Combining 2 expressions on a slider control
Hi I’m having trouble getting 2 expression to work together on a slider control. Thanks to the wonderful Dan Ebberts, I’m using this expression to randomize a bunch of stills in a composition (https://motionscript.com/expressions-lab-ae65/random-stills.html). My trouble is whenever the slider hits a value on 1, no stills are shown. I’d like to add to the expression so that the minimum value never goes below 2. Dan’s expression looks like this:
duration = .125; //length of each cut (seconds)seed = Math.floor(time/duration) + 1;
seedRandom(seed,true);
Math.floor(random(1,index));I tried adding this line of code after:
clamp(value, min=2, max=255)But it doesn’t work. What am I doing wrong? Or is there a better way to do this?
Thanks!duration = .125; //length of each cut (seconds)seed = Math.floor(time/duration) + 1;
seedRandom(seed,true);
Math.floor(random(1,index));clamp(value, min=2, max=255)

You can change the random() min parameter to 2 like this:
Math.floor(random(2,index));Or you can check the value with an if statement:
duration = .125; //length of each cut (seconds)seed = Math.floor(time/duration) + 1;
seedRandom(seed,true);
randomValue = Math.floor(random(1,index));val = (randomValue < 2) 2: randomValue;

Ah…
It worked changing
Math.floor(random(2,index));Thanks again!!!
