Hi there
So I'm trying to alter gravity in a dop based on the frame number. I've got it key framed at the mo but I'd rather be able to use the expression.
I thought the correct syntax would be
(if($F>=30),9,0) entered into the gravity y field
meaning if I'm at frame 30 or above gravity is 9 else it's 0.
but this doesn't work?
Can someone please give me the correct syntax?
thanks
Nigel.
vex expression if syntax?

Hi
The pattern is: “if(expression, true_value, false_value)”. You have misplaced one parenthesis after the expression statement.
So it needs to look like this: (if($F>=30,9,0))
