Ok we are going to continue editing our key frames – I’m going to select my sphere, I'm going to walk up the hierarchy. Now in the previous demonstration, I had selected the translate z, and we saw that there was no change in value over time. So, this curve in the graph editor is simply taking up space. I would like to clean up my graph editor by removing curves that will actually represent any change over time. There are so many curves you'll be generating in the graph editor - it is important to try to keep your work space as clear as you can. To do this, go to edit, delete all by type, static channels. Let's take a look at what's changed. We now no longer have the translate z channel available to us, because there was no change, so it was deleted. Rotate x and y are now gone because we have been only rotating in the z axis. All the scale channels are available because there was change over time, on all three scale channels. I am going to continue editing my animation. I want to see the effect I'm having as I edit and I am going to use the dope sheet help me select keys, so I'm going to work in the 3-panel view. Ok, I am taking a look at my animation and I am seeing that some of the tangents, due to some of the other edits I've made have changed in ways that I would like to change them. I am going to break tangents. I would like this to be a more linear interpolation - looks like my Move tool; middle mouse button click; straighten out the tangent along the path to give me a faster fall into this position. This tangent I'm also going to show it up a little bit, I don't mind that it’s ease is coming out of the bounce a little bit, but not as much as it is currently indicated. Take a look at this one, it's not too bad, but I am still going to change it a little bit - here we go. Let's take a look at how our animation is coming along. It's actually working pretty well. One concern I have is, it doesn't seem to be bouncing as high it ought to for the second bounce. Too much energy is being absorbed. So I am going to edit the value of that bounce. Now I've edited this tangent; if I set a new key frame I'll lose the changes I've made to this tangent and have to reset these values as indicated by the tangents. So I'm going to select the key frame, got the tangents fixed. Now I should be able to move the key frame in the graph editor; now I’m going to move to that point in time so I can see the effect I'm having in the perspective window; I'm going to use the move tool; middle mouse button click. If I press shift, when I press the middle mouse button and move the object or the key frame in the graph editor, I can confine my movement to one access, which in this instance is the Y axis. So you can see I'm moving my ball straight up in the air, to a higher point, its in a second bounce - feels better. OK that's look pretty good. Another nice thing is I can see a direct relationship here in the values as to high he balls going to be as compared to how it was when it started. Let’s take a look at that bounce - that feels better to me. Now I am going to create a simple, playback of that bouncing ball, using a tool called play blast. The play blast I'll find under window, play blast. I can set the time range for my play blast if I wish. I can set it according to this time slider or I can set a start and end. I'm going to set a start and end - we get 45 frames. When I click the play blast button, Maya is capturing, frame capturing images, from the perspective window, and plays it back for me. It plays it back at quarter size; you can see it automatically opened up media player and there's my bounce - very good.
