使用mono構建c#指令碼執行環境
Unity引擎使用mono作為指令碼的執行環境,本文主要使用mono的internal call來進行c++與c#的互操作
1.資料格式
進行互操作是需要進行資料傳遞,這裡主要分為三類,原生型別,值型別,以及引用型別
1.1 原生型別
常用如下
c++ c# mono
int int int
float float int
char* string MonoString*
c#的string和MonoString*會在使用是自動轉換,所以需要進行MonoString* 與char*的轉換,這裡直接使用了stl的std::string.
std::string MonoStringToString(MonoString* monoString)
{
char* pStr = mono_string_to_utf8(monoString);
std::string str = pStr;
mono_free(pStr);
return str;
}
MonoString* StringToMonoString(std::string str)
{
MonoDomain* domain = mono_domain_get();
MonoString* monoString = mono_string_new(domain, str.c_str());
return monoString;
}
陣列物件分別是c++的陣列,c#的陣列,以及Mono的MnonoArray*
轉換如下
c++
template<class T>
MonoArray* VectorToMonoArray(std::vector<T*> vec, MonoClass* monoClass)
{
MonoArray* pMonoArr = NULL;
//MonoClass* pMonoClass = mono_object_get_class(T::getTypeNameStatic());
MonoDomain* pDomain = mono_domain_get();
MonoType* t = mono_class_get_type(monoClass);
size_t size = vec.size();
// - create a ubyte array
pMonoArr = mono_array_new(pDomain, monoClass, size);
if (NULL == pMonoArr)
{
return NULL;
}
// - convert string into mono string and add them to a mono byte array
for (uint32 ii = 0; ii<size; ii++)
{
MonoObject* tp = vec[ii]->getMonoObject(); //這裡已經繫結好了c#物件,具體程式碼往下看
mono_array_set(pMonoArr, MonoObject*, ii, tp);
}
return pMonoArr;
}
template<class T>
std::vector<T*> MonoArrayToVector(MonoArray* monoArray)
{
MonoObject* pStr = NULL;
size_t size = mono_array_length(monoArray);
std::vector<T*> arr;
for (uint32 ii = 0; ii<size; ii++)
{
pStr = mono_array_get(monoArray, MonoObject*, ii);
T* tmp = convert<T>(pStr);
arr.push_back(tmp);
}
return arr;
}
1.2 值型別
值型別是指在c#中使用struct進行定義的型別,和enum定義的型別。對於值型別,只需要在c++和c#中分別定義相應的成員變數即可,例如
c++
class Vector2
{
public:
float x,y;
};
c#
struct Vector2
{
public:
float x,y;
}
又或者
c++
enum Direction
{
front,back,left,right
};
c#
enum Direction
{
front,back,left,right
}
注意,這裡的順序需要保持一致。這裡要注意,自己定義的值型別不能作為繫結函式的返回值,否則會出現異常的錯誤。所以為了正確地從c++中獲取值,需要使用引用。例子如下
c++
void ICall_ClassA_getPosition(MonoObject* self,Vector2& pos)
{
...
}
c#
private extern static void ICall_ClassA_getPosition(ClassA self, out Vector2 pos);
1.3 引用型別
在mono中統一轉換為MonoObject*
2.環境初始化,繫結,呼叫,清理
// 設定搜尋路徑,主要用於搜尋mscorlib.dll
std::string MonoPath = "C:/Program Files (x86)/Mono";
std::string ManagedLibraryPath = "E:/TestAllRuntime/TestAllRuntime.dll";
std::string monoPath = MonoPath;
std::string monoLibPath = monoPath + "/lib";
std::string monoEtcPath = monoPath + "/etc";
mono_set_dirs(monoLibPath.c_str(),monoEtcPath.c_str());
// dll所在的位置
const char* managed_binary_path = ManagedLibraryPath.c_str();
//獲取應用域
domain = mono_jit_init("TestAllRuntime"); // TestAllRuntime可以隨意取
mono_config_parse(NULL);
//載入程式集ManagedLibrary.dll
MonoAssembly* assembly = mono_domain_assembly_open(domain, managed_binary_path);
image = mono_assembly_get_image(assembly);
// 註冊函式,這裡是以後主要新增的地方 ,所有的函式都是通過該方法繫結的
// TestAllRuntime 是c#中ClassA的namespace
// ClassA 是 類的名稱
// ClassA_bind 是c#中需要繫結的方法
// &ClassA_bind 的ClassA_bind 是c++中需要繫結的方法
mono_add_internal_call("TestAllRuntime.ClassA::ClassA_bind",
reinterpret_cast<void*>(&ClassA_bind));
MonoClass* main_class = mono_class_from_name(image, "TestAllRuntime", "Main");
const bool include_namespace = true; //是否包含名稱空間
MonoMethodDesc* managed_method_desc = mono_method_desc_new("TestAllRuntime.Main:main()", include_namespace);
MonoMethod* managed_method = mono_method_desc_search_in_class(managed_method_desc, main_class);
mono_method_desc_free(managed_method_desc);
//呼叫剛才獲取的TestAllRuntime.Main:main(),第二個引數為NULL,表示呼叫靜態函式。如果函式不是靜態的,那麼就需要傳相應的MonoObject
mono_runtime_invoke(managed_method, NULL, NULL, NULL);
//清理mono環境
mono_jit_cleanup(domain);
主要的執行流程如上述程式碼所示
3.實現指令碼功能
為了實現指令碼功能,需要在c++中持有c#物件的handle,再通過handle就可以獲得相應的c#物件。在c#中也需要持有c++物件的pointer。為了更快地從c#物件中獲取c++物件的指標,可以通過記憶體地址偏移來獲得,具體實現如下。這裡參考的是Genesis3d引擎中如何進行繫結的。程式碼如下
c#
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;
namespace TestAllRuntime
{
[StructLayout(LayoutKind.Sequential)]
public abstract class Base
{
private IntPtr cppPointer; //會在c++中直接通過偏移獲取該欄位
}
}
這裡先定義一個Base的虛基類,並使用[StructLayout(LayoutKind.Sequential)]來保證IntPtr在記憶體中的位置,具體的解釋可以百度或谷歌。其他所有的類都繼承Base。
在c++中就可以使用如下程式碼獲取c#儲存的 c++ pointer
c++
struct DataOnHead
{
void* _cppObjectPtr;
};
static const int MonoObjectMemoryOffset = sizeof(void*) * 2;
DataOnHead* getDataOnHead(MonoObject* monoObject)
{
return reinterpret_cast<DataOnHead*> (((char*)monoObject) + MonoObjectMemoryOffset);
}
template<class T>
T* getCppFromMono(MonoObject* monoObject)
{
return static_cast<T*>(getDataOnHead(monoObject)->_cppObjectPtr);
}
void bindCppToMono(void* cppPtr, MonoObject* monoObject)
{
getDataOnHead(monoObject)->_cppObjectPtr = cppPtr;
}
template<class T>
void bindMonoToCpp(MonoObject* monoObject, T* cppPtr)
{
cppPtr->setMonoObject(monoObject);
}
template<class T>
void bindCppAndMono(MonoObject* monoObject, T* cppPtr)
{
bindCppToMono(cppPtr, monoObject);
bindMonoToCpp(monoObject, cppPtr);
}
這裡MonoObjectMemoryOffset為什麼是sizeof(void*)*2 可以從原始碼中或者api文件中看到
typedef struct {
MonoVTable *vtable;
MonoThreadsSync *synchronisation;
} MonoObject;
現在已經可以方便的獲得c#的cppPointer了,那麼同樣,在c++中可以定義變數和函式來儲存c#物件的handle,程式碼如下
c++
typedef unsigned int uint32;
const uint32 c_iInvalidMonoRefID = 0;
class ScriptDetail
{
public:
/// constructor
ScriptDetail()
: m_iMonoRefID(c_iInvalidMonoRefID)
//, m_pScriptObj( NULL )
{}
ScriptDetail::~ScriptDetail()
{
if (c_iInvalidMonoRefID != m_iMonoRefID)
{
m_iMonoRefID = c_iInvalidMonoRefID;
}
}
void ScriptDetail::SetMonoObject(MonoObject* pObj)
{
if (NULL != pObj)
{
if (m_iMonoRefID != c_iInvalidMonoRefID)
{
mono_gchandle_free(m_iMonoRefID);
m_iMonoRefID = c_iInvalidMonoRefID;
}
// - the second param should be 0, means this handle will not resurrection when invkoing finalisers.
m_iMonoRefID = mono_gchandle_new_weakref(pObj, 0);
}
else
{
// - must be set before
std::cout << "ScriptDetail::SetMonoObject,Deadly error!this prarm can't be null!\n" << std::endl;
}
}
/// Get m_pScriptObj
MonoObject* GetMonoObject(void);
/// to see if this cpp object is binding a mono object
bool IsBindMonoObject(void);
private:
// - do not allow copy
ScriptDetail(const ScriptDetail&);
ScriptDetail& operator=(const ScriptDetail&);
// - private data
uint32 m_iMonoRefID;
};
// - inline function implement ---
//------------------------------------------------------------------------
inline MonoObject* ScriptDetail::GetMonoObject(void)
{
return mono_gchandle_get_target(m_iMonoRefID);
}
inline bool ScriptDetail::IsBindMonoObject(void)
{
if(c_iInvalidMonoRefID == m_iMonoRefID)
{
return false;
}
return (NULL != mono_gchandle_get_target(m_iMonoRefID));
}
// - bind
#define __ScriptBind \
public:\
void setMonoObject( MonoObject* pObj ) { this->m_ScriptDetail.SetMonoObject( pObj ); }\
MonoObject* getMonoObject( void ) { return this->m_ScriptDetail.GetMonoObject(); }\
bool isBindMonoObject( void ) { return this->m_ScriptDetail.IsBindMonoObject(); }\
private:\
ScriptDetail m_ScriptDetail;
class ClassA
{
__ScriptBind;
...
};
在類的定義中新增__ScriptBind就可以了,程式碼也很簡單。m_ScriptDetail中初始化時為0,而正確的handle一定大於0,所以根據它來判斷是否已經綁定了相應的c#物件。
主要的思想就是這樣,剩下的就是定義相應的類,並把需要繫結的函式從類中提出來,再mono_add_internal_call,
然後在c#中定義相應的類和相應的函式。
例如
c++
void ICall_ClassA_createCpp(MonoObject* obj)
{
ClassA* t = new ClassA();
bindCppAndMono<ClassA>(obj,t); //繫結
}
void ICall_ClassA_setValue(MonoObject* obj,int value)
{
ClassA* tmp = getCppFromMono<ClassA>(obj);
tmp->setValue(value);
}
mono_add_internal_call("Test.ClassA::ICall_ClassA_setValue", &ICall_ClassA_setValue);
mono_add_internal_call("Test.ClassA::ICall_ClassA_createCpp", &ICall_ClassA_createCpp);
c#
using System.Runtime.CompilerServices;
class ClassA : Base
{
public ClassA()
{
ICall_ClassA_createCpp(this);
}
public void setValue(int value)
{
ICall_ClassA_setValue(this,value);
}
[MethodImplAttribute(MethodImplOptions.InternalCall)]
private extern static void ICall_ClassA_createCpp(ClassA self);
[MethodImplAttribute(MethodImplOptions.InternalCall)]
private extern static void ICall_ClassA_setValue(ClassA self, int value)
}
注意:新增[MethodImplAttribute(MethodImplOptions.InternalCall)] ,並注意 extern static 。
這裡使用static的目的是更直觀。
注意:為了在c#物件初始化的時候就初始化它的cppPointer,需要在它的建構函式中呼叫相應的函式來初始化
