Quaternion values between inspector and script

Hi I cant figure out why I am getting different quaternion values between altering objects via inspector and through script.

I am trying to rotate an object and have constraints set that when the quaternion X and W values meet a threshold to spin negating the oscillation of quaternion values. My current script works when I rotate an object through the inspector. I cant find a way to rotate an object in game however through quaternion it appears the rotate command is the only solution and when uses that my script does not register my constraints.

Any thoughts would be really appreciated.

 

Can you show a code example of how you're trying to rotate an object in script?

 

Sure - Have this object as a child to circle swap gameObject. I have circle swap at rotation (0,0,0)

Code (CSharp):

1.  
2.         if (transform.localRotation.x < 0 && transform.localRotation.w < 0)
3.         {
4.  
5.             if (!alter)
6.             {
7.                 transform.localRotation = new Quaternion(0, transform.localRotation.y, transform.localRotation.z, 1);
8.                 circleSwap.transform.localRotation = new Quaternion(180, circleSwap.transform.localRotation.y, circleSwap.transform.localRotation.z, circleSwap.transform.localRotation.w);
9.                 alter = true;
10.             }
11.         }
12.  
13.         if (transform.localRotation.x > 0 && transform.localRotation.w > 0)
14.         {
15.  
16.             if (alter)
17.             {
18.                 transform.localRotation = new Quaternion(0, transform.localRotation.y, transform.localRotation.z, 1);
19.                 circleSwap.transform.localRotation = new Quaternion(0, circleSwap.transform.localRotation.y, circleSwap.transform.localRotation.z, circleSwap.transform.localRotation.w);
20.                 alter = false;
21.             }
22.         }
23.  
24.  
25.         // Left Rotation
26.  
27.         if (transform.localRotation.x > 0 && transform.localRotation.w < 0)
28.         {
29.  
30.             if (!alter2)
31.             {
32.                 transform.localRotation = new Quaternion(0, transform.localRotation.y, transform.localRotation.z, 1);
33.                 circleSwap.transform.localRotation = new Quaternion(180, circleSwap.transform.localRotation.y, circleSwap.transform.localRotation.z, circleSwap.transform.localRotation.w);
34.                 alter2 = true;
35.             }
36.         }
37.  
38.         if (transform.localRotation.x < 0 && transform.localRotation.w > 0)
39.         {
40.  
41.             if (alter2)
42.             {
43.                 transform.localRotation = new Quaternion(0, transform.localRotation.y, transform.localRotation.z, 1);
44.                 circleSwap.transform.localRotation = new Quaternion(0, circleSwap.transform.localRotation.y, circleSwap.transform.localRotation.z, circleSwap.transform.localRotation.w);
45.                 alter2 = false;
46.             }
47.         }
48.  
49.  
50.         print(transform.localRotation.x + " " + transform.localRotation.w);

 

So this works with Rotating the object through the inspector

 

When I add say -
transform.Rotate(100 * Time.deltaTime, 0, 0);

Everything in that code is negated and the values oscillate

if I try -
Quaternion pos = transform.localRotation;
pos.x += 1 * Time.deltaTime;
transform.localRotation = pos;

the values stop at 1 and the ability for the math to add linearly dies past 180 degrees. It appears that Unity is capping this quaternion value behind the scenes.

 

Looks like you're making the mistake everyone makes on their 1st try: mixing raw quaternion values and degrees (there are dozens of old Qs like this, with various explanations.)

 

Yep, if you want to convert degrees into a quaternion, use Quaternion.Euler.

 

Thanks for the responses!! I believe I have solved the problem. I learned my lesson to not use the inspector for rotation and do everything through script. I had to rewrite my code a bit, but coincidentally it was simpler.
