Raknet send and receive struct

[ParaToxic]

Hello community,

first big thank to Engineer Ken for the good Raknet tutorial.

 

I would like to send an receive a little struct with the position and the rotation of an entity.

 

I made it like this to send :

struct Player
{
float a,b;
};
//.......

Player pl;
pl.a = 12.0f;
pl.b = 4.5f;
//......
server->server->Send(reinterpret_cast<char*>(&pl),sizeof(pl), HIGH_PRIORITY, RELIABLE_ORDERED, 0, RakNet::UNASSIGNED_SYSTEM_ADDRESS, true);

 

For the client i don't know how to convert the client->p->data to a created "Player" struct like pl2.

 

Maybe somebody can tell me how to do that.

Thanks ;D

Are you doing this in 2D? You only have a and b. I would expect 2 x, y, z for position and rotation. Given you really need x, y, z use BitStreams. In fact use BitStreams no matter what. It's what's recommended. It also has WriteVector() and ReadVector() function build into it to write x, y, z and read x, y, z values.

I sent my structure successfully when I copy the client to an other PC in at my home it can't connect.

In the Client properties I have my IP which is listed by the server under IP adresses at place 1.

 

Maybe somebody can tell me why?

 

I think the problem is the Socket IP,which is 127.0.0.1 ,so localhost.How can I solve that?

 

Thanks and good night ;D

Hi Para Toxic,

 

I would highly reccomend sending BitStreams instead of Structs. I don't think I ever send structs at all.

 

If the IP u are using to connect is 127.0.0.1 then you are networking with yourself. If you are trying to network between 2 computers you need to determine the semi-dynamic IP of the server computer (something like 192.168.x.x)and connect to that instead. If you want over the internet you need the fully dynamic IP. Some day I will write a tutorial on how to to do LAN server discovery so you don't have to hard code the IP addresses but that is for another day. In the meantime you can look at the example LAN server discovery code that comes with RakNet.
