If you're up for a challenge, you can now create your own car!
What do you need? Drawing skills and a good car specs source. I recommend https://www.automobile-catalog.com/#gsc.tab=0
Under downloads you'll find an ods tool where you can fill in the values. You'll notice that they are already filled in. These are the values for the DX40, so you have a reference. In the ods file you'll find 4 tabs: global, engine, drivetrain and tires. The most important ones are the first 3.
For the sprites: I've added some examples below. Make sure that you have at least 2 sprites: one pointing forward and one at an angle. The more, the better of course. As you can see, the Porsche also has sprites pointing slightly downwards.
I also recommend some crash animation sprites, like the spinning animation of the Porsche. Otherwise crashes will look silly, unless I disable them, like I did with the Countach.
You can put all sprites into a single file, but you can also put one sprite in one file. Just make sure that every file has the same size and that every sprite has the same scale. Don't go for less pixels than the Porsche below.
For the color of the car: if you want the possibility to change the color in the game (in the future), the car can have up to 7 shades. (Black, white and other non-panel colors like brake lights, glass, ... are not included.)
All done? Send the files to yves_dorny@telenet.be and if I approve your car, I'll put it in the game!
If something isn't clear, please ask.
