thanks a lot for this nice small script! I just had to cut client`s banner 10K down - done in ten minutes including googling for your site : -)

Perfect. And only 24 min after the question.
I’ll make a donation tonight, you really deserve it.

Tim, all you need to do to treat your variables as strings is wrap them in “String()”, like this:

TweenLite.to(string_spark,0.2,{_x:String(spark_move)});

Hi Jack.
I use your tween class in every project (I should pay royalties :P), and it works perfectly in most cases. But this time, I’m stuck with a simple, little, but annoying problem :

I need to tween various properties of hundred of movieclips with random values. As usual, it works perfectly, but I can’t use a variable as a relative value. Let me show you the AS2 code excerpt :

// Here are my random values
spark_size = Math.round(Math.random()*50)+50;
spark_alpha = Math.round(Math.random()*50)+30;
spark_rotation = Math.round(Math.random()*360);
spark_move = Math.round(Math.random()*10);

// Here is the tween, using these variables
TweenLite.to(string_spark,0.2,{_x:”spark_move”, _alpha:spark_alpha, _rotation:spark_rotation, _xscale:spark_size, _yscale:spark_size, overwrite:false});
}

As you can see, i just want to wiggle my sparks using random relative values, using the spark_move variable. But the quotation marks don’t enable me to use a variable, only integers.

If you have any idea that can solve this issue…
Many thanks.

szataniol, in order to keep file size down, TweenLite doesn’t have an “isTweening” feature, but TweenMax does! Check out http://www.TweenMax.com
