Hello world! I'm talking about a program that has Loki waving. I would like to point out a few details about this, because in the next video, were going to make a procedure with Loki waving. So it's important to understand what we have here to start with. I've written code for Loki. I would like to have other bipeds wave. And, a human is a little more difficult to do because we have an idea about what people look like when they're waving. It's a little easier to make a cat wave because It'll look okay we don't really care that it doesn't look exactly like a cat because we don't see cats waving that often. First of all, I have used variables where ever possible That makes it a little easier to adjust it. For instance, you can see the amount to turn the shoulder is used in a few places and if we had that one place it's easier to work with. the same with the amount to turn the elbow, the amount to turn the wrist and the speed that we want to wave at. I've also added comments, makes it a little easier to understand the code that were using. Use doTogether: We want to raise the arm into the waving position. We are turning the shoulder, the elbow, and the wrist. You might play around with that. Practice waving, do it in front of the mirror, and see what joints you're using when you do some action that you would like to animate. Next, I'm going to wave by moving the elbow back and forth. This is a vigorous wave. You could also do that by using the wrist. We have three times we turned the elbow backward and then forward using the variable amountTurnWrist and I used an animation style begin and end abruptly and the amount the duration is the speed to wave. If you go back there you can see speedToWave is .25 and then we put the arm back down. and I really just copied this to the clipboard and pasted it and where it said left I changed it to right. and it's a good idea to end an animation back where you started so that the next action may depend on him being in that starting position and that's it for now, be sure to watch the next video.
