Controlling a turtle's speed with a slider

You can adjust the speed of a moving turtle by using a slider. If you have a project open, close it by selecting a new project from the File Menu.

Creating a Slider

Select the slider button and click on the page.

The slider's dialog box opens. Change the name to speed.

Click the OK button and it will appear on the screen.


Now hatch another turtle.

Right click on this turtle and give it the instruction

Fd speed wait 1

and select many times



Now click on the turtle to get it to move and change the slider to increase and decrease its speed.



Save this project as Inter1 and have your teacher check your work. You are now ready to give instructions to more than one turtle.
