Java

Compatible con Eclipse, Netbeans y IntelliJ

ECS (entity-component-system)

To understand ECS, I recommend to read this. Using artemis framework has been really useful to start rewriting this game.

Kryonet

Avoid creating huge game protocol since we can use Requests and Responses, which can be processed easily with 'visitor' design pattern. Read more here

LibGDX

It allows us to create application game logic, create screens and render all that we need using OpenGL.

Create Resources Entities

Interactable resources like Trees or Ore veins, with the possibility to expand to other types of future resources (like cloth, potion ingredients, etc.)

Create NPCs

libGDX forces System.exit() with non-zero exit value

When the main window is closed, the main loop is stopped, the Application terminated and a system exit is forced with non-zero exit value (interpreted as a failure and throwing an error).

This kills any running threads and right now is fine as it is but eventually the shutdown mechanism should be cleaned.

LwjglApplication.java:

void mainLoop () {
	// ...
	// while() {}
	// ...
	if (graphics.config.forceExit) System.exit(-1); // Throws an error on console
}

Related to #8 .

Energía

La energía no se actualiza:
Al atacar

Implement attack, usage and other intervals

Create server list in login page

We need to create a server list in the login page allowing connect to multiple servers.

Centrado de personaje

El personaje dentro del render se encuentra corrido a la derecha.

Concept of character attributes

Create map

We may use the same mechanism or just TiledMap

Buff GUI indicator

When you are under the effect of a Buff, a graphical representation of that buff need to be rendered on screen.

it may be an icon, when the buff has X seconds left this icon can blink, in like a fade in/out fashion until it times out and disappears.

implement map editor

https://github.com/libgdx/libgdx/wiki/Tile-maps
Comment of @cpbeto in discord talking about tiles

No me acuerdo bien todo, pero algo que le faltaba es el concepto de "objetos".
Osea en un mapa no podías guardar información de objetos tirados en el piso, objetos "fijos" o NPCs
QUIZÁ, se puede forkear el repo de Tiled e implementarle lo que necesitemos
Por todo lo demás Tiled estaba genial
Servía para indexar gráficos de mapa me parece, no objetos o equipamiento.

Lista de servidores

Al perder conexión por caida del servidor, no muestra la lista de servidores cuando vuelve el servidor

About this project

how is the actual state of this project? could be launch a proper server/client with this? what features it has?

Join maps as one world (without map limits)

Client: should handle map transition (prediction) as simple movement and render it correctly
Server: should not distinguish between maps, near entities would be in different maps. NPCs should not be able to pass through map limits and should come back to original position if no enemy target is present

MIDIs cant be faded at the moment

Implement log out

#95

Use cache instead of java maps in AnimationHandler

Avoid keeping all bundled animations in memory. Guava cache should be fine.

Load doors from maps

implement command /telep

Fade-out> Fade-in screen after dying

Effect to differentiate that the user has died. The screen turns black and after 2 seconds it becomes normal.
The effect should be as simple as possible

Debug info with TAB key

De manera similar al F3 en Minecraft, al apretar una tecla se podría mostrar una pantalla de debug, por encima del render y con transparencia.

Se puede mostrar información como fps, tiempo de render, consola de debug, etc.

Review Graphic class and how we store them

Add Bow and Arrows in combat system

Go to Login Screen when the connection is lost.

Popup should notify user what happened

Dinasty ao

hi, whats the actual state of this project?

Load objects from maps

Server sends all entity components but some can be filtered

Filter client irrelevant components when sending entities through network

[Question] Client entities on connect

@guidota Great example of libgdx, artemis, and kryonet!

I've been going through the code a couple days now as there are many patterns and approaches here I'm learning a great deal from. I understand how messages are processed between client/server using the visitor pattern (thanks I'm now using that too). I see how entities are modified and removed with EntityUpdate and RemoveEntity notifications but I'm having trouble finding where the client gets their initial set of entities in the world on connection to the server.
Can you point me in the right direction?
Thanks

Create spells or magic attacks

May be add 'stun' capability instead of immobility, paralysis... Also consider making items with magic attacks

Door Keys, lockpicking

Door can have locks, and other entities too (chests?), they need keys to be opened.
these locks can be picked up based on skill (and minigame maybe?) some others cant be lockpicked.

Depends on #51

Spell casting

Load NPCs from maps

Add Agility and Strength buff

• Update AGI and STR components to have a base value and a modified one.
• Make a handler to keep track the time since the buff were applied.
• Make a system to check and remove expired buffs.

Implement in-game command parser.

Path finding always choose first target instead of nearest

Implement critic attack

Implement Ghost or die system

Add configurable global volume for sounds and music

Create Door entities

doors should have HP and size.
