Hi,
I am looking for a 2 ways to animate a lot of layers/texts...
I would like to know about: first using expressions, second using TC Particular.
First:
I am using this expression:
tMin = .25; //minimum segment duration
tMax = 1.0; //maximum segment duration
minVal = [0.1*thisComp.width, 0.1*thisComp.height];
maxVal = [0.9*thisComp.width, 0.9*thisComp.height];
end = 0;
j = 0;
while (time >= end){
j ++;
seedRandom(j,true);
start = end;
end += random(tMin,tMax);
}
endVal = random(minVal,maxVal);
seedRandom(j-1,true);
dummy = random(); //this is a throw-away value
startVal = random(minVal,maxVal);
ease(time,start,end,startVal,endVal)
It moves around the object/text randomly from one to next position. How can I define the starting position. I would like to have control of the movement first (by using keyframes or moving along a path) and at a certain time make the object move randomly / drifting.
Second: I would like to achive the same with Particular.
The first part of the movement of the particles (not the emitter) should be straight upwards. After a while (let's say half the screensize), the particles should start to move randomly in space / drift.
I don't understand how to do it. I have a Point-Emitter. Using direction "Directional" makes them drift out of the Composition. Moving along a path makes them stop at the end of the path and "Air Resistance" can't be changed with keyframes. I am not very firm with Particular I must admit...
Thanks!

As far as the particle stuff goes, you probably have to get into the new Stardust plug-in which allows more control via its nodal flow graph and including conditional triggers. Same for any 3D program's particles like Thinking Particles and X-Particles in Cinema 4D, PFlow in MAX, Houdini's particles and so on. Some things simply can't be done in a simple manner, least of all in AE. the expression stuff can easily be modified by including the "value" function and tying the parametric definitions to a slider with a multiplier to modulate their intensities.
