Fiber confusion (SOLVED?)

[HezkoreParticipant]

I’m trying to make a new fiber/thread that keeps going in the background at all times in my game.
It updates some stuff much faster than the 60 FPS I render in the game.
But the fiber pauses the game, and I thought that was the whole point of fibers, to not pause the game?
I’m guessing I’m doing something wrong?

Here’s some test code, what am I doing wrong?
Press space to run a fiber and notice the text stops scrolling.

Monkey

#Import "<std>" #Import "<mojo>" Using std.. Using mojo.. Class MyWindow Extends Window Method New( title:String="Simple mojo app",width:Int=640,height:Int=480,flags:WindowFlags=Null ) Super.New( title,width,height,flags ) End Method OnRender( canvas:Canvas ) Override App.RequestRender() canvas.DrawText( "Hello World!",Width/2+Millisecs()*0.1 Mod 320,Height/2,.5,.5 ) If Keyboard.KeyHit(Key.Space) Then New Fiber(Lambda() Local i:Int While i<10 Print i i+=1 Sleep(0.1) Wend End) Endif End End Function Main() New AppInstance New MyWindow App.Run() End

#Import "<std>" #Import "<mojo>"   Using std.. Using mojo..   Class MyWindow Extends Window   Method New( title:String="Simple mojo app",width:Int=640,height:Int=480,flags:WindowFlags=Null ) Super.New( title,width,height,flags ) End   Method OnRender( canvas:Canvas ) Override App.RequestRender() canvas.DrawText( "Hello World!",Width/2+Millisecs()*0.1 Mod 320,Height/2,.5,.5 )   If Keyboard.KeyHit(Key.Space) Then New Fiber(Lambda() Local i:Int While i<10 Print i i+=1 Sleep(0.1) Wend End) Endif End End   Function Main() New AppInstance New MyWindow App.Run() End

UPDATE: It seems Fiber.Sleep() pauses the fiber, while Sleep() pauses the whole app!
I’m still wondering if I’m doing this correctly.

You are right – should to use Fiber.Sleep() inside of fiber to sleep it.

What are you wanna get at the end?

Monkey2 also has Timer and Future stuff, maybe you need one of them.

My game is a music game, so it has to update the music at all times in the background.
Correct timing of every note is important!
So I want a fiber running in the background taking care of all that while the game runs normally.

I’d like to never force the fiber to sleep, but if I don’t put it to sleep, the game still pauses.

From Mark’s blog…
http://monkey2.monkey-x.com/
“However, unlike real threads, fibers don’t run ‘in parallel’.”

 

I had tried also some stuff with fibers a while ago and I found that their usage is quite limited, but it’s very specific. From what I found in practical terms, fibers are more useful in event oriented applications (like Ted2Go) where you don’t want your application run in a 60fps loop but neither you want intense loops to freeze your user interface. For example if you have an intense loop, you can throw it in a thread, to let your main app – the gui mostly – be responsive.

 

 

Generally if your game runs at 60fps you won’t have any problems to use fibers, unless you want to do even more intense calculations (like lightmapping).
