Algodoo

The text in the display changes when I click on keyboard keys, but the car does not move.

Hm...
I. Did you follow this instruictions?:
1) Press and hold [Enter] for a one-two seconds
2) Press [num 1] key
3) Press [UP] key

II. Did the arrows move when you press [Enter]?

Sorry for my bad English

The numpad should just not be used in algodoo. many people use a laptop with no numpad, or have tenkeyless keyboards like myself. this scene is basically unplayable for me.

Lifestyle94 - What are you talking about? There are no instructions that say to "Press and hold [Enter] for a one-two seconds". All it says is "Click on one of the red buttons"

Xray, the keyboard on the top - help box

Sorry, but I still don't know what you are talking about. What keyboard on top? I see only one keyboard in the scene, It's white with some red buttons, and there is no "help box". There is only a help key, but it is not active. If I'm having so much trouble finding your instructions, then other people probably have trouble too! I searched all over your scene and I could not find your instructions.

In my opinion, its obvious

Make string engine, it will be better. Car is very slow acceleration

I hate all of the spring engines
