package com.fry.tetris;

import java.awt.Image;

/**

* 格子

* 每一个小格子，就有所在的行 列 和图片

*/

public class Cell {

private int row;

private int col;

//private int color;

private Image image;//格子的贴图

public Cell() {

}

public Cell(int row, int col, Image image) {

super();

this.row = row;

this.col = col;

this.image = image;

}

public int getRow() {

return row;

}

public void setRow(int row) {

this.row = row;

}

public int getCol() {

return col;

}

public void setCol(int col) {

this.col = col;

}

public Image getImage() {

return image;

}

public void setImage(Image image) {

this.image = image;

}

public void moveRight(){

col++;

//System.out.println("Cell moveRight()" + col);

}

public void moveLeft(){

col--;

}

public void moveDown(){

row++;

}

@Override

public String toString() {

return LBRXC"["+row+","+col+"]";

}

}

case 3: return new L();

case 4: return new O();

case 5: return new S();

case 6: return new Z();

}

return null;

}

public Cell[] getCells() {

return cells;

}

/** 下落 */

public void softDrop(){

}

}

}

}

cells[i].moveLeft();

}

}

cells[3].setRow(o.getRow()+s.row3);

cells[3].setCol(o.getCol()+s.col3);

}

/** 在 Tetromino 上添加方法 */

public void rotateLeft() {

index--;//index = 10001
