Graphics / Re: Sprite as attribute doesnt Draw but local sprite Draw

« on: September 16, 2012, 06:44:57 pm »

Humm...ok.

I think that texture is store in the sprite and the object is not destroyed.

And don't dynmically allocate the exceptions that you throw.

I dont understand it ^

Hi,

o.o

The problem is here:

window.clear(sf::Color(255, 255, 255));
        window.draw(*robot1->getSprite());  // it dont display
        window.draw(*sprite);   // it display
        window.display();

I think it is not related, because the sprite in another class out of v8.

https://github.com/prsolucoes/sfml-cmake/blob/master/main.cpp
and
https://github.com/prsolucoes/sfml-cmake/blob/master/Character.cpp

Look only this two files, is a short piece of code.

I need implement that methods for cast on every class that i send to v8? Example:

namespace v8wrap {
    v8::Handle<v8::Value> CastToJS(const Character &JS);
    v8::Handle<v8::Value> CastToJS2(const Character &JS);
    void AutoCastToCPP(v8::Handle<v8::Value> Value, Character &CPP);
    v8::Handle<v8::Value> CastToJS(Character *JS);
    v8::Handle<v8::Value> CastToJS2(const Character *JS);
    void AutoCastToCPP(v8::Handle<v8::Value> Value, Character *&CPP);
}

Graphics / Sprite as attribute doesnt Draw but local sprite Draw

« on: September 14, 2012, 10:50:25 pm »

Hi,

Im with a small problem here that my sprite that is in my class "Character" doesnt "draw" with "window.draw", but if i create a local sprite (the same sprite code and image) it draw.

You can see here (have both sprite - local and as attribute):
https://github.com/prsolucoes/sfml-cmake

I got no error and when debug, all sprite attributes is fine

PROBEM SOLVED!!!! URRRULLLLLL!!!!

GDB IS THE BEST!!!!!

I need initialize the null attribute "POT":

JSCharacter::InitPOT(JSCharacter::POT);

One thing i discover, that the errori got here:

v8::Handle<v8::Object> Result = Character::POT->NewInstance();

I have commited a working version with custom class commented and working with a simple sprite, while i discover how exchange c++ classes to v8.

UPDATED:

More specific here:

Character::POT->NewInstance();

UPDATED - ANOTHER CLUE:

Now i know where is the problem, but dont know how to solve it

It is acessing a NULL value but, why?

If we "print" the property "val_", we have a NULL object:

(gdb) print val_
$1 = ('v8::ObjectTemplate' *) 0x0

I like debug - step by step

I like know whats happen and have full control.

I will search for it, but if you have a light, i will be grateful

I think that it is simple and i forgot something, because i copy a sample class in "sf_v8".

Thanks.

General / SFML and V8 - Send custom classes and objects to V8 vm

« on: September 14, 2012, 05:14:02 pm »

Hi,

I made a project that use V8 integration with SFML, but my problem is with custom class/objects that i want that V8 can see.

I created a class "Character" like the same of others "sf_v8" classes. But my application open and close,and the default error "Segment fault".

I can use my project with sf::Sprite class, it is working perfect. But now i want custom classes.

Can anyone help me?

You can see where i stop here:

Thanks.

I see one difference in compiler name, but i dont know if is it. In the cmake project file i forced both to use "g++".

Can anyone help me?

I made a poor implementation of copy required files and the project is working now.

If anyone want help make it better and more "cmake" style, please contact me or send message here with suggestions.
