In this movie we are going to animate clouds using Behaviors on our Groups as opposed to Layers. If it's not already open we're in the O2_LayerVsGroup project. Now open your Project pane F5 and let's checkout how this is built. We are going to animate Clouds_4, so go ahead and open that up, and you'll notice we have a bunch of layers that make up all these tiny puff balls. Now, we could apply behavior to each little puff ball, but that would be a little tedious. Let's just apply the Throw Behavior to the Cloud group. Go ahead and select Could_4, go up to your Menu bar, click Add Behavior, Basic Motion and Throw.
Click to drag and choose your direction, kind of want it to fly off towards the right and let's hit the spacebar and see how that's going. Now I created each one of these individual layers because I'd like them to move slightly independently to give the affect of a cloud. Simulations to the Rescue. Let's go to the Library, Behaviors and Simulations. The one we want to use is Random Motions. This just applies a little bit of Random Motion to anything we applied the behavior too. So drag- and-drop that right to Cloud_4.
Select Cloud_4 and hit your spacebar to checkout what's happening. And not much. The key to random motion, we are applying it to a group is to check the Affects Subobjects box. So go ahead and give that a check and now let's hit the spacebar and see what happens. Why don't we rewind to the beginning, hit the spacebar and see what happens. That's looking pretty good. There you have it. A little glimpse of how powerful behaviors can be when they are applied to Groups instead of Layers.
Now feel free to go ahead and animate the rest of the clouds to further reinforce what you just learned about Behaviors.
