Parameters: array An array containing the elements of the vector in the order x, y, z, w.

void set ( const Vec4 & v )

Sets the elements of this vector to those in the specified vector.

Parameters: v The vector to copy.

var set ( var v )

Sets the elements of this vector to those in the specified vector.

Parameters: v The vector to copy.

local set ( local v )

Sets the elements of this vector to those in the specified vector.

Parameters: v The vector to copy.

void set ( const Vec4 & p1,
