Camera Bobbing and Stairs
Hi, Im creating a simple enviroment for a college project. I have added this script http://www.unifycommunity.com/wiki/index.php?title=Headbobber to my character so its head will bob. After doing this I can no longer walk downstairs. What can I do to fix this?
Your problem is in this little bit:
transform.localPosition.y = midpoint + translateChange;
}
else {
transform.localPosition.y = midpoint;Every single frame you are setting your y value to 2. This means that your transform will NEVER be able to fall, jump, or climb anything. You will always be at exactly y = 2.
Try this (edited from your script - mostly unchanged):
private var timer = 0.0; //used as the input to the sine function private var translateChange = 0; //How far the camera is away from it's resting point private var lastTranslateChange = 0; //used to keep track of the delta (change in) translation
var bobbingSpeed = 0.18; //How quickly the camera bobs up and down var bobbingAmount = 0.2; //How high/low the camera's max/min bob is. var settlingRate = 1; //determines how fast we return to 0 position while standing still
function Update () { var waveslice = 0.0; //determine how fast the player wants to move var horizontal = Input.GetAxis("Horizontal"); var vertical = Input.GetAxis("Vertical");
//first, grab a sine value to work with
//not moving --> return to midpoint
if (Mathf.Abs(horizontal) == 0 && Mathf.Abs(vertical) == 0) {
timer = 0.0;
}
else {
//we are moving, grab a bob value from the sine curve
waveslice = Mathf.Sin(timer);
timer = timer + bobbingSpeed; //move along the sine curve for the next cycle
if (timer > Mathf.PI * 2) {
timer = timer - (Mathf.PI * 2); // sine repeats after 2PI. Keep timer in a reasonable range
}
}
//now calculate how much we want to move the camera
//we ARE moving
if(waveslice != 0)
{ //bob up and down based on a sine wave and movement amount
translateChange = waveslice * bobbingAmount; //scale translation by bobbing amount
totalAxes = Mathf.Abs(horizontal) + Mathf.Abs(vertical);
totalAxes = Mathf.Clamp (totalAxes, 0.0, 1.0);
translateChange = totalAxes * translateChange; //scale translation by movement amount
}
else
{ //we are sitting still, smoothly return to 0 position
translateChange = Mathf.Lerp(lastTranslateChange, 0, Time.deltaTime * settlingRate);
}
//now actually move the camera
//move the transform's y component by the delta translation
transform.localPosition.y += translateChange - lastTranslateChange;
lastTranslateChange = translateChange; //keep track of last cycle's translation
}
Edit: changed/added comments as requested
I only wish I could take credit for it haha! It was made by someone over on the wiki, however what you have added makes it work like a charm! Thanks alot for your help!
Looking at this bit of code has been very helpful. One issue I saw was that the private variable translateChange = 0;
then when you get to
translateChange = totalAxes * translateChange;
and translateChange always becomes 0. So I would guess that translateChange should be a non 0 float. I don't know if this change would cause some type of crawl though.
I have a slight problem with this script. The head bobs only if bobbingAmount is more than 2 which results in very much bobbing, to say the least. Anyone else had this problem?
This is great! thank you very much!! Would you be kind enough to just add comments to each line so it's easier to understand exactly what's going on?
Thanks a lot!
There. I tried to add comments to explain what is going on, but I fear that you won't be able to understand it without a Trigonometry class.
Each individual step isn't complex, the hard part is understanding the sine curve { $$anonymous$$athf.Sin() } inside and out.
Thank you very much!!! It's very much appreciated :)))

i've noticed that all the camera men wear a jacket that says BOB on the back..what does it mean? does it represent something?
