我有一种感觉这是一个愚蠢的错误,但我正在制作回声服务器来识别数据包,并输出数据,然后重新发回它。它适用于某些数据包,但我试图回应的一个数据包正在崩溃,并说有一个堆被损坏。运行到与WinSock2应用程序堆腐败
Vector类,只是用集装箱现在:
PlayerData结构:
struct PlayerData
{
vec2 pos;
int health;
float rotation;
char moveflags;
short playerID;
};
包我想送:
struct ServerPacket_SyncGame //5
{
short packetID;
PlayerData data[8];
};
接下来的部分是凌乱,但我会评论它尝试是有道理的。
ServerPacket_SyncGame* SP_SG = new ServerPacket_SyncGame; //creates packet pointer
for(int i = 0; i < 8; i++) //assigns the eight playerdata structs in the packet array
{
SP_SG->data[i].playerID = i;
SP_SG->data[i].health = rand() % 30;
SP_SG->data[i].moveflags = 'D';
SP_SG->data[i].pos.x = rand() % 1000;
SP_SG->data[i].pos.y = rand() % 1000;
SP_SG->data[i].rotation = rand() % 360;
}
SP_SG->packetID = 5; //assigns the packet id
cout << "\n\nSent data: \n"; ////Outputting the data to be sent
for(int i = 0; i < 8; i++)
cout << "\nPlayer ID: " << SP_SG->data[i].playerID << "\nPosition: ("
<< SP_SG->data[i].pos.x << ", " << SP_SG->data[i].pos.y
<< ")\nHealth: " << SP_SG->data[i].health << "\nRotation: "
<<SP_SG->data[i].rotation << "\nMove Flags: "
<< SP_SG->data[i].moveflags << endl;
void* SP_SG_DAT = (void*)SP_SG; //casting the packet into a void*
char* SP_SG_BUFF = (char*)SP_SG_DAT; //casting from a void* to a char*
send(Socket, SP_SG_BUFF, sizeof(ServerPacket_SyncGame), 0); //sends the char*
char* SP_SG_RCVBUFF = new char; //new buffer for recv
recv(Socket, SP_SG_RCVBUFF, sizeof(ServerPacket_SyncGame), 0); //recv new buffer
void* SP_SG_RCVDAT = (void*) SP_SG_RCVBUFF; //casts char* to void* again
ServerPacket_SyncGame* RCVSP_SG = (ServerPacket_SyncGame*) SP_SG_RCVDAT;
//casts from void* to packet*
cout << "\n\nRecieved Data:\n\n"; //outputs converted received information
for(int i = 0; i < 8; i++)
cout << "\nPlayer ID: " << SP_SG->data[i].playerID << "\nPosition: ("
<< SP_SG->data[i].pos.x << ", " << SP_SG->data[i].pos.y
<< ")\nHealth: " << SP_SG->data[i].health << "\nRotation: "
<<SP_SG->data[i].rotation << "\nMove Flags: "
<< SP_SG->data[i].moveflags << endl;
我用这个方法与其他数据包,它完美地工作,服务器端这是怎么了回声:
for(;;)
{
char* buffer = new char;
char* temp = new char;
int size = recv(Socket, buffer, sizeof(ServerPacket_SyncGame), 0);
memcpy(temp, buffer, size);
send(Socket, (char*)InterpretInfo((void*)temp), size, 0);
};
InterpretInfo接受你施放煤焦出无效* *您收到,它处理它是这样的:
void* InterpretInfo(void* data)
{
short* tempsht = static_cast<short*>(data);
cout << "\n\nRecieved packet ID: " << *tempsht;
switch(*tempsht)
{
这个特定包的ID是5,这是它的情况:
case 5:
//ServerPacket_SyncGame
{
cout << " which is ServerPacket_SyncGame\n";
ServerPacket_SyncGame* decoded = (ServerPacket_SyncGame*)data;
for(int i = 0; i < 8; i++)
{
cout << "Player ID: " << decoded->data[i].playerID ;
cout << "\nPosition: (" << decoded->data[i].pos.x << ", "
<< decoded->data[i].pos.y << ")\n";
cout << "Health: " << decoded->data[i].health
<< "\nRotation: " << decoded->data[i].rotation
<< "\nMove Flags: " << decoded->data[i].moveflags << endl;
}
return(void*)decoded;
}
它只对这个数据包起作用,当我尝试访问数据包中的任何内容时,它会中断并说堆已损坏,但在调试模式下,我可以清楚地读取数据包中的所有信息。
我至少需要10代表张贴图片,所以这里是我在运行的代码谈论的链接: http://i.imgur.com/Dbyi0c3.png
谢谢你在先进的任何帮助或洞察力,以帮助我完成这件事,我仍然是C++的新手,并且很喜欢学习。
非常感谢你,它现在有效。也谢谢你提出清理我的代码的建议!我真的需要他们。 –
