position timing problems based on the frames per second.

good morning,

i dont know if the title is right but here is my problem:
i have a simple head bobbing script from the unity wiki page but i get into some trouble with the translation speed of the movement. the "bobbing" animation gets different speed based on the frames per second.

is there a way to get a fix speed no matter which frames per second the client has? here is the basic script:

Code (JavaScript):

1. private var timer = 0.0;
2. var bobbingSpeed = 0.18;
3. var bobbingAmount = 0.2;
4. var midpoint = 2.0;
5. public var swayholder: GameObject;
6. function LateUpdate () {
7.     waveslice = 0.0;
8.     horizontal = Input.GetAxis("Horizontal");
9.     vertical = Input.GetAxis("Vertical");
10.     if (Mathf.Abs(horizontal) == 0 && Mathf.Abs(vertical) == 0) {
11.        timer = 0.0;
12.     }
13.     else {
14.        waveslice = Mathf.Sin(timer);
15.        timer = timer + bobbingSpeed;
16.        if (timer > Mathf.PI * 2) {
17.           timer = timer - (Mathf.PI * 2);
18.        }
19.     }
20.     if (waveslice != 0) {
21.        translateChange = waveslice * bobbingAmount;
22.        totalAxes = Mathf.Abs(horizontal) + Mathf.Abs(vertical);
23.        totalAxes = Mathf.Clamp (totalAxes, 0.0, 1.0);
24.        translateChange = totalAxes * translateChange;
25.        transform.localPosition.y = midpoint + translateChange;
26.               transform.localPosition.x = midpoint + translateChange;
27.               transform.localPosition.x = translateChange;
28.              
29.     swayholder.transform.localPosition.y = swayholder.transform.localPosition.y + translateChange / 2;
30.     swayholder.transform.localPosition.x = swayholder.transform.localPosition.x + translateChange / 2 ;
31.  
32.              
33.              
34.     }
35.     else {
36.         transform.localPosition.y = midpoint;
37.         swayholder.transform.localPosition.y = -0.3520508f;
38.         swayholder.transform.localPosition.x = 1.216995f;        
39.  
40.     }
41. }

 

Use FixedUpdate
