A miniaudio binding for Defold Engine.
Only APIs used in Aerials are implemented. Refer to api/acaudio.script_api for API usages.
Note: If you want to bundle a Windows Application with this extension, you may need to put a valid MSVCRT.lib file into the lib/x86_64-win32 directory.
You should implement your HitSound system with a Unit Pool like this:
local CreateUnit = AcAudio.CreateUnit
local PlayUnit = AcAudio.PlayUnit
-- 1.Create a HitSound Resource (some_buf is a Defold Buffer)
--
local ResourceCreated, HitSoundRes = AcAudio.CreateResource(some_buf)
-- 2.Create the HitSound Unit Pool
--
local HitSoundUnits, UnitCount
if ResourceCreated then
local UnitCreated, FirstUnit, UnitLen = CreateUnit(HitSoundRes)
if UnitCreated then
HitSoundUnits = {FirstUnit}
--
-- Choose a reasonable filter interval,
-- And set the UnitCount according to it.
--
UnitCount = math.ceil(UnitLen / 50) -- Filter Interval: 50ms
UnitCount = (UnitCount>1) and UnitCount or 2 -- Use at least 2 Units
for i=2, UnitCount do
local ok, u, l = CreateUnit(HitSoundRes)
if ok then
HitSoundUnits[#HitSoundUnits+1] = u
end
end
UnitCount = #HitSoundUnits
end
end
-- 3.Encapsule the Playing Method with the Unit Pool Created above
--
local Which = 1
local function hit()
PlayUnit(HitSoundUnits[Which], false) -- Play the HintSound only once
Which = (Which==UnitCount) and 1 or (Which+1) -- Update the counter
StopUnit(HitSoundUnits[Which], true) -- Let the next Unit rewind to start
end-
