What is the best way to extract float variables from a Javascript
function call.
The javascript would look something like this:
=========
------------------
var point = new Point(2.5, 7.1, 4.8);
------------------
=========
The C++ currently look something like this:
=========
------------------
v8::Handle<v8::Value> jsi_Point_construct(const v8::Arguments& args)
{
v8::HandleScope handleScope;
if (!args.IsConstructCall()) {
return v8::ThrowException(v8::String::New("Point: Cannot call
constructor as function."));
}
if (args.Length() != 3) {
return v8::ThrowException(v8::String::New("Point: Constructor
takes
3 arguments."));
}
float x = static_cast<float>(args[0]->Int32Value());
float y = static_cast<float>(args[1]->Int32Value());
float z = static_cast<float>(args[2]->Int32Value());
Point3D* point = new Point3D(x, y, z);
// make a persistant handle for the instance and
// make it weak so we get a callback on destruction
v8::Persistent<v8::Object> self = v8::Persistent<v8::Object>::New
(args.Holder());
self.MakeWeak(point, jsi_Point_destruct);
self->SetInternalField(0, v8::External::New(point));
return self;
}
------------------
=========
Thanks for any help
