I've done tests before, using sendAllSprites() is about 7 times faster
than using repeat with i = 1 to the last channel. Seems
sendAllSprites performance is also depended on the amount of sprites
with behaviors. SendAllSprites on a frame with only a few behavior
takes almost no time to perform. Using repeat with i = 1 to the
lastchannel will take nearly the same amount of time regardless how
many sprites have behaviors.
By counting using the last channel, you will need 3 loops to get your
code correct:
repeat with k = 1 to the lastChannel
repeat with l = 1 to sprite(k).scriptInstanceList.count
repeat with m = 1 to sprite(k).scriptInstanceList[l].count
if sprite(k).scriptInstanceList[l].getPropAt(m) = #myBuiltInCursor then
sprite(k).cursor = sprite(k).myBuiltInCursor
else
nothing
end if
end repeat
end repeat
