Nothing is under it, the pen will make whatever line is commanded. When the peĬommand is used, movement of the turtle erases whatever is under it. If you don't want to leave a line as the pen repositions, be To set the pen to the left, use negative numbers such as: setpos [-200 This would move the pen to the right 200 pixels and forward 100 pixels. For example, pu fd 200 rt 90 fd 100 lt 90 pd.Īnother way to set the turtle to a specified screen location is to use the setpos command. To move the turtle to various places on the screen, use the pu command, followed by movement and directional commands. Note that additional colors can be generated by sliding the Top left of the LOGO screen, then clicking "screen color" and making a
Screen color is selected by clicking "set" at the Note that additional colors can be generated by sliding the three color The LOGO screen, then click "pen color," and make a color selection. You can also choose a pen color by clicking "set" at the top left of OtherĬolors are created by manipulating these three numbers. SetPC creates green, and SetPC creates blue. To the appropriate RGB (red, green, blue) values, where r, g, and b are You can also select pen sizeīy clicking "set" at the top left of the LOGO screen, then select "pen PD Puts the pen down so that moving the turtle draws a line. Turtle would move 150 pixels without leaving a line. That moving the turtle doesn't draw a line. Means "pen up." This command lifts the pen (turtle) from the screen so For example, wait random 600 would produce a random waiting period which varies from zero to 10 seconds. Wait 360 would cause a pause of 6 seconds. Pauses for a specified amount of time, (measured in 1/60 seconds),īefore executing the next command. *IMPORTANT NOTE: the brackets used in LOGO are next to the "P" key and do not require a shift. Repeat n repeats the actions listed in the command list an n number of times. The screen can alsoīe cleared and the pen brought home by clicking the "reset" button at Home returns the turtle to the start position at the center of the screen.Ĭlears the screen and returns the turtle to home. ST shows the turtle as a triangular cursor. Example: fd 100īK n moves the turtle backward n pixels. *Note: all LOGO commands are executed by hitting the "enter" key, or byĬlicking the "execute" button in the lower right of the LOGO screen.Īlmost all LOGO commands are NOT case-sensitive.įD n moves the turtle forward n pixels. In LOGO the pen is also called the TURTLE. Listed below are commonly used LOGO commands which are executed by the LOGO pen (cursor). Window gives quick access to cut and paste, and to transfer to the LOGO screen. This may be the better idea as many procedures are moreĮasily accomplished with "cut and paste." Keeping this page in a separate browser Or they can keep the LOGO screen and this page in separate browser windows, and switch back and forth as necessary.
