Wouldn't it be nice to create a reference by path. Here is a solution in AS1.
Download
//via an object property
a = {}
a.x = 23
pathRef('x','_level0.a.x')
trace(x) //23
x = 45
trace(x) //45
trace(a.x) //45
//via a movieclip property
pathRef('x','_level0._x')
trace(x) //0
x = -100
trace(x) //-100
trace(_level0._x) //-100
Better still as a pathRef is always created by path so if you swap the object it is pointed at, the reference will still work. With pure references this would break.
a = {}
a.x = 23
pathRef('x','_level0.a.x')
trace(x)
//redefine a
a = function(){}
a.x = "I am a function now!"
trace(x) //I am a function now!
Too fun. This one has 1000's of uses from remote controlling objects to reference resilient classes.
As always send me any bugs or changes in the code.
Cheers,
