Hi,

You can use the setpointattrib function:

Hi,

would something like this work?

In a point wrangle:

// user parameters
int seed = chi("seed");

// fetch the "a" attribute from point 0
float a = point(0, "a", 0);
a = rand(a+seed*123.6);
@a = a;

mandrake0

// user parameters
int seed = chi("seed"); // Getting a seed Value


float a = point(0, "a", 0); // fetch the "a" attribute from point 0
a = rand(a+seed*123.6); // Creating a random value from 0 to 1 with a seed value from a + seed + 123.6
@a = a; 

why do you want to get one point attribute value for just add to a random seed value that returns a random value?

Andr made a post exactly what i was thinking you have mean.

i think we/i misunderstand your question.

made a example file

I'm sorry, I'm a bit confused by your reply. It looks to me like you think that I started the thread, which I didn't. I read damonmaster's original question, and the code snippet he then posted above (that is where my a = rand(a+seed*123.6) comes from, more or less). And then I posted a possible answer. My question was addressed to damonmaster to check if it was what he was looking for/something he could use. Sorry again, but I must have overlooked Andr's answer, which is really similar, before I added my own.

Cheers,
Dag

My situation is that each time the value of @a is the result obtained from the last loop, how can I copy the result of the loop to other points in the same wrangle? I know this would be very simple just using two wrangle nodes!

int success = 0;
f@value = pointattrib(0,"a",0,success);
i@success = success;
