vex expression

[tinboy]

Hi guys

The following reads when a particle comes in a group and creates an attribute assigning the frame number when it came in the group for it:

Attribute Node:

Default: -1

Value: if(ENTER_RELEASE == -1, $F, @ENTER_RELEASE)

 

I'm trying to re-write it as a vex expression  in a popwrangle node as follow:

@enter_release = -1;

if(@enter_release==-1)@enter_release = @Frame;  
else @enter_release = @enter_release;

It displays the frame number when the particle came into the group but instead of displaying the same frame number when it came in it keeps on displaying the current frame number the whole time.

What am I missing here?

I've tried writing it like this and it still doesn't work:

@enter_release = -1;

if(@enter_release==-1)  {
    @enter_release = @Frame;  
} else {
    @enter_release==@enter_release;
}

Because you are setting enter_release = -1 at the beginning, the if-statement will always return true.

use

float @enter_release = -1;

to set the default.
