Understanding the difference between objects and classes using a Logo or Turtle Graphics style turtle. Links to stuff from the video: + TurtlesStarter.zip. This topic started in this recent post, where I introduced a simple turtle graphics engine for AutoCAD implemented in C#. My eventual aim is still to implement a subset of the Logo programming language in F#, calling through to this C# engine, but for now I've been side-tracked: I'm simply having too much fun with the engine itself and exploring the possibilities of turtle graphics inside.

Constructor Detail

Turtle

Constructs a turtle.

Method Detail

up

Picks the Turtle's tail up so it won't draw on the screen as it moves.

down

Lowers the Turtle's tail down so it will draw on the screen as it moves.

left

Rotates the Turtle counterclockwise.

Parameters:: delta - an angle in degrees.

right

Rotates the Turtle clockwise.

Parameters:: delta - an angle in degrees.

forward

Moves the Turtle forward.

Parameters:: step - a distance measured in pixels.

dot

Places a dot at the Turtle's present position.

dot

Places a dot at the Turtle's present position.

Parameters:: size - the width in pixels.

dot

Places a dot at the Turtle's present position.

Parameters:: size - the width in pixels.; color - name of a color or a 6-digit hex color string (e.g. '00FF00' for green)

dot

Places a dot at the Turtle's present position.

Parameters:: color - name of a color or a 6-digit hex color string (e.g. '00FF00' for green)

write

Write text centered a the Turtle's current position.

Parameters:: text - message to be written on the screen.

write

Write text centered a the Turtle's current position.

Parameters:: text - message to be written on the screen.; angle - the angle in degrees that the text is rotated counterclockwise.

write

Write text on the screen.

Parameters:: x - the x coordinate of the center of the text.; y - the y coordinate of the center of the text.; text - message to be written on the screen.; angle - the angle in degrees that the text is rotated counterclockwise.

speed

Sets the delay in milliseconds between execution of Turtle commands.

Parameters:: t - the delay in milliseconds.

backward
