    <p>I am making a game based of the asian board game called "go". I am currently trying to implement the capturing system. Basically once all of the liberties a stone has have been surrounded by the enemy the stone is taken. In the screenshot the black stone should be removed. <a href="https://imgur.com/unHEdko" rel="nofollow noreferrer">http://imgur.com/unHEdko</a></p> <p><img src="https://i.stack.imgur.com/Evo9y.png" alt="enter image description here"></p> <p>As well, if you connect stone together the liberties are combined, for example this is how you would capture two stones. <a href="https://imgur.com/pPBVRkC" rel="nofollow noreferrer">http://imgur.com/pPBVRkC</a> also here is another example of black being captured. /lbg8BsC</p> <p><img src="https://i.stack.imgur.com/AFBy4.png" alt="enter image description here"></p> <p>I have a 2D array thats 19x19 that stores all my stone locations. Black is represented by 1 while white is 2. This is my array print out from the first image. </p> <pre><code>0000000000000000000 0000000000000000000 0000000000000000000 0000000000000000000 0000000000000000000 0000000000000000000 0000000000000000000 0000000000000000000 0000000002000000000 0000000021200000000 0000000002000000000 0000000000000000000 0000000000000000000 0000000000000000000 0000000000000000000 0000000000000000000 0000000000000000000 0000000000000000000 0000000000000000000 </code></pre> <p>As you can see the black stone in the middle is surrounded by white stones. In this case it easy to check if that stone is surrounded, but I don't know how to do it once you have multiple stones like in the two other screen shots above. Any help is greatly appreciated. </p>

    1. COI cant tell as we cant see any code in post, it would be help. However here is pointer, first check for black stone is surrounded by whites and if you encounter another black (lets say bottom side) then go to that position and check for remaining (ie left right and bottom) procedure for that location, make sure that you have checked whites for first black.
