Hosting problems

Thursday, December 11th, 2008 | announcements | Comments

It looks like I’m having some troubles with my hosting for images, source, and example .swfs.

Please be patient while I try to resolve this.

Thanks,

John

*update – Looks like everything is good again. Back to cranking out examples.

Swapping a Plane with a MovieClip

Thursday, December 11th, 2008 | examples, tutorials | Comments

The idea here is to setup your material as normal and bring the plane front and center. When the plane reaches front and center, you put your regular 2d object on top and start it playing (or start interaction, etc.). Then when it’s time to go back into plane form, use plane.material.bitmap.draw(embeddedVideo) to update your material to the latest snapshot of where the video left off.

Don’t get too hung up on the tweening code. It’s not important to the concept.

The .swf is about 2 megs, so be patient while it loads.
