idea for a new game mode: CatchTheTee (CTT)
  • one tee trying to escape the others, let's call this tee a rabbit
  • one or more tees trying to catch the rabbit, let's call them wolves
  • to win as wolves, you have to hit the rabbit with a hammer
  • to win as a rabbit, you have to avoid the wolves and reach a certain point on the map
  • wolves are delayed at start by a few seconds
  • rabbit can be chosen randomly at round begin
  • some special maps are needed probably what do you think?

You should always just recv everything you get, not like discarding the rest of the rx queue is cheap, nor can you know how much of the ex queue to discard without recving

the token is indeed big endian
Avatar
Ryozuki 2021-01-24 18:36:33Z
i was reading that for 4 hours
18:36
it doesnt say the response token is big endian
18:36
token must be the token from the request. If the server info isn't sent upon a request, it mut be -1.
18:37
token is an arbitrary byte chosen by the client which will be sent back with the server info. For the extended server info, the extra_token field needs to be included in the server info response.

Learath2 2021-01-24 18:37:17Z
token is a single byte, there is no byte order in single bytes 😛

extra_token is big endian

Patiga 2021-01-24 18:38:08Z
extra_token contains a 16 bit big-endian integer that should be shifted by 8 to the left and combined with token
i think this should give it away

Learath2 2021-01-24 18:38:11Z
extra_token << 8 | token is the token you are sent back

Avatar
Learath2 2021-01-24 18:52:19Z
Well a lot of code in teeworlds (incorrectly btw) assumes the host is little endian
18:52
but network byte order is usually big endian, so when reassembling the integer you essentially swap around the bytes
18:53
but C abstracts that away for you by defining bitshifts the way it does

can u send the link to the line
18:53
where it does it
Avatar
Learath2 2021-01-24 18:54:15Z
so you only need to remember where you put things, when crafting the request, we generate a 3 byte token. The least significant byte we put in the last byte named token in the protocol

18:55
The most significant byte we put in the first byte of the extra token, the middle byte we put in the second byte
18:56
so overall the token is extra_token[0] << 16 | extra_token[1] << 8 | token
18:57
