Unity Realistic accelerometer controls

[anon90445360]

Vector3 acc = Vector3.Zero;
void update(){
acc = Vector3.Lerp(acc, Input.acceleration, Time.deltaTime);
transform.position = new Vector3(transform.position.x, (acc * -aVerticalRotation).x, transform.position.z);
}

I have the above code to move my GameObject vertically (along the y-axis). This works fine except that I want the object to move relative to my motion i.e.

If I tilt the phone some X amount very fast it will move distance Z whereas if I tilt the phone with amount X but slower the distance will be A where Z > A.

I’ve tried to get the current reading subtracting it from the previous reading and multiplying it with the rest but apart from causing a jittery effect it didn’t work exactly as I wanted it to.

Can some one help me achieve this ? I’m quite new to Unity.

Thanks

from what i understand you basically want it so if you move really fast you impart some additional momentum to the object so it moves further.

your got a jittery affect because you multiplied by too high a number (basically you moved the mouse so great a distance in so short a time it skipped whole sections of the screen before being rendered again)

you could prevent this by doing addition instead such as

if current - previous <= 1
add 0
if current - previous <= 5
add 1
if…
all the way up to whatever is a max which doesnt cause jittering
like
else
add 10

alternatly if you used an algorithm you could simply make sure the number returned by that wasn’t too high if it was set a limit and redefine it to the max limit so for example
if your old algorithm was

new_x = (current - previous) * old_x
now you would add

if new_x > MAX_FOR_SMOOTH_TRANSITION
new_x = MAX_FOR_SMOOTH_TRANSITION

finally if you really want to get complicated

read this paper on how microsoft made an algorithm for the mouse acceleration in windows.
(which is basically what your doing)
