Hi Miguel,
First, as far as I know, it is impossible to do multi-thread using Lingo.
However, it is possible to do multi-thread using Xtras beacause Xtras are
made with C/C++ and Win* allows to do multi-thread application (for
examples, see beginthread in MSDN).
There is a way to simulate multi-thread in Director. It is not real
multi-threading and it's going to work in the Director's thread, I call it
more "call-back functions". For example, you can use the "idle" method and a
stack (ie: a priority list) to store the working functions. I don't think
it's useful to do that since it's not real multi-threading... Anyway, here
is an example:
-- Global script
global myStack
on startMovie
-- You can dynamically fill this list which is the stack.
myStack = [[#wrk: "wrkFct1()", #cb: "cbFct1()"], [#wrk: "wrkFct2()", #cb:
"cbFct2()"]]
-- You can eventually use priority. If you want a method to be executed
first, put it
-- in the beginning of the list (HIGH PRIORITY) and vice-versa.
end startMovie
on idle
if myStack <> [] then
do string(myStack.getAt(1).getProp(#wrk))
do string(myStack.getAt(1).getProp(#cb))
myStack.deleteAt(1)
end if
end idle
on wrkFct1
a = 1
b = 5
return a + b
end wrkFct1
on cbFct1
put "Thread 1 done!"
end cbFct1
on wrkFct2
a = 4
b = 6
return a + b
end wrkFct2
on cbFct2
put "Thread 2 done!"
end cbFct2
on addThread1
myStack.add([#wrk:"wrkFct1()", #cb:"cbFct1()"])
end addThread1
on addThread2
myStack.add([#wrk:"wrkFct2()", #cb:"cbFct2()"])
end addThread2
-- End script
It is obvious that it's not real multi-thread, but it should work fine as a
"workaround".
Have a nice day,
Jonathan
