random expression executed once
I have the following expression on a text source:
var myArray = [“beans”,”rice”,”tacos”,”bbq”];
var i = Math.floor(random(myArray.length));
myArray[i]I need a expression to execute one time and not every frame when the playhead plays through the comp. How can I run an expression to execute only at the beginning of a timeline and not on every frame? I don’t see any triggers/events for detecting the first run of the timeline, for example an onEnterFrame handler function that actionscript utilizes.
thnx in advance
var myArray = ["beans","rice","tacos","bbq"];
var i = Math.floor(random(myArray.length));
myArray[i] -

Maybe I missed your point, but why do you want a random function to choose one out of four choices and keep it forever? Why not just pick one manually and assign it and not change it throughout the time?

I have a comp generating particles. I am attempting to customize the look of the particles with animated text. I have attached a second comp to each individual particle to design the animated look and feel. I am using the second comp to design the animated words but I need it to be an array of different words.

seedRandom() is what you’re looking for. Like this:
var myArray = [“beans”,”rice”,”tacos”,”bbq”];
seedRandom(index,true);
var i = Math.floor(random(myArray.length));
myArray[i]Dan
