I am trying to figure out a way to allow elastic 'joints' to shift over time in terms of position and strength, any suggestions on how to do that?

Here's the effect (though in 3d) that I am looking for. An elastic group getting pummeled by other objects and changing shape.

Also another fun LFJS example:

Again, not VST, but this was interesting to me and could probably be integrated into C3 via JS integration.

Squishy Octo fun with LFJS.

Having fun with this and I know I have only scratched the surface! Using iPhone accelerometer to control gravity (tilting phone) and use an image to particle spawn, elastic behavior makes for a nice effect. I can see creating an image specifically for this could turn out really well.

It's not as direct as your example, but perhaps something with

CreateDynamicTexture(width, height, opts)

and

UpdateTexture(data, texture, opts)

Another option is to try out a JS QR library and use C3 JS integration to add it to your project.

For example:

github.com/nimiq/qr-scanner
One caution on mobile. Last I checked, iOS (as of 13.2) does not support user-media (web camera) when using webkit (e.g. iOS app or PWA.) The Apple team claims to be 'working on it.'

It should work with Desktop Chrome, Safari on iOS and Android.

Great post - well done TheRealDannyyy and Armaldio!

A few comments on my Greenworks plugin (Greengrinds.) It's free, it's an extension of the official C3 plugin. It works with nw.js and Electron (using Armaldio's Electron For Construct.)

I added ACEs for the following Greenworks APIs: Cloud File, more Achievements, Stats, and DLC. It's also C3 only.

For basics, see:

partner.steamgames.com/doc/gettingstarted
It does not need to be one binary. You can upload directories (such as an nw.js directory.)

I usually follow this tutorial series when I need a refresh:

youtube.com/watch
This is mainly how to get your content up to Steam and publish it (but not all the marketing, biz and partner details.)

Also, you can use one of the C3 Greenworks plugins to do achievements, etc.

(Construct Official)

or

construct.net/en/make-games/addons/244/greengrinds
(I extended the above plugin to add more Greenworks commands and it is also compatible with Electron build.)

Check out this (it has many limitations, but if the fates allow, maybe it will work for you :) )

It depends on render order, so if you place it on a certain layer it will copy everything under that layer (rendered before it.)

Example of denorm and clamping.
