    Xpand Rally: danni e ferite

       (0 reviews)

    La Techland ci ha inviato un dettagliato documento che spiega come saranno implementati, nel prossimo Xpand Rally, i danni alla carrozzeria delle vetture ed addirittura le possibili ferite al pilota. Per saperne di più leggete il testo qui sotto:

    Car damage model and driver's injuries simulation. How it works in Xpand
    Rally. Techland - the developer of Xpand Rally - has today revealed the next of
    game's unique features - the complex model of simulation and visualization
    of car damage and parts wear and the way that driver's injuries influence
    car handling in the game.


    The use of Open Dynamics Engine in Xpand Rally to achieve fully dynamic and
    interactive environment of track also resulted in correct and realistic
    simulation of car damage.

    The parameters of all objects in the game are fully configurable so it is
    possible to set their various features individually, like: coefficients of
    friction, elasticity, number of degrees of freedom, maximum velocities and
    many others. That makes all objects surrounding the tracks have individual
    influence on the car during a collision depending on their physical
    parameters. A good example is plastic posts frequently placed on the road
    shoulders that can be easily "mowed down" by the car. Although it depends on
    the velocity of the car the influence on its damage will remain
    insignificant. It will be limited to impactions of bumpers, sometimes the
    bonnet or only to scratches of the paint when we hit the post with the side
    of the car. Road signs are a similar case but adequately to their physical
    properties they will have some more influence on the car. The signs are much
    heavier and harder which makes the forces affecting the car during a
    collision cause more damage. All drivers know about those dependencies on
    the roads and having the choice between "mowing" a plastic post or a road
    sign they will choose the first option taking care of their cars and health.
    We were able to move these intuitional drivers' feelings into the game.

    Because the car in Xpand Rally with its mass and velocity is subject to all
    physical laws known from the real world, analogically to the previous
    example just like in real life it will be much better to hit a road sign
    than a tree. Such examples can be given endlessly with regard to fences, low
    walls and finishing on buildings.

    As it is now clear what mechanism and rules cause car damage
    lets discuss the damages themselves. In Xpand Rally the possible damage
    types are:

    a.. mentioned before scratches of the paint

    b.. damage of the body of the car, such as:

    a.. impactions and partial or full detachments of bumpers

    b.. full and partial detachments of spoilers

    c.. impactions of: wings, doors, bonnets, roof

    d.. full and partial detachments of doors and bonnets

    e.. cracking and full breaking of glasses in all windows

    f.. damage of reflectors and wipers

    c.. damage of suspension and brakes

    a.. ripping tires and their loss

    b.. flapping wheels and their detachment

    c.. damage of springs and dampers

    d.. damage of stabilizers

    e.. damage of brakes of separate wheels

    d.. damage of engine and transmission system

    a.. damage of the cooling and lubrication system resulting in engine
    overheating and seizing

    b.. damage of the turbine influencing the power of the engine

    c.. damage of the engine decreasing its power and finally stopping the

    d.. damage of the clutch and gearbox eliminating gears or impeding their

    In the game all damage is shown either by direct visualization if it's
    possible (e.g. body of the car) or by HUD display and indicators of: engine
    temperature, suspensions and steering system, brakes, transmission and
    engine, turbocharger and electrics.

    Besides of damages that are results of collisions most of parts important to
    car handling undergo the simulation of wearing due to exploitation. Thus
    drivers preferring spectacular drives with long side slides and often
    blocking wheels will have to more often invest in changing tires. The
    wearing of parts has special meaning for both driving the car and the
    economical layer of the game. It's forth to add that the system of parts
    wearing simulation features elements of risk management. Players that drive
    cleanly and effectively, not damaging the cars much and so being able to
    repair them inexpensively will more likely successfully finish a race.
    However each who risks driving a strongly impaired car can expect
    malfunctions being results of wearing various parts that will either make
    the driving much harder or even make it impossible to finish a race.

    Driver's injuries system is a completely new element in rally games. The HUD
    in the game displays the driver's physical condition. During subsequent
    collisions not only the car is damaged but also driver's injuries are
    simulated and symbolically visualized as the change of color of various
    parts of the indicator. The health condition of the driver has direct impact
    on his reactions to sudden situations on the road and to how efficiently he
    handles the car. Head injuries can cause blurred vision that will surely
    affect driver's judgments and his reaction time. Limbs injuries can cause
    altered reactions to the attempts of turning, accelerating or braking. It is
    analogical to a true life situation where a driver complaining about his
    shoulder aching would manipulate the driving wheel in limited range or
    slower. The intention of the developers of the game the driver's injuries
    simulation system is about to increase the effect of realism of Xpand Rally.
