I'm try to make animated logo, like at example, but add the color of the logo and transform of color clother to a destination object.
This code is work, but logo is going to be only black and white, what is need to be added to code?]]> http://flintparticles.org/forum/comments.php?DiscussionID=377&Focus=1272#Comment_1272 2010-07-27T08:09:09+01:00 2011-12-11T04:05:54+00:00 Richard http://flintparticles.org/forum/account.php?u=1

To modify the color during the tween, add a ColorChange action to the emitter. For example startEmitter.addAction( new ColorChange( 0xFFFF6600, 0xFF0000FF ) );

ColorChange action to the emitter. For example

startEmitter.addAction( new ColorChange( 0xFFFF6600, 0xFF0000FF ) );]]> http://flintparticles.org/forum/comments.php?DiscussionID=377&Focus=1273#Comment_1273 2010-07-27T08:24:40+01:00 2010-07-27T08:25:10+01:00 Turic http://flintparticles.org/forum/account.php?u=392

That will require a custom action. The action would store the original color and target color for each particle in the particle's dictionary and then transform the color using a similar algorithm to ...

action, like at http://flintparticles.org/forum/comments.php?DiscussionID=26&page=1#Item_0 ?

Sort of. You'll probably want a custom Initializer to set the start and end colors for each particle and store these in the particle's dictionary, and then a custom action similar to the ColorChange ...

thank a lot, i'll try it.
