Animating a switch between expressions in one layer
Hi everyone ☺
Here’s what I’m trying to accomplish:
I got one layer in one comp.
i would like this layer to take it’s position from another layer that is in another comp.Up to this point I’m good. here is where it gets tricky –
In the middle of the animation i would like my layer to switch it’s position source (the one mentioned above) to another source (a different layer that is in a different comp). and i would like to accomplish this without splitting or duplicating my layer. i would rather use a checkbox control / layer control / slider control or any other solution you might think of. as long it’s animatable.
I’ll try to simplify it:
White Circle is in comp 1
Red Circle is in comp 2
Green Circle is in comp 31-5 seconds – White Circle takes it’s position from Red circle.
no problem!5-10 seconds – white circle stops tacking it’s position from red circle and switches to green circle.
???Rules for the switch:
1. the switch needs to happen in a manner that i can animate.
(checkbox control / layer control / slider control or any other solution you might think of).
2. the expression takes place in one layer that isn’t splited or duplicated – a switch between expressions in one layer.Thank you all very much 🙂

Hi,
If you create a slider on your white circle layer, you can put this expression for the position property (you can still keyframe your position if you need to) :
var a = comp(“Comp 3”).layer(“Shape Layer 1”).transform.position;
var b = comp(“Comp 2”).layer(“Shape Layer 1”).transform.position;
var c = effect(“Slider Control 1”)(“Slider”);transform.position + ((a*c/100) + (b*(100-c)/100))/2
Hope this helps,
Cheers ! -
Works like a charm!
Thank you 🙂
