Switching Variables

[hmvince]

Hi guys,
You guys probably think this is simple, but I would just like to know how one would go about switching 2 variables around. For example if I have

a = 5;  b = 3;

Then use the switch function and get:

a = 3;  b = 5;

is there any such thing?
thanks for your time.

IGNORE THIS POST, BECAUSE I JUST TRIED IT, AND IT'S NOT WORKING, LOOK AT THE NEXT POST

I think there is one, but I can't remember. Although, why not make a custom function for that?

function switch_vars(varA, varB){
    holder1 = varA;
    holder2 = varB;
    varA = holder2;
    varB = holder1;
}

Then, use this to switch 2 variables:

switch_vars(a, b);

I haven't tested it yet, but hopefully, it should work

What the above code did, was to make a function where varA and varB can be something you type yourself, like for instance, a and b variables, and then, when calling the function to execute its codes, varA and varB are replaced with the custom variables defined by you yourself. But the problem was that varA and varB, which would refer to variables a and b, didn't take the names a and b, but rather those variables' values, so when storing their values at the beginning of the function inside two other variables, their values were stored, but when switching their values, varA and varB weren't referring to a and b variables, but rather their values, and we don't have any variables named 3 or 5. So, by instead using strings for the variable names, we can refer to the actual variables, so change your function to this:

function switch_vars(varA, varB){
    holder1 = _root[varA];
    holder2 = _root[varB];
    _root[varA] = holder2;
    _root[varB] = holder1;
}

and to use it:

switch_vars("a", "b");

always remember quotes around your variable name in the function, otherwise it won't work
