para -><userinput ->clear</userinput -> clear the canvas, that is all it does.</para> - -<para -><userinput ->go 20,20</userinput -> commands the turtle to go to a certain place on the canvas. Counted from the upper left corner, this place is 20 <glossterm linkend="pixels" ->pixels</glossterm -> across from the left, and 20 <glossterm linkend="pixels" ->pixels</glossterm -> down from the top of the canvas. Note that using the <userinput ->go</userinput -> command the turtle will not draw a line.</para> - -<para -><userinput ->direction 135</userinput -> set the turtle's direction. The <userinput ->turnleft</userinput -> and <userinput ->turnright</userinput -> commands change the turtle's angle starting from its current direction. The <userinput ->direction</userinput -> command changes the turtle's angle from zero, and thus is not relative to the turtle previous direction.</para> - -<para ->After the <userinput ->direction</userinput -> command a lot of <userinput ->forward</userinput -> and <userinput ->turnleft</userinput -> commands follow. These command do the actual drawing.</para> - -<para ->At last another <userinput ->go</userinput -> command is used to move the turtle aside.</para> - -<para ->Make sure you follow the links to the reference.
