EDIT:

Trying to implement Shiro's solution:

private Array<Tile> matchedTiles = new Array<Tile>(); //... private void checkVertical(int row, int col){ Tile toCheck = array[row][col]; matchedTiles.add(toCheck); if(toCheck.getRow() < 7 && array[row + 1][col] == array[row][col]){ //check 1 up matchedTiles.add(array[row + 1][col]); } if(toCheck.getRow() < 6 && array[row + 2][col] == array[row][col]){//check 2 up matchedTiles.add(array[row + 2][col]); } if(toCheck.getRow() > 0 && array[row - 1][col] == array[row][col]){//check 1 down matchedTiles.add(array[row - 1][col]); } if(toCheck.getRow() > 1 && array[row - 2][col] == array[row][col]){//check 2 down matchedTiles.add(array[row - 2][col]); } if(matchedTiles.size >= 3){ //if we find a match for(Tile t : matchedTiles){ array[t.getRow()][t.getCol()].setId(8); //actual array of tiles on board } matchedTiles = new Array<Tile>(); }else{ matchedTiles = new Array<Tile>(); } }
