What is Animations in Logo Programming Language?

Logo is an educational programming language that is well-known for its use of turtle graphics, which allows creating line or vector graphics through commands for movement and drawing.To create animations in Logo, programmers can leverage a few key commands:

PENERASE Command

The PENERASE command sets the pen’s mode to “erase”, allowing the program to erase the image at its previous location before drawing it at a new position. This is crucial for creating smooth animations without leaving behind a trail of previous images.

PENPAINT Command

The PENPAINT command sets the pen’s mode back to “paint”, restoring the pen to normal drawing functionality after using PENERASE

Animation Using Two Versions of an Image

One common technique for creating animations in Logo is to have two slightly different images of an object, like a standing figure and a jumping figure. The program can then rapidly switch between displaying the two images to create the illusion of motion.By using these Logo commands and techniques, programmers can bring static graphics to life through animation, which is the foundation for video games and other dynamic visual applications

Example of Animations in Logo Programming Language

This example showcases how to create a captivating spinning square animation using the Logo programming language. Logo is renowned for its educational approach and distinctive turtle graphics, making it an ideal tool for visually demonstrating programming principles through dynamic, interactive animations.

to spin-square
  repeat 36 [
    repeat 4 [
      forward 50
      right 90
    ]
    right 10  ;; adjust the angle for spinning effect
  ]
end

spin-square

Explanation this code:

• Define the Procedure (`to spin-square`):
  • We define a procedure named `spin-square` to encapsulate the instructions for drawing the spinning square.

• Outer Loop (`repeat 36 [...]`):
  • The outer loop (`repeat 36 [...]`) ensures that the turtle completes a full circle by repeating the following block 36 times.

• Inner Loop (`repeat 4 [...]`):
  • Inside the outer loop, the inner loop (`repeat 4 [...]`) directs the turtle to draw a square by moving forward 50 units and turning right 90 degrees four times.

• Rotation (`right 10`):
  • After completing each square (inside the inner loop), `right 10` rotates the turtle slightly to simulate a spinning motion. Adjust this angle to change the speed or direction of the spin.

• End of Procedure (`end`):
  • `end` marks the end of the `spin-square` procedure definition.

• Run the Animation (`spin-square`):
  • Finally, we call the `spin-square` procedure to execute the animation. The turtle will execute the defined instructions, resulting in a spinning square animation on the screen.
