Studying Physics in Colin Mc Rae Rally 2.0

Colin Mc Rae Rally 2.0 is a very interesting game in many ways. I wrote recently about different strategies you can have in this game. Now I would like to return to the physics and how this part of the game is handled. I think this game was the first rally game and also among some first racing games that I really liked (Gran Turismo was also great) and got into. It was released for PC and PS1. I played both of them.

There is no doubt that the way CMR 2.0 handles the part of physical modeling was in its time revolutionary. I know lots about games but I also have studied a bit of physics. I have learned physics mainly through school and by studying it in a school of applied sciences. However I am not a physicist. I am more of a software designer. So I know about some coding stuff also. This might open this fact a bit of how I find thinking about these subjects extremely interesting.

I haven’t seen any source code from this game. This is a commercial game and its code isn’t open source. I think for many of the fans of this game this doesn’t come as a surprise. The game was hugely popular. Releasing it as a freeware would be, well, stupid, you might say. However there are some very interesting details that open up for me as I play this rally game.

Let’s think about friction. It deals with surfaces. In a car you can have different tires that behave differently on different surfaces of road. So this is one thing. While driving on icy or snowy road you might want to use chains with tires. While driving on tarmac you want to use soft tires. And on wet surface you use special tires that perform nice on for example wet tarmac. Same goes for muddy surfaces or roads that are of gravel. You have to have a good grip on the road you are driving and friction can give you this.

There is a force that is effective on any road that you can drive on the whole planet Earth. It is called gravity. You have to have good and sufficient suspension in your car. On roads that are bumpy you have to have more suspension for overcoming the differences of altitude. Too much suspension is not good either if you drive on flat road.

You can also break and accelerate. You turn the wheel in right direction at a right time. The key is to try to steer correctly or at least keep the car moving as fast as possible. If you don’t break at a correct time you get to grass or some other surface that slows you down. Crashing also slows you down. This has everything to do with a thing called momentum. If an object doesn’t receive any push to any direction it keeps moving with the speed it has to the direction it is moving. At different time there is different amount of push to the vehicle. If nothing gets pushed the car keeps moving. Bigger objects take more power to get moving and are slower to stop moving. So the more mass you have the slower you are.

I think this is enough physics. I repeat what I said earlier. This is not so precise of a study. I haven’t seen any source code and I didn’t describe my theory so thoroughly. I hope this motivates you to learn more about physics. You can find more information using your favorite search engine. I definitely feel that you will get more excited about this particular rally game.

First games I remember playing

I remember how I got started with gaming. It was 1980s. Playing video games was already popular. There had already been some consoles like Atari 2600 and Commodore 64. PC was also popular. First gaming system that I got to play must have been PC. And it was somebody elses. Our family got our first computer and I think it was 1987 if I remember correctly. So I was three or four years old and I had already begun drawing with pencils. I could recognise some letters but I was too young to start writing or reading. I got to learn those skills later in school.

Games that we had on this PC were interesting to me. We had some Sierras classics like Police Quest, Space Quest, Leisure Suit Larry and Kings Quest. I was fiddling around with some QBasic games. I even wrote a small game with QBasic later as I was a bit older. I didn’t clearly understand the full potential this machine had. So I didn’t get into coding so much. I was also drawing something with early Paint this PC had.

I learned to write my first words playing Larry. I didn’t understand this games sexism. My parents allowed me to play it. Sexy parts of the game weren’t so clear and we understood them later when we grew more. It is a soft game on this matter. At least I think so. I once asked my father what was a “prophylactic” and he answered to me “Gee. I really don’t know. Can you figure it out from the picture? It looks like a gem or something.” So I was allowed to play this Larry and it was only seventh game in this series that got my parents a little bit worried because I was young. I played seventh Larry maybe in 1996 or something like that.

There were so many interesting games. Some of them were Sopwith, Space Commanders (Space Invanders Clone), Bubble Bobble, Test Drive and so on. Too many to list here. I don’t remember so much of the techical side of our computer. Our dad upgraded its processor to 286 so before that the processor was much slower than that. One day we tried to play Wolfenstein 3D on the computer but we failed to run the game. We also installed newer diskette drive. So it had drives for 8-inch and 3½-inch diskettes. It’s funny to think how bad the first mouse was so we got a new mouse also. The standars then was the classic mouse with a ball in it. Monitor of this device was heavy and our computer was able to run EGA graphics. There weren’t any VGA or Super VGA available.

I would have liked to add a picture about this machine but I could only find this picture of floppy disk and its disk drive. I took this picture some years ago as my parents were getting this old computers all parts to recycling center. I’m not so into retro computers. This old computer we had was replaced by Mega Drive and later by PlayStation as number one gaming console. This PC was not functioning so nicely. It used to get stuck and I would have to press “reset”. Back then all computers had this function. The personal comnputer we had served properly and because of that I can still remembert it and it really launched my gaming activitites and layed the foundation for it.

My gaming consoles

PlayStation Classic

I bought my PS Classic for 40 €. The price was so low that I figured I should buy it. This device flopped very sadly. It had only 20 games. Gamepad included has too short cable and it doesn’t have analog sticks. Games included were not so special though it had FFVII and Metal Gear Solid. If you consider buying this think seriously about modding it and don’t pay too much. The price was originally 120 euros.

Retro Trio HD+

This is cool gaming console. It combines NES, SNES and Mega Drive. What that means is that you can play all cartridges that you buy from gaming stores or you might have kept them for a long time. Retro Trios price was 110 € so I think it’s cheap. It also gives HDMI output so the graphics aren’t too messy. If you want play with older retro type television I don’t recommend this. In this case you should get original systems.

PS3

I didn’t really buy this one. It was a gift to my then-girl-friend-now-my-wife. It was expensive as new but now you can pick one, I think, for under 100 euros depending on games or controllers that are included. It has a hard drive. Depended on model the size of hard drive varies. There was also some kind of backward compatibility with PS2 and PS1 games which depends a lot about the spesific model of PS3. So yep, there were multiple models, for example Slim Model and so on.

PSOne

My first true console that brought us the experience of 3D graphics. I bought this one from flea market for as low as 15 euros. It didn’t have controller with it so that effects to the price of course. PS2 controllers are compatible with it so I just played with my PS2 gamepads. It requires memory card so I had to buy one for about 10 euros. Memory cards work with PS2 but PS2 memory cards don’t work with PS1. This is a smaller version of PS1. Very cool product I would say and definitely retro.

Xbox 360

I bought this one from a friend who sold it to me as she didn’t play so much and also her gaming console was becoming old. She hasn’t bought a new console. Not yet at least. I have maybe 30 games for this and I have mainly picked them up from flea markets and gaming shops. I invested 70 euros in this one. I first thought I would play and get all Xbox 360 only games so first games I played and also completed were Alan Wake and Halo 3. I also have Gears Of War, Mass Effect, Fable, Halo, Halo wars and so on. This system has backwards compatibility on some original Xbox games but not all. The list can be found Googling.

PS4

I bought my PS4 as my birthday present in 2014. That was also a moment I turned 30 years old. It cost me about 500 euros and I had Tomb Raider with it. So the game and console summed to this amount of euros. I didn’t really like this one so much. It had no backwards compatibiltity, I didn’t like so many of games that were released to it. It was a bit of a disapponitment. It had some good games. Games I played most were NBA2K14, Dirt Rally and Diablo 3. When companies like Sony keep coming up with new devices every six years or so I am currently thinking not buying fifth PlayStation but don’t you just follow me. Make that decision yourself.

PC

Personal computer was my first gaming device. It will always be there. I might play old retro games or the most new one. Provides large collection of controllers so you can pick your favourite USB gamepad. Easiest one to modify also if you want to upgrade your hardware or software. Much love to PC.

broken

– original Xbox

Yeah, so I broke my Xbox. I’m not going to buy a new used one to replace it. I now just have a large collection of games that aren’t supported on Xbox 360. So they lay now inside my dungeon and in my closet buried there. I’m not planing to sell them. Maybe some day we see Xbox Classic?

– PS2

This is sad one. It started to malfuction so I opened it up carefully. I tried to clean it. Finally I decided to try to fix it by replacing its optical drive. That didn’t go well as I had a wrong replacement part. So I just screwed back some screws and now it’s in condition that it starts up but you cannot boot a disc. So it’s useless. Maybe I buy a new used one or wait for PS2 Classsics release if there is one coming to us ever.
