I have been browsing through your banner inspirations:
http://greensock.com/forums/topic/12477-inspiring-html5-banner-examples-with-gsap/?hl=html5%20banner and found this really nice particle animation created by user Oliver15Years:
I am refactoring it to create a steam animation but can't figure out how to kill the particle engine ("spawnSteam") in my timeline.
I would like to ensure that the generator is being killed in my playEnd function. I tried adding spawnSteam.kill(); // but it didn't work..
Thanks so much everyone!
