Wire Wheel

[BirdBlack]

I would like to see a wire controlled wheel with inputs that would allow you to use it like a servo.
Ideally, you would be able to tell it to turn x amount expressed in degrees, and be able to specify the direction of turn.
This would greatly help in the construction of turrets and mechs.

Isn't there already one in the latest revision?

Yeah, I already made a wired wheel. But as for making it work like a servo, that may be "beneath" source's physics abilities. You can only add torque to a motor, there is no "rotate to here" or "stop rotating". It's stupid, I know. Garry would have to add those functions. Unless someone can figure it out, which hasn't happened yet in all the "make a servo" request threads on FP, I doubt I will.

If you're looking to make a stationary servo, a quick solution can be to use a wired wheel, speedometer and gyroscope to assemble a feedback-based controlled rotation device. A comparison gate comparing speedo output with constant value can drive the wheel to ensure a relatively constant-angular-velocity turn, and then it's just a matter of determining direction and accuracy comparisons. We've used similar things for rotational radar, since the gyro can report back its absolute yaw as well.

I realize this doesn't create the tool you're looking for, but if you just need a solution for the meanwhile ...

It's close enough to get what I need done.

Thank you.

That's good cause to add all those functions to wheels is impractical.

There must be some irony in judging the practicality of adding functionality to a game object.

If your taking 100-500 more lines of code to add something that's not going work too well, then it's impractical (at least a pain in the ass).
I'll wait till someone makes a servo for gmod (wired or not).

Another option: Phoenix Storm's (ultimate?) Premium model pack has gears and tooth bars, (basically rack-&-pinion stuff) that, with a accurate linear adjustment and/or measurement, would allow one to provide... (I think the term is called 'dead-reckoning'?) to rotational movement forces. Just a thought...

-Kodin-

PS: I know it's not something that is always practical in every design, but it can be useful, for either force-applying, or position measurement, so long as you don't need more than say, 360-degree rotation... (Anything more and the toothed-bar becomes a bit too long to easily and cleanly manage in a build --unless of course, what you are building happens to be a behemoth of a prototype mega-battle-walker-of-dO.Om). --(Granted the forces required would probably cause a rack-and-pinion system to break if used for such a large and/or massive device. (Say, for the hip or knee joint actuators... Simpler to just use hydraulics as they do in the real world for that.)

I did this with Phx's gears and it did work good. I used one wired fixed hydraulic to mount the 'tooth bar' and the biggest gear (I needed precision, not the speed). But hydraulics have only their length as input, so there is a need for some logic behind that would set the length with some precision.
