Get original value of a property ‘before’ the expression is executed!

[Dan Ebberts]

You might be able to re-work your expression so that you can apply it to the position property of a Transform effect. That will leave that actual Positon property unaffected so you can access it from the other layer.

Hey Dan,

No dice I’m afraid; its that 3D globe names thing again.

The layer has 3D turned on and an expression applied to move its position into a sphere.

I need to be able to get the x and y of the layer before the expression was applied.

I’m basically setting up a template project so you just select the countries name and the globe will spin around to that country (for Ole’s site)

I wish there was a way of getting values out of expressions to other layers at particular points in the expression!

Say; ‘get value for x and y at line 1 of this expression on layer X’!

I think I’ve gotten around it…

I don’t need the new value to start straight away, so I used a ‘linear(t, tMin, tMax, value1, value2)’
to map the values from original to new in the first frame.

Then in the second layer I used the ‘valueAtTime()’ to get the value at 0 time.

Seems to do what I wanted

WooHoo! bring on the weekend

Ah yes, I forgot about the old negative time trick. You can map the target layer’s pre-expression position into negative time like this:

if (time <= 0){ valueAtTime(-time) }else{ // your expression goes here } Then retreive it from the other layer like this: comp("main comp").layer("target").transform.position.valueAtTime(-time) Dan
