  Logical operators in expressions

  Posted by Vadik Zhuk on May 2, 2013 at 12:57 pm

  Is there some logical operators like & (AND) or ! (OR) in use with AAE expressions? For expample: I need to change layer opacity to 100 if opacity of 3 other layers is 0. Expample expression (not working one, just to illustrate more accurate what exactly I mean) is below.

  if (thisComp.layer("lang").effect("Layer Control")("Layer").index == index) 100
else
if (thisComp.layer("ENG").transform.opacity == 0) & (thisComp.layer("ESP").transform.opacity == 0) & (thisComp.layer("KOR").transform.opacity == 0) 100 else 0

  The AND and OR operators are: && and || respectively. Here’s the complete list:
