4. Mathematical equations.

3. General plan.
• The car simulator, will be programmed in JavaScript.
• It will have a windscreen view, side window views, and rear window view.
• It will have mirror views:
oSide mirror views.
oWindscreen mirror view.
• It will have indicator light switches.
• It will have a gearstick, steering wheel, and foot pedals.
• It can be turn-based, like an Interactive Fiction game. Or, it can be played at
different speeds. It could respond to a script, which programs the drive.
• The purpose of this simulator, is to teach people how to drive. (You can make
one, too.)

4. Features of the first version of the simulator.
• There is going to be, a road with a left turn.
• There is going to be a turn-based simulation.
• There will be a bird's eye view, of the road
with the left turn.
• There will be a clutch pedal, gearstick and
steering wheel.
• The car is going to go along in units, along the
road, and it is going to be steered.
• The simulator will crash, if you get an
instruction wrong.

5. Possible JavaScript functions (or web
programming functions) required.
• Use Scalable Vector Graphics, with JavaScript, for
the bird's eye view.
o Draw a rectangle, with <rect>.
o Use the rotate() and translate()
transformations, with <rect>.
o Use document.getElementById() , to
access SVG tags.
o Use .setAttribute() method, to change the
SVG tags.
• With a turn-based simulation, there is no need
to smoothly animate, the path of the car.
• Use a HTML form, for the car controls.
o The clutch pedal is a toggle button.
o The gearstick is a form control, which has a
dropdown menu.
o The steering wheel has a 12:1 steering ratio.
(Wikipedia says, this is a common ratio.)
• The car wheel turn, is inputted, and the
steering wheel angle, is calculated.
• Dashboard.
o The speed of the car, is displayed. (This affects
the translations.)

6. Equations, for the first version of the car
simulator.
• Speed = distance/time.
• Steering wheel angle = 12*car
wheel angle.
