Expression for Blending Position
Hi everyone!
I’m wondering if there’s an expression that will allow me to blend between two positional inputs. For instance, in Cinema4D, there is an XPresso node called “Mix” that receives two inputs and allows the user to blend between the two. I’ve used it for “keyframable parenting” in the past, so it can be extremely handy!
Is there anything like this for AE? If I haven’t done the best job of explaining it, please let me know and I would be more than happy to elaborate.
Thank you!

I’m sure if this is what you’re after, but this expression would give you a position somewhere on the line between Layer 1 and Layer 2, depending on the value (0-100)of a slider on the layer with the expression.
s = effect(“Slider Control”)(“Slider”);
p1 = thisComp.layer(“Layer 1”).transform.position;
p2 = thisComp.layer(“Layer 2”).transform.position;
linear(s/100,p1,p2)Dan

Dan,
This is EXACTLY what I needed! I knew you’d come through for this one (as always)!
Thank you so much!

PS – If I wanted to go uber-crazy with this, could I put your ToComp expression in the place of p1 or p2 and simply link the target layers to the first line in the ToComp code?
Thanks!
c=this_comp.layer("child");
c.to_comp(c.anchor_point)

Sure. I think I’d do it like this:
s = effect(“Slider Control”)(“Slider”);
L1 = thisComp.layer(“Layer 1”);
p1 = L1.toComp(L1.anchorPoint);
L2 = thisComp.layer(“Layer 2”);
p2 = L2.toComp(L2.anchorPoint);
linear(s/100,p1,p2)Dan

hey Dan Can it be shape layer Path instead of position?

I’m guessing you might be talking about something like this, but it only works if you have CC 2018:
s = effect(“Slider Control”)(“Slider”).value/100;
L = thisComp.layer(“Shape Layer 1”);
p = L.content(“Shape 1”).content(“Path 1”).path;
L.toComp(p.pointOnPath(s,time))Dan
