Whats the different between these two?
();
{};
curly braces.


Ive just started following the CGwiki guide to houdini and was learning the sop solver.I came across this snippet of code .


–Faked Physics–

@v = {2,2,0};
v@gravity = {0,-0.1,0};


–
but i accidentally used () and got a result the sphere translate -y.I checked the help file to see what the User-defined functions provide but i saw none for the curly braces.

In VEX, there are two ways to explicitly assign values to a vector variable:

1. If the values include variables, write

   @v = set(x,y,z);
   

2. If the values are constants, write

   @v = {2,2,0};
   

So, {2,2,0} gives you a vector. is the same as .

(2,2,0) on itself is not meaningful. I believe it returns the last value in the bracket.
