Expression problem, I need to understand why
This expression is not working for me and I know it should be. Can anyone tell me what i’m doing wrong. In the comp I’m using Particular to trace masks and this expression is supposed to prevent the lines between masks.
Adobe gives me this error:
After Effects warning: Expected: ;
Expression disabled.Error occured at line 1.
Comp: ‘name’
Layer: 2 (‘particular’)
Property: ‘Particles/sec’I see where the error is but I don’t understand why there is an error.
It’s based off of this tutorial: ae.tutsplus.com/tutorials/motion-graphics/quicktip-fast-and-easy-text-writing-with-particular/
He uses the same expression flawlessly and I used it identically.-E

You didn’t include the expression you’re talking about in your post.

MR. Wilczynski
I have tried this for you and I got the solutionWhile Typing the first line
“x=…..” x is a small cap letterBut second time He types Capital x : “X”
So just change the Small cap “x” “capital “X” in the first line and it will work 🙂Vishesh Arora

Sorry. Here is the expression X = effect(“Checkbox Control”)(“Checkbox”) if (X = = 0)0 else (effect(“Particular”)(“Particles/sec”))
It’s still not working for me.

[Erick Wilczynski] “Sorry. Here is the expression X = effect(“Checkbox Control”)(“Checkbox”) if (X = = 0)0 else (effect(“Particular”)(“Particles/sec”))”
You have to separate the different operations with semi-colons like this:
X = effect("Checkbox Control")("Checkbox");
if (X == 0) 0;
else (effect("Particular")("Particles/sec"));
Also, I’m quite sure that you’ll need the == operator without any spaces in between the =’s. == (comparison) is a wholly different operator than = (assignment) and two =’s separated by a space may be seen as two assignment (=) operators instead of one comparison (==) operator.
