current value of a tween prop

Go to solution Solved by PointC,

I am wondering is there a way to tell the current value of a tween prop ( say "x") before any tweening.


For example:


gsap.to(".class", { x: "+=100" }


// how to "properly" tell what x is before we add 100


I reckon it is target._gsap[prop], but is it expected to be used like that.


x: (_,t) => { 
      var val = t._gsap["x"];
      val = val ? parseFloat(val) : 0;
      return val + 100 


Is this what the engine does behind the scenes? Is this equivalent to "+="?
