The sounds options are located at the bottom-left of the object properties
box. Sounds are divided into two types : Continuous (Cont.) and Impact.
For both options you may use the default sound associated with most
every object by leaving the sound options un-selected (NULL). You
may also choose from a wide variety of "stock" sounds by clicking the #
button beside the sound box. Once a sound has been selected, it's
name will appear in the box in place of NULL. Lastly, you can get
really fancy and record your own *.wav sounds to use in the game.
To do this, click the "...." button and browse to your file in the same
way you would use windows explorer. Again, the name of your sound
file will appear in place of NULL.
Continuous sounds, like the name implies, are sounds that do not stop.
You would apply a continuous sound to a railway sign, for example, so that
as a truck approaches you will hear the "ding.ding.ding.ding" of the train
bell at the crossing. Another example might be to apply a roaring
crowd sound to the mtm grandstand model, so that as the truck approaches
you will hear the enthusiastic audience cheering you onward.
Impact sounds are the sounds you hear when a truck collides with the
model. Rather than the default thud/crunch sound that you usually
hear when your truck hits something, using impact sounds add a bit of flavor
to your track. To illustrate the point, I will use a fun example
that a friend likes to include in his tracks. When a truck hits the
barn from FarmRoad29, you can hear the old farmer calling out, "Hey you
kids, get off of my lawn!" Adding sounds to your track can enhance
the driving experience.
