C# asynchronous tasks? Possible? Supported?

[nyolc8 215]

Hello all, I'm asking if asynchronous tasks are possible in GTA4 scripthook? Is it supported?

[nyolc8 215]

Is there a trick or way to run multiple tasks somehow? The methods I tried just made my game hang when the asynchronous method got started (screen frozen into a static image, sound stopped).

Certain things you can't do asynchronously as they (as you've noticed) make the game hang. I'm using ScriptHook .Net and I try to avoid anything involving GTA.Script, GTA.Game, GTA.World, or GTA.Native Classes.

 

Usually fairly easy to work around, however. Haven't had any issues using anything in GTA.Ped or GTA.Vehicle classes, but GTA.Script.Exists() and GTA.Game.Exists() make the game hang, of course, so you'll have to check for existence some other way.

whatever you need to do with GTA you do in your script, anything else can run in another thread which can set flags that tell your script what to do... you can muti thread just have to use threads to tell your script what to do... as long as you dont use waits in your script then it can respond accordingly in a tick

I tried making multithread in c# (VS 2013 community edition) but it just doesn't work. Can you show an example for this? Because I read multiple solutions and commands to achive this but none of them worked for me.

System.Threading.Thread thread = new System.Threading.Thread(() =>                {                });            thread.IsBackground = true;            thread.Start();

?

Thanks, I didn't tried this, I'll look into it

[nyolc8 215]

 

System.Threading.Thread thread = new System.Threading.Thread(() =>                {                });            thread.IsBackground = true;            thread.Start();

 

So I tried this, and got an "error in script" message, then the script stopped for a few seconds (I think while the wait() command paused it), then the game got hang.

 

Can I use "Wait(XX);" in the new thread? (that would be the whole point for me in this multithreading question)

 

edit: yes, the game hangs after the wait command, and when it should continue.

 

edit2: used "Thread.Sleep();" instead of "Wait();" and looks like it works nicely.

Yeah you have to use Thread.Sleep

You can also use Tasks, https://msdn.microsoft.com/en-us/library/system.threading.tasks.task%28v=vs.110%29.aspx.

I've used them multiple times, mostly for HTTP GET/POST in the backgrounds, but they also work with the ScriptHook.NET functions.
