Day 55: Errors in logic...

When I saw the error that I posted before, I just started to log all. Now I think I understand where this is happening: The tryToKill function: public int tryToKill(int color){ Ruleset ruleset=new Ruleset(); int killed=0; //return the number of killed stones ArrayList<integer> group=new ArrayList<>(); ArrayList<integer> liberties; boolean isDead; for(int i=0;i<this.getMainBoard().size();i++){ if(this.getMove(i)==color){ group=ruleset.getGroup(i, this); liberties=ruleset.getLiberties(group, this); //isDead=ruleset.TryKillingGroups(group, this); //if(isDead==true){ //if dead KILL! if(liberties.isEmpty()){ //if dead KILL! killed=group.size(); //first add dead stones to the "bowl" if(color==1){ //Add black stones to the bowl this.blackDeadStones=this.blackDeadStones+killed; }else{ // this.whiteDeadStones=this.whiteDeadStones+killed; } for(int j=0;j<group.size();j++){ this.setMove(group.get(j), 0); } } } } return killed; }
 Here should be the problem. And I guess there is a problem counting libertir There is the problem. And what I see is that tryToKill maybe is changing the main board. public ArrayList<integer> getLiberties(ArrayList<integer> group, Board board){ //given a group, I should count liberties. ArrayList<integer> liberties=new ArrayList<>(); //int groupPointer=0; for(int i=0;i<group.size();i++){ //search to the right if(board.getMove(group.get(i)+1)==0){ if(liberties.contains(group.get(i)+1)==false){ liberties.add(group.get(i)+1); } } //search to the left if(board.getMove(group.get(i)-1)==0){ if(liberties.contains(group.get(i)-1)==false){ liberties.add(group.get(i)-1); } } //search up if(board.getMove(group.get(i)-(board.getBoardSize()+1))==0){ if(liberties.contains(group.get(i)-(board.getBoardSize()+1))==false){ liberties.add(group.get(i)-(board.getBoardSize()+1)); } } //search down if(board.getMove(group.get(i)+(board.getBoardSize()+1))==0){ if(liberties.contains(group.get(i)+(board.getBoardSize()+1))==false){ liberties.add(group.get(i)+(board.getBoardSize()+1)); } } } return liberties; }

More news soon...
