@galoyo said in LAG: Syncing problems in Neko+Cpp Targets:

if after you optimize the code, there is still a delay in the speed of the game then you might give the option for the user to set the speed of the game by changing its framerate. this is not a bad idea as some users might like to play the game at a slower or faster framerate than others.

This^

Recently, a super nice youtuber willing to play my humble game stumbled upon this problem. Certain recording software can get the recording choppy, with uneven framerate, or slow to a crawl. We fixed this by adding an option to lock the game to 30 fps and enabling frameskip, with great results!

In case someone is wondering how that can be achieved, is simple:

FlxG.drawFramerate = 30; FlxG.updateFramerate = 30; FlxG.fixedTimestep = false;

BTW: sometimes is possible to have choppy, jumpy movement even tho you are having great performance. I can't yet understand why, but has something to do with super.update() call. For example, there might be sightly movement differences between this:

Update(elapsed) { movementCode(); super.update(elapsed) ; }

... and this:

Update(elapsed) { super.update(elapsed) ; movementCode(); }

Play test in game to see what gives you the best results!

@Gama11 How about the latest lime (5.3.0)..? If I install that then Flixel states:

Flixel is currently incompatible with Lime 3.0.0 or newer

Is there anyway we can ignore this and force a newer version of Lime instead of -3? I'm asking because i'm having some Jitter on camera follows again on a new project. Newer version of Lime just might have better SDL support and with that less Jitter. It seems to be a windows thing. I'm not seeing it on android.

There are a couple of discusion to be found with Google on this subject, but there does not seem to be a real solution.

Quote SruloArt here:

Try making vsync to only affect cpp (if="cpp" on your project.xml in the end of the relevant line) or cancel it altogether. Try FlxG.fixedTimestep = false; FlxG.maxElapsed = 0.25. Sadly, If these options won't work I wouldn't be too surprised.

A thread on github, an other one on google-groups, an interesting one on OpenFL (they talk about SLD there), and a post of myself. The problem just might not be Flixel or OpenFL, the problem can lay in Lime or SDL (or the way SDL is being used). Just playing around with stuff like:

FlxG.fixedTimeStamp, FlxG.maxElapsed, FlxObject.pixelPerfectPosition, FlxObject.pixelPerfectRender, Lerp and VSync.

Is time consuming and not fixing anything. I would love to try out a newer version of Lime, perhaps they fixed it there? :S Is it in anyways possible that i can try this? (Development version, beta version?)

I really like HaxeFlixel and enjoy using it. But this Jitter on camera while following is driving me insane! It does not happend at the beginning of the game, but after say 10 seconds it slowly starts, after that it builds up. After 2 minutes or so its very noticeable.

Does anyone have a solution for this?

Cool! Glad it could be worked out :)

@starry-abyss no worries! I actually have never released anything on HaxeFlixel with non-trivial performance requirements. I'm really grateful for the time and energy you put into explaining it to me until I finally "get it." So, thanks again.

I'll probably get a chance to work on this later tonight. I'll move my code into revive and if (for some reason) it doesn't work, I'll report back in this thread.

Thanks!

Yes, I remember the campaign, but if the project had more money, they could hire more people to work full time on it, run tests, improve the documentation, pay hosting costs, etc.
Well, I don't see a reason to not invest some more time improving the Patron page and I can't see how making more money wouldn't help HaxeFlixel.

Thanks. Looks like the vector trick will have to do for now. Still, I have to color every tile, so I might end up going with tinted FlxSprites drawn to a bitmap or something. I'll experiment.

@gcardozo that's an interesting link. The page right before that on FlxSprite answers my question:

It is pretty common place to extend FlxSprite for your own game's needs; for example a SpaceShip class may extend FlxSprite but could have additional variables for the game like shieldStrength or shieldPower.

Therefore, the main use-case of HaxeFlixel is inheritence-based, using the Flx* primitives as building-blocks.

For the record, I also created an ECS (actually, three) using HaxeFlixel. Ultimately, I moved away from this approach, because of a) duplication of fields across components (eg. synching the coordinates two-ways between a PositionComponent and the FlxSprite depending on if the user called move or if I'm using FlxSprite.velocity), and b) collision detection just didn't work reliably for some reason.

After moving away from using an ECS, I write less code and go faster, so I'm happy.

yooo, Hi u all! I was enslaved with studies these two weeks,I was a little absent, but im back, will have more action from now xD ...

Buenas!! estuve ausente un tiempo, estuve con presentaciones en la facu y me consumieron la vida, pero ya estoy de nuevo, y le voy a meter mas acción al foro/Haxe. Somos muchos con haxeflixel, yo hace 2 años empecé, pero ahora estoy retomando de verdad. Y que bueno ver UTNianos aca !! :P

It's a bit more more complex, but I once made a hexagon map by looping through the map like you would if you were inserting enemy/item sprites, but instead inserted hexagon-shaped FlxSprites. The trick is, every other row, you add an offset equal to half of the tile width.

I tried both. Honestly, HaxeFlixel is "better" IMO because:

You get a web/HTML5/Flash replacement. Silverlight is dead. You get native runtimes and really, really, really small apps. The default HaxeFlixel app for Android is like 3MB. With Monogame, ugh.

IMO, those are both really good reasons to favour HaxeFlixel over Monogame. Which is why I'm using HaxeFlixel...

Also be sure to email me after at lars.doucet@gmail.com so I don't forget!

hello
i'm new user.this forum is so beautiful.

Thanks Gama11

I'd love to help, but I don't have time now. Good luck, guys!
