爲什麼不更新kbe warring的代碼解讀了，因爲在我看來那個demo講完了實體就沒東西可講了，如果專心的看官方文檔和PPT的話demo的代碼後面沒任何難點了已經，單純的複製黏貼代碼實在太過無聊。程序員一定要做點好玩的事情才行~
好吧，今天開始想法直接改引擎底層，爭取把引擎底層直接玩壞(*^__^*)
另外因爲平時工作比較忙，這個系列會不定期的更新。
從自己的HelloWorld寫起
先來點簡單的，baseapp腳本層調用一個自定義的C++函數，輸出helloworld!
因爲是baseapp的特有C++函數，所以我們需要打開baseapp項目的文件進行修改，這裏我選baseapp.h和baseapp.cpp
爲避免複製黏貼多餘的代碼，所以只寫核心部分
baseapp.h
class Baseapp : public EntityApp<Base>,
public Singleton<Baseapp>
{
public:
//added by lsm
static PyObject* __py_findAvatarByName(PyObject* self, PyObject* args);
protected:
}
baseapp.cpp
//-------------------------------------------------------------------------------------
bool Baseapp::installPyModules()
{
Base::installScript(getScript().getModule());
Proxy::installScript(getScript().getModule());
GlobalDataClient::installScript(getScript().getModule());
registerScript(Base::getScriptType());
registerScript(Proxy::getScriptType());
// 將app標記註冊到腳本
std::map<uint32, std::string> flagsmaps = createAppFlagsMaps();
std::map<uint32, std::string>::iterator fiter = flagsmaps.begin();
for (; fiter != flagsmaps.end(); ++fiter)
{
if (PyModule_AddIntConstant(getScript().getModule(), fiter->second.c_str(), fiter->first))
{
ERROR_MSG(fmt::format("Baseapp::onInstallPyModules: Unable to set KBEngine.{}.\n", fiter->second));
}
}
// 註冊創建entity的方法到py
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), time, __py_gametime, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), createBase, __py_createBase, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), createBaseLocally, __py_createBase, METH_VARARGS, 0);

APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), createBaseAnywhere, __py_createBaseAnywhere, METH_VARARGS, 0);

APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), executeRawDatabaseCommand, __py_executeRawDatabaseCommand, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), quantumPassedPercent, __py_quantumPassedPercent, METH_VARARGS, 0);

APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), deregisterReadFileDescriptor, PyFileDescriptor::__py_deregisterReadFileDescriptor, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), deregisterWriteFileDescriptor, PyFileDescriptor::__py_deregisterWriteFileDescriptor, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), reloadScript, __py_reloadScript, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), isShuttingDown, __py_isShuttingDown, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), address, __py_address, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), deleteBaseByDBID, __py_deleteBaseByDBID, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), lookUpBaseByDBID, __py_lookUpBaseByDBID, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), setAppFlags, __py_setFlags, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), getAppFlags, __py_getFlags, METH_VARARGS, 0);
//addition by lsm
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), testfunc, __py_findAvatarByName, METH_VARARGS, 0);
return EntityApp<Base>::installPyModules();
}
//added by lsm
//Email:[email protected]
//Description:某些自用的函數
//-------------------------------------------------------------------------------------
PyObject* Baseapp::__py_findAvatarByName(PyObject* self, PyObject* args)
{
PyObject* pyval = NULL;
std::string strTest = "HelloWorld!This is my first test cpp function!!--Lsm";
pyval = PyUnicode_FromString(strTest.c_str());
return pyval;
}
然後我們就能用官方自帶的調試工具驗證我們的成果了~！
輸出某類實體
一般來說，C++效率是python的50-1000倍，所以如果遇到比較耗時的操作我們需要放到C++部分進行運算。另外引擎自己提供的api有些時候不能滿足我們自己的需求，這個時候就需要我們來實現自己的需求了。
寫點稍微有用的，kbe自帶的api沒有辦法直接輸出某類實體，那麼我們製作一個自己的api,輸出某類實體。
和上個方法類似，首先頭文件定義
Baseapp.h
class Baseapp : public EntityApp<Base>,
public Singleton<Baseapp>
{
public:
//added by lsm
static PyObject* __py_testfunc(PyObject* self, PyObject* args);
static PyObject* __py_findEntityByName(PyObject* self, PyObject* args);
protected:
}
Baseapp.cpp
//-------------------------------------------------------------------------------------
bool Baseapp::installPyModules()
{
Base::installScript(getScript().getModule());
Proxy::installScript(getScript().getModule());
GlobalDataClient::installScript(getScript().getModule());
registerScript(Base::getScriptType());
registerScript(Proxy::getScriptType());
// 將app標記註冊到腳本
std::map<uint32, std::string> flagsmaps = createAppFlagsMaps();
std::map<uint32, std::string>::iterator fiter = flagsmaps.begin();
for (; fiter != flagsmaps.end(); ++fiter)
{
if (PyModule_AddIntConstant(getScript().getModule(), fiter->second.c_str(), fiter->first))
{
ERROR_MSG(fmt::format("Baseapp::onInstallPyModules: Unable to set KBEngine.{}.\n", fiter->second));
}
}
// 註冊創建entity的方法到py
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), time, __py_gametime, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), createBase, __py_createBase, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), createBaseLocally, __py_createBase, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), createEntity, __py_createBase, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), createBaseAnywhere, __py_createBaseAnywhere, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), createBaseRemotely, __py_createBaseRemotely, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), createBaseFromDBID, __py_createBaseFromDBID, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), createBaseAnywhereFromDBID, __py_createBaseAnywhereFromDBID, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), createBaseRemotelyFromDBID, __py_createBaseRemotelyFromDBID, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), executeRawDatabaseCommand, __py_executeRawDatabaseCommand, METH_VARARGS, 0);

APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), charge, __py_charge, METH_VARARGS, 0);

APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), registerWriteFileDescriptor, PyFileDescriptor::__py_registerWriteFileDescriptor, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), deregisterReadFileDescriptor, PyFileDescriptor::__py_deregisterReadFileDescriptor, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), deregisterWriteFileDescriptor, PyFileDescriptor::__py_deregisterWriteFileDescriptor, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), reloadScript, __py_reloadScript, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), isShuttingDown, __py_isShuttingDown, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), address, __py_address, METH_VARARGS, 0);

APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), setAppFlags, __py_setFlags, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), getAppFlags, __py_getFlags, METH_VARARGS, 0);
//addition by lsm
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), testfunc, __py_testfunc, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), findEntityByName, __py_findEntityByName, METH_VARARGS, 0);
return EntityApp<Base>::installPyModules();
}
下面是方法的具體實現
PyObject* Baseapp::__py_findEntityByName(PyObject* self, PyObject* args)
{
//首先讀取參數
int argCount = (int)PyTuple_Size(args);
if (argCount != 1)
{
PyErr_Format(PyExc_TypeError, "KBEngine::findEntityByName(): args is error!");
PyErr_PrintEx(0);
return 0;
}
char* entity_name = NULL;
if (PyArg_ParseTuple(args, "s", &entity_name) == -1)
{
PyErr_Format(PyExc_TypeError, "KBEngine::findEntityByName(): args is error!");
PyErr_PrintEx(0);
return 0;
}
//獲取實體列表
Entities<Base>::ENTITYS_MAP& entities = Baseapp::getSingletonPtr()->pEntities()->getEntities();
Entities<Base>::ENTITYS_MAP::const_iterator iter = entities.begin();
//先遍歷獲取返回值大小
int entity_size = 0;
while (iter != entities.end())
{
PyObject* entity = static_cast<PyObject*>(iter->second.get());
//如果名字和實體名相同
if (strcmp(entity->ob_type->tp_name, entity_name) == 0) {
entity_size++;
}
iter++;
}
//第二次遍歷獲取具體返回值
iter = entities.begin();
PyObject* pyList = PyList_New(entity_size);
int i = 0;
while (iter != entities.end())
{
PyObject * pTuple = PyTuple_New(2);
PyObject* entityID = PyLong_FromLong(iter->first);
PyObject* entity = static_cast<PyObject*>(iter->second.get());
//如果名字和實體名相同
if (strcmp(entity->ob_type->tp_name, entity_name) == 0) {
Py_INCREF(entity);
PyTuple_SET_ITEM(pTuple, 0, entityID);
PyTuple_SET_ITEM(pTuple, 1, entity);
PyList_SET_ITEM(pyList, i, pTuple);
i++;
}
iter++;
}
return pyList;
}
最終效果如下圖
