简介:
这个脚本(Ufun.js)
主要提供对libil2cpp中的方法解析,批量断点,函数调用,参数解析等等功能
- 函数地址查找
/**
* 根据 ImageName , ClassName , functionName , argsCount 找到对应 function 的地址
* 最后一个参数 isRealAddr 用作显示静态分析地址还是当前内存地址（带这个参数则只返回地址，不带则列表信息）
* find_method("UnityEngine.UI","Text","get_text",0)
* find_method("UnityEngine.UI","Text","get_text",0,false)
*/
function find_method(imageName,className,functionName,argsCount,isRealAddr)
[Pixel XL::XXX]-> find_method("UnityEngine.UI","Text","get_text",0,false)

-------------------------------------------------------------------------------------
- 列出所有的程序集及其class数量
（others：m()列出class下的方法，f()列出class下的字段，可以配合实例进行参数解析）
/**
* 根据 ImageName , ClassName , functionName , argsCount 找到对应 function 的地址
* 最后一个参数 isRealAddr 用作显示静态分析地址还是当前内存地址（带这个参数则只返回地址，不带则列表信息）
* i()
* i("Unity")
*/
function i(filter)

5.触发called function后可以使用b()去解析参数
使用listfieldsfrommethodinfo()解析该方法类实例的字段值
