Though I could receive MOUSE_ENTERED or MOUSE_EXITED in MyBehaviour object, the PickCanvas could not pick a shape (it always returns a null PickResult object in this case). My scene graph tree: BG |-> TG -> S |-> TG -> S |-> Behaviour I am very appreciate if you could give me some advices. Thanks in advance.

Also, if you've written a custom picker, I suggest making sure that it can pick something even in the most simple of circumstances (ie. knock up a scene graph with a huge cube bigger than the viewport and set the pick to run with x-y parameters 0 0, etc. Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         AppletTalk.com Forum Index -> 3D Graphics API's for Java All times are GMT Page 1 of 1   Jump to: Select a forum Java Newsgroups----------------Java DiscussionsWeb-based java games comp.lang.java 3D Graphics API's for Java Java: Support and criticism Java System Announcements comp.lang.java.api JavaBeans Java and CORBA Java and Databases comp.lang.java.developer Java GUI Toolkits Java Help comp.lang.java.javascript JVM, native methods and hardware comp.lang.java.misc Java Language Programming Security and Java comp.lang.java.setup Java Software Tools comp.lang.java.tech ibm.software.java.linux  Non-English Java Newsgroups----------------Java Language (German)Language Java (Français)Java (Italian)  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
