The Tween Machine

Welcome to The Tween Machine, an interpolation toolbar plugin forAseprite v1.2.40 or higher. (Including 1.3 betas + stable)

 Originally requested by WhiteVault, this tool creates in-between frames of animation within sets of keyframes.

Check out this funny clip from the man himself if you're not compleatly sold here xD Whitevaults Sales Pitch 

Also quick shoutout to Clockwork Raven for their amazing sprites as I am using them in the below examples!

This tool supports motion interpolation featuring position, scale and rotation. All of which can be used individually or  together in a single action.

Position Tween / Interpolation:

Scale Tween / Interpolation:

Scaling can also be done non uniformly too! Very easy squish and stretch :D

Note: Sometimes position may need to be checked when scaling if it doesn't quite look right.

*NEW in v1.1.0* Interpolation Off Canvas

This will allow you to quickly expand and retract your canvas so you can tween outside the scene!

It even works going off and coming back on too!

Rotation Tween / Interpolation:

Modify Existing Cels :

The tween machine can also tween  layers that have animations already, such as this walking fox from Ansimuz.

Multi Tween Support:

Also supported with this tool is creating multiple tweens in one step. Simply select a or more sets of keyframes and your tween settings will be applied to each set of keyframes.

This tool also has support for image interpolation modifies existing frames instead of creating them. Image interpolation includes Hue, Saturation, Value, and Alpha. Each can be used together as well in a single action.

Hue Tween / Interpolation:

Fade In / Fade Out (Create In Reverse):

This option can be toggled if you want to tween in or out. Also note that if your first and last frame are the same using a position tween will simply fill in all cels in between so they can be modified.

Easing Methods:

Want your interpolation to feel less like a robot, moving at a constant speed? The tool has built in Easing Methods which will give you a better, smoother, and more natural feeling animation.

Linear- Like a robot, one constant speed from one keyframe to the next.

EaseIn- Picture a rocket starting slow and gradually getting up to speed.

EaseOut- Falling fast but gradually slowing to a stop at the end of the keyframe.

EaseInOut- Motion like a car, starting slow gradually getting up to speed and then slowing gradually to a stop.

Again shoutout to Ansimuz for this awesome little fox character.
