Status: RESOLVED FIXED

(Developer Documentation Graveyard :: General, defect)

Description

[Darin Adler]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-us) AppleWebKit/418 (KHTML, like Gecko) Safari/417.9.3
Build Identifier: 

The example at <http://developer.mozilla.org/samples/raycaster/RayCaster.html> has a bug in it. In Safari 2.0 it shades the walls as it should, but it does not in Firefox nor in the latest TOT WebKit. The reason is that the drawSliver function does not call beginPath, so it just keeps adding lines to one large path, overwriting itself.

Reported as a bug in WebKit as <http://bugzilla.opendarwin.org/show_bug.cgi?id=9607>.

Reproducible: Always

Actual Results:  
Walls appear to not be shaded.

Expected Results:  
Walls should look shaded as they do in Safari 2.0.

Not sure I got the right component for this.

As far as i can figure out, this is the right component. Confirming that the behavior of RayCaster is wrong here as well.

Ok it's the wrong product, moving it to the right one.

Added beginPath() and closePath() calls to drawSliver().
