Tweening to a Relative Position using a Variable in TweenMax

This isn’t too complicated, but it’s something I hadn’t come across until a few days ago. If you want to tween an object relatively, but the new value changes and needs to be a variable, just cast it as a string.

[js]// Your everyday absolute tween that moves movieclip_mc
// to 100 on the x axis, taking one second to do so, 1, {x:100});

// A relative tween that moves movieclip_mc to a
// position on the x axis 100 units/pixels greater
// than movieclip_mc’s current position, 1, {x:"100"});

// An absolute tween like the first, but passing in
// the new value with a variable, 1, {x:newX});

// A tween that casts the variable as a string,
// thus making it a relative tween, 1, {x:String(newX)});[/js]

If you’re not using TweenMax/TweenLite, do yourself a favor and give it a try.

  1. Thanks for listing this. Being self taught in Actionscript, it’s really tough to know what tags are available for me without being told. I wouldn’t even thought there would be one for relative tweens.
