Hi

Is it possible, to send and receive single char via sf::packet? I'm trying to do this with simple code:


sf::Packet packet;
char test = 0x01;
packet << test;
//sending packet

Code: [Select]


sf::Packet packet;
//receiving packet
char test;
packet >> test;
if (test == 0x01) std::cout << "Correct";
else std::cout << "Wrong" << (int)test;

...but it's not work: test is alyways 0.

Is there any solution for this problem?
Thanks

If you put other types of data (float, string, ...), does it work?

Sending other types of data works, but sending char with (for example) string, doesn't work...

What about sf::Int8?

It works correctly, so my problem is solved, thanks.

Anyway, it's nice to know, why the char type didn't work...

That's weird because sf::Int8 is a typedef on char.

Oops, that's because I used sf::Uint8 instead of sf::Int8. So, unsigned char works, signed doesn't

I did some tests, and it works perfectly if you use a sf::Int8 on each side.

It doesn't work with char (which is ok), but the compiler informs you with a warning if it's proplery configured.
