(javascript) I am trying to have my headbob values increase when left shift (sprint) is pressed, so it makes u feel like you are sprinting. Here is what i have:

```
private var timer = 0.0;
var bobbingSpeed = 0.18;
var bobbingAmount = 0.2;
var midpoint = 2.0;
function Update () {
waveslice = 0.0;
horizontal = Input.GetAxis("Horizontal");
vertical = Input.GetAxis("Vertical");
if (Mathf.Abs(horizontal) == 0 && Mathf.Abs(vertical) == 0) {
timer = 0.0;
}
else {
waveslice = Mathf.Sin(timer);
timer = timer + bobbingSpeed;
if (timer > Mathf.PI * 2) {
timer = timer - (Mathf.PI * 2);
}
}
if (waveslice != 0) {
translateChange = waveslice * bobbingAmount;
totalAxes = Mathf.Abs(horizontal) + Mathf.Abs(vertical);
totalAxes = Mathf.Clamp (totalAxes, 0.0, 1.0);
translateChange = totalAxes * translateChange;
transform.localPosition.y = midpoint + translateChange;
}
else {
transform.localPosition.y = midpoint;
if(Input.GetKey("left shift")){
var bobbingSpeed = 0.25;
var bobbingAmount = 0.7;
var midpoint = 4.0;
}
}
```
