Hello,

I am new to Houdini and not grasping how attributes work.

First I created “Add” node to create a point.

Then I have created attributes in “Attribute Create” node called @posx and @frameno (@frameno value is $FF).

I then created a “Point Wrangle” node with the following vex code:

if(@frameno < 100){
@posx = @frameno;
}


The @posx attribute indeed increments, but once @frameno gets past 100, the value returns to zero. What is the method to have these attributes retain their values?

Thank you,
Caesar

@posx is not defined outside the if statement, that mean it's initialized to default value that is usually zero (or random value in some programming language).

use:
float max = 100;
@posx = max-1;
if(@Frame < max){
@posx = @Frame;
}

Maybe a solution, too :-?

Please have a look here, too:

Thank you gentlemen - I will give it a try when I get home.
