How do i avoid desync while making a rhythm game?

[Gaypatapon]

I'm making a patapon fangame but the beat desyncs, i tried using the timer but it still doesn't work, is there a way to make precise rhythm?

[supersonico]

I suggest using the DeltaTime extension

[softedco]

delta time isn't related to this

[Gaypatapon]

well then how do I avoid desync without needing to have 60 fps?

[supersonico]

delta time isn't related to this

DeltaTime is used in most rythm games to ensure a consistent speed and sync with the songs regardless of the frame rate, how is it not related to this?

[supersonico]

how do i do it then?

Well, there's multiple ways to use DeltaTime, I personally use this:

I'm sure your favorite browser can help you find more effective ways.

[Gaypatapon]

Ok cool, is there also a way to do this with timers?

[Gaypatapon]

like I don't want the beat to desync

If you mean using DeltaTime with the timer instead of the extension, yes:

I meant as in using the timer with the extention

because it is used in all decent games to ensure sync, if it's used in rhythm games it does not mean it is related to making rhythm sync, it is only related to making the whole project sync, and sync that is with only other framerates, not the music

I never said Delta Time was exclusively for rhythm games, I said rhythm games use it.
Of course DT is not only for the music, but the desync usually occurs because of inconsistent FPS, so using DeltaTime is one step closer to avoid desync.

[softedco]

It doesn't usually occur when you have a fixed framerate which is true for almost all games made in scratch and turbowarp

[supersonico]

Even if you set the framerate to a value like 30, 60, 250 (as TurboWarp allows you to do), it does not mean that the FPS will always be that, you just set the max FPS.

[softedco]

Oh, can you show me how to use deltatime for rhythm games?

the rhythm is like from patapon, i'm making a patapon fangame but the problem is that the beat doesn't match up the song

Again, I don't know how your game works nor do I want to know. I already showed you the basic script and an example, you should try to apply it to your scripts.

You didn't answer him on how to make music sync with gameplay, which is what he was asking in the first place.

[supersonico]

They were asking how to avoid desync in a rhythm game, read the title.

[softedco]

it's about beat desync, not game desync

[GarboMuffin]

Delta time isn't really meant to solve this. The best you're going to get is using "days since 2000" to get the most precise timer available in Scratch (multiply by 86400 to get seconds; you could also just use normal timer blocks). Record the start time and just calculate the current time in the song from that.

Instead of doing things like "move the note forward [x] pixels per frame" (will lead to imprecision), you would use some math to figure out exactly where each note is supposed to be displayed at the current time. That's the best you can get.

yep I use this method on my rhythm game
