Studying Physics in Colin Mc Rae Rally 2.0

Posted on by Viljami

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.

Breaking Down Mortal Kombat II

Posted on by Viljami

I’d like to spend a moment describing my experiences about the second Mortal Kombat game that was released for Sega Mega Drive in 1993. The game has some technical limitations as Mega Drive isn’t, and wasn’t even back in the days, the most powerful platform to release a game like this. Arcade version of this game might have been smoother but we aren’t going to go there today since it’s been too long time for me to talk about that here.

As a software developer graduate I can see some things while playing that I don’t know if they are so clear for people that don’t know computers, technology and programming so well. This small blog post is here for you to dive a bit deeper on how the game is played. I also understand that some people are way better at playing this kinds of games. I have only spent some tens of hours playing Mortal Kombat. Also I like to note that I am concentrating on Mortal Kombat II here instead of all two dimensional fighting games. Yes, there are many of them and I have to mention Street Fighter series here.

This stuff is very interesting for me. I can see how the game kind of “reads” your moves. The opponent, it is this time a computer, reacts to your moves. It can make a move that is most suitable for a certain situation. So the key to winning your opponent is to react with a move that is the best move in your situation. You have to time this move correctly. You have to be in a right position. And this isn’t all there is to it. You can make moves freely. You have to define when and at which position to make the move that is correct move for you to make the opponents health bar decrease.

Fighting games have come a long way since the days of 1993. It is very different to play against the computer than it would be to play against a player. I know that games like Mortal Kombat and Street Fighter are very popular as genres of electronic sports. So you can have a competition against human players. This is how the game was designed. It sometimes feels like the computer is cheating but what else would it do than read your input and position and react as fast and powerfully as possible.

But to talk more about the game. It’s a great game. I find it very fascinating. The graphics are better than the first Mortal Kombats were. It seems like the development team have done a great work. The game has twelve different characters that have their own strengths and weaknesses. This makes the game even more interesting. To beat the game you have to know how to play with not only one character but many different characters that have their unique special moves and so on. You could actually compare and describe which characters are best against a specific opponent.

I am not sure what the basic attributes of all the characters are. I haven’t touched or even seen the source code. I am not aware if this code is available or is it “open source” or closed code. I know that Mega Drive didn’t have so much memory to use. Graphics and movement took a lot of processing from this gaming console also. When considering that this game was released in 1993 it is a game of very good quality. There is also a port for PC. If you are a big fan I can recommend to getting your hands on Mortal Kombat X. And to be honest I have to say that I just some days ago ordered Mortal Kombat 11 for PS4. I had to do it because the price was, I think, this time good. I hope this short blog post can give you inspiration wherever you are and in what situation with work or studying you might be.

Spending some time with Gran Turismo 4

Posted on by Viljami

As I may have mentioned earlier I kind of missed PlayStation 2. So it’s finally time for me to pick up Gran Turismo 4 and start getting in to playing it. The game was released in 2005. With over 700 cars and almost endless possibilities to race and tune your vehicle to it’s maximum performance it brings a huge game for the player to enjoy for a long time.

My history with Gran Turismo begins as I picked up the first game of the series. It was end of the 90s. Graphics were beginning to become more realistic. The capacity of CD-ROM brought more details and content to be used by game developers. Gran Turismo was also good for promoting PlayStation. It soon became clear that PlayStation would see some very nice driving games. The second Gran Turismo game was also released for PS1. The third one started the era of PS2s racing games.

There are lots of games that are dealing with driving a car or some another vehicle.
Gran Turismo made a difference. It delivered almost pure racing. Almost nothing else included. It had real cars and not only some but hundreds of cars that actually existed also in real life. It’s amazing to understand how the attributes of these cars tell you exactly how they behave while being handled on the road. These include mass, suspensions, tire selections, engines capability and so on. There are lots of things to mess with. You can modify the settings while testing the car. Upgrades to your car are essential. You have to win to get money for the upgrades.

I really enjoyed the first Gran Turismo. I hope my experiences with the fourth game of this series are enjoyable. I have to bring this fact up. The graphics aren’t too smooth or nice. It has been 15 years since the release. What could you expect? As the sixth game was released for PS3 there haven’t been a release of this series for a while now. Gran Turismo Sport did appear to the gaming stores but I think it was more of a eSports type of game.

We are expecting Gran Turismo 7 to be released for the newest PlayStation. I have to Google this one. And yes, the release is scheduled to quarter 1 / qurter 2 of 2021. As Gran Turismo 4 is even today a very enjoyable game with many interesting features you have to wonder a while what could there be inside the seventh Gran Turismo game.
