flashVars Boolean

[bumblingTiki]

Hello,

Working on a site that uses flashVars. I was able to work with number variables no problem, but I have a boolean value that is proving to be more tricky than I anticipated. Any help would be appreciated!

the HTML Param is "isMetal"

I've tried a few things and this is what I have now...

var isMetal:Boolean;

function init():void

{

// true if 'isMetal' is set to '1'; false otherwise

isMetal = loaderInfo.parameters.isMetal != "0";

}

Then I try to use the boolean to pick between filter settings and layer blend modes... unfortunately, it always uses what happens after "else."

if(isMetal != 0)

{

color = new AdjustColor();

color.brightness = 100;

color.contrast = 10;

color.hue = 0;

color.saturation = -100;

loadLogo.blendMode = BlendMode.SCREEN;

}

else

{

color = new AdjustColor();

color.brightness = 0;

color.contrast = 10;

color.hue = 0;

color.saturation = -100;

loadLogo.blendMode = BlendMode.MULTIPLY;

}

all flashVars are strings.  use it as a string:

if(isMetal!="0")

{

etc

I was reading online that I had to recast the boolean and that is was a bad idea to pass "false". Long story short...I was over thinking!

Thanks for your help!

you're welcome.

you can pass "false" or "true".  you just have to remember that it's a string and not a boolean:

var s:String = "true";

if(s=="true"){  // good

etc

if(s){  // not so good. when s="false" (or when s is anything other than an empty string, this resolves to true.

etc

and, you definitely don't want to try casting a string as a boolean because you probably won't like the results:

var s:String="false";

var b:Boolean=Boolean(s):

trace(b);  // output: true.  again, when evaluating a string for true or false, all non-empty strings resolve to true and the empty string ("") resolves to false.
