Cocos2d-js05-添加身体和移动身体

1、检测蛇是否吃到食物，代码：

  //检测蛇是否吃到食物
if(this._head.now_col==this._food.now_col && this._head.now_row==this._food.now_row){//播放音效cc.audioEngine.playEffect(res.bg_effect);cc.log("蛇吃到了食物！");//添加分数this.m_score += 100;score.setString("分数:"+this.m_score);//重置食物的位置this._food.now_row = Math.round(Math.random()*9);this._food.now_col = Math.round(Math.random()*9);this._food.setPosition(cc.p(this._food.now_col*63,this._food.now_row*63));//添加蛇的身体this._snakeBody = SnakeGame.create(2);this._snakeBody.setScale(0.9);if(SNAKE_BODY.length == 0 || SNAKE_BODY.length == null){switch (dir){case SNAKE_DIR.UP:this._snakeBody.now_row = this._head.now_row - 1;this._snakeBody.now_col = this._head.now_col;break;case SNAKE_DIR.DOWN:this._snakeBody.now_row = this._head.now_row + 1;this._snakeBody.now_col = this._head.now_col;break;case SNAKE_DIR.LEFT:this._snakeBody.now_row = this._head.now_row;this._snakeBody.now_col = this._head.now_col + 1;break;case SNAKE_DIR.RIGHT:this._snakeBody.now_row = this._head.now_row;this._snakeBody.now_col = this._head.now_col - 1;break;default :break;}cc.log("里面没有身体，添加一个！");}else{switch (dir){case SNAKE_DIR.UP:this._snakeBody.now_row = this._snakeBody.now_row - 1;this._snakeBody.now_col = this._snakeBody.now_col;break;case SNAKE_DIR.DOWN:this._snakeBody.now_row = this._snakeBody.now_row + 1;this._snakeBody.now_col = this._snakeBody.now_col;break;case SNAKE_DIR.LEFT:this._snakeBody.now_row = this._snakeBody.now_row;this._snakeBody.now_col = this._snakeBody.now_col + 1;break;case SNAKE_DIR.RIGHT:this._snakeBody.now_row = this._snakeBody.now_row;this._snakeBody.now_col = this._snakeBody.now_col - 1;break;default :break;}cc.log("里面有身体，添加一个！");}//添加到数组中去SNAKE_BODY.push(this._snakeBody);this.getChildByTag(111).addChild(this._snakeBody,2);this._snakeBody.setPosition(cc.p(this._snakeBody.now_col*63,this._snakeBody.now_row*63));
}

2、移动所有的身体，代码：

//移动所有的身体
if(SNAKE_BODY.length != 0){var Snode = null;for(var i = SNAKE_BODY.length - 1; i >= 0; i--){Snode = SNAKE_BODY[i];if(i == 0){switch (dir){case SNAKE_DIR.UP:Snode.now_row = this._head.now_row - 1;Snode.now_col = this._head.now_col;break;case SNAKE_DIR.DOWN:Snode.now_row = this._head.now_row + 1;Snode.now_col = this._head.now_col;break;case SNAKE_DIR.LEFT:Snode.now_row = this._head.now_row;Snode.now_col = this._head.now_col + 1;break;case SNAKE_DIR.RIGHT:Snode.now_row = this._head.now_row;Snode.now_col = this._head.now_col - 1;break;default :break;}}else{Snode.now_col = SNAKE_BODY[i-1].now_col;Snode.now_row = SNAKE_BODY[i-1].now_row;}Snode.setPosition(cc.p(Snode.now_col*63,Snode.now_row*63));}
}
