  Color if expression

  Posted by Alexander Weil on November 23, 2016 at 5:17 pm

  hey
  is there any way i can control the color with an if expression? it has to check that the value color is for example Blue, if that is true it has to change to a color i defined with a color controller, but if it is not it should use the value color
  here is what i tried but it did not yet work:

  
cColor = effect("check Color")("Color"); //the color it should check
gColor = effect("Global Color")("Color"); //the color it should be if its the checked color
vColor = effect("Wales")("Color"); //the value color

  if (vColor == cColor){
  gColor
  }else{
  vColor
  }

  Hi!
  Color in AE is an array [red, green, blue, alpha]. And you can’t compare two arrays using “==”. More info here. Instead of this you need to check every value in array separately. Also you don’t need to check alpha value (the last value (id = 3) in array). So this code should work for you:

  cColor = effect("check Color")("Color"); //the color it should check
gColor = effect("Global Color")("Color"); //the color it should be if its the checked color
vColor = effect("Wales")("Color"); //the value color

  if ((vColor[0] == cColor[0]) &&
(vColor[1] == cColor[1]) &&
(vColor[2] == cColor[2])){
gColor
}else{
vColor
}
