Exponential Motor Acceleration

I chuckled with your ending bit there. What I'm trying to get at is if you fully throttle the joysticks forward instead of a sudden increase from 0 to 1 in a fraction of a second have it gradually increase over the course of 2 seconds or something of that nature. Ether I believe has answered my question however I haven't tried it yet so I will report back later if it's right.

What I posted is a joystick mapping; it won't do what you just described above.

What you want is some sort of rate limiter.

What you want is called "rate limiting". Searching with that keyword phrase will give you lots of useful information. Here is one document that ought to help.

Okay got it figured out now. Thanks a bunch for the input.
