Re: [JAVA3D] currentKnotIndex

David,   If you type:   PositionPathInterpolator x = new PositionPathInterpolator(...); int y = x.currentKnotIndex   Then you are not within the PositionPathInterpolator. You can only access protected members from within the class (i.e. you have a "this"). To modify or read the currentKnotIndex member you would have to derive a class form PositionPathInterpolator.   Sincerely,   Daniel Selman   [EMAIL PROTECTED] Tornado Labs Ltd. http://www.tornadolabs.com   -----Original Message----- From: Discussion list for Java 3D API [mailto:[EMAIL PROTECTED]]On Behalf Of David Huang Sent: Thursday, June 08, 2000 1:21 AM To: [EMAIL PROTECTED] Subject: currentKnotIndex Forgive me if this is a double post, but I don't think my original post got through. Hi, Can someone explain why I can not access currentKnotIndex from an instance of a PositionPathInterpolator class. From what I understand from reading the API document, PositionPathInterpolator inherited from PathInterpolator, which have a protected field currentKnotIndex. Thus PositionPathInterpolator should have access to currentKnotIndex, correct? So, why can I not do this: PositionPathInterpolator x = new PositionPathInterpolator(...); ... int y = x.currentKnotIndex The compiler gives this error message: 421: currentKnotIndex has protected access in javax.media.j3d.PathInterpolator Please someone clearify, I posted this in the java.programmer newsgroup and no one seems to know. Thanks
