Hi,
i prefer default-values using metatables:
local _snddefaults = {__index = {loop = true}}
setmetatable(sounds[1], _snddefaults)
...

Hello,
Simple question here:
sounds =
{
{ name="beep", file="./media/beep.wav" },
{ name="bloop", file="./media/bloop.wav", loop=false },
}
If I want the parameter "loop" for a sound to default to true when
unspecified I thought I would write:
shouldLoop = sounds[1].loop or true -- (nil or true) => true
but then it doesn't work for the second entry:
shouldLoop = sounds[2].loop or true -- (false or true) => true
This was a bit of a surprise, since (nil or false) => false.
What's the elegant idiom for this situation?
