SetVolume

History: Available since v3.7
MovieVolume & GlobalVolume added to v3.8

Allows the user to set volume levels of: music, sound fx, speech, movies & global(master)

Additional Info
These are the numbers used inside of the setVolume(brackets) to set specific volume types! eMusicVolume (0), eSoundVolume (1), eSpeechVolume (2), eMovieVolume (3) or eGlobalVolume (4)

Syntax:

setVolume(type, volume)

Example 1: basic set volume

-- set music volume to 50%!
setVolume(0, 50)

-- set sound fx volume to 50%!
setVolume(1, 50)

-- set speech volume to 50%!
setVolume(2, 50)

-- set movie volume to 50%!
setVolume(3, 50)

-- set global (master) volume to 50%!
setVolume(4, 50)

Example 2: set all levels based on global (master) volume!

-- let's set the global (master) volume to 80%
setVolume(4, 80)

-- let's create a variable containing difference between global volume current & max volume!
local dif = 100 - getVolume(4)

-- let's store the current volumes for the various volume types into variables!
local musicVol = getVolume(0)
local sfxVol = getVolume(1)
local speechVol = getVolume(2)
local movieVol = getVolume(3)

-- let's remove the difference from the various volume types!
setVolume(0, musicVol - dif)
setVolume(1, sfxVol - dif)
setVolume(2, speechVol - dif)
setVolume(3, movieVol - dif)

-- let's check none of the various volume types are under 0%!
if getVolume(0) < 0 then setVolume(0, 0) end
if getVolume(1) < 0 then setVolume(1, 0) end
if getVolume(2) < 0 then setVolume(2, 0) end
if getVolume(3) < 0 then setVolume(3, 0) end

--[[
this is of course completely unnecessary as the volumes are automatically adjusted with the global volume ...
you could have used a similar method as this example to create a global volume function - pre v3.8!
