vex Vex - attribute reading warning

[SteveNi]

Hi

So I have some Vex code and I keep getting this warning:

It says "implicit cast from float to int, use explicit cast instead".

Now I know this warning message, but I dont understand why Im getting it here, since Im dealing with vectors...the code works and everything, but I keep getting that and I don't know how to get rid of it.

Any hints?

Thanks.

You need to use type prefix on the first usage of @-binding inside wrangle: i@ptn will work. Without prefix, it will be defaulted to f@ptn or to the proper type, if the attribute name is something common (standard VEX/VOP variables and globals are recognized).

Oh ok, so I must specify the type of the attribute even if I didnt created that attribute but already exists in houdini?

I wasn't aware of this...thanks

I suppose you want to use @ptnum instead of @ptn for the number of the current point? Then the attribute is buitin and you do not need to prefix it.
And you can simplify the call a bit by replacing

attrib(1, "point", "up", @ptnum) 

by

v@opinput1_up

This only works if you are requesting an attribute for the same point number from any input.

Yea I nedeed @ptnum but I wrote @ptn because thats an attribute I use in another wrangle in the same scene...
