Questions tagged [turtle-graphics]

A method for drawing computer graphics using a cursor, known as a turtle. Turtle-graphics supports game development, visualizations, animation, etc.

A method for drawing graphics, which uses a cursor (known as a turtle) for specifying the position, the direction and the attributes (color, line width, etc.) of the lines being drawn. It was popularized by the Logo programming language. Similar functionality can currently be found in Python's turtle module, which is part of its standard library.

The turtle runs commands sent to it sequentially, including moving forwards or backwards, turning/rotating, and raising or lowering "the pen" determining if the turtle is currently drawing a line while moving. This output pathway of the turtle can additionally be post-processed into 3-dimensional models. Depending upon the implementation, the turtle may traverse 2D, 3D, or N-dimensional coordinate spaces.

My turtle is not detecting inputs and it can just go past the border

So basically, I can't move my turtle at all, even though there are functions for it. And, when I could, when it hit the border it would just keep going. I've tried moving the position of the functions but it doesn't work. I have all the functions…
