Flesh out board module

[RobertCochran]

The board module ought to have at least two more functions -

move_is_valid(board, column) - Returns True if the column has space for more
checkers, False if not.

drop_token(board, column, color) - Puts a color piece in the columnith
column. Validity of move should be checked before hand with move_is_valid().

Can you please help me?

I'm more than happy to help you, but you're the one who is going to be doing the
work. I'm only going to help when you get stuck and you've tried at least a few
different things. If you're going to ask for help, I expect to see the code
you're having trouble with (in plain text), along with a list of things you've
attempted to solve the problem. Without these things, I'm not going to answer
questions. There is a symmetry in asking questions - if you expect me to spend
time on your question, spend your time providing what I've asked for so that
your question is worth spending time on.

We're (largely) volunteers. We take time out of busy lives to answer
questions, and at times we're overwhelmed with them. So we filter
ruthlessly. In particular, we throw away questions from people who appear to
be losers in order to spend our question-answering time more efficiently, on
winners.

If you find this attitude obnoxious, condescending, or arrogant,
check your assumptions. We're not asking you to genuflect to us — in fact,
most of us would love nothing more than to deal with you as an equal and
welcome you into our culture, if you put in the effort required to make that
possible. But it's simply not efficient for us to try to help people who are
not willing to help themselves. It's OK to be ignorant; it's not OK to play
stupid.

Sorry, I'm not trying to act stupid. The thing is that I don’t know what how and where I supposed to type the code. Look on yammer there's my problem.

And I wasn't claiming that you were, by the way.

So, let's think about it like this -

drop_token() needs take the board, find the column specified, then drop the
token in, respecting the fact that gravity needs to work and needs to not clip
through other tokens (ie, if the column is already 3 high, then the new token
should go directly on top, making it 4 high). Remember that the board should be
arranged like a computer screen - (0, 0) is the top left of the board.

move_is_valid() is a little easier. Assuming that drop_token() has done its
job and the board is valid from a physics perspective, then all it needs to do
is check if the top row is clear. If it's clear, then the move is valid. It's
not otherwise.

Thank You! ok, so you said ”drop_token(board, column, color) - Puts a color piece in the column column.” so I don’t under stand where dose the “color” come from? ( I know that the color means token right?)

Your caller will provide color. This function is meant to be called by the
user interface code to interact with the board, rather than interacting with the
board directly.

[pavlenko-yann]

So, "color" it will interact with the UI and tell it that it should drop it? (if there is space)

[RobertCochran]

I don't understand what you're trying to get across. Please rephrase.

[pavlenko-yann]

OK, i guess i did not understand what you meant by

"Your caller will provide color. This function is meant to be called by the
user interface code to interact with the board, rather than interacting with the
board directly"

[RobertCochran]

The code that calls your function will hand you the color you need to use. You then take that color and drop it in the appropriate column, respecting gravity (bottom-most slot) and physics (still open space in the column).

[pavlenko-yann]

ok

[pavlenko-yann]

so about the drop token. How do I make the code to know where to drop?
drop.color(column.(8, 8))??? .ect
Thing is that I don't know how to even type it to work.

[Abananiac]

Don't we pull that information from the user input?

[pavlenko-yann]

oh ya, but how to I set it up so that it will be able to get that information from the user input.

[RobertCochran]

You provide the parameters to the function. The user input code is responsible for giving it to you.
