Control a symbol timeline from another symbol timeline on specific condition

Question

Hi! I have 8 animated symbol that plays on clicking over them on the main stage and i want, for example, that if symbol 1 animation is complete and i click on symbol 3, symbol 3 plays forward and symbol 1 plays on reverse and vice versa just like this: http://www.framefarm.net/eugenio/edge/example/example.html
please help!

Answer 1

I put together a Composition that I think does what you're asking. it's not elegant, but it works.
in the timeline of Symbol_1
place stop() triggers at the start and end
in the same triggers, set a Symbol variable that states whether the animation has finished i.e. sym.setVariable("isDone", "false");
place a trigger on the rectangle to play() or playReverse() depending on an if() statement about the variable
in the timeline of Symbol_3
place stop() triggers at the start and end
in the same triggers, set a Symbol variable that states whether the animation has finished i.e. sym.setVariable("isDone2", "false");
place a trigger on the rectangle to:
declare 2 new variables, which use sym.getVariable() to get isDone and isDone2 as above,
play() or playReverse() depending on an if() else if() else if() statement about both variables
I used the relative string to get the local variable and absolute string to get the variable from the other Symbol, i.e.
var myVariable = sym.getComposition().getStage().getSymbol("Symbol_1").getVariable("isDone");
var myVariable2 = sym.getVariable("isDone2");
I can send you the entire code if that helps.
