samp-precise-timers ⌚
github.com/bmisiak/samp-precise-timers

Briefly
Developed for net4game.com (RolePlay), this SA-MP plugin provides precise timers for the server. It is written in Rust, a memory-safe language.

Why rewrite timers?
I had a lot of safety concerns with some of the existing solutions. They weren't written with data integrity, memory safety or preventing server crashes in mind and seemed to have quite a few bugs. As privacy and safety is our primary concern at net4game, I wrote this in Rust, which combines high-level ergonomics with the performance of a low-level language. ⚡

Please check out the code to see the benefits. You might like Rust a lot. The code is much simpler than C++ equivalents, especially the ones which still use *char, free() and delete[] instead of modern C++ idioms such as std::unique_ptr, but as Rust has no runtime, there is no overhead 😉

We would like your help! 💃
Oh, and if you enjoy working on servers, we are looking for a team to help our international expansion. 🎉 net4game has been around for a decade as the biggest Polish server. We introduced a lot of innovations over the years and we are almost ready to become international. Shoot me an e-mail at bm+code@net4game.com if you're interested.

Great respect for u polish developers for presenting such a unique plugin, as soon as reach my destination I might give a try, BTW great introduction of your release +rep:

[Chaprnks]

Do you know if this is compatible with y_timers?

Yeah, it is fully compatible with y_timers. The plugin defines two new natives:

Code:

/* 
    # SetPreciseTimer returns timer_number, or 0 on failure.
        interval: miliseconds before the callback is triggered.
        repeat:  true/false. If false, the callback will only be called once.

    # Examples:
    SetPreciseTimer("EveryMinute",60000,true);
    SetPreciseTimer("EverySecond",1000,true,"ds",playerid,"Hello");
    new array[2] = {42,2}; SetPreciseTimer("AfterFiveSecs",5000,false,"dsaA",playerid,"world",array,sizeof(array));
*/
native SetPreciseTimer(const callback_name[], const interval, const repeat, const types_of_arguments[]="", {Float,_}:...);

/* 
    Returns 1 if the timer existed or 0 on failure.
*/
native DeletePreciseTimer(const timer_number);

The argument syntax is compatible with SetTimerEx.

Thank you. I tried to make the code easy to understand. Give it a go, I would love to get some feedback 😊

I thought we were unable to pass strings through the settimer function, does that mean your plugin fixes it?

Fairly certain that you can pass a string as long as it is not empty. Kind of like CallRemote/LocalFunction.

Are you sure?

[MisterTickle]

Going to go ahead and implement this. Good job.

Ah.... just tested it and you would be correct. I just get random chars instead of the string i passed. I thought the issue was similar to the empty string issue. Guess not.

[Chaprnks]

I get this warning only when the timers plugin is enabled. Maybe SAMPGDK is out of date?

Hi everyone!
Thanks for the reports!

samp-precise-timers ⌚v2.0.2 release
This SA-MP plugin provides precise timers for the server. It is written in Rust, a memory-safe language.

Fix for `Native function not found`
As was discovered in issue #7, sampgdk (used by other plugins) makes certain assumptions about pointer lifetimes. This caused an incompatibility between samp-rs and sampgdk. The plugin now uses a newer samp-rs which contains a workaround, so using samp-precise-timers in tandem with certain other plugins will no longer cause `Native function not found` to appear.

CentOS 7 support
CentOS 7 ships with an old version of a library called `glibc`. The plugin will no longer depend on the newer version 2.18 and should now work just fine on CentOS.

EDIT: Evidentally not with it today; I'm going to try this!

[Fairuz]

So we just have to change SetTimer(also SetTimerEx) to SetPreciseTimer and KillTimer to DeletePreciseTimer?

Yes that simple

[Unrea1]

It would be better with these functions:

Code:

IsValidPreciseTimer
KillAllPreciceTimers

I've been using this plugin on my test server and I agree with the IsValid function, it is needed.

Hey, thanks for the suggestion. I could add it, but also, I would love to get a second contributor. If anyone is feeling like they'd like to give it a try and add it, hit me up! I'd love to help with any roadblocks you encounter. It will be very similar to the code for DeletePreciseTimer.

I tried to use this plugin on a test server however sometimes it doesn't call the functions, all the calls seem to stop randomly.
