With 's release on the horizon, Rockstar North's technical directors Adam Fowler and Sandy Roger quizzed themselves to provide some insight on the physics and tech -- a FAQ on the subject, if you will -- behind the anticipated game. We also have brand new to tide you over until next week, and don't forget to check back tomorrow for more information from Rockstar North.

Grand Theft Auto IV is the first time North has used the RAGE engine, can you tell us a little about RAGE?

Adam Fowler: The RAGE engine consists of a collection of core game technologies. Its basis is the AGE engine that was developed for previous Rockstar San Diego titles. It contains a rendering framework, a physics engine, audio engine, network libraries, animation engine, scripting language plus loads more. It is mainly developed at Rockstar San Diego apart from the audio engine and a lot of the network code which were developed here at North.

What benefits does its use confer on the development of an open-world game?

AF: The main benefits are from the system level code. As we are continually loading and deleting objects as you drive through the world. The memory manager needs to be robust and deal with continual allocation and freeing of objects without fragmenting memory too much. We have worked very closely with RAGE to get this right. Outside that the flexibility of each system has allowed us to push and pull them in all sorts of directions.

Are there any advantages to the fact that Rockstar have developed and own the engine?

AF: The main advantage is we have control over the direction the engine takes. If we need something for our game we have a direct connection with the guys who would be developing it. We get early access to systems which might not be completely finished but are ready for development use. Bugs get fixed in days, not weeks or months. This has been especially important as we reached the end of the project. We talk to the RAGE guys every day. We know what is happening with RAGE on a day to day basis.

Sandy Roger: Definitely, working with guys in house gave us much more input into the development of the RAGE engine, and gave us direct access to the guys who made it which has helped enormously.

The game feels very different to previous GTAs, both in terms of on-foot handling and vehicle handling - the experience feels somehow heavier. How have you achieved this?

SR: We've tried to make everything feel more realistic, from the weight of the cars and the traction curve of the tyres, to the way that the player leans when running to get round corners.

How do you make sure the game comes together as a whole with the physics reflecting the new tone of the game?

SR: It's quite an iterative process. We try to come up with toys for the level guys to use in their missions, and the level guys come up with mission ideas that require physics, and then we meet somewhere in the middle.

There are a number of different weather conditions in the game, including heavy storms. What sort of effect does the changing weather have on the physics in the game?

SR: The main effect of the weather is in modifying the traction curve for the tires on the road, the result of which is different depending on what surface each wheel is driving on.



The water in GTA IV looks amazing, but how do you cope with reflecting the changeable nature of the sea in the handling of the boats?

SR: The boat handling is developed from multiple water buoyancy samples, each of which are designed to simulate all the distinct effects of bodies moving through the water that we need for realistic boats, like drag and lift that give the boat directional stability and make it aquaplane (lift out of the water at speed). All these parameters are then tuned to make each boat handle as you would expect, which also produces interesting handling characteristics in different sea conditions.

The explosions feel so realistic in GTA IV, how hard is it to create them? How do you map the trajectory of burning debris?

SR: We spent a lot of time tuning the way the forces are applied from the explosions to make the ragdolls fly through the air, props break apart, etc just right. A big part of it also comes from the particle effects. Our effects guy did a brilliant job with the explosions!

When every bullet leaves a mark in the environment, how do you cope with the sheer number of bullets that must fly around the environment in some of the larger gunf!ghts?

SR: The biggest cost of each bullet fired is actually the line of sight test that we have to do to see what it hit, so the RAGE guys spent a lot of time optimising that code to make it as efficient as possible.

There is incredible detail in the physics, I even noticed that shooting a barrel can cause a jet of liquid to spurt out and gradually decrease in range as the pressure reduces or that knocking into a pedestrian can cause them to drop their shopping so that cans roll down the sidewalk. Do these fine detail physics get the same level of attention as the key gameplay mechanics such as driving and running?

SR: Well key things that we need to get right for the game to be fun, like the car handling, get the most attention of course! But aside from those special systems, most of the other cool details come from just getting the basic systems working well. So we spent a lot of time making sure that the building blocks were there for the props guys and the effects guys to make lots of interesting and cool objects to put in the world.
