Wierd bug in engine? Happens only when Build&Run Fullscreen

Unity Engine
1

I have HeadBobbing script in my Maincamera, and it works normaly. But if i Build Run game At Fullscreen (not tested windowed) bobbing goes wrong speed. Copy that code, paste it to the javascript and attach that to the main camera on First Person Controller prefab. Any help is welcome.

private var timer = 0.0;
var bobbingSpeed = 0.18;
var bobbingAmount = 0.2;
var midpoint = 2.0;
function Update () {
if(Input.GetKeyDown(KeyCode.LeftShift)){bobbingSpeed = 0.02;}
if(Input.GetKeyUp(KeyCode.LeftShift)){bobbingSpeed = 0.01;}
	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;
	}
}

your code is missing the * Time.deltaTime in the line where it applies the translation change.
without this the code is FPS dependent and as the standalone runs at different speeds it will also result in a different bobbing behaviour

there are a few threads on this, just search for FPS independent coding

So translateChange = waveslice * bobbingAmount * Time.deltaTime; should be correct?

Solved here solution

private var timer = 0.0;
var bobbingSpeed = 0.18;
var bobbingAmount = 0.2;
var midpoint = 2.0;
function Update () {
if(Input.GetKeyDown(KeyCode.LeftShift)){bobbingSpeed = 10;}
if(Input.GetKeyUp(KeyCode.LeftShift)){bobbingSpeed = 6;}
	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 += bobbingSpeed * Time.deltaTime;
		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;
	}
}
