Hopefully this helps:
Basically your draw code expected the tree position table to be structured differently than it was.
Let me know if you have questions!
How it is possible to carry out cutting of a tree? Or they preliminary it is necessary to write down in an array?
I had the idea to draw a rectangle painting area with a tree and over the top to draw a stub. But I do not know how to keep it.
An easy way would be to store a 'state' for the tree. Right now, you're storing 2 pieces of information per tree:
-x value
-y value
If you add a third value for its state, then you can do something like this:
