Cocos2d-JS 开发小笔记

前端之家收集整理的这篇文章主要介绍了Cocos2d-JS 开发小笔记前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

关于cocos2d-JS开发看过两本书,《Cocos2d-JS开发之旅》和《Cocos2d-x实战-JS卷》,两本书都不错,各有特点,但是在实际开发中,有很多关于常用的控件这两本书并没有详细的阐述,因此,在接下来的开发中,我会把一些常用的控件,比如TableView和CollectionView之类的使用技巧和说明,会不断更新在此文章中。

1、Cocos Studio ListView 控件监听

        if(!cc.Layer.prototype.init.call(this))
        {
            return false;
        }
        var objView = ccs.csLoader.createNode(res.StageInfo_Json);
        this.addChild(objView);

        this._tableViewItem1 = ccui.helper.seekWidgetByName(objView,"Tablelist_Item1");
        this._tableViewItem1.setScrollBarEnabled(false);
        this._tableViewItem1.addEventListener(this.onSelectedItemEvent.bind(this),this);
        this._tableViewItem2 = ccui.helper.seekWidgetByName(objView,"Tablelist_Item2");
        this._tableViewItem2.setScrollBarEnabled(false);
        this._tableViewItem2.addEventListener(this.onSelectedItemEvent.bind(this),this);
    onSelectedItemEvent: function (sender,type) {
        switch (type)
        {
            case ccui.ListView.EVENT_SELECTED_ITEM:
                break;
            case ccui.ListView.ON_SELECTED_ITEM_END:
                // alert(sender.getName() + "  " + sender.getCurSelectedIndex());
                this.showDetail(sender.getCurSelectedIndex());
                break;
            default:
                break;
        }
    }
说明:很多时候使用Cocos Studio工具生成的控件,仅仅使用一个坐标而已。
    var listView = ccui.helper.seekWidgetByName(objView,"Tablelist");
    listView.setScrollBarEnabled(false);
    this._tableView = new cc.TableView(this,listView.getContentSize());
    this._tableView.x = listView.x;
    this._tableView.y = listView.y;
    this._tableView.setDelegate(this);
    this.addChild(this._tableView);
    numberOfCellsInTableView: function (table) 
    {
        return this._players.length;
    },tableCellSizeForIndex: function (table,idx) 
    {
        return this._cellSize;
    },tableCellAtIndex: function (table,idx)
    {
        var att = this._players[idx];
        var cell = table.dequeueCell();
        if(cell == null)
        {
            cell = new FightListCell();
        }
        cell._player = att;
        cell._labelName.setString(att.Name);
        cell._labelFight.setString("战斗力:" + DataManager.getNumberText(att.Fight));
        cell._labelReward.setString(DataManager.getNumberText(att.PresentRes.Amount));
        cell._TGAmount = this._res.TGAmount;
        cell._res = this._res;
        var url = NetProxy.HostBaseUrl + att.IconId;
        cell._imgIcon.setScale(0.8);
        DataManager.loadUrlImage(url,cell._imgIcon);
        var sprite = cc.Sprite.create("res/gui/PlayerBox.png");
        sprite.setPosition(cell._imgIcon.getPosition());
        cell.addChild(sprite);
        return cell;
    },tableCellTouched:function (table,cell)
    {
    }

如果需要多行多列显示,那么就得用CollectionView了:
	var listView = ccui.helper.seekWidgetByName(objView,"Tablelist");
        listView.setScrollBarEnabled(false);
        this.m_tableView = new cc.CollectionView(this,cc.size(listView.getContentSize().width,listView.getContentSize().height));
        this.m_tableView.setDirection(cc.SCROLLVIEW_DIRECTION_VERTICAL);
        this.m_tableView.x = listView.getPositionX();
        this.m_tableView.y = listView.getPositionY();
        this.m_tableView.setDelegate(this);
        this.addChild(this.m_tableView);

    tableCellSizeForIndex: function (table,idx) {
        if(this.m_type == 3 && (idx > this.m_flag-5 && idx <= this.m_flag))
        {
            return cc.size(110,25);
        }
        return this.m_cellSize;
    },numberOfCellsInTableView: function () {
        if(!this.m_items){
            return 0;
        }
        return this.m_items.length;
    },cellSizeForTable: function (table) {
        // return table.getContentSize();
        return cc.size(580,130);
    },idx) {

        var itemAtt = this.m_items[idx];
        var cell = null;
        // var cell = table.dequeueCell();
        if(!cell){
            cell = new InventoryCell();
        }
        cell.m_inventory = itemAtt;

        if(itemAtt.Id != 0){            //空行的Id==0
            var pic = "";
            if(this.m_type == 1)
            {
                cell.m_level.setString("Lv." + itemAtt.Level);
                pic = "res/pic/Equip/" + itemAtt.IconId + ".png";
            }
            else if(this.m_type == 2)
            {
                cell.m_level.setString(itemAtt.Amount);
                pic = "res/pic/Gems/" + itemAtt.IconId + ".png";
            }
            else if(this.m_type == 3)
            {
                if(idx < this.m_gemsNoEquip.length)
                {
                    cell.m_level.setString(itemAtt.Amount);
                }
                else
                {
                    cell.m_level.setString(itemAtt.EqpAmount);
                }
                pic = "res/pic/Gems/" + itemAtt.IconId + ".png";
            }
            else if(this.m_type == 4)
            {
                cell.m_level.setString(itemAtt.Amount);
                pic = "res/pic/Gems/" + itemAtt.IconId + ".png";
            }
        }
        else
        {
            if(idx == this.m_flag-4)
            {
                cell = new CombatCell();
                cell._Time.setVisible(false);
                cell._Info.setString("  ------已装备宝石------")
            }
            else
            {
                cell.m_level.setVisible(false);
                cell.m_image.setVisible(false);
                // cell.m_Box.setVisible(false);
            }
            return cell;
        }
        // this.changeNodeTexture2(pic,"image_Equipment",cell);
        this.createImage2(this.createIcon(itemAtt.IconId),cell);
        return cell;
    },tableCellTouched: function (table,cell) {
        if(cell.m_inventory.Id != 0){
            if(this.m_type == 1)
            {
                // SceneManager.addLayer(cc.LAYER_EQUIPUI,cell.m_inventory);
                var ui = SceneManager.addLayer(cc.LAYER_EQUIPUI,null,true,cc.LAYER_ANI_NONE,true);
                if (ui)
                {
                    //替换装备与装备相关操作
                    ui.initEquipUI(null,cell.m_inventory);
                }
            }
            else if(this.m_type == 3)
            {
                SceneManager.addLayer(cc.LAYER_GEMINFO,cell.m_inventory);
            }
            else
            {
                SceneManager.addLayer(cc.LAYER_ITEMINFO,cell.m_inventory);
            }
        }
    }   
CollectionView比TableView需要多实现一个方法,CellSizeForTable return table.getContentSize(); 但这样写,我这里出现bug,刷新列表时,即

this.m_tableView.reloadData(),会出现所有行都重叠到第一行中的bug,debug发现table.getContentSize的值为(0,0)所致。所以索性直接传入 return cc.size(580,130);

2、TableView实现可拖动的地图

/**

WorldMapCell = cc.TableViewCell.extend({
    _btnStage: [],_imgPath: [],_wordMap: null,_imgPosition: null,ctor: function () {

    },init: function () {
        this._super();
        var cell = ccs.csLoader.createNode(res.WorldMapCell_Json);
        this.addChild(cell);
        for(var i = 0; i < 30; i++)
        {
            this._btnStage[i] = ccui.helper.seekWidgetByName(cell,"btnStage" + (i+1));
            this._btnStage[i].setVisible(false);
            this._btnStage[i].addTouchEventListener(this.onButtonClick,this);
            if(i < 29)
            {
                this._imgPath[i] = ccui.helper.seekWidgetByName(cell,"WorldMap_Path" + (i+1));
                this._imgPath[i].setVisible(false);
            }
        }
        this._imgPosition = ccui.helper.seekWidgetByName(cell,"PlayerMarker");
        this._imgPosition.setScale(0.4);
        return true;
    },onButtonClick: function (sender,type) {

        {
            case ccui.Widget.TOUCH_ENDED:

                {
                    SceneManager.addLayer(cc.LAYER_STAGEINFO,sender.getName().substr(8));
                }
                break;
            default:

    }
