Sorry for being late ;). I missed the start.
It is the second competition I am participating. The planned game is not only for this competition. I worked before on it and it is too big to finish it this competition. For the graphics (my problem in the last competition) I have a friend, who wants to/has to make the images.

The game shall be structured like this:

• Storry: not really existing… Maybe >Explore the Planet "Leto"<
• "Public and open"(*) levels.
• Every player has a profile and a figure (dunno wheather its the right word). He also has an inventory with different arms.
• he can "kill"(I'm still trying to find a good kill system) monsters and players.
• He has to come through the levels (like jump'n'run).
• Log-In, shop, friends, in-game chat, achievements, improvement of the player with XP-levels
• Different regions (like ice-world, dessert, swamp, …)

(*) Log-In required

Special goals and callenges:

• Organize a huge amount of data (the profiles, levels, etc.)
• Find an efficient and fast way of syncronization of the public levels between the server and the clients.
• Make a fast collision-detecting-and-moving method for the Player class
• Languages: German & English (maybe Latin for fun :D)
• Smooth moving of the objects using forces and acceleration.

At the moment, I have a working Log-In and a rough menu. For the comming week, I will work on the classes and interfaces I need for the levels(IStaticObject, Player, Platform, …)

Definitely never too late to jump in!

Seems like an interesting game, but I think you're right. It's going to take more than a single 30-day competition to complete it. But that's OK! That's how it's supposed to work.

I'm curious about what tools/engine are you using. Any insight?

I am simply using MonoGame with libaries I have written or I am currently writing for physics, graphical objects (like buttons, textboxes, listboxes, progress bars, etc…) and other stuff.

I achieved my goal for this week (getting a basic level structure with a moving player).
I have a player (the smiley named test123 ;) ) now who can move on platforms (the ones with the white center), obstacles (the black ones), and force fields (the grey one(s)). The platforms block from the top, the obstacles from all sides and the force fields accelerate the player in a specified direction.
—> Look at the gif posted by PiscesMike. I am not allowed to post images. (Achievement: It's Just Temporary: You put in artwork in your game that you claim is temporary, until you or your friend can provide you with better art.)

This is just local. Next week I will work on the levels and the menu, including the client-server connection. Maybe I will start with the level editor, too.

ToDo for the levels:

• Think (and try to program sth.) about the level organization (e.g. entry and leaving point), zoom, and a moving viewport for a moving player
• Write commands for the moving players.
• Add the level update logic on the server
• Add a simple attack

ToDo for the menu:

• Adding buttons or similar things to enter a level
• Make friend organization with a list box and automatic profile loading

ToDo for the editor:

• Create a syntax for documents that save the levels, including load and save methods.
• Make a project for the editor and start working on it

Maybe I cannot complete all this Tasks this week, but I will try. We are writing no test in school anymore before the hollidays so I have time ;).

By the way, really cool! The force field is an interesting effect.

Good job!

Tristan,

That looks like a great start for one week of work. Looking forward to seeing how the multiplayer aspect comes together.

Question about the internet

TristanSt 07 Jun 2017 20:22

I have a problem with the mentioned connection of the server and the client.
I am using a TCP connection with commands for the 2 "parts". Both are running on 50 fps.
The Client has a separated thread for the connection. It communicates with the main thread with 2 static List<string>: "CommandsToSend" and "CommandsToRead".
The Server has one thread for each level.
The player's update method works with a vector representing the resulting force(F_net) on the player. With commands like "right" the server adds a number to F_net.
It "works". I have a player which I can move. But it is very irregular and after I pressed a key, I have to wait something like a half second until the player moves. It works like this:

Server	Client
frame x	frame x ("jump" is pressed and sent)
…	…
frame y ("jump" is recieved, calculated, and "jumped" sent)	frame y
…	…
frame z	frame z ("jumped" is recieved and the player jumps)

Has anybody an idea how to fix this syncronization problem?

Re: Question about the internet

Without looking at the actual code, it's going to be hard to figure out exactly what's going on.

That being said, I'd check to make sure the message delivery is not set to guaranteed delivery. Not even sure where to tell you to look for that at the moment, but it should be somewhere in the TCP setup.

With guaranteed delivery, network propagation times go up significantly, since it has to double check for errors, dropped packets, etc, etc, etc. It at least doubles the threads reaction time.

Hope that is of some help!

I got it!
The client-server connection of the levels has nearly no delay now. I changed the Internet Protocol from TCP to UDP for this part of the game. And everything is now a lot more efficient because of multicasting.

I completed my goals of the Levels, the first one of my menu goals and some parts of the editor goals.
=> The game is now online "playable" (in test mode(!)).

My next goals for the last few days are:

• Creating a functioning (not beautiful!) level editor, I think I integrate it in the main Program
• Testing the multiplayer function
• Creating a server controller program to change the server setting during runtime (like adding or removing player accounts)
• Add more menu items (like friend organization (see my last update) or the shop)
