I have implemented 2 Javascript classes in C++, Camera and Point. I
can currently do this:
[code]
var camera = new Camera;
var point = new Point(x, y, z);
camera.position = point;
[/code]
I can get the values of point, inside Camera:position and set the
position of the camera fine.
My issue is that i don't know how to return a Point object when I do:
[code]
var point = camera.position;
[/code]
This is what I current have for setting and getting the
Camera::position variable, which is of type Point.
/**
* Get the position of camera.
*
* <javascript>
* usage: var vector = $camera.position;
* </javascript>
*/
v8::Handle<v8::Value>
jsi_Camera_get_position(v8::Local<v8::String> property, const
v8::AccessorInfo& info)
{
JSCamera* camera = jsi_internal_Camera_unwrap_camera(info.Holder());
// Change the camera.
std::stringstream ss;
ss << "Camera.position (get)";
BBB::log(ss.str());
// How to return a Point?
return v8::True();
}
/**
* Set the position of camera.
*
* <javascript>
* usage: $camera.position = new Point(5.0, 5.0, 10.0);
* </javascript>
*/
void
jsi_Camera_set_position(v8::Local<v8::String> property,
v8::Local<v8::Value> value, const v8::AccessorInfo& info)
{
JSCamera* camera = jsi_internal_Camera_unwrap_camera(info.Holder());
// ------------------------------------- //
// Make sure we have an object.
if (!value->IsObject()) {
std::stringstream ss;
ss << "Camera:position -- Argument must be of type [object
Point].";
BBB::log(ss.str());
return;
}
// Get the C++ class in this javascript object.
v8::Local<v8::Object> pointObj = value->ToObject();
v8::Local<v8::External> external = v8::Local<v8::External>::Cast
(pointObj->GetInternalField(0));
C4::Point3D* point = static_cast<C4::Point3D *>(external->Value());
// ------------------------------------- //
// Set the position of the node.
camera->SetNodePosition(*point);
// Change the camera.
std::stringstream ss;
ss << "Camera:position (set)";
BBB::log(ss.str());
}
