addWheel
addWheel(wheel,
wheelPos, axlePos, wheelAxis,
suspensionHeight,
wheelRadius, steering)
Adds a wheel to the vehicle.
wheel:
Type:
KX_GameObject
(The game model of the tire.)
wheelPos:
Tire position from
vehicle object center.
Type: float list [ x, y, z]
Uses local x, y, z float values.
suspensionAngle:
Cosine of the angle
(uses vehicle object center axis)
Type: float list [x, y, z]
Range -1.0 to 1.0
wheelAxis:
Axis of the tire
used to attach it to the axle.
Type: float list [ xAxis, yAxis, zAxis]
Range -1.0 to 1.0
suspensionHeight:
Height of the
suspension. Local value.
Type: float.
wheelRadius:
Radius of the tire.
Type: float
steering:
Type: Bool
True or 1 = tire
used for steering.
False or 0 = tire not used for steering.
