@mileseven thanks for the feedback! Let see if this post catches the attention of the developer and he can share its view on this!

I think it would absolutely make sense to enable such capability, if it is not open already… it would certainly make SimHub even more applealing, I guess.

@gaelibus - not really. In the end, I’ve not experienced a meaningful overhead and so didn’t try to optimise it once I’d got the basics working. I’m still interested in a solution though as I’m thinking about further projects and they’re only ever likely to be increasingly complicated….

Hi, did you solve this issue?

It also looks to me that there should be a way to insert javascript functions in the javascript loop to support better coding and rendering efficiency. Possibly at overlay and/or dashboard levels...

I’m charging ahead with my first SimHub project to build a dash that analyses and presents tyre slip data under acceleration and braking in rf2.

I’ve adopted JavaScript for my calculations as I used to write VBA in a previous life.

Everything is working fine but I’m finding that I’m duplicating calculations and gamedata calls quite a lot - e.g. to drive a dial gauge to show tyre slip - but also using essentially the same calculations to drive a couple of calculated-colour overlays used as dial backgrounds. And then there are optional gauges/displays that compare left/right and front/back relative slip...

Soon adds up. I’m guessing the processing overhead is not too horrific compared to some complicated dashes - but for maintenance reasons alone, is there a way of creating/sharing functions (or calculated values) across multiple items in the same dash?

I noted the mention of variables in the GitHub simhub JS page but wasn’t sure if it addressed what I’m looking for....?
