I am trying to move a throttle up and down in the 3d space .I am using a 3d throttle object in side the cockpit to move up and down using mouse point i tried for moving the 2d sprite using above code it works fine but not working for moving a 3d throttle object.

Answer 1

Mathf.Lerp(inputvalue, -10f, 10f);
I think your error is you are trying to interpolate your input to 10, when the Lerp function can only interpolate [0,1], Mathf.Lerp
You need to call it as Mathf.Lerp(-10, 10, inputValue);
Once you get the interpolation value just add that to the translation
var value = Mathf.Lerp(-10, 10, inputValue);
transform.position += Vector3.forward * value;

Answer 2

Find out how far your throttle is:
Vector2 throttleDownPosition = Vector2.zero; // Or whatever it is. I can't tell from your code.
Vector2 throttleUpPosition = new Vector2(0f,1f); // Or whatever it is. I can't tell from your code.
Vector2 throttleCurrentPosition = knob.anchoredPosition;
// Calculate ratio between current throttle / full throttle
float throttlePercentage =
Vector2.Distance(throttleCurrentPosition, throttleDownPosition)
/ Vector2.Distance(throttleUpPosition, throttleDownPosition);
Then, using what position and rotation your 3D throttle object should be when throttle is at 0%:
Vector3 startPosition
Quaternion startRotation
as well as the position and rotation your 3D throttle object should be when throttle is at 100%:
Vector3 endPosition
Quaternion endRotation
you can use Vector3.Lerp and Quaternion.Lerp to find the appropriate position and rotation for the current throttle setting:
Vector3 lerpedPosition = Vector3.Lerp(startPosition, endPosition, throttlePercentage);
Quaternion lerpedRotation = Quaternion.Lerp(startRotation, endRotation, throttlePercentage);
throttleObject.transform.position = lerpedPosition;
throttleObject.transform.rotation = lerpedRotation
