CCG/PFX: Sound Scripts

Sound Scripts

Soundscripts give ambient or directional sounds to objects. They cannot be used on track, bridge or spline objects. Refer to the new tracksound container options to change track sound on a bridge or tunnel for example.

Wav files should be located within the same directory as the config.txt file. Examples as follows:

MOJUNCTION

Breakdown of Soundscripts

repeat-delay

1 or 2 numbers (min, max, in sec) time to delay between the end of the sound playing, and playing it again randomised between (min .. max)

default min = 0 default max = min

attachment

Attachment point on the object to which the sound is attached.

Default: The sound will attach to the origin of parent object (not used for ambient sound)

distance

2 numbers (metres)

1st number = the distance at which the sound is played at 100%

2nd number = The cut-off distance. Doesn't affect the volume of the sound default: 50m, 150m

sound

List of .wav files to play (randomly picked if more than one)

volume

Gain of the sound Default 1.0 = 100%

ambient

0 or 1, default 0 is off Ambient sounds have no 3D "position" and may be stereo. Non-ambient (positional) sounds are positioned on the object and must be mono - see attachment above

value-range

2 numbers, currently used only for day/night sound effects.

Midnight is 0.5, midday = 0.0 or 1.0 Where the numbers are not the same, this sets the start and end times for the sound to play.

Default 0,0 (off)

trigger

A trigger may be used in an event file (.evt) associated with an animation. It plays at selected key frames of the animation as defined in the event file. Sound files may be triggered in this manner, and from scripting.

Used in the mojunction example (switch lever) the "toggle" action is automatically triggered when the lever is operated and the sound plays. The sound doesn't play until the trigger message happens, as a result of the lever operating.

nostartdelay

0 or 1, default 0 If not set, the sound will have a short delay before playing, this stops flanging (flanging is a really nasty sound caused when several copies of the same sound are played at once).

dayloop, daysingle, morning, night are sub-container names chosen by user. Each is a single word only. Do not use a space.

Please refer to examples and detailed explanations of additional tags in the earlier chapters of this document.
