What is the prefered way to iterate through a table while checking for
some condition and selectively removing fields? I seem to recall that
directly setting them to nil caused the next() function to get confused.
This is what I'm doing now. It works but it seems there should be a
better way.
local removeList = {} -- list to hold values to remove since we
can't remove in the loop without messing it up
for k, v in pairs( self.eventList ) do
if v.time <= self.time then
v.event( self )
removeList[ k ] = k
end
end
for k, v in pairs( removeList ) do
self.eventList[ k ] = nil
end
