Nov 9, 2008 - posted in Software: I have a mac computer and im using fire fox. I tried downloading shockwave 10,11, flashplayer and the message still comes up. I know that Xtra Havok Physics scene is used for 3d gaming but i can't. When I try to download runescape gold generator it says the application failed to initialize properly 0xc0000135 What do i do? Itunes is an apple/mac application. Make sure you downloaded the Microsoft version. What does this mean This application requires an Xtra Havok Physics Scene that either does not exist or failed to initialize. May 16, 2009 Where can i find a havok physics download? I saw some havok physics demos on youtube. And i was just wondering if theres a download where you can build that type of things and that crash it down or do whatever you want with it. Where can I download the XTRA Havok Physics Scene for MAC? Ask where can I download Havok xtra for Mac.
Wreaking Havok with Physics, Part 1 August 16, 2001 by A question on one of the Flash lists the other day got the little grey cells to thinking about a project. I didn't have any particular use for this project, nor was I likely to in the future, but still it seemed a fun thing to investigate.
The question concerned creating a molecule viewer in Flash that would let you view the atoms and links in 3D. An organization named the Research Collaboratory for Structural Bioinformatics (RCSB) has developed something called the (PDB) which is, in their words: 'the single worldwide repository for the processing and distribution of 3-D biological macromolecular structure data.' The PDB contains many thousands of molecule descriptions in a text file format also known as PDB.
This is a portion of a PDB file. ATOM 14 H 1 2.491 0.574 0.546 ATOM 15 H 1 -2.299 1.616 1.538 ATOM 16 H 1 -2.069 -1.381 -1.314 TER CONECT 1 2 6 12 0 CONECT 2 1 3 15 0 CONECT 3 2 4 11 0. This portion of the file bridges the section describing the 3D coordinates for the last three of the 16 atoms in the molecule (all hydrogen molecules) and the connections to the first three atoms (atom 1 is connected to atoms 2, 6, and 12). There are already good viewers available for PDB files. If you've taken a chemistry course within the past few years, you're probably already familiar with (a PDB viewer Netscape plugin) and (an open-source standalone application for Unix, Windows, and MacOS).
The original question had cited a British Director developer's that displayed PDBs. So as I learned about the PDB format, I didn't particularly feel the need to build my own viewer.
What I wanted to do was have some fun. Playing With Your Molecules Mothers always tell you not to play with your food. They never warn you about splitting atoms, though.
I always regretted never getting certified at college to run the little they had on campus. I'd have to satisfy my atomic urges in some other way. As I was looking at the structures of various proteins with RasMol, I thought: 'I wonder how they'd bounce?' That's right, bounce.
Wouldn't it be cool if you could drop the molecule on the floor, fling it against a wall or twirl it around? What if you could add a little physics into the mix? So I set out to show how, if you were so inclined, you could make a 3D molecule viewer that lets you get your hands on those dirty little atoms. To see the final piece. To get to this movie, I started off by looking at the demo in the section of the site.
Building the Box First off, insert an empty Shockwave 3D cast member into a movie and place it on the Stage. Then create a loop script so that the sprite can play uninterrupted. The movie's Create Scene behavior sets up the scene. This behavior will be applied to the 3D world sprite. If we want to be able to fling the molecule around with impunity, we need more than a floor. We want a box with sides and a top: on beginSprite me s = sprite ( me.spriteNum ).member s.
ResetWorld - create ground mr = s. NewModelResource ( 'GroundPlaneRes', #box) mr. Width = 250 mr.
Length = 15 mr. Height = 500 m = s. NewModel ( 'GroundPlane', mr) m. Position = vector ( 0, 250, - 150) - create roof m = s.
NewModel ( 'roof', mr) m. Position = vector ( 0, 250, 150) - create walls m = s. NewModel ( 'wall1', mr) m. Position = vector ( 0, 0, 0) m.
Scale = vector ( 1, 0. 03, 20) m = s. NewModel ( 'wall2', mr) m. Position = vector ( 125, 250, 0) m. Scale = vector ( 0. 03, 1, 20) m.
Rotation = vector ( 0, 0, 180) m = s. NewModel ( 'wall3', mr) m. Position = vector (- 125, 250, 0) m. Scale = vector ( 0. 03, 1, 20) m. Rotation = vector ( 0, 0, 180) This code creates a five-sided box that's missing one of its sides. Each side of the box is a separate model, made from the same modelResource, the box named GroundPlaneRes.
The box is scaled and positioned so that the camera can look in from the open side. The top will keep the molecule from being thrown up and out over the box's edge. Adding a camera and a light will finish the overall environment: - point camera c = s. Camera 1 c.
Position = vector ( 0, 600, 0) c. Model ( 'GroundPlane'). Position + vector ( 0, - 100, 50), vector ( 0, 0, 1)) c. Hither = 1 c.
Yon = 1000 - add a light s. NewLight ( 'light1', #point) end The camera is aimed at a position above the GroundPlane model with the pointAt command, which we'll look at some more later.
This command uses two vector values in a list,with the first defining the point the front of the model aims at, and the second defining the side of the object (a camera, in this case) that is the top. At this point, we've got a well-lit box and nothing more.
You can't see the top of the box, but you can look around with the Shockwave3D window's camera controls if you don't believe me. You've Got Balls Our next step is to add the spheres that will represent our atoms. Just like with the walls, we can use a single modelResource as the basis for the three spheres. We can add this to our Create Scene behavior: - create balls mr = s. NewModelResource( 'Ball1Res', #sphere) mr. Radius = 10 m = s. NewModel( 'Ball1', mr) m.
Position = vector ( 0, 150, - 50) m. Rotation = vector ( 90, 0, 0) m = s.
NewModel( 'Ball2', mr) m. Position = vector ( 0, 150, - 90) m = s. NewModel( 'Ball3', mr) m. Position = vector ( 0, 150, - 130) The three balls are positioned along a vertical axis, 40 world units apart from each other. Creating Havok So far, this scene is static. Our next steps are going to change all of that. The Havok Xtra is a limited version of a physics engine that's been used in games and 3D applications.
It's right there on your Director 8.5 CD-ROM, along with two cast libraries of behaviors to go with it. The first step to adding physics to our world is to define a Havok type cast member. This is done from the Insert Media Element menu or by typing new (#havok) in the Message window.
Name the new Havok cast member BlankHavok. To initialize the Havok engine, we need to add one of the behaviors from the Havok Setup library.
Drag the Physics (No HKE) behavior onto the 3D world sprite and accept the defaults in the Parameters dialog. They should look something like this. In Havok parlance, an HKE is a Havok Export file, created by 3D programs like 3DS Max that support Havok in the modeling application.
Since we're going to create everything through Lingo, use the No HKE version of the Physics behavior. This step associates the Havok physics cast member with the Shockwave 3D world and needs to happen before any other scripts talk to the physics engine. Use the Behavior Inspector to move the Physics behavior before Create World. Hardbody Now that we've got physics, we need to tell the objects in our scene how to react, by giving then physical attributes. Add the line in bold at the beginning of the Create World behavior: on beginSprite me s = sprite ( me. SpriteNum)Member hk = member ( 'BlankHavok') s. ResetWorld Then, add two lines to each of the definitions of the balls.
Use the same code in bold for each ball. NewModel( 'Ball1', mr) m. Position = vector( 0, 150, - 50) m. Rotation = ( 90, 0, 0) m. AddModifier ( #meshdeform) hk.
MakeMovableRigidBody (m. Name, 10.0) Adding the #meshdeform modifier to the ball makes it work with the Havok physics engine. The makeMovableRigidBody command creates an object in the physics world that can interact with other objects. Havok supports both moveable and static rigid bodies.
Static bodies don't need to check for collisions with each other, cutting down on the amount of processing needed to run the engine. If you run the movie at this point, the balls will just fall through the floor. To Havok, the floors simply don't exist yet. Gravity exists - that's what's pulling the balls down - but the walls haven't been given any physical properties yet.

To do that, we'll use the makeFixedRigidBody command. Again, the #meshdeform modifier is added to the model, then it's added to the physics engine. This is how the definition of the ground plane should change. create ground mr = s. NewModelResource( 'GroundPlaneRes', #box) mr. Width = 250 mr.

Length = 15 mr. Height = 500 m = s. NewModel( 'GroundPlane', mr) m. Position = vector( 0, 250,- 150) m. AddModifier ( #meshdeform) rb = hk.
MakeFixedRigidBody (m. Friction = 0. Restitution = 0 The friction and restitution properties of the model control how other objects slide and bounce off of the surface. Instead of passing through the floor now, the balls fall slowly onto one another, then the stack tips over and they roll their separate ways (because of a certain amount of randomness built into physics engines, it won't be exactly the same every time). Add the same four lines after each of the wall and roof definitions, and the balls won't roll off the edges.
You can download a or version of the Director 8.5 source file so far. In our next installment, we'll add some color, link the balls together, make them respond to the mouse, and draw the connecting links.
