Repeat After Effects expressions

[Dan Ebberts]

Try it this way:

rot = transform.rotation%90;
if(rot < 45)
  ease(rot,0,45,10,100)
else
  ease(rot,45,90,100,10)

Thank you!! It works perfectly. Why did you write &90?

[Dan Ebberts]

You mean %90 ? % is the modulus operator in JavaScript. It returns the remainder from a division operation. So, for example 108 % 90 would give you 18. In this case, it keeps all your angles in the range from 0 to 89.9999… degrees.

Nice! Thank you so much 😉

Hello again Dan,

How can I simplify this code? It is similar to the one last sent.

Thank you so much, I’m learning a lot!

rot = transform.rotation;
tsx = 360;
// 1. 360
if(rot>=-30 && rot<=30) ease(rot,-30,30,effect("Color Control 2")("Color"),effect("Color Control")("Color"))
else if(rot>=60 && rot<=120) ease(rot,60,120,effect("Color Control")("Color"),effect("Color Control 2")("Color"))
	else if(rot>=120 && rot<=150) effect("Color Control 2")("Color")
else if(rot>=150 && rot<=210) ease(rot,150,210,effect("Color Control 2")("Color"),effect("Color Control")("Color"))
else if(rot>=240 && rot<=300) ease(rot,240,300,effect("Color Control")("Color"),effect("Color Control 2")("Color"))
	else if(rot>=300 && rot<=tsx-30) effect("Color Control 2")("Color")
// 2. 360
else if(rot>=tsx-30 && rot<=tsx+30) ease(rot,tsx-30,tsx+30,effect("Color Control 2")("Color"),effect("Color Control")("Color"))

There has to be a way to vastly simplify the code, but it’s hard to tell from looking at it what it’s supposed to be doing exactly. There seem to be gaps, like from 30 to 60, and from 210 to 240 where no action is defined. If you could describe what you need it to do, it might be easier to start there.
