В своем классе для точек вы можете использовать что-то вроде

Однако вам действительно следует переосмыслить / реструктурировать свой код и подумать, кто за что будет нести ответственность.

Лично я не хотел бы, чтобы точки отвечали за увеличение очков и завершение игры. Я бы предпочел иметь компонент на самом игроке, пусть он проверяет столкновение, увеличивает свои собственные очки и, в конце концов, говорит какому-нибудь менеджеру завершить игру, как только так как все точки были уничтожены;)

Если вы спрашиваете: «Как мне сообщить игре, что уровень закончился и вызвать конец?», Тогда просто имейте переменную для хранения количества точек на уровне, и каждый раз, когда вы едите одну, запускается коллайдер. , есть счетчик. Когда счетчик равен сумме, уровень заканчивается.

Я думаю, вы могли бы использовать что-то подобное. Просто сохраните все пакеты в массиве, и как только массив станет пустым, вы сможете завершить игру.

Pacman

The player and ghosts don’t need any functional game logic behind them right now. Just make sure they are rendering and moving about before continuing on.

Engine Abstraction

This lab is where our game code starts to look more like a game engine. This is inevitable once a game reaches a certain level of complexity. Pacman just tips over that threshold where we can justify using some major-league game software architecture.

Entity Management

Games will have thousands of Entity’s in flight, keeping them all in one global vector is not a good idea. Having multiple lists — relevant to their use is a better idea. This is a topic that strays instantly into optimizations, which really depend on the game you are making.

What we are going to go for in this lab is collating all the entities by the scene/level they are in. for pacman, we will just have two scenes: Game and Menu .

To move pacman to this paradigm is not going to take much of a change in code. Here’s it is:

The implementation of the two functions do exactly what you would expect, loop through the vector and update/render all Entities. Replace your Global entity vector in main.cpp with an EntityManager called ‘em’, and insert both the player and ghosts into via em.list.push_back() . Swap out the calls to Update and Render to the pass through the manager instead.

You may be wondering why we even bothered doing this. We took simple code and made it more complex.

The point is to move Entity management logic to a more appropriate place. This allows us to split our code into that we can expand upon and re-use later. This is the first small step on a big journey.

Render system

An annoying feature of our code right now is how we render Entities. Passing a reference around to the windows seems a little wrong seeing as the variable never changes. Let’s fix this and pave the way for a new cool system.

The Renderer

In most game engines, the system that handles rendering things is usually the largest and arguably the most important. For us, we only need to pass what we want to draw to SFML and it handles it all. You can bet the internals window.draw() function is pretty damn impressive (it is, go and look). We don’t need a complex rendering system on-top of, but we’ll build something anyway, if only to point out how a more complex system would do things. If we weren’t using SFML this is where things would get real complicated quickfast.

Our Render system will have a simplified Render() function that will take in a sf::Drawable object (e.g sprite,shape,text), and add this to a list of things to render.

The big difference here is that things won’t be rendered immediately. The list will be built up of objects as each Render() function is called on all the Entities.

Once this process completed, we sent it all to SFML all at once.

The benefits to this is that we can keep track of how many things we are rendering per frame easily. More importantly it allows us to do optimisations. If z-order were important we could re-order the list to draw background objects first. Or do some form of debug-culling to stop certain object types of rendering. All useful stuff.

Again, if we were working with OpenGL or a more complex render system, this is were we would do some serious work. The reality is that SFML does almost everything for us so we don’ actually have much to do here.

All that’s left to do is Initialise the system from main.cpp, and call Renderer::render(); a the end of the main render() call.

Now whenever we need to render anything we can call something like.

You might need to use .get() on the unique_ptr in your player or ghost.cpp if you are following along correctly!

Scene Management

As mentioned above, we will have two ‘scenes’. What is a Scene? Mainly it’s a collection of Entities. All of the game logic will mainly be inside the Entities, but there will be some global game logic that needs to run, and the scene class is where it shall be.

The scene should also be responsible for loading and unloading content that it needs. This is where we could implement a loading screen. This would run while a scene loads, and then display the scene once finished. We shouldn’t be working with anything that will need a loading screen, simply freezing for a few frames while we transition scenes is acceptable (for now … hint hint).

Here we have our scene class. It has our usual two Update and Render functions, and an internal EntityManager. Additionally we have a Load() function and a public getter to the entity list.

hint: Here’s the base Scene render(). You should be able to define the other functions yourself.

We should instantiate our two scenes. We should do this away from main.cpp – in a separate header that contains only Pacman related things: pacman.h . As these are extern’d, define them in pacman.cpp .

The Menu scene

We’ve declared the two scenes we need as pointers to the base Scene class, when it comes to implementation, they will actually be two different classes. We should declare them in pacman.h and define them in pacman.cpp.

We will bring along any gameplay variables that would normally be in the global scope of main.cpp, and have them as private properties in each scene. For the Menu, this is just a single sf::Text.

Remember! For the text to show you will have to load and assign a font! Remember Pong?

The Game scene

For the main game-play scene, we will have an extra method: Respawn() and a scoreClock. This is all we need for global game logic in the scene, the entities handle everything else.

The ghosts and player that are still stored in a global EntityManager should now be moved into the GameScene. Each scene has it’s own EntityManager, stored privately as _ents . Do the Entity creation in the Load() function. I.e:

Instantiating the scenes

All that’s left to do is actually Instantiate the two scenes, we do this in the main Load function. We can really start to see how we are separating out the logic to the different systems, with main.cpp becoming a small part that glues it all together.

Changing scenes

Switching between the scenes is done with the variable ‘activeScene’.

Checkpoint

After this long round trip, implementing a new render system, An entity manager class, a Scene class, and creating two scenes, we should be back to where we begun. The game will start to the menu scene, where you should see the text “Almost Pacman” Drawn. Pressing Space will take you into the game scene, where our player and 4 ghosts will be on screen and moving around. Pressing Tab will take us back to the menu. Pressing Escape will close the game down.

Make sure you have got here, and everything is working so far without any errors. Things are going to get a bit wild next. You should commit your code now. READ THE NEXT SECTION, IT’LL HELP I PROMISE

Sanity Check

Okay… but do you get what is going on right now? Because I bet a few of you are utterly confused. So, let’s summarise this process a little, and have a brief chat about why it’s important. Second thing first: why is it important?

Put simply, we can now create and manage scenes incredibly easily. If you’ve every made anything in a games engine you’ll know how important scenes are, almost every single game is broken up into distinct scenes which have their own entities, sounds, textures, models etc. Often this’ll be a menu scene and one scene per level, but it depends on how the game is made. But, in the end, they all have the same basic loop: load things, loop through updating and rendering until some end point, unload the things we loaded. Sound familiar? What did we define in our scene.cpp file? load(), update(), render()… but don’t forget we have a constructor and deconstuctor too where we can unload things.

What’s nice about the way we’ve done it, however, is that the main gameplay loop doesn’t have to care about what scene is currently running — it just calls the right functions at the right time on whatever scene is currently active. What is double nice, is that to change which scene is running (i.e. to change from the menu to the game, or between levels) we just swap out which scene is currently ‘active’… and that’s really it. Everything else just works because of clever use of inheritance, polymorphism, and all those other nice OO things.

So, what is the structure of our code now for actually calling update() and render()? Sure, we know how we call update() on the right scene, but how does that propagate to all our entities?

All our scenes inherit from our parent scene class, which contains an EntityManager struct called _ents
Each _ents contains a list that stores Entity objects within it, and has it’s own internal update() and render() functions
These functions both foreach through that list and call the update() and render() functions on each individual Entity (which must inherit from Entity)
The update() functions do our gameplay work on each Entity, the render() functions add each Entity to the Renderer queue
Our main.cpp file uses the shared pointer to our active scene and calls update() on it which causes all Entities to be updated as per above
Our main.cpp file then calls the Renderer render() function, which goes through everything queued up and renders them all!
When we change scene, we just update the active scene, and then a different EntityManager with different _ents is called… which means different update() functions are called, and different Entities are put on the Renderer queue.

Phew… yeah, it’s a bit complicated, and it seems like a lot of work for now, but this will make creating more complicated games later way easier as we’ve decoupled lots of stuff like sensible developers!
