Accessability of the point number attribute in the VEX "point()" fucntion

[fatboYYY]

Hey guys,

I've been wondering this for quite some while, but always managed to find a workaround. I am not sure if I will be able to find one this time. 

As an example:

Why does the test attribute not reflect the pointnumber attribute here? (Any input-geo with points is sufficient)

for(int i = 0; i <npoints(0); i++)
{
if(@ptnum == point(0,"ptnum",i))
i@test = 1;
}

Am I just calling the pointattribute wrong here, or is it not possible to get the pointattribute back through the point() function. What other option do I have to get return the pointattribute in a custom loop?

Thanks in advance.

I tried with

i@test = point(0, "ptnum", @ptnum);

and it does return 0. Why ... have no Idea, but since you already know the number of the point you are calling, I don't see the point of requesting the point number.

I suppose the reason is that @ptnum is not a real point attribute but a global point wrangle variable.

but if you really need to know the point number that way, you can set different attribute beforehand (in separate wrangle)

i@id = @ptnum;

and use @id instead @ptnum
