Object in Z space w/ Random Velocity Part 4
There was actually a question in that last post, that might have been over looked (it’s based off of the third, z position, random velocity animation script you gave me [I’ve included it at the bottom of this post for reference])–Now, and this is the last time on this, I swear:
How would it be scripted if I wanted the layers to start from zero z, animate in positive z, each at that random velocity, then switch at second 1.5 to come back to zero z–but, now, at zero z (which would be 3 seconds) their random velocity changes to a much, much smaller range (basically they drift ever so slightly into -z, then, say at 4 seconds or 1 second later they switch back to the original, greater, random velocity range and continue on in -z and out of frame?
so:

How about this?
switchTime1 = 1.5;
switchTime2 = 3.0;
switchTime3 = 4.0;minV1 = 100; // min velocity (pixels per second)
maxV1 = 500;
minV2 = 10;
maxV2 = 50;
seedRandom(index,true);
V1 = random(minV1,maxV1);
V2 = random(minV2,maxV2)
if (time < switchTime1){ value + [0,0,time*V1]; }else if (time < switchTime2){ value + [0,0,(2*switchTime1 - time)*V1]; }else if (time < switchTime3){ value - [0,0,(time - switchTime2)*V2]; }else{ value - [0,0,(switchTime3 - switchTime2)*V2] - [0,0,(time - switchTime3)*V1]; } Dan -
Awesome! Thanks!!!
