What i'm doing and how it started

I build deformable/breakable/crashable cars in something called Algodoo, Algodoo is a 2D physics simulator, after you have built something you can simulate it. The simulator has many tools that you can use to build anything you want. It's not made to build cars in but as i said you can build anything. Other than cars people have made working realistic engines and guns, structures, bicycles with people on them, different games, machines, bombs and more. All my cars together has over 700 000 downloads, the most popular one has over 110 000 downloads. It takes a long time to make them, about a week, because i have been improving them in over 3 years. The latest one (a Buick) has a realistic structure with upper and lower front crash members, ragdoll, airbag, realistic size and performance, good deformation and more.

 You can also download things that other people has made at the Algobox, that's what makes it go from educational simulator to a game. Algobox is where i upload my cars and have my accounts. There are hundreds  of active people uploading stuff to the Algobox every day. A file in this game is called a scene. Good scenes like mine don't  get uploaded much anymore.
My names on the Algobox are MrLucasManSwe and Lucas.







I first got the simulator in 2009 or 2010. I had seen videos of car crashes in the program and got very interested. (I draw cars from the side and i also like to watch car crashes.) I went really addicted to it and found out a new way to build a crashable car, and my brother also played it and made a strut suspension that i have used in the cars ever since.

In the modern one the block inside can't fall out.

Now let's have a look at the new crashable car structure i did 5 years ago.

 First i made a polygon

 Then i prepare the suspension

 Then i cut it up

 I add parts with hinges to hold cut-up structure togheter

 I add strut suspension

 Then the hinges can be modified to break when they fell a pressure, they have a break-limit

 If the strength of the hinge is too low, the car will collapse

This is not real footage, i made it in a minute or two while writing this.

And it's finished. It was really the best i could do when i started. I was 11 years old and was inspired by the cars i was drawing on paper, simple boxy hatchbacks. Yes i was inspired by Volvo when i draw.

I didn't give up on it, i kept liking to build cars and taking it to the next level for each one i made. By now, 2015 i have really pushed the simulator to the limit. I have so many tactics and steps building a car that i can't even remember all of them, it just pops up as i build the car. 

A very important tool is called ''Group''. It adds specific parts into a group, so you only edit one part of the car when the other parts don't need it. It's important for example when making a structure that the doors can't be heavier than the chassis, that's when i need the tool.

Another tool is the abilities of hinges. Hundreds of polygons is what builds up the car and hundreds of hinges hold them together. 

Dodge Ram SRT-10, i made the colors random and hinges visible in the frame and cab, so you can see how it's put together 

This is the structural integrity that makes Algodoo the only program in the world that i can make a realistic deformable car from the side in. Well i don't know any better program, and this one is so easy to use. I'm surprised what i can make in it, it looks like a genius has made the things i have, but i'm not. 

I watched someone making a video on my cars and he said this:
