  Expression to choose in a list of random angles

  Posted by Sebastien Bruzzo on August 14, 2011 at 11:38 am

  Hello there,

  First please excuse me for my english 🙂

  I want to try something like this :

  1) put a Linear wipe effect on a solid layer and randomly select the wipe angle parameter in a list of 4 possible angles (90, -90, 0, 180)

  2) suppose that the layer duration is 5 seconds, and i have 100 or 200 similar solids in my comp, i want the Linear wipe effect to start 3 frames before the out point of every layers.

  Thank you very much for helping me ! 🙂

  This should work for the angle:

  seedRandom(index,true);
  90*Math.floor(random(-1,3))

  Try this for wipe completion:

  f = 3;
  linear(time,outPoint-f*thisComp.frameDuration,outPoint,0,100)
