The Open Augmented Reality Teaching Book - Create And Code Augmented Reality!

And so if in the middle of this, I want Z to change. So there's a good trick you can use, and you can use this, um, on pretty much any property that has more than one kind of piece to it, like an X and a Y property, if you want to control them independently. A when you have more than one value in a property, you're, you're actually giving after effects on array, which just means more than one value. Semi-colon done. Okay. So these variables, these are just making it so that the answer that I'm giving after effects is easier to read. Now, what I'd like to do is link the X, Y, and Z pieces of the scale to these three sliders, because these are all separate, so I can control them separately. So let's set the scale back to 100, 100, 100, 100, 100. And what I'm going to do is I'm going to add, I'm going to select this layer, and I'm going to add an expression control. And you can see that now these controls actually control the scale and they're all independent.

I'm going to put some key frames on these expression controls here, and I'm going to set all of these to zero. I could, I could zero out Z here, right? If I let's say I unlinked these and I put a key frame here, and all I want to happen is for this thing to scale from zero on Y over 12 frames, I want it to scale up like this, right. Right. Maybe there, and if I move the camera on, oh, that's too far. So I'm going to add 500 right there, do the same thing. I want to move it down 500 pixels, because I know that the each side of the cube is a thousand pixels tall. Okay. So I, I know if I go to this box comp and I go into one of these sides, I know that this, uh, each little side of the cube is a thousand pixels by a thousand pixels. The first thing you should know about Dreams is it'll have a traditional campaign. But it doesn’t have to be. To get a better result you have to use a picture with single FG object.

I can put another key frame there and I can start to change Z. And you actually let me switch this over to my value graph, by the way, if any of this is unfamiliar, please watch the intro to animation curves, a tutorial that will get you a little bit more familiar with this, this animation curve editor. There's a ton of tutorials out there to help you get started. Okay. So I'm gonna hit a key and, you know, like what I usually like to do, I mean, I could just kind of do the math and I had, but sometimes it's nice to kind of move it or move the anchor point around so I can kind of get a sense of, okay. If, um, you know, if you really are getting into a heavy 3d scene, it might be easier to do it in a 3d app. 1: at the top of the working screen of this software, we have a menu bar which will change with the changing the method of working; these methods are modeling, rigging, animation, dynamics, etc. To stop at a point double click or press enter.

I'm going to hold option and click the stopwatch and add an expression to the scale property. And that way I get a separate X, Y, and Z property with scale. All right. Then whenever you have a property in after effects like scale, right? It's expecting, you know, when, when you create an expression, you have to end the expression by giving after effects the answer. So half of that's 500. So moving it down 500 would be adding someone type in plus 500 right here, and then hit enter, and it'll do the math for me. Um, so if we did five 40 is where it starts right in the middle, and we wanted to move it down 500 pixels. So you guys can see, this is where the floor starts out. Needless to say, you can still apply the concepts to the latter. The gist of the combat system is as follows: players can be punching an enemy in one direction and can still attack others approaching from the sides and behind. Video game fanatics can, in fact, transform their pastime into an occupation where they can earn money. Rotation can also be performed in the Update loop of our game to have the Model rotate throughout the game.
