draw_v3.1 - a script to precisely draw on the screen with the turtle module
Execute the main() function and it opens the interface.
Every action is sent to the program thanks to key presses.
alpha, ln for/backwards and exp, log left/right.pi and square-root.sin.cos (presets) and tan (rgb).left parenthesis, plus and multiply.backspace.right parenthesis, minus and divide.square (x²).var (interface).Note that turtle doesn’t use the ion coordinate system: the origin (0,0) is in the very center of the screen. When dealing with angles, turtle uses degrees and describes 0° as “looking to the right”.
The drawing area starts blank and fills up 90% of the screen (ion coordinates 0,0 to 320,202).
There is a status bar, called the prompt, at the bottom which shows all the user values.
There are 3 prompt modes ; switch the shown mode with var.
When you need to enter a value, a specific input-prompt gets showed.
You can use the digits, minus and backspace to indicate the value and exe or ok to send.
Escape it without making changes to any program-value with divide.
