Quaternion *= operator not working

What could be wrong here ? rotation should not stay zero right ?

Code (CSharp):

1.        
2. Debug.Log(previewFurniture.Template.rotation); // output (0.00000, 0.00000, 0.00000, 0.00000)
3. previewFurniture.Template.rotation *= Quaternion.AngleAxis(90, Vector3.up);
4. Debug.Log(previewFurniture.Template.rotation); // output (0.00000, 0.00000, 0.00000, 0.00000)
5.  

 

You Multiply with zero - the result stays zero.

The first quaternion is invalid. Quaternion.identity is the zero rotation, which is

(0.00000, 0.00000, 0.00000, 1.00000)

.
Fix the rotation of your

previewFurniture.Template

and it will work as expected.

One more thing: you probably want a rotation around the world axis and not the local axis. Quaternion multiplication relies on the order. Left = World, Right = Local.
So you probably want:

Code (CSharp):

1. previewFurniture.Template.rotation = Quaternion.AngleAxis(90, Vector3.up) * previewFurniture.Template.rotation;

 

oh I missed that. I thought quaternion was initialised to quaternion identity. thanks

 

Thanks for the tip, but I think it is not revelant in this situation because

Code (CSharp):

1. previewFurniture.Template.rotation

is not a transform rotation, it's just a value stored in template, and template is not a monobehavior class.
