In this chapter, we are going to review few more body types and behavior such as collision events and grouping inside the Newton plug-in. These options are very helpful when you want more control over the simulation that you are creating. For example, if you need the simulation to start or end in different timing according to what you have already set in After Effects, this will be a great helper. If you also need to decide which elements are going to be affected by the collision event, it will give you more control over the desired result.
I'm going to demonstrate these techniques using the Dormant and Collision project, in which we will recreate one of the movie's most important moments. When everything falls apart from the screen, and we are left only with the main title. I want to share with you the final composition that we are going to create. Let's go to full screen, and I'll create a Quick Run preview. >> More and more people define themselves as lonely, and thus, loneliness has become the most common ailment of the modern world.
So in this movie, I'll give you a short overview of the elements that I've already set up, and then we'll start to manipulate them using Newton in the next movie. I'm going to close this composition. And open up the beginning state, Dormant and Collision. Here I already have couple of elements. First of course, we have the narration. I'm going to turn off the audio for now so it won't be in my way.
We also have these precomp, the name is the Innovation of Loneliness. You can double click on it to check what's inside, but basically this is the reveal of the title over here. Now I already masked out the dot above the I letter, because we are going to recreate it over here. The next item over here is the I, and the I is just a place holder where the letter I should be.
The reason that we are seeing it as a blue box is because we need enough room so the little circle that is going to jump on top of the I will not fall from these edges. Then we have this Collision Element. This Collision Element is only visible at the first 17 frames of this composition. And what it is, is a group of two shapes. One is a huge ellipse and on top of it there is a small rectangle.
And we needed to keep this Collision Element as a unit, as one group so Newton should not isolate it or divide it to groups. Just remember it, also note that it has couple of key frames already in place for the Y position inside this timing. So it basically going to move up, and then disappear. The next element here are a group of circles. And we will ask Newton to divide them to individual circles when we are going to start the animation.
So, my aim here is to take this Collision Element, use the existing animation that it already has in order to collide with those little circles and push them up into the air. And then when everything is going to fall apart, we need to define that only this circle will go ahead and stick in place. But before it will rest in place, we want it to bounce on top of this blue square.
So this is the prep work. We can now disable the solo switches so everything will be visible. And I'm also going to turn off the I for this composition and note that these layers are not going to be present at the final state. So I'm building it inside After Effects in order to drive the other layers that I wanted to affect. So at the end stage, we're going to turn off the I for the Collision Element, as well as for the little square represented by the letter I in the timeline.
For now let's make sure that everything is turned on, and in the next movie, we are going to create the simulation based upon these shapes.
