I_EDITOR is a programming game. The goal is to write simple scripts to reproduce a drawing on screen. The commands used in the scripts move a pointer (“turtle”). The pointer has a pen, which can be up or down. When the pen is down, each move lays a print. There are additional instructions to make calculus, evaluate conditions and call previous declared sequences. The syntax and semantic are organized in language called I_CORE.

Now you can download the manual !

Le manuel en français est disponible.

Try to reproduce the blueprints or play with the sandbox...
I will add a score and more blueprints soon ;-)

In the main menu:
Choose a blueprint or the sandbox (up/down, x)

In the editor:
Choose the command in the first column (up/down, x) or return to the main menu (o)
Change column (left/right)

Change the value in the second colum (x, then left/right to decrease/increase)
Delete instruction in the second colum with (o)

Have a look on i_core thread to have more explanation about the language "I".

I will make a tutorial soon and post a link and additional information here.

I made a simple tree :)

(a better stop condition would speed it up- it spends too long drawing tiny branches)

Well done, you rock !!!

You can accelerate the rendering process in the M:DRAW method. At the end, change from



 while i>0 and self.vm:state()!=3 do

where i is the number of steps to do (i=4).

If you see something strange in the manual (errors, missing words, ...) or if you have ideas about additional content, let me know :-)
