5.3背包系统（1）
基类脚本
usingUnityEngine;
usingSystem.Collections;
publicclassBaseScript{
publicintindex;
publicfloatattackValue;
publicfloatHp;
publicstringname;
publicstringdescription;
publicstringiconName;
publicBaseScript(intindex,floatattackValue,floatHp,stringname,stringdescription,stringiconName){
this.index=index;
this.attackValue=attackValue;
this.Hp=Hp;
this.name=name;
this.description=description;
this.iconName=iconName;
}
}
物品子类脚本
usingUnityEngine;
usingSystem.Collections;
//武器类
publicclassWeaponScript:BaseScript{
publicWeaponScript(intindex,floatattackValue,floatHp,stringname,stringdescription,stringiconName):base(index,attackValue,Hp,name,description,iconName){

添加物品脚本（挂载在canvas）
usingUnityEngine;
usingSystem.Collections;
usingSystem.Collections.Generic;
usingUnityEngine.UI;
