Topic: use tick function in teeworld code

hey guys

i need a function that can repeat statements infinite,i guess i should use GameTick or other time variables  to do this but when  i use gametick in loops (while or for) this causes lag or game crash! i saw this function(tick) in lua file that is used in (n-client)
but i dont know how can i do this in teeworld source code.

Re: use tick function in teeworld code

Don't use while and for for that purpose. Put your code in some methods from your components (names are explicit) such as OnReset, OnRender, OnMessage...

Re: use tick function in teeworld code

Look in the code how to get the time. Look in components/hud.cpp for how the ingame clock is rendered for example smile

Re: use tick function in teeworld code

For Serverfiles, like Character, player, gamecontext... you can use

if(!(Server()->Tick()%Server()->TickSpeed()))
{}

now you can search for sth wit "Tickspeed" in client and copy it

Re: use tick function in teeworld code

Does Teeworlds use Mutex for multithreading?!

This is new to me.

Concerning the question: Teeworlds uses POSIX-Threads and the Windows-API
Atm also SDL semaphores are needed for Mac OS X, because unnamed semaphores aren't supported on OS X.
However you found the thread stuff in src/base/system.h/.c and atomics int src/base/tl/threading.h (NOTE: don't relay on the documentation in this header)

Re: use tick function in teeworld code

tnx BeaR
last week i read a document about multithreading,in one of part it said Windows does not support the pthreads standard natively!
now i use SDL for multithreading and it works fine wink

Where "fire" and "hook " events are defined?!

Re: use tick function in teeworld code

So let's clear this up a little:
Teeworlds DOES use threads - not much however.
They can be used via the thread_* functions of system.h, no further SDL dependencies necessary.

Where are threads used in Teeworlds:

  • graphics, with asyncrender enabled

  • sound loading, with threadsoundloading enabled (I would really recommend this, it's speeding up the startup heavily

  • master server lookup

The latter two are done via the engine's CEngineJob interface, which I would recommend looking into, nicely done by matricks. smile

Why not directly asking for the code for your bot?
