wrangle point attribute

[MENOZ]

hello, 

I'm trying to store the values of an attribute in a new one.

 

after creating a vector attribute test in vop with a noise I want to copy it on v@d in wrangle but..

 

v@d=@test;

just takes the first index of test

 

v@d=point(0,"test",@ptnum);

i have to use this to get the correct values

 

but at the same time

v@Ptemp=@P;

works correctly, even with normals and color.

 

I tried to change the type fo the attributes in wrangle using setattribtypeinfo but it looks like it doesn't makes any difference.

 

can anyone explain the logic behind this?

 

attached a simple example file

v@test;

v@d = @test;

 

OR

 

v@d = v@test;

 

 

 

All other @ references are cast as float. To manually specify the VEX datatype for an attribute, you must add a character representing the type before the @ sign. For example, to cast the foo attribute as a string, you would use s@foo.

 

That's the reason for your issues. When that happens, only the X component of a vector is used.

 

@P on the other hand is internally recognized as a vector. So you don't need the v@P notation. Altho I usually write this anyway.
