TIFFANY HOLMES>SOUND AND LINGO>SPRING04>HANDOUT 3

EVENTS>Examples of event handlers>You want to play a sound when the user clicks a button:

on mouseup

puppetsound “laser”

end

SOUND PROPERTIES>Examples>volume, loop, pan

NOTE: Sound channels are not sprite channels. There are a total of 8 sound channels in Director—only two are visible to the eye.

Examples: Setting sound properties using dot syntax

sound(2).volume = 130 --255 is loudest, 0 is silent

sound(6).loop=true --true means play the sound as a loop

sound(3).pan=100 --play sound only out of right speaker, 0 is even balance, and –100 is left speaker only

COMMANDS: puppetsound (best for internal sounds), playfile (best for linked sound files)

Examples: This statement plays the file named Thunder in channel 1:

sound playFile 1, "Thunder.wav" OR Puppetsound 1, “Thunder.wav”

This statement stops the sound playing in channel 1:

sound(1).stop() OR puppetSound 1, 0

Example: This Lingo fades in sound channel 3 over a period of 3 seconds from the beginning of cast member introMusic2:

sound(3).play(member("introMusic2"))

sound(3).fadeIn(3000)

Example: The following statement changes the volume of sound channel 4 to 150 over a period of 2 seconds. It can be a fade up or a fade down, depending on the original volume of sound channel 4 when the fade begins.

sound(4).fadeTo(150, 2000)

Example: This Lingo pans the sound in sound channel 2 from the left channel to the right channel:

repeat with x = -100 to 100

sound(2).pan = x

end repeat

CONDITIONALS>Basic structure

if –something is true—then DO SOMETHING—execute lingo command

Example: This statement checks whether a sound is playing in sound channel 1 and loops in the frame if it is. This allows the sound to finish before the playhead goes to another frame.

if soundBusy(1) then go to the frame

FUNCTIONS: A word or phrase that returns a specific number. I.E: random(), soundbusy.

SoundBusy is a function that returns true or false, is a sound playing in a specific channel or not? See example of its use under conditional statements.
