BUG about "clipRaycasts" in the UICamera.

[zhing]

I have try to use UICamera.clipRaycasts with a button in the clip UIPanel. But "clipRaycasts" isn't work.

After debug into the UICamera. I found that line 454.

1. if (Physics.Raycast(ray, out hit, dist, mask)) return true;
2.  

at the end of the function "static public bool Raycast (Vector3 inPos, ref RaycastHit hit)" is unnecessary.

Because it override the result by "clipRaycasts" checked.

Try adding "return false;" at the end of the "if (cam.clipRaycasts)" section like so:

1. ...
2. else if (hits.Length == 1 && IsVisible(ref hits[0]))
3. {
4.         hit = hits[0];
5.         return true;
6. }
7. return false;

I have changed the code to:

1. 430:            if (cam.clipRaycasts)
2. 431:            {
3. 432:                    RaycastHit[] hits = Physics.RaycastAll(ray, dist, mask);
4. 433:
5. 434:                    if (hits.Length > 1)
6. 435:                    {
7. 436:                            System.Array.Sort(hits, delegate(RaycastHit r1, RaycastHit r2) { return r1.distance.CompareTo(r2.distance); });
8. 437:
9. 438:                            for (int b = 0, bmax = hits.Length; b < bmax; ++b)
10. 439:                            {
11. 440:                                    if (IsVisible(ref hits[b]))
12. 441:                                    {
13. 442:                                            hit = hits[b];
14. 443:                                            return true;
15. 444:                                    }
16. 445:                            }
17. 446:                    }
18. 447:                    else if (hits.Length == 1 && IsVisible(ref hits[0]))
19. 448:                    {
20. 449:                            hit = hits[0];
21. 450:                            return true;
22. 451:                    }
23. 452:                    return false;
24. 453:            }
25. 454:            else if (Physics.Raycast(ray, out hit, dist, mask)) return true;
26.  

I think maybe it was the right way.
