cocoscreator笔记（二）DataManager

定义如下：

class DataMgr {
    constructor() {
        this.instance = null;
        this.getInstance = function ()
        {
            if(this.instance == null)
            {
                this.instance = new DataMgr();
            }
            return this.instance;   
        }

        this.stageData = new Array(); // 所有关卡数据容器

        // 函数声明
        DataMgr.prototype = {
            loadAllDatas : loadAllDatas,
            loadStage : loadStage,
            getStageDataByID : getStageDataByID,
        }
        
        function loadAllDatas() {
            this.loadStage();
        }

        function loadStage() {
            var self = this;
            cc.loader.loadRes("config/t_stage",function(err,result){
                if(err != null)
                {
                    console.log("stage mgr load error",err);
                    return ;
                }
                self.stageData = result.json;
            });
        }

        function getStageDataByID(_id)
        {
            for(var idx in this.stageData)
            {
                if(this.stageData[idx].id == _id)
                {
                    return JSON.parse(JSON.stringify(this.stageData[idx]));
                }
            }
            return null;
        }
    }
}

module.exports = new DataMgr();

使用如下：

    onLoad: function () {
        DataMgr.getInstance().loadAllDatas();
    },

    onLoad: function () {
        DataMgr.getInstance().getStageDataByID(1).enemy_group;
    },

    onLoad: function () {
        DataMgr.getInstance().stageData[1].trajectorys;
    },

其他使用：

var DataMgr = require ("./data/DataMgr")
var Global = require("Global")
cc.Class({
    extends: cc.Component,

    properties: {
       
    },

    onLoad: function () {
        DataMgr.getInstance().loadAllDatas();
        
		this.stageName = cc.find('center/Label_stageName');
        this.stageName.getComponent(cc.Label).string = DataMgr.getInstance().getStageDataByID(Global.curStageID).stage_name;
    },

    update: function (dt) {
    },

});

其他使用（二）：

    onLoad: function () {
    	this.temp = new Array();
    	this.tempGroup = new Array()
    	this.Imformation = DataMgr.getInstance();
    	for (let i = 0; i < this.Imformation.stageData.length; i++) {
			this.temp = this.Imformation.stageData[i].trajectorys.split(",")
			this.tempGroup.push(this.temp)
		}
    },
