Code District:

The middle section of the editor is the code area, we are here to carry out various combinations of bricks, and control the use of role-modeling, stage background and sound like.

 

Right-click any empty area code area, it will pop up a menu, can be building blocks "undo" "redo" "finishing building blocks" "add a comment" "Delete blocks" and a series of operations.
