So I tested the index suggestion and it seems to work… Here’s the code:

x = thisComp.layer(“Name of the Layer”).effect(“Name of the Slider”)(“Slider”)

if (x >= index) {100} else {0}

So I basicly changed ‘the arbitrarly chosen digit’ into ‘index’ which correlates to the layer’s index.(how ’bout that :p)

And I added an ‘is equal to’ sign, so you can put the exact value in :)

Not the next moonlanding or a mission to mars, but it saves you some work… :p

This is a useful code for “Flash” layer opacity:

maxkeys=thisComp.layer(“control”).effect(“Slider Control”)(“Slider”).numKeys;
choose=0;
radius=0.1;
choose = thisComp.layer(“control”).effect(“Slider Control”)(“Slider”).nearestKey(time).index;

if (choose!= 0) {
choosekeytime= thisComp.layer(“control”).effect(“Slider Control”)(“Slider”).key(choose).time;
if ( time < choosekeytime )
{
// linear (time, choosekeytime-radius, choosekeytime,0,100);
// ease (time, choosekeytime-radius, choosekeytime,0,100);
ease_in (time,choosekeytime-radius, choosekeytime,0,100);
// ease_out (time, choosekeytime-radius, choosekeytime,0,100);
} else
{
if (time <choosekeytime+radius)
{
// linear (time, choosekeytime , choosekeytime+radius,100,0);
// ease (time, choosekeytime , choosekeytime+radius,100,0);
// ease_in (time, choosekeytime ,choosekeytime+radius,100,0);
ease_out (time, choosekeytime, choosekeytime+radius,100,0);
}
}
} else
{
0;
}

You don’t need a lot of keyframes. This way is more flexible.

Sorry my english. :(

damn, I hate expressions!
