How do I read UV values?

[roid100]

Hello,
When I searched the boards, I found this way to calculate the posion of Uvs.

float fX = (sourceTexture.width) * UVs[0].x;
float fY = (sourceTexture.height) * UVs[2].y;
float fX2 = (sourceTexture.width) * UVs[1].x;;
float fY2 = (sourceTexture.height) * UVs[0].y;
float fWidth = fX2 - fX;
float fHeight = -(fY2 - fY);

Almost of all sprite has no problem with this code,
but just some of sprites in the same Collection has got a problem.
They have zero value for 'fWidth'

I attached a JPG.
As you see, some of my sprites has the same value for Uvs[0].x and Uvs[1].x

What is the problem?
How can I read the value of Uvs?

Help me please~~

Refer to tk2dClippedSprite.cs - SetGeometry. The orientation of the sprite is explained in there with ascii art diagrams.
Some sprites may be rotated, which is probably why having a problem with it doing it the way you're doing it there.

Yes!
I've checked it, and it had been rotated.
One more question please.
Is there easy way to check if it is roated or not in script?
If there is, how can I do?

Yup, that code in tk2dClippedSprite there tells you.

// Prior to tk2d 1.92,
if (sourceTexture.flipped)  // its rotated and flipped (what usually happens in tk2d)

// tk2d 1.92++
if (sourceTexture.flipped != tk2dSpriteCollectionData.FlipMode.None) // if !flipped
// tk2d 1.92 onwards supports other forms of flipping / rotating.
