linear,wiggle, and opacity oh my
I’m getting a bit stomped as I continue to grow with expressions. I think that I’m missing a few pieces of the puzzle here. I have come up with a couple expressions(derived from) and am troubleshooting them.
My attempt with expression 1, is to have object A start moving when time is greater than two seconds. Instead it just pops into place.
In expression two, I have stumbled across the conditional expression for opacity and am just wanting to know why the expression I’m attempting to use fails when applied to opacity(derived from a similar expression applied to scale).
Thanks for any insight into these topics
///expression 1\\\Assigned to Position:
if (time > 2){
linear(time,value,[960,100])
}else{
value
}expression 2
fadeIn = linear(time,inPoint+.5,inPoint,0,100);
fadeOut = linear(time,outPoint,outPoint - .5,100,0);fadeIn+fadeOut

For the first one, you need to define either a speed, or a duration. The speed version would be something like this
if (time > 2)
value + [50,50]*(time-2)
else
valueYour fade in/fade out would be more like this
if (time < (inPoint+outPoint)/2)
linear(time,inPoint,inPoint+.5,0,100)
else
linear(time,outPoint – .5,outPoint,100,0);Dan

As always Many Many Thanks! I’m going to have a bit of fun trying to understand how these particular expressions work. Again THANKS!!!, and off to expression land I go!
