Appearing In A Videogame

Ever since seeing Dr. Doak in Goldeneye on the N64, I've always wanted to feature as a character in a videogame. In F1 2020, I have finally realized that dream. Photos of my head were taken from multiple angles, and then my head was scanned with a 3d scanner. A skilled 3d artist then reduced the poly count, tidied up the geometry, and created materials from the photos. Below are some renders of the 3d model of my head that is used sporadically as a background character in cut-scenes and animations throughout the game.

Camera Study

Today I've been looking at implementing some more advanced camera work from other games. In the video below of Mario Galaxy 2, while Mario fights the blue Magikoopa the camera remains focused on the Yoshi egg in the middle of the play-field while maintaining a fixed distance from Mario himself:

Below I have implemented a similar system in Unity, where the camera focuses on the central cylinder while maintaining a distance from my character. I have also added the ability for the camera to track the characters' vertical movement to maintain what I call a "Cylinder camera" which would be useful in a third-person game when climbing tower like structures:

Framing

Following on from the GDC talk 50 Game Camera Mistakes. I have been working on the camera system for my Unity game. This weekend I worked on automatic framing of the character. A safe frame is defined by a proportion of the screen within which the player can move freely without the camera having to move to track the players' position. Once the player leaves the safe frame, the camera moves to frame the player back in the center of the safe frame. Two different safe-frames are used for an in-air and grounded character so jumping from the ground does not cause the camera to follow the player immediately.

With the camera not always "fixed" onto the player's location, there is more of a sense of independent movement from the player in the game world.

Balancing

I have been working on game feel recently, trying to make my character feel responsive with "tight" controls. I have studied a number of influential games including Super Mario 64, Super Mario 3d World, Rayman 3d and Mario Galaxy. I took screen-measurements and analyzed video captures to discover the "secrets" to making a jump feel good to play and I think I've nailed it.

The factors I have considered are reality based projectile motion and conservation of previous momentum. But also game-physics things such as in-air control, re-targeting orientation in the the air and after-touch. I now have a script which allows me to set up a jump for any required height and distance (so levels can be set around the maximum values), but is also responsive to control and doesn't feel like traveling along a fixed parabola.

Dare To Be Digital

This Summer, myself and a team of two other programmers and two artists are pinning our hopes on making it into the Dare To Be Digital computer games development competition held here at the University of Abertay Dundee.

The aim of the competition is for a small group of non-professional game developers to get together and create a game of their choice within a 10 week period. Game choices can be very diverse but must adhere to a strict set of rules and guidelines imposed by the competetion. Previous years standards have been very high and this year the competition is bigger than ever with at least 275 teams having already entered (we were team 275). I think we have a good team and a good concept but at the moment its just a matter of waiting to hear the results of our application.

.X-Files on PS2

After an unsuccessful attempt at geometry instancing on the VectorUnit hardware of the PS2, I have opted for plan B. plan B being to write an X-File (DirectX model) loader for the PS2. The irony of loading a Microsoft proprietary format model on Sony hardware is not lost on me.

The X format is something I have wrestled with before but never at such a low level. I have always relied on the D3DX helper functions such as D3DXLoadMeshHeirachyFromX(). Working on the PS2 does not allow for such liberties, so I'm writing my parser from scratch in standard C++.

Overhaul Movie 1

I've just uploaded a video of Overhaul in action after a weeks work. You can see the video below:

As you can see I now have a physics based car (using PhysX) driving around with suspension, breaking, steering and motor torque all working correctly. All input is mapped to an Xbox360 controller using analogue inputs to allow precision handling such as pressure sensitive steering, acceleration, braking and camera movement. I have also written some shaders to allow the headlights and brake lights to be turned on (by the user and when breaking), and a day-night cycle for the skybox.

What you cant see in the video is that I have actually written a car class so I can have as many cars as the computer allows without becoming too slow and I have done the majority of the sound work for the car including a user activated horn, acceleration sound and brake screech.

The game is coming along nicely, especially as it's not due until May. The next step is to start on programming the opponent AI and track system.

XInput & XACT

Having used XNA for a while now, I have noticed that two of my favorite features are the ability to use the Xbox 360 controller and the XACT Audio creation pipeline so I set about writing classes to allow these in my current projects.

COLLADA

I've been looking for a 3D file format for quite a while which encapsulates more advanced features than the trusty old .x format. As I'm now integrating physics into my engine, I need a format that will allow me to export physics parameters directly from a content creation tool. It would also be nice to be able to set up cameras and splines within the modeler. COLLADA offers all of these features along with support from the major content creation tool vendors such as Autodesk (3DS Max & Maya), NVIDIA (FX COMPOSOR 2+) and many others.

I’ve just finished reading COLLADA Sailing the Gulf of 3D Digital Content Creation (ISBN: 1-56881-287-6) which is a great book and explains the format and content creation pipelines in somewhat excruciating detail – which I see as a positive thing.

Another thing I’ve been looking at recently is OpenGL, I’m normally a DirectX person as I find D3DX and in particular HLSL to be a more complete solution than the current state of OpenGL (GLUT & GLSL). I’m also not a big fan of the numerous OPENGL versions and extensions floating about they just add to the complexity. However I’m going to look at using COLLADA with OPENGL and DirectX and maybe even a bit of XNA time allowing. This is going to be a personal project for now, so I will only be able to do it when I’m not too busy with work for my MSc which may be pretty rare in the forthcoming months.

Cheap Shadows

Today I learned how to render Planer Stencil Shadows. Looking at the example code we were given, I came up with a way to implement similar shadows with barely any cost within my previous PhysX boxes Demo. Here is a short video:

The way I ended up implementing the shadows didn't actually use the stencil buffer at all, in fact it simply took the scene that was already in my subset managers list and rendered it again applying a shader to all subsets. The vertex shader offsets the world space vertices of each subset by a pre-defined shadow matrix - calculated by a projection from a light ray onto the plane defined by (0,1,0,0). The pixel shader simply returns black with a 60% alpha.

This ended up being a very cheap implementation as the geometry had already been gathered in the subset manager and I had already written a method to render the whole scene with a global shader applied to all subsets.

I hope to be able to expand my understanding of shadows and take on shadow mapping in the near future, but that's it for now.

PhysX Character Controller

Work continues on the PhysX side of things. I have now updated all of my PhysX demos to use Cyclones MeshObject class instead of a DirectX standard primitives. Here is a short video (the reflective cylinder is the character):

I have also worked on a nice rag doll demo and a collision callback demo. The collision callback demo plays a bumping sound when two meshes collide with each other. In the rag doll demo, I am rendering some primitives in the location of the PhysX Actors which are bound together by joints i.e. cylinders for arms and legs, a sphere for a head etc.. I want to change this so that I tie the bones of a skinned mesh to each physics actor. This wouldn't be difficult if it wasn't for the lack of available skinned meshes around, or the complexities involved in making them export properly from 3ds Max (problems with normalized skin weights specifically). I will probably resort to using the good old Tiny.x from the DirectX SDK. More Soon.

Update Complete

Recently, Ive been working on updating the DirectX SDK used for Cyclone. I stuck with the DirectX 9.0 release for well over a year, but decided it was time to upgrade.

The biggest problem in updating was the way the latest DirectX SDK (August 2007) has changed the interface classes for mesh data. After a couple of days I worked out how to update my mesh, frame and animation parsers along with a few minor changes to the sprite class.

More PhysX Boxes

I've just written some gameplay into the PhysX Boxes Demo posted earlier. There are now 4 'player' boxes on the ground (there can be as many as I like as its just an array but 4 is nice). Each player box can now emit a magnetic force on the wire framed boxes scattered about the arena. I'm thinking about making a small multiplayer game based on this. Here is how it looks so far:

As you can probably see, the shaded boxes that start off on the ground are the 4 players. In the video I switch between controlling each player and attract up the wire frame rigid body boxes.

In this video, the PhysX API is used to create a simulation containing 80 boxes. Each box is positioned in the sky above a ground plane. When the simulation begins, the boxes fall to the ground and bounce off each other. The video also shows that the user can apply forces to each box which, in this case send them back up into the air.

A hemisphere light is made up of two colors, sky and ground, that are interpolated between based on the normal; that is, areas with normals pointing towards the sky are "sky"-colored, and areas pointed towards the "ground" are more "ground"-colored.

The hemisphere light is implemented by linearly interpolating between the sky color and the ground color based on the angle between the normal and sky direction. The angle is calculated by doing a dot product between the normal and sky direction. This results in a -1 to 1 value that, when remapped to 0 to 1, is perfect for linearly interpolating between the two colors. The Vertex shader also morphs the skulls vertices, giving a rippling effect.

New Blog

I have now added a new blog feature to my website. I wrote this web-app from scratch in PHP with a MYSQL database in the background. It allows me to update this page from anywhere!

This blog should be updated regularly with information about what im doing.
