Hi
I am trying to replace the audio.loadSound function with a new one to delay the audio loading (using timer.performWithDelay. The following code doesn´t work but demonstrates what I am trying to do (its just an example):
-- define some globals that can pass parameters
auli=0
posi=0
auls= {}
poso={}
-- function to distribute audio loading over time (to prevent transitions from hanging)
function audioloadSound(auli)
-- audioloadSound(sound,handler)
auls[#auls+1]=auli
poso[#poso+1]=timer.performWithDelay ( #auls\*100,
function(event)
local param=event.source.poso
poso[param]=audio.loadSound(auls[1])
print("loaded "..auls[1].." in "..param)
table.remove ( auls,1 )
return poso[param]
end , 1)
poso[#poso].poso=#poso
print("called:"..#poso)
return poso[#poso]
end
mySound[1]=audioloadSound("explosion.wav")
mySound[2]=audioloadSound("popsound.wav")
mySound[3]=audioloadSound("bird.wav") The main problem here is that the audioloadSound function needs to pass back a parameter which is the sound handle/reference. When the function is finished, the audio isn´t loaded yet, so there is no handler to pass. My though was that “return poso[#poso]” would return a reference to the variable which later would be updated as “return poso[param]” is executed, but it is not happening.
So the question is: Is there a way to pass the variable reference “mySound[1]” to the function so that I can update that variable on a later time? Do I need a timer event to do that or can it be done in the loading function? I rather not hardcode any variable, so a way to directly reference handles (or copy the reference) would be nice…
Hope anyone can help.
