360 degree rotation

[silversteez]

i know this is a probably really easy, but i can't figure it out...

i have a TweenRotation on a sprite that i want to rotate 359.9 degrees clockwise and then loop. is this possible? what To and From values should i use?

currently any To value greater than 180 causes the sprite to rotate less rather than more.

Don't use TweenRotation for this. You need to do your own turning logic: something like Quaternion.Euler(0f, Time.deltaTime * 180f, 0f);

I try to changed ..

1.    cachedTransform.localRotation = Quaternion.Slerp(Quaternion.Euler(from), Quaternion.Euler(to), factor);

To

1.    cachedTransform.localRotation = Quaternion.Euler(Vector3.Slerp(from, to, factor));

It's a bad idea?

[ArenMook]

Yes, it's a bad idea. You're interpolating floats here which will give you a very different result. Interpolating a quaternion rotation from -360 to 1 degree will result in 1 degree of rotation. Interpolating a vector from -360 to 1 will result in 361 degrees of rotation.

Like I said, create your own tween script. Don't modify NGUI's tweening.

okay, i got it.
thx

Hi,

I use NGUI/Examples/Scripts/Other/Spin.cs for this and it works perfectly fine. 

Maybe give it a try, since it's easy as just attaching to what you want to spin and play around with the Rotation speed x,y,z which are the only parameters there are.

Why not add that TweenQuaternion to NGUI by default?
I think it's not the first topic on this subject I see and people may need it

Hi - I'm trying to spin a "radar sweep" which is a simple sprite. No matter what I use - Spin.cs, Quaternion.Euler, Rotate, etc... The sprite hovers right around 3 degrees of rotation. It seems as though something is holding the rotation to 0 and my attempts to rotate get applied once before it goes back to 0.

This sprite is in a UIPanel. Any ideas?

Thanks,
Phil

All I can suggest is find that "something". There is no magic, and NGUI won't rotate anything for you. Whatever it is, you're doing it.

[nah0y]

Just use a script with this in the Update method :
mTransform.RotateAroundLocal(Vector3.forward, mRotationSpeed * Time.deltaTime);

I appreciate your reply!  I found the something. I was controlling it from another component in my last project and I did not take that control out.

I have been a GUI programmer for 30+ years. My company has decided to go 3D for all future business apps. I am finding NGUI to be an indispensable tool - so powerful and flexible.

Thanks again,

Phil
