"*this" will try to dereference the this pointer. You don't want that, if you're accepting pointers into the addObjectToList function
Also, you probably want


class character
{
public:
    character();
}

Also


addObjectToList(character *obj)
{
objectList.push_back(obj);
}

as you don't qualify the items that you are pushing into your list (as the list is a vector of characters anyway).

Nono, post-decrement is exactly what I needed. What had to be changed was:


$i = abs($length / 3); >>> $i = abs(intval($length / 4));

It seems that at some previous point the method was only generating 3 characters per iteration. It was later changed to generate 4 characters but someone forgot to change the number of iterations. Took me a while to get a hold of person who wrote it in the first place and get him to recall how and why did he did it this way...

I've also made it convert division to integer since abs can be float and it could get silly (as in endless loop blowing out the stack) if someone wanted to generate an odd-length password.

whoops I was too excited to apply our new knowledge of post and pre increment decrement operators!

4 is right, 3 is wrong o:

Yeah, but this isn't my priority. Just "boyscouted" it while fixing something else entirely

I still couldn't stand it and now this method looks like that (and returns proper length):


    protected function generatePassword($length = 12)
    {
        $lowercaseLettersArray = range('a', 'z');
        $uppercaseLettersArray = range('A', 'Z');
        $numbersArray = range(0, 9);
        $specialCharactersArray = array('_', '!', '?');
        $randomizedString = '';

        $randomizedString .= $this->getRandomCharacterPairFromArrays($numbersArray, $specialCharactersArray);

        $i = abs(intval(($length - 2) / 2));

        while ($i--) {
            $randomizedString .= $this->getRandomCharacterPairFromArrays($lowercaseLettersArray, $uppercaseLettersArray);
        }

        return str_shuffle($randomizedString);
    }

    protected function getRandomArrayMember($array)
    {
        return $array[array_rand($array)];
    }

    protected function getRandomCharacterPairFromArrays($firstArray, $secondArray)
    {
        $characterPair = '';

        $characterPair .= $this->getRandomArrayMember($firstArray);
        $characterPair .= $this->getRandomArrayMember($secondArray);

        return $characterPair;
    }

He'll get a password one character shorter. Not my problem really, I only made the code easier to understand, a bit more efficient (one loop instead of four), a bit more elegant, a bit more in line with what was originally intended and a bit safer (no more floats in loop conditions). Wasn't my job to create the algorithm or update it.

I recently saw a few posts on gamedev about entity based architecture in c++.

I was wondering how I could make a custom component and then attach it to my entity. I would assume that the base enitity would just be a long int

ref: http://gamedev.stackexchange.com/questions/31473/role-of-systems-in-entity-systems-architecture/31491#31491

I don't think that post actually describes the ideas involved in an entity system at all. It just describes one very specific approach. (What follows is a segue into my own theories, and may not be relevant / helpful, sorry about that). >.>

I think the whole thing comes down to balancing lookup, iteration and sorting.

If you use the heap for entities and (more importantly) components, you automatically get persistent handles (pointers!) that you can use for the lifetime of the object, and no lookup cost. This is really, really nice. It's something you shouldn't give up unless you have a really good reason.

The downside of this is that it might be slow if you want to iterate over a whole bunch of the same component type: you're jumping all over the place in memory. However, this isn't an issue 99.99% of the time. The solution to this problem is to store your objects in contiguous memory (i.e. a vector / array). Your choices then become (from some notes I made a while ago):


// Plain array
	// Fast creation / deletion
	// Fast iteration
	// Can't do lookup and / or sorting without additional hassle.

	// Possible lookup types:

		// Intrusive ID
			// Fast iteration - (slightly slower than plain array)
			// Slow lookup - O(n)
			// Fast sorting.

		// ID + index map
			// Fast lookup - O(log(n)) or O(1) ?
			// Requires custom sorting code.
			// Very slow sorting - updating indices during swap :(

		// ID + index list
			// Fast lookup - O(1)
			// Requires custom sorting code.
			// Very slow sorting - updating indices during swap :(

Of these, the intrusive ID version is probably the best, but still: If speed is really an issue (it isn't), you're almost certainly better off refactoring the offending components into pure data stored in an appropriate aggregate component, rather than changing the component system itself.

So here's a bunch of pseudo-code with what I'd basically do:



class Component
{
public:
	
	virtual void Connect(GameObject& object) = 0;
	virtual void Disconnect() = 0;
	
	virtual std::type_index GetType() const = 0;
};

class FooComponent final : public Component
{
public:
	
	void Connect(GameObject& object)
	{
		// get other components from object if necessary...
		
		// attach to relevant systems:
		Service<FooSystem>::Get().AddComponent(this);
	}
	
	void Disconnect()
	{
		Service<FooSystem>::Get().RemoveComponent(this);
	}
	
	std::type_index GetType() const
	{
		return std::type_index(typeid(FooComponent));
	}
};

class FooSystem
{
public:
	
	void AddComponent(FooComponent* component);
	void RemoveComponent(FooComponent* component);
	
private:
	
	std::vector<FooComponent*> components;
};

class GameObject
{
public:
	
	GameObject():
		connected(false) { }
	
	~GameObject()
	{
		Disconnect();
	}
	
	GameObject(GameObject const& other) = delete;
	GameObject& operator=(GameObject const& other) = delete;
	
	// You can add a move constructor / move assignment if you wish.
	// Just don't store pointers to GameObjects if you do.
	
	
	template<class T, class... Args>
	T* AddComponent(Args&&... args)
	{
		// create component
		// add to vector
		
		// if object is connected
			connect this component
		
		// return component
	}
	
	template<class T>
	bool HasComponent() const
	{
		for (auto const& c : components)
			if (c->GetType() == std::type_index(typeid(T)))
				return true;
		
		return false;
	}
	
	template<class T>
	T* GetFirstComponent();
	
	template<class T>
	std::vector<T*> GetAllComponents();
	
	template<class T>
	void RemoveFirstComponent();
	
	template<class T>
	void RemoveAllComponents();
	
	void ClearComponents();
	
	
	void Connect()
	{
		if (connected)
			return;
		
		for (auto& c : components)
			c->Connect(*this);
		
		connected = true;
	}
	
	void Disconnect()
	{
		if (!connected)
			return;
		
		for (auto& c : components)
			c->Disconnect();
		
		connected = false;
	}
	
private:
	
	bool connected;
	std::vector<std::unique_ptr<Component>> components;
};

// So then:

auto player = GameObject();

player.AddComponent<PlayerController>();
player.AddComponent<ShipRenderable>();

auto collider = SphereCollider(10.f, 1.f);
auto physics = player.AddComponent<PhysicsComponent>(collider);
physics->SetRestitution(0.5f);
physics->SetLinearVelocity(Vector3(0.f, 0.f, -1.f));

player.Connect();

// And everything will be neatly removed / destroyed when the player object goes out of scope!
// You can store the object itself in a unique_ptr, or whatever you need!

The type_index stuff is kind of a pain. You could restrict your objects to only one component of each type, but I don't think it's really necessary. You could perhaps also store components in a map or multi map, and remove the need for the GetType function.

The main thing I see wrong with the post you linked at the start is that at some point you're going to want to write actual gameplay logic. For example... "an object has collided with this one -> check if it's the player, if so play an explosion sound, damage the player, apply a force to push them away". This requires access to a whole bunch of components or systems. That article says that components are basically just data, and can't interact at all, implying that you'll have to create a new system for almost everything.

The components are also so fine grained (separate position and velocity!!) that I suspect you'll quickly become mired in a mess of combination problems and inter-dependencies masked by putting everything in yet another system.

But anyway... to answer your question:

I have no idea! I thought about it for a bit. I imagine you'd want an enum with all your bitmasks e.g.:


enum ComponentTypes
{
    PhysicsComponent = 1u << 0u,
    PlayerComponent = 1u << 1u,
    ShipComponent = 1u << 2u,
    // etc.
};

The entity could then contain a long unsigned , and you could do something like "entityMask |= PhysicsComponent;" when you add a component.

But that's going to be a pain in the arse to maintain. You're also probably going to want each component type to have a GetType() function (similar to my own example) that returns the relevant mask type. This is already more irritating to maintain than my example above. You could try some weird automatic type registration, but that's waaay more complicated.

Then you have the problem of where you store components. You'll end up doing basically what I did above, anyway. I don't see what you gain from systems looking for relevant components, apart from more complication.

TLDR; Go back to that article, and tell the author to show some code or GTFO (but perhaps more politely).

I've been doing some nooby c-programming and I can't quite wrap my head around this piece of code. Or rather I thought I could but the result doesn't really match my expectations.

I have a linked list based stack that I push and pop a bunch of numbers to, but the requirements then asks that they are printed out in the order they are added. So I googled for a function to reverse it found this here.

void stack_reverse(struct node **top, struct node **top_next)
{
  if(*top == NULL)
  { 
    return;
  }
  if(*top_next  != NULL)
  {
    temp = (*top_next)->ptr;
    (*top_next)->ptr = (*top);
    *top = *top_next;
    *top_next = temp;
    stack_reverse(top,top_next);
  }
}

No here's what I would think happens (excuse my paint):
+ Show Spoiler [before] +

+ Show Spoiler [What I would think would happen] +

2,3,4 ptrs are swapped and top points to 4.

+ Show Spoiler [what actually happens] +

So basicly (*top_next)->ptr = (*top); makes the pointer point "in the other direction" (if that makes sense), but I can't see how the previous top (that becomes the bottom) is set to null. But when I run my code, that's what seem to happen.

So basicly it IS working but I thought it shouldn't. For instance this loop where I print the stack out terminates, so at some point it does reach a null pointer:


    while (top1 != NULL)
    {
      write_int(top1->info);
      top1 = top1->ptr;
      if (top1 != NULL)
      {  
        write_char(','); 
      }
    }

Can someone explain how the '1'node->ptr gets set to null?

The last node in the list has a pointer to null. This null is saved in the temp variable passed through the entire list until the end where the function returns so the recursion ends.

If the function ended up like "what you think" then you wouldn't be able to tell when the list ends and you'd have an infinite loop.

Tips for C data structures and methods..

Don't re-use temporary variables
Zero out pointers everytime a variable is initialized
Name things well
Reuse small pieces of code that are 100% guaranteed to work
Avoid recursion if possible
If your code isn't easily readable it'll probably have a bug
If your algorithm is complex and not concise it'll probably have a bug

If you want to print the stack "in order" without modifying the data you might as well do something like this:


bool print( struct node *element )
{
    if ( element == NULL )
        return false;

    if ( print( element->ptr ) )
        write_char( ',' );

    write_int( element->info );
    return true;
}

These are excellent tips for pretty much any language.

Of course not every language has pointers, and extensive recursion use is fine in some languages, but the other points stand for every programming environment I can think of.

I find those ideas are especially important when playing around with fundamental structures in C/C++ specifically. In lots of languages and problems, you can kind of get away with poor syntax or poor algorithm construction. But when we're talking about implementing a stack in C, or deleting a node from a binary tree, and other basic fundamentals, those are the small, super important lessons I've learned from coding and failing a lot :3 just because C forces you to be so much more explicit that if you're too lax or even overly specific you'll cause an insignificant number of problems (not helped by the compiler...) meanwhile other languages have enough abstractions to cover your ass :p

hey boys, maybe you could give me a pointer here.... the tough part isnt really "finding out what to do" after all.....if you look at enough examples you get the general picture eventually.... but the tough part is finding out how to do it coz it seems like no one does stuff "exactly" how i want to do it and guessing how to do stuff is pretty stupid lol.....you can spend 5 hours trying to guess something and then just ragequit it and have wasted the whole day for no reason whatsoeever.

anyway , again i am trying to receive a response from a 3rd party API, put the response into an object , then print the object to screen so i can verify it (actually you can verify using breakline i bet but again thats fucking around for ages hoping something works and not getting anywhere)

so this is what i have so far, and i have 1 (maybe) missing line that might make it work ......fingers crossed...

Ann.java class that stores the xml data received from the 3rd party api. this was generated by using JAXB wizard on XSD scheme of a sample XML (2500 lines long ...i just paste some of it coz it wont let me paste 2500 lines lol)

ObjectFactory.java , this was generated alongside the Ann class ... not sure what it does, maybe i need to use it or maybe it was used by the system in generating the Ann and i dont need it anymore..... or maybe its used automatically in processing XML data to put it into the Ann class, in which case i DO need to use it somewhere (unless its used super-automatically)

getservice.java, this gets the xml file from animenewsnetwork , it works in that you can print the response to a string but i dont know if it successfully parses the response into the Ann class like i have it right now. i think i should run it with a breakpoint and see if anything comes up there...... the thing is, i cant just "run" that file coz it says there's no Main file, so i went next to make a main file
