Library requires library not working

[sethmachine]

Hi,

Suppose we have 2 libraries, A and B.

Library B requires Library A, as Library A fills up a special table that B needs to do its work correctly.

library A initializer init
globals
  integer array INTS[5]
endglobals

private function main takes nothing returns nothing
  set INTS[0] = -555
endfunction

private function init takes nothing returns nothing
  local timer t = CreateTimer()
  call StartTimer(t, 1.0, false, function main)
endfunction

endlibrary

and our second library

library B initializer init requires A

globals
endglobals

private function init
  call print(I2S(INTS[0])) //this should print "-555"
  //instead it prints "0"
endfunction

endlibrary

So, even though B requires A, somehow B's init fires off before A fills up its data structure. This is impossible given the documentation I've read, which promises that all of B's work, etc. will be started only AFTER A.

Or is the timer somehow messing things up? (should be in manual...)

Yes, of course the timer. It starts a new thread that the parent one has no access of.

Here's the run order according to your code

A.init -> B.init -> A.main


Your initializers run perfectly. It's not like an initializer is going to wait for a timer

Silly of me to ask. I was thinking (wrongly) that it would have to wait for the timer to finish before A.init gave up its thread, but I guess the timer actually sleeps it for whatever amount of time, and then moves onto the next job, by which time the data structures are made out of place. More efficient, because otherwise we're waiting a second doing nothing.

This would all be so much simpler if dialogs could be made in initializations. I ended up just calling the init function of library B inside A's main function.

The timer runs on it's own, so your init for A assumes that it's work is finished right after that StartTimer call... If functions wait for timers, a lot of things doable right now will suddenly fail...
