A Bigger, Slower, Bolder Turtle
In some circumstances, especially when working with young children, it is useful to have a bigger, slower, bolder turtle so that its movements can be watched step-by-step. Terrapin Logo allows you to easily adjust both the turtle size and the speed at which it moves when executing commands. In addition you can adjust the width of the line that the turtle draws so it makes bolder drawings.
Adjustments to turtle size, speed, and line width can be made via the Turtle Center dialog box or by commands. You can open the Turtle Center by clicking on the Turtle Tool button or by right-clicking (in Windows) or Control-clicking (on the Mac) the turtle itself. The Control Center offers sliders that can be used to adjust the turtle scale and crawl speed and an edit box to enter an integer to represent the line width (in pixels).
Pairs of commands are also available that allow you to manage turtle size, speed, and line width. TURTLESIZE, TURTLESPEED, and WIDTH report the current size, speed, and line width of the first active turtle. SETTURTLESIZE, SETTURTLESPEED, and SETWIDTH can be used to adjust these attributes. Consult the Reference Manual, Quick Reference, or on-line Help from within Logo for more information on using these commands.
Consult the Reference Manual section on “Customizing your Logo environment” in the Logo Elements chapter for information on making your changes to turtle size, speed, and line width part of Logo each time you use it.
The Logo VER commands reports the version of Logo that you are currently running along with the date of its compilation. When you have a question or seek help for Terrapin Logo, type the VER command in the Listener window and report the version and date of Terrapin Logo you are using to expedite a response.
