Laya连线小游戏
Laya连线小游戏
游戏规则
- 通过连接不同颜色的方块来实现连一连
- 连线不可重复，就是一条线不能和另外一条线撞一起
- 最后所有连线要占据整个空间
游戏资源
创建Item
线条可以分为上左下右，通过显示和隐藏达到画线的效果。
譬如item1到item2，通过判断两者posX，posY，item1调用方法showLine(3)显示line3，item2调用方法showLine(1）显示line1。
Item.ts。
import { ui } from "../ui/layaMaxUI";
export class Item extends ui.view.ItemUI{
public colorType:number = 1;//定义线条颜色
public type:number = 0;//类型
public posX:number = 1;//位置x
public posY:number = 1;//位置y
public isLinkList:boolean = false;//是否已经连过了
/* 创建item */
public static createItem():Item{
let item:Item = new Item();
item.line1.visible = false;
item.line2.visible = false;
item.line3.visible = false;
item.line4.visible = false;
return item;
}
/* 设置线条颜色 */
public setLineColor(value:number):void{
this.isLinkList = true;
this.colorType = value;
for(let i:number = 1; i <= 4; i++){
this["line" + i].skin = "res/ui/icon/line_line" + value + ".png";
}
}
/* 设置icon */
public setIcon(value:number):void{
this.type = value;
if(value > 0){
this.icon.skin = "res/ui/icon/line_icon" + value + ".png";
}else{
this.icon.skin = "";
}
}
/* 显示上或下或左或右线条 */
public showLine(value:number):void{
switch(value){
case 1:
this.line1.visible = true;break;
case 2:
this.line2.visible = true;break;
case 3:
this.line3.visible = true;break;
case 4:
this.line4.visible = true;break;
default:
this.line1.visible = false;
this.line2.visible = false;
this.line3.visible = false;
this.line4.visible = false;
this.isLinkList = false;
break;
}
}
}
游戏界面创建
创建GameView.ts，类GameView继承自该界面

通过行数5，列数5创建item，添加到panelNode节点上，初始化画线面板。
/* 初始化画线面板 */ private initDrawLinePanel():void{ let item:Item; for(let i:number = 0; i < this.row; i++){ for(let j:number = 0; j < this.column; j++){ item = Item.createItem(); item.pos(j * this.ITEM_WIDTH,i * this.ITEM_HEIGHT); item.posX = j; item.posY = i; item.setIcon(this.dataArr.shift()); this.panelNode.addChild(item); this.itemArr.push(item); } } let panelWidth:number = this.ITEM_WIDTH * this.column; let panelHeight:number = this.ITEM_HEIGHT * this.row; this.panelNode.size(panelWidth,panelHeight); this.panelNode.x = -0.5 * panelWidth; this.panelNode.y = -0.5 * panelHeight; }
通过鼠标位置，计算出posX,posY，拿到对应的item
鼠标全局位置转为panelNode局部位置，计算出posX，posY，再从itemArr拿到对应的item
this.tempPoint.setTo(Laya.MouseManager.instance.mouseX,Laya.MouseManager.instance.mouseY); let point:Laya.Point = this.panelNode.globalToLocal((this.tempPoint)); let posX:number = Math.floor(point.x / this.ITEM_WIDTH); let posY:number = Math.floor(point.y / this.ITEM_HEIGHT); let index:number = posY * this.column + posX; let item:Item = this.itemArr[index];
鼠标按下
鼠标点击时，有俩种情况，才可以画线
第一种情况，点击到颜色方块
第二种情况，不是点击到 颜色方块，但是点击到连线的末端，这时可以继续连线
/* 鼠标按下 */ private onMouseDown():void{ //全局坐标转为panelNode局部坐标 this.tempPoint.setTo(Laya.MouseManager.instance.mouseX,Laya.MouseManager.instance.mouseY); let point:Laya.Point = this.panelNode.globalToLocal((this.tempPoint)); let posX:number = Math.floor(point.x / this.ITEM_WIDTH); let posY:number = Math.floor(point.y / this.ITEM_HEIGHT); let index:number = posY * this.column + posX; let item:Item = this.itemArr[index];//拿到对应的item if(item.type > 0){//点击到有颜色的item this.canDraw = true; this.currentList = this["list" + item.type]; this.currentList.clear(); this.currentList.append(item); }else{//点击到没有颜色的item if(item.isLinkList){//连过了 this.currentList = this["list" + item.colorType]; let tail:Item = this.currentList.getTail().item; if(item == item){//判断该item是否属于链表尾节点 this.canDraw = true; } } } }
鼠标滑动，连线
连线时，只有跟该线线尾相邻才可以连接
滑到不同颜色节点时断开连接
如果滑动到的已经连接过了，就切割该链表
如果滑动到的节点已经被其它节点连接过了，就切割连接过的链表
/* 鼠标滑动 */ private onMouseMove():void{ if(!this.canDraw) return; //全局坐标转为panelNode局部坐标 this.tempPoint.setTo(Laya.MouseManager.instance.mouseX,Laya.MouseManager.instance.mouseY); let point:Laya.Point = this.panelNode.globalToLocal((this.tempPoint)); let posX:number = Math.floor(point.x / this.ITEM_WIDTH); let posY:number = Math.floor(point.y / this.ITEM_HEIGHT); let index:number = posY * this.column + posX; let item:Item = this.itemArr[index];//拿到对应的item let tail:Item = this.currentList.getTail().item;//链表尾 if((posX == tail.posX && Math.abs(posY - tail.posY) == 1) || (posY == tail.posY && Math.abs(posX - tail.posX) == 1)){//必须与链表尾相邻(上下左右) if(item.type <= 0 || item.type == tail.colorType){//滑动到没有颜色的节点或者是颜色一样 let position:number = this.currentList.positionOf(item); if(position < 0){ if(item.isLinkList){//已经在其它链表里了 let list:LinkList = this["list" + item.colorType] list.slice(list.positionOf(item) - 1); } this.currentList.append(item);//添加到链表 this.isGetVictory();//是否通关 if(item.type > 0){ this.canDraw = false; } }else{ this.currentList.slice(position);//切割链表 } }else{ this.canDraw = false; } }else{ if(item != this.currentList.getTail().item){//此时滑动到的点不是链表尾,才不能画线(在当前的点滑来滑去还是能画线) this.canDraw = false; } } }
判断是否连接完成
只需要遍历所有链表，判断链表长度是否等于面板上的方格总数
/* 是否通过 */ private isGetVictory():boolean{ let count:number = 0 for(let i:number = 1; i <= 5;i ++){//遍历所有链表，判断链表长度是否等于面板上的方格总数 count += this["list" + i].size() } if(count == this.row * this.column){ return true; } return false; }

设置线条

item链表添加节点
需要设置一下当前节点跟上一个节点的线条

item链表截取节点

清空item链表
将链表清空，item线条全部隐藏
/* 清空链表 */ public clear():void{ let currentNode:Node = this.head; while(currentNode){ currentNode.item.showLine(0); currentNode = currentNode.next; } this.head = null; this.tail = null; this.length = 0; }
