Play.CivMC.net

Version: Java 1.20.1

CivMC is a geopolitical Minecraft server focused on civilization-building. Players form nations and establish governments, wars occur, and treaties are signed. You can play with friends, punish your ideological enemies, or raid and attack indiscriminately. All interactions and laws are player enforced, with the help of plugins that have defined the genre since it's inception as CivCraft. You can view the player run wiki here, the player run map (with rail lines, nation borders, ect) here, and the player run newsletter here. The wiki also contains a New Player Guide! Every new player gets one free teleport within 24 hours of joining, make it count! Basic information under the cut.

The primary plugins used on CivMC to make it unique are NameLayer, Citadel, and Exile Pearl. FactoryMod also deserves a mention here.

Exile Pearl is arguably the most interesting mechanic, which allows you to kill another player with an Ender Pearl on your hotbar. This will imprison said player in the Nether, and also imposes restrictions on their gameplay. Pearls degrade however, and player "Essence" is required to keep them fueled. Essence is granted on a daily basis to players after being online for 30 minutes. Requiring a somewhat active nation to keep others imprisoned. Pearled players are kept in vaults, disgustingly large and complex obsidian structures meant to have maximum security.

NameLayer acts as the base structure for many other plugins on the server. It allows players to make groups, with different ranks in said group having more, or fewer, permissions within a group. Such as who can buy from your shops, open doors and chests, or who can chat in said group. This last one is important, as the default chat range is only 1000 blocks. However there is a public global chat, just type "/global" after joining to participate, and "/local" to revert back.

Citadel is a reinforcement plugin that will make your chests harder for nefarious actors to break into, your buildings more resilient to attacks, and allows you more peace of mind during your off hours. Individual blocks, chests, doors, etc can be locked with reinforcement materials. Each material requires a set number of breaks before the block will drop. Stone is 50, iron ingots are 300, and diamonds are 2000. Virtually every build in the game is reinforced with stone, more expensive materials are reserved for more important things, like chests. NameLayer hooks into Citadel to allow granular access control for almost everything!

FactoryMod allows you to create small structures known as factories, made from a furnace, crafting table, and a chest. Factories allow for more complex recipes and items not found in vanilla minecraft. More efficient recipes than in vanilla minecraft (32 gold ore to 48 ingots, 64 cobble to 96 stone!). And cheaply available decorative blocks to make your builds nice.

There are plenty of other mechanics I haven't touched upon, like brewing alcohol for unique potion effects, how crops grow (or don't!) in certain biomes, the distribution of ores, or how you can see who broke into your home and stole all your crafting tables. See the wiki for more information on game mechanics! There are plenty of nations on the server, which I would recommend joining before trying to make your own. One of my personal favourites is the nation of Pavia, locted at (800, -3000)

Pavia is an elective meritocracy, comprising of a Prime Minister and his Cabinet, elected by the Nobility of Pavia. Pavia's territory is divided into distinct classes outlined by the foundational law of the country, the Magna Pavia. These classes administrate their own territories with varying states of autonomy and all add their own story to Pavia's ever-growing lore & history! Pavia is famous for its incredible and sprawling architecture as well as its economy, home to the largest Bank on CivMC and one of the server's most extensive shopping districts. There is a tutorial open to anyone to learn every guide and plugin which is located in the Pavia townhall, if you wish to use the server tutorial head to (+800 , -3065) inside the building on the ground floor. If you are new to CivMC, it is recommended you start off by settling in the Bedford Commons, a city just outside the capital's walls. The coordinates are (+1000, -2800).

Happy Leap Day! 🐸

I'm writing up a guide for learning how to stay consistent when learning programming and this section made me laugh a bit because the person who said this word for word to me was my C# + Java teacher during my apprenticeship era and we had online classes (cause of COVID) so he would literally scream this down his mic to make us remember (repetition of phrases does actually stick in your head) and now I can proudly do the same non-verbally in my guide :p

I stand on business with this opinion- no fact. No passively watching YouTube tutorials for learning how to program.

[vexacarnivorous]

hello! i'm a new college student, and the syllabus says c and java are the languages they'll teach in the first two semester. could you direct me to some resources or someone who could help if you're not interested? no pressure, thank you!

hey! i'm unsure how helpful my advice will be because i've only dabbled in c and java, but i can certainly point you in the right direction. i know how much of a pain searching for beginner-friendly resources can be. good luck in your studies, and welcome to college!

GENERAL:

there are a lot of community-curated resources in the tag awesome-list on github. check it out here, and have fun going through them all because you'll never escape

w3schools is great for referencing

this basically gives you the equivalent to a bachelor's degree in computer science and is completely free

freecomputerbooks has a c and java language category. i can't recommend you specific books though

i only discovered wikiversity was a thing when i became an adult, which is a right shame. there's free courses for computer science and information technology

C LANGUAGE:

harvard has an online course called cs50 you can find for free on freecodecamp's youtube channel (the cs50 website also includes notes for the course). it introduces computer science (and the basics of c) pretty nicely

wikiversity's "C Programming" and its wikibook companion

freecodecamp's "C Programming Handbook for Beginners"

if you ever get confused about pointers: A Tutorial on Pointers and Arrays in C

commonly asked c programming questions & answers are in this FAQ

the article "What A C Programmer Should Know About Memory" (a bit more intermediate)

JAVA LANGUAGE:

the wikibook "Java Programming"

wikiversity's java portal has links to both internal and external java resources. i'd recommend looking through it

freecodecamp's "The Java Handbook – Learn Java Programming for Beginners"

freecodecamp's online course "Java Programming for Beginners"

dev.java's "Learn Java"

the free training course offered by oracle

if anyone else has anything to add, feel free to chime in! i hope this helps :)

[apollos-polls]

regarding getting a coding job, i guess the main tips would be, look up a language that's in demand generally (C#/.NET, Java, React and other JavaScript libraries, python tend to be the most popular) and look into self-learning online; not just tutorials, but Reddit daily programming challenges, software developer interview examples and things like that :) coding bootcamps can be useful too if you can afford them! once you get the basics under your belt, apply to as many grad roles as you can find (and anyone who says you need a college degree? they're lying)

you can create a GitHub account for free to push any coding projects you create, which also helps familiarise you with version control (key in any software role), and can be really good to show potential employers as a dev portfolio of sorts

good luck!!

Thanks anon! I got a CS degree a bit ago and I've been self-learning and working on projects since then, but got NO luck in terms of jobs 😔

I'll def try out the daily challenges tho!

I really appreciate it, thank you so much 🥺
