Aqa comp1 2016

The skeleton program allows the player to place their piece anywhere on the board, when in a real game, you can only place a piece if doing so actually TAKES an opponents piece. This is a core part of the game, so I imagine that this is quite likely to come up but I can't find a solution yet.

I solved it I was being an idiot and it tuned out to be simpler than i thought.
If anyone is stuck on this one let me know and I'll walk you through it

Hey i'm doing the comp1 exam as well but in vb.net. Mind explaining how you solved it please?

I sent you the solution check your inbox

can you send me the solution as well please?

I've PM'd you the solution

What language are you using? Would you be able to pm me the solution as well please

due to so many requests I'll post the solution here

Step 1) there should be a a function called CheckIfMoveIsValid, what you need to do is modify the if statement to this

If Board[Row, Column] = '"empty space" and(CheckIfThereArePiecesToFlip(Boar d, BoardSize, Row, Column, 1,0 = true
or CheckIfThereArePiecesToFlip(Boar d, BoardSize, Row, Column, -1, 0) = true
or CheckIfThereArePiecesToFlip(Boar d, BoardSize, Row, Column, 0, 1) = true
or CheckIfThereArePiecesToFlip(Boar d, BoardSize, Row, Column, 0, -1) = true)
Then MoveIsValid <== True
what this does is call the function to check if there are pieces to flip and the function will return true or false and if it returns true

Step 2) Make HumanPlayerTurn a global variable instead of a local variable in the PlayGame Function

Step 3)Then paste the following if statement in the function called CheckIfThereArePiecesToFlip right at the start of the function
If HumanPlayersTurn = true
Then Board[StartRow, StartColumn] := 'H'
Else Board[StartRow, StartColumn] := 'C'

when the function to check for flips is called it's called after the letter has been assigned to the game board cells so the flip function doesn't see an empty space but a letter in the place you entered the coordinates for, since we are calling it earlier before the letter gets assigned to the board the function still reads it as an empty space and will not work thats why in step 3 you have to add and if statement to temporarily assign the selected coordinate to hold a letter

if you still don't get it let me know

I have done every other possible problems we discussed on the first page of this thread and have solved them so if anyone is stuck just leave a message here. If I don't do the same language as you I can still provide a working algorithm to solve a problem

How about do everyone a HUGE favour and write the algorithms for every problem and post it?

Do you know how to allow diagonal flipping of pieces in VB Please

FlipOpponentPiecesInOneDirection(Board, BoardSize, Row, Column, 1, 1) FlipOpponentPiecesInOneDirection(Board, BoardSize, Row, Column, -1, 1) FlipOpponentPiecesInOneDirection(Board, BoardSize, Row, Column, -1, 1) FlipOpponentPiecesInOneDirection(Board, BoardSize, Row, Column, 1, -1)
try this, under the make move subroutine and it should hopefully work

This is unlikely, as there is no way of testing this reliably in the exam due to the computer choosing its moves at random.

I think they may ask something to do with counting the number of pieces of each type on the board, for example calculating the percentage of 'Human' pieces on the board compared to 'Computer' pieces.

Is this for the resit or the AS battleships , If it is for the AS , what is meant by flipping?
