为什么不更新kbe warring的代码解读了，因为在我看来那个demo讲完了实体就没东西可讲了，如果专心的看官方文档和PPT的话demo的代码后面没任何难点了已经，单纯的复制黏贴代码实在太过无聊。程序员一定要做点好玩的事情才行~
好吧，今天开始想法直接改引擎底层，争取把引擎底层直接玩坏(^__^)
另外因为平时工作比较忙，这个系列会不定期的更新。
从自己的HelloWorld写起
先来点简单的，baseapp脚本层调用一个自定义的C++函数，输出helloworld!
因为是baseapp的特有C++函数，所以我们需要打开baseapp项目的文件进行修改，这里我选baseapp.h和baseapp.cpp
为避免复制黏贴多余的代码，所以只写核心部分
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());
// 将app标记注册到脚本
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));
}
}
// 注册创建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(), quantumPassedPercent, __py_quantumPassedPercent, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), charge, __py_charge, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), registerReadFileDescriptor, PyFileDescriptor::__py_registerReadFileDescriptor, 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(), 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:240782361@qq.com
//Description:某些自用的函数
//-------------------------------------------------------------------------------------
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;
}
然后我们就能用官方自带的调试工具验证我们的成果了~！
输出某类实体
一般来说，C++效率是python的50-1000倍，所以如果遇到比较耗时的操作我们需要放到C++部分进行运算。另外引擎自己提供的api有些时候不能满足我们自己的需求，这个时候就需要我们来实现自己的需求了。
写点稍微有用的，kbe自带的api没有办法直接输出某类实体，那么我们制作一个自己的api,输出某类实体。
和上个方法类似，首先头文件定义
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());
// 将app标记注册到脚本
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));
}
}
// 注册创建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(), quantumPassedPercent, __py_quantumPassedPercent, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), charge, __py_charge, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), registerReadFileDescriptor, PyFileDescriptor::__py_registerReadFileDescriptor, 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(), 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_testfunc, METH_VARARGS, 0);
APPEND_SCRIPT_MODULE_METHOD(getScript().getModule(), findEntityByName, __py_findEntityByName, METH_VARARGS, 0);
return EntityApp<Base>::installPyModules();
}
下面是方法的具体实现
PyObject* Baseapp::__py_findEntityByName(PyObject* self, PyObject* args)
{
//首先读取参数
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;
}
//获取实体列表
Entities<Base>::ENTITYS_MAP& entities = Baseapp::getSingletonPtr()->pEntities()->getEntities();
Entities<Base>::ENTITYS_MAP::const_iterator iter = entities.begin();
//先遍历获取返回值大小
int entity_size = 0;
while (iter != entities.end())
{
PyObject* entity = static_cast<PyObject*>(iter->second.get());
//如果名字和实体名相同
if (strcmp(entity->ob_type->tp_name, entity_name) == 0) {
entity_size++;
}
iter++;
}
//第二次遍历获取具体返回值
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());
//如果名字和实体名相同
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;
}
最终效果如下图
