Hey guys!,
I am trying to follow this tutorial of a code/characters raining matrix effect. I would like to tweak it and create a line of text (the word "Dystopia" instead of random chracters; meaning that each point would first create the letter "D", then "Y", and so forth and create the rain effect of many words saying "Dystopia". I tried to tweak this line of code (from the attached image) but I am by no means experienced in coding and I am not sure what I am doing. If someone could help me out with the code or point me in the right direction it would be very much appreciated. Thank you for your time!!

You could try something like this to replace your s@character generation vop.
You'll want to reduce your particle Life Expectancy from 100 seconds to something lower like 4 seconds. Life Expectancy controls speed of character change with this setup. To make the strands change at different rates, try a non-zero value for Life Variance on the popsource1 node.
Place this code in a point wrangle.

Place this code in a point wrangle.
// Create an array of characters from a string. string letters[] = split("D,y,s,t,o,p,i,a,",","); // Get array length. int l = len(letters); // Generate an index into the array based upon particle age. int index = int(fit(@age,0,@life,0,l)); // Alter starting index randomly for each point. int offset = int(fit01(rand(@id),0,l)); index += offset; // Make sure index isn't longer than array length. while(index>=l){index=-l;} s@character = letters[index];
