Get texture's pixel coordinates when touching a UITexture?
« on: June 21, 2013, 12:14:16 AM »
Have a need to get a texture's pixel coords from touching a UITexture.

Have tried a variety of approaches to no result.

Anyone know how to do this reliably?

Adding, have also tried using RaycastHit.textureCoords but that requires a mesh collider (no other collider is supported) and considering UITexture doesn't expose it's mesh, it's not working.

How else to do this?

Math. You know a 3D click point on the collider. Use the widget's transform.InverseTransformPoint to make it local. Divide by width/height. May or may not have to flip the Y (1 - y).

Ahh right, infer from the collision point; for some reason thought texture coords couldn't be derived that way.

Thanks Michael!
