Object oriented scripting, ican do it :D

Hi all !

I' m working on the EGO Script Engine.

I just finish the hardest thing i guess... the objects!

Code:

class CProp
{
	char* name;
	char* value;
public:
	CProp(char*);
	~CProp();
	char* GetName() {return name;}
	void SetProp(char* valu){value = valu;}
	char* GetProp(){return value;}
};

CProp::CProp(char* input)
{
	name = input;
}
CProp::~CProp()
{
	name = "";
	value = "";
}

class CObject
{
	char* name;
	std::vector<CProp> props;
	std::vector<CProp>::iterator props_it;
public:
	CObject(char*);
	~CObject();
	bool CreateProp(char* name, char* defaultval)
	{
		for ( props_it = props.begin(); props_it != props.end(); props_it++ )
		{
			if (props_it->GetName() == name)
			{
				std::cout << "Error: 0003 , Props: " << name << " is already defined.\n";
				return false;
			}
		}
		props.push_back(name);
		for ( props_it = props.begin(); props_it != props.end(); props_it++ )
		{
			if (props_it->GetName() == name)
			{
				props_it->SetProp(defaultval);
				return true;
			}
		}
		return false;
	}
	bool DeleteProp(char* name)
	{
		for ( props_it = props.begin(); props_it != props.end(); props_it++ )
		{
			if (props_it->GetName() == name)
			{
				props.erase(props_it);
				return true;
			}
		}
		std::cout << "Error: 0002 , Object: " << name << " can' t be deleted because it isn' t exist or can' t found his index.\n";
		return false;
	}
	char* GetName() {return name;}
	std::vector<CProp> GetPropList() {return props;}
};

CObject::CObject(char* input)
{
	name = input;
}
CObject::~CObject()
{
	name = "";
	props.clear();
}

class CObjectManager
{
	std::vector<CObject> objects;
	std::vector<CObject>::iterator objects_it;
public:
	bool CreateObject(char* name)
	{
		for ( objects_it = objects.begin(); objects_it != objects.end(); objects_it++ )
		{
			if (objects_it->GetName() == name)
			{
				std::cout << "Error: 0001 , Object: " << name << " is already defined.\n";
				return false;
			}
		}
		objects.push_back(name);
		return true;
	}
	bool DeleteObject(char* name)
	{
		for ( objects_it = objects.begin(); objects_it != objects.end(); objects_it++ )
		{
			if (objects_it->GetName() == name)
			{
				objects.erase(objects_it);
				return true;
			}
		}
		std::cout << "Error: 0002 , Object: " << name << " can' t be deleted because it isn' t exist or can' t found his index.\n";
		return false;
	}
	std::vector<CObject> GetObjectsList() { return objects; }

	// Helpers

	std::vector<CProp> GetPropsByObj(char* name)
	{
		for ( objects_it = objects.begin(); objects_it != objects.end(); objects_it++ )
		{
			if (objects_it->GetName() == name)
			{
				return objects_it->GetPropList();
			}
		}
	}

	char GetPropByObj(char* objname, char* propname)
	{
		for ( objects_it = objects.begin(); objects_it != objects.end(); objects_it++ )
		{
			if (objects_it->GetName() == objname)
			{
				std::vector<CProp> props = objects_it->GetPropList();
				std::vector<CProp>::iterator props_it;
				for ( props_it = props.begin(); props_it != props.end(); props_it++ )
				{
					if (props_it->GetName() == propname)
					{
						return *props_it->GetProp();
					}
				}
			}
		}
	}

	bool CreatePropByObj( char* objname, char* propname, char* defvalue)
	{
		for ( objects_it = objects.begin(); objects_it != objects.end(); objects_it++ )
		{
			if (objects_it->GetName() == objname)
			{
				return objects_it->CreateProp(propname, defvalue);
			}
		}
	}

	bool DeletePropByObj( char* objname, char* propname)
	{
		for ( objects_it = objects.begin(); objects_it != objects.end(); objects_it++ )
		{
			if (objects_it->GetName() == objname)
			{
				return objects_it->DeleteProp(propname);
			}
		}
	}

} o_Manager;

This is the tests :

Code:

	o_Manager.CreateObject("Object1");
	o_Manager.CreateObject("Object2");
	o_Manager.CreateObject("Object1");
	o_Manager.CreateObject("Object3");
	o_Manager.CreateObject("Object2");
	o_Manager.CreateObject("Object4");
	o_Manager.CreateObject("Object5");
	o_Manager.CreateObject("Object6");
	o_Manager.DeleteObject("Object5");

	o_Manager.CreatePropByObj( "Object1" , "Props1", "Value1");
	o_Manager.CreatePropByObj( "Object1" , "Props2", "Value2");
	o_Manager.CreatePropByObj( "Object1" , "Props3", "Value3");
	o_Manager.CreatePropByObj( "Object1" , "Props1", "Value1");
	o_Manager.CreatePropByObj( "Object1" , "Props4", "Value4");
	o_Manager.CreatePropByObj( "Object1" , "Props5", "Value5");

	o_Manager.DeletePropByObj( "Object1" , "Props4");

with a little code to display the objects it show :

Quote:

Error: 0001 , Object: Object1 is already defined.
Error: 0001 , Object: Object2 is already defined.
Error: 0003 , Props: Props1 is already defined.
Object1
{
Props1 : Value1
Props2 : Value2
Props3 : Value3
Props5 : Value5
}
Object2
{
}
Object3
{
}
Object4
{
}
Object6
{
}

Dont know why i was browsing the off-topic forum. Jobless I guess.
Cr3v3t3, why dont you post this in the 'HL2 / SM coding' forum?

Cr3V3TT3 · 05-14-2005 , 18:20

Because its not for hl2 or sm.

I wana do a script engine for "Messenger Plus!"
I made some tests with SpiderMonkey( JavaScript ) but i dont got enough skill to do it

So i decided to do mine :]

Project EGO is a temporary name ^^
It's just a simple open source scripting engine
