Creating scriptable object

by Paul Griffiths · in Torque Game Engine · 07/08/2006 (8:18 am) · 8 replies

Hi i wish to create a scriptable object for my webcam project.
pgmedia.awardspace.com/Site/TMessenger/screenshot.php

Ive created a base template:

Header:
#ifndef _VIDEOCAPTURE_H_
#define _VIDEOCAPTURE_H_

#ifndef _PLATFORMTHREAD_H_
#include "platform/platformThread.h"
#endif

#ifndef _PLAYER_H_
#include "game/player.h"
#endif

#ifndef _SIMBASE_H_
#include "console/simBase.h"
#endif


class VideoCapture : public SimObject
{
private:
	typedef SimObject Parent;

protected:
public:
   DECLARE_CONOBJECT(VideoCapture);

   VideoCapture();
   ~VideoCapture();

   static void initPersistFields();
   void inspectPostApply();
   void getDevices();
   bool onWake();
   void onSleep();  
};

#endif


source:
#include "VideoCapture.h"
#include "console/consoleTypes.h"
#include "dgl/dgl.h"

//----------------------------------------------------------------------------

//----------------------------------------------------------------------------
IMPLEMENT_CONOBJECT(VideoCapture);

VideoCapture::VideoCapture()
{
}

//----------------------------------------------------------------------------
VideoCapture::~VideoCapture()
{
}

void VideoCapture::initPersistFields()
{
	Parent::initPersistFields();
}


ConsoleMethod( VideoCapture, getDevices, void, 0, 0, "Get Capture Device List.")
{
	object->getDevices();
}


void VideoCapture::getDevices()
{
	Con::printf("Looking for capture devices...");
}

//----------------------------------------------------------------------------
bool VideoCapture::onWake()
{
	return true;
}

//----------------------------------------------------------------------------
void VideoCapture::onSleep()
{
}


//----------------------------------------------------------------------------
void VideoCapture::inspectPostApply()
{
}


in script i have:

Vidcap = new VideoCapture();


All i receive is syntax error in script, any ideas what i'm missing?
I do not wish to render anything, it's not a GUI or renderable object. Thanks.

ConsoleMethod( VideoCapture, getDevices, void, 0, 0, "Get Capture Device List.")

This line concerns me. Even though it's a void, it still need 2 arguments.

I'm not 100% familiar with how it works, but i know it needs 2,2 for the arguments.

ConsoleMethod( ShapeBase, isHidden, bool, 2, 2, "")
{
   return object->isHidden();
}

See how that code works?

Thanks Ramen but still getting syntax error in script.
I have similar code working for my GUI but i don't wish to render anything.

Uh...wouldn't the script need to be something like:

%Vidcap = new VideoCapture();


You need the % or $ in front of the receiving variable.

Can anyone suggest where i should create my videoCapture object?
All it is to do is find all video cameras and i will have a tab for it in the options dialog alongside audio, video ect.
Where should it be initialised? It should only be initialised once.

I initialised it in main.cs in start function, works ok.

I have:

ConsoleMethod( VideoCapture, getNumDevices, int, 3, 3, "Get total number capture devices.")
{
	object->getNumDevices();
}



int VideoCapture::getNumDevices()
{
	return numDevices;
}

Not compiling, anyone know why?

Got my answer, should be S32's not int's.
