I'm trying to make simple game where you can drive car. Unfortunately I get runtime error 216. Most likely my fault, because I'm net to this soft, so I attaching my project.

Hi and welcome to these forums!
You get a "null pointer referenced in expression" error in the log window too. The problem is in Car.OnUpdate.Condition.Expression:
"return CurrentModel.CollidedWith.ClassId == Ground.ClassId;"
CurrentModel.CollidedWith is only valid to use in OnCollision. So move this Condition to Car.OnCollision instead.

Thanks! However now I have another problem. Wheels of my car don't want to rotate. I'm using following script in Keypress binded to W key. I'm attaching project file. KeyPress is in OnUpdate.
Also sorry for noob questions, but I'm new to it aaand, you know.

For some reason I can't remember the keys need to be specified in caps. So just change to W instead and it will work.

Hej Ville,

Because Windows returns the QWERTY key events in the 0x41 - 0x5A range, which corresponds to the capital letters in the ANSI map. The lower case ordinals actually map to the numpad and function-keys among others
