NICE

Mah god, this is EPIC!
And it works in the beta15!
For the speedometer and tachometer try using the bend feature in the hinges. Just go ahead and try dividing a var in the value bendTarget, until you get the effect you want. for the speedometer try making a var (in this case g1) and put in showBorder of any object that moves of the car ={Scene.my.g1 = vel (0);true}
This will make that scene.my.g1 is the horizontal velocity of the geometry, and will make showborder true also.
Then use g1 in the bendTarget part of the hinge of the gauge, and put it like this:
bendTarget = {{Scene.my.v1 / x}+y}
x is any number, just try until it works automagically, using that if the car goes very fast, the number should be bigger until it gives you a value lower than the max angle of the gauge.
And then y should be any number if the needle gets at 180º always and we want it at -135º.

And for the angVel it's the same!

I've kinda treated you like the epic noobiness, but well, use what you can from this! I hope you can understand me, if not, just ask. I can make you an example scene if you want.

haha! Thank's so much! means a lot coming from a veteran algodooer like yourself!

But um...well. I am kind of the epic noobness.
I've read your explanation over and over and tried applying what you wrote as I read it, but I'm still just stumped lol.
I'm sure it's easier than I'm making it out to be, but simple things like changing an objects color on collide seemed impossible to me only a few months ago.

Btw, as you can probably tell this is "the vehicle" that I said I was working on when you helped me with my engine.

Thanks again! I really appreciate all the help you've given me.

Wow! Nice job so far! Just get the scripting figured out, and you will have a lot more "power" in your Algodoo toolbox for creating future scenes! It may seem difficult and confusing at first, but after a while you won't want to create a scene again WITHOUT Thyme scripting! I rely heavily on Thyme scripting for nearly all of my own scenes because I'm so mechanically inept.

Keep those great scenes coming!

Yes I totally agree. I used to be forced to make everything mechanical because I knew nothing about thyme. you can tell by looking at some of my old scenes how I cut corners with mechanics. guess it was kind of my style though
