Update Log…

• Car is turning a lot, so we may reduce turn values.
  Change “maximumTurn” and “minimumTurn” values >>> 15 to 10, 10 to 4
  After that we must care on speed for turning values.

  Car.js

  Line 26:
  var maximumTurn : int = 10;
var minimumTurn : int = 4;

  Line 583:
  Divide “topSpeed” with 6.4 to decrease turn range.
  if(speed > topSpeed / 6.4)

  Line 586:
  Divide “topSpeed” with 5 to decrease turn range on high speed.
  var speedIndex : float = 1 - (speed / (topSpeed / 5));

• Smoke is so dark and small. We may do some changes to make it like steam. SkidSmokeEllipsoid Particle Emitter
  Min Size: 1
  Max Size: 5
  Min Energy: 3
  Max Energy: 6
  Min Emission: 100
  Max Emission: 150

  Color Animation[2] : RGBA 151,151,151,88
  Color Animation[3] : RGBA 218,218,218,33

  Size Grow: 2
  Force X-Y-Z: 0.1

  Particle Renderer
  Length Scale: 2
  Max Particle Size: 0.25

• For a better vision, change “Main_Camera”‘s height to “2″ in “Car Camera” object.
• A race is need bigger tires. Scale (X) all wheel sizes to 1.4, change all wheel position (X) to 0.05
• Wheels’ steering graphic for left & right is not enough for a car, so we may update it.
  
  Car.js
  (Line 397) Multiply maximumTurn with 2.2 => ea.y = steer * maximumTurn * 2.2;

  It will not change the maximum turn value of the car but graphics.

• There is a lot smoke on tires so we may reduce for lower speeds.Car.jsLine: 338
  Decrease 23 instead of 15.
  var skidGroundSpeed = Mathf.Abs(w.groundSpeed.x) - 23;
