Hey all -
I'm trying to get out of crazy, incomprehensible VOPsop if-then blocks, and get to writing some actual VEX code. I've been working with the new pointWrangler, and am making good progress.
However, I'm trying to define a function and I'm getting errors. I've followed the instructions in the VEX manual, and this is my function:
void populatePoints(float i) {
//null null null
}
However, I get the error:
Syntax error, unexpected identifier, expecting ‘(’
Hopefully this is an easy mistake. Thanks!

Unfortunately you can not define functions inside the Snippet VOP/SOP and even inside the Inline VOP.
You will have to create a new VEX Builder Type. Or you can use a separate file to define your functions and include them. You can also use the #define directive to define simple functions like this:
#define noise0(PP) (2.0*noise(PP)-1.0)
I have been asking for this feature for a long time, and without it, these operators are greatly limited in what you can do with them.

You can't do it using the Wrangle SOPs as the parameter is not promoted. But if you use a Snippet VOP, then there is a parameter that allows you to include files.
The problem with using extra files on disk is portability though. You can save the file inside Extra Files of a digital asset, but you still can't include this file as you should because this functionality is currently broken (Bug ID #54180).
So this forces people to create new operators to run relatively complex VEX code to solve specific problems that doesn't make sense to have as separate operators.
