I got a packet like this:
[sf::Uint8][sf::Uint32][std::string][rest..]
now i want to make a new packet which has only sf::Uint8 and rest. How do i do that using append?(the problem is std::string..)

sf::Packet is made for packing data and sending it. You're not supposed to do anything else with it, you should construct it right before sending to the socket with the final data.

What do you need to do that?

I get packet from client [sf::Uint8 type ][sf::Uint32 id ][std::string lobbyname ][rest]

i want to send from server packet without id and lobbyname, only packet type and the rest.

Construct a new packet with only type and rest, and ignore id and lobbyname?

The overloaded operators << and >> will help you at this task.

yeah dude but all data is IN the packet. to get the rest i need the starting pointer of rest. To do that i need to know what is the size of [sf::Uint8 type ][sf::Uint32 id ][std::string lobbyname ]

Extract everything, and send only the variables that you want.
