Question

I am trying to reference a shared object (one that saves data), but whenever I try to, I get a crash.

This code works fine:

var var1:Object = { value:1 };
var varRef:Object = var1;

if(var1.value == 1) {
    varRef.value = 50;
}

trace(varRef.value); // outputs 50;
trace(var1.value); // outputs 50;

But when I try to use shared objects, it doesn’t work.

import flash.net.SharedObject;
var iapso:SharedObject = SharedObject.getLocal("purchases");
var varRef:Object = iapso.data.testing;

varRef = 90
trace ("The shared value is " + iapso.data.testing);
trace ("This should mirror it" + varRef);

If you’re able to figure out the issue, please post a fixed version.

Thanks.

Answer 1

You must come from a programming background where pointers can be dereferenced.

In this case, varRef is not varRef = &iapso. Setting its value does not change the value of iapso.data.testing;

Initially, you set varRef as a pointer to iapso.data.testing:

var varRef:Object = iapso.data.testing;

Then, you immediately change it to a constant value object literal 90:

varRef = 90;

This does not set the value of testing to 90 – this changes the value of varRef.

You could set varRef to iapso.data, then set testing as in:

var varRef:Object = iapso.data;
varRef.testing = 90;

Then, the following would produced expected results:

trace(iapso.data.testing); // 90
trace(varRef.testing); // 90
