New Ease Bundle! - JR 01

The full Ease Bundle is out now with 10 Ease functions!



Alright Alright so for the past month, I’ve been trying to finish the old Ease Bundle project we made
(You can view the old post here: New Ease/Interpolation Behavior!).
But the Bundle only does Ease Sine Out, so I’ve been trying to find methods to create a new bundle with all the Ease functions (even more than Flowlab atm) and as well as making it easy to use the Ease In, Ease Out, and Ease In Out. After a little bit of help from @TinkerSmith and @grazer, I now have the perfected Ease Bundle that I’ve been wanting to make since @PixelPizza started the original project. I’ll be giving myself this birthday gift for everyone to enjoy.

So on with how this Beautiful Bundle works!

It may look complicated, but it’s actually fairly simple with some nice features!

  • Also note that I will mostly be describing the first behavior “Ease (Time)”
  • The “Ease Grid (Time)” works the same but with X and Y inputs (>Details).
  • The “Ease (Manual)” outputs the value equivalent to the % that was inputted (>Details).
  • (You must Always set From and To before using these Bundles)


  • Mode: Select what Ease type you want to use (this will be explained below)
  • Time: How many Seconds the Ease lasts (Decimals can be used as well)
  • From: Starting Value
  • To: Ending Value
  • Play: Starts or Resumes the Ease (this has to be use to trigger the Ease)
  • Pause: Stops the Ease and Keeps its values
  • Resets: Stops the Ease and Resets its values


  • Out: A new calculated value is outputted every frame until “Done” outputs.
  • Done: This outputs 1 when the easing has completed.

(Documentation based on the “Flowlab User guide: Ease behavior)


Modes are how you set the Ease types you want to use.
Modes are used in 2 digits (AB), where A = Formula and B = Type.

Digit A can used as:

  • 0 = Linear
  • 1 = Sine
  • 2 = Cubic
  • 3 = Quint
  • 4 = Circ
  • 5 = Elastic
  • 6 = Quad
  • 7 = Quart
  • 8 = Expo
  • 9 = Back
  • 10 = Bounce

Digit B can used as:

  • 1 = Ease In
  • 2 = Ease Out
  • 3 = Ease In Out

You must use Full Digits to set the Mode of the Bundle!

The Mode will not work with any other numbers, here are some examples:

  • Sine Ease Out = 12
  • Quad Ease Out = 62
  • Elastic Ease In = 51
  • Back Ease In Out = 93
  • Bounce Ease In = 101
  • Expo Ease In Out = 83
  • Linear = 0

Feel free to use it whenever you want!

You can use these bundles without crediting anyone, our examples are for free use!
Here are a few more details that could help understand how it works:

More Details:
  • Ease works by converting a complete percentage (0% -100%) into a formula that uses the From value and the To value to output the results.

  • The % is used like time in the equation, controlling how fast the % accelerates is also controlling the speed of the Ease Bundle (this is also why I made a “Manual” version).

  • Each formula uses Haxe coding in a expression block. All the coding was converted from into Haxe.

  • The numbers can be changed anytime, just make sure to input “Reset” and “Play” to fully use those values.

  • Reset is automatic when Done outputs. Reset does NOT change the values of From and To.

  • The “Ease Grid (Time)” is basically 2 of these Ease bundles put together. This makes it easier to move objects in Flowlab in one go by using the X and Y inputs. This also makes it possible to use a Time of 0 (instant) with correctly drawn lines.

If there are any issues, confusion, bugs, or help, then @JR_01 in your discussion.

I’ll probably keep adding to it with maybe some more Ease functions, maybe I could add a Time input for the example, but most likely I’ll keep fixing bugs and issues that come along. This was a big project, but I’m glad to get it out now. I hope everyone enjoys it!


It is done! At last! :tada:

This looks literally awesome! I can totally see al the work you put in this and I’m amazed, great work @JR01 and I hope this helps many people in need!


Nice job!


Awesome work, this looks really nice :slight_smile:


Quick update, a few small fixes to output the start and end values.
If you used the bundle before, I encourage you to use the updated version.


Version 4 is out now with cleaner and simplified code.
I implemented a custom router block that helps run the expressions that is needed only, as well as removing many filters when selecting a mode. This should help the bundle run better.

All the objects in this example was cleaned up too, easier to read and update.



And the bundles are found in this object in the editor instead of in every object:



niiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiice :upside_down_face:


Didn’t I briefly take part in this on the math end? I remember discussing this at one point. Either way that’s one hell of a bundle


You took part in the first project,
I scrapped it altogether and used the code from and converted it into Haxe to be used in the expression


Version 5 is out now, with 80% of all the code removed and replaced with a single expression by using over 150 lines of Haxe code by using that was pasted into the expression. The Pause input has also been removed and combined with the play input (input is shown as “Play//”). As well, I and Pizza are planning to redesign the example to show off each type and to show how to use the Bundle, so will have an update on that later.

Version 5:




Awesome! Thanks :slight_smile:
