Вот как я закодировал логику. Измените его в соответствии с вашими потребностями
отрим 2D сетку сn rows а такжеn columns (здесь 75х75). Символы (токены) рисуются в каждой ячейке по щелчку мыши. Код ниже используется для рисования линий сетки и символов внутри ячеек:
class DrawCanvas extends JPanel{
@Override
public void paintComponent(Graphics g){
super.paintComponent(g);
setBackground(Color.WHITE);
//Lines
g.setColor(Color.BLACK);
for(int ligne = 1; ligne < ROWS; ++ligne){
g.fillRoundRect(0, cellSize * ligne - halfGridWidth, canvasWidth - 1,
gridWidth, gridWidth, gridWidth);
}
for(int colonne = 1; colonne < COLS; ++colonne){
g.fillRoundRect(cellSize * colonne - halfGridWidth, 0
, gridWidth, canvasHeight - 1,
gridWidth, gridWidth);
}
//Symbols
Graphics2D g2d = (Graphics2D)g;
g2d.setStroke(new BasicStroke(symbolStrokeWidth,
BasicStroke.CAP_ROUND, BasicStroke.JOIN_ROUND));
for(int ligne = 0; ligne < ROWS; ++ligne){
for(int colonne = 0; colonne < COLS; ++colonne){
int x1 = colonne * cellSize + cellPadding;
int y1 = ligne * cellSize + cellPadding;
if(board[ligne][colonne] == Token.CERCLE_ROUGE){
g2d.setColor(Color.RED);
g2d.drawOval(x1, y1, symbolSize, symbolSize);
g2d.fillOval(x1, y1, symbolSize, symbolSize);
} else
if(board[ligne][colonne] == Token.CERCLE_BLEU){
int x2 = colonne * cellSize + cellPadding;
g2d.setColor(Color.BLUE);
g2d.drawOval(x1, y1, symbolSize, symbolSize);
g2d.fillOval(x2, y1, symbolSize, symbolSize);
}
}
}
С кодом ниже, я могу найти всех соседей данной ячейки:
private void neighbours(int col, int row) {
//find all serouding cell by adding +/- 1 to col and row
for (int colNum = col - 1 ; colNum <= (col + 1) ; colNum +=1 ) {
for (int rowNum = row - 1 ; rowNum <= (row + 1) ; rowNum +=1 ) {
//if not the center cell
if(! ((colNum == col) && (rowNum == row))) {
//make sure it is within grid
if(withinGrid (colNum, rowNum)) {
System.out.println("Neighbor of "+ col+ " "+ row + " - " + colNum +" " + rowNum );
}
}
}
}
}
//define if cell represented by colNum, rowNum is inside grid
private boolean withinGrid(int colNum, int rowNum) {
if((colNum < 0) || (rowNum <0) ) {
return false; //false if row or col are negative
}
if((colNum >= COLS) || (rowNum >= ROWS)) {
return false; //false if row or col are > 75
}
return true;
}
Рассмотрим содержимое ячеек:
public enum Token{
VIDE, CERCLE_BLEU, CERCLE_ROUGE
}
Теперь я хочу знать, есть ли способ определить, что содержит ячейка: она пуста:Token.VIDEимеетToken.CERCLE_BLEU или имеетToken.CERCLE_ROUGE. И как я могу этого достичь.
