Minecraft was purchased by Micro$oft. When you pay to play Minecraft you are no longer supporting an independent developer. Do not pay for Minecraft because you will be paying Micro$oft.

Play Minecraft for free

Use Mineshafter. This allows you to play Minecraft on a PC for free with most of the features and latest version.

Windows

Troubleshooting

Everything is Black or Invisible

Black shaders. This is a condition where the visual elements appear black or invisible. It is due to corruption in the shader elements in the Minecraft cache. All your minecraft data settings are stored in:

%appdata%\.minecraft\

By deleting the contents of that folder you will reset everything stored locally including all the visual element cache and graphic settings. This is known to resolve the black and missing shader issue.

Minecraft World is Too Dark

Day or night, with the brightness up, you note that the world still seems dark or there is not enough contract between objects. This is related to graphic card compatibility.

In the game try:

1. Press Esc
2. Click Options
3. Click Video Settings
4. Turn Smooth Lighting "Off"

This will improve the "contrast" issue. It may not resolve the lack of brightness or gamma.

To improve gamma which will allow you to see things better, try the following:

Close the game. In Windows at the start menu

1. Start -> Run -> type "%appdata%\.minecraft\" and press enter
2. Locate the file "options.txt" and open in notepad
3. In the options.txt file locate the line "gamma:0.90140843". Just search for the word "gamma" as the number in the parameter may be different on yours.
4. Change the number to a larger number. save. exit.

You can experiment with different fraction and whole number values. Apparently the highest number value, according to oliversmith7 of planetminecraft.com is 1000.0

Linux

Ubuntu

Troubleshooting:

Minecraft running slow - my linux minecraft was running on 12 to 14 fps. i have installed hava 7,java 8, openjdk 7 and everything requires but minecraft stil slow

This command should tell you what is currently providing the Java virtual machine (java) and the Java compiler (javac):

file /etc/alternatives/java /etc/alternatives/javac

This assumes the "alternatives" system is working properly, which might not be the case, depending on how Java has been "messed up" in the past. To check this, run:

file `which java javac`

If the alternatives system is working correctly and being used by Java, then you should see:

/usr/bin/java: symbolic link to `/etc/alternatives/java' /usr/bin/javac: symbolic link to `/etc/alternatives/javac'

Set up Minecraft server on Ubuntu

First install Oracle Java

Run the following commands in this order to add the PPA, update the source list and then install java:

sudo apt-add-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer

Then run this to check what version you have installed:

java -version

Start server

java -Xms1G -Xmx1G -jar /usr/local/minecraft/minecraft_server.1.8.8.jar nogui

You will see

[11:41:12] [Server thread/INFO]: Starting minecraft server version 1.8.8
[11:41:12] [Server thread/INFO]: Loading properties
[11:41:12] [Server thread/WARN]: server.properties does not exist
[11:41:12] [Server thread/INFO]: Generating new properties file
[11:41:12] [Server thread/WARN]: Failed to load eula.txt
[11:41:12] [Server thread/INFO]: You need to agree to the EULA in order to run the server. Go to eula.txt for more info.
[11:41:12] [Server thread/INFO]: Stopping server
[11:41:12] [Server Shutdown Thread/INFO]: Stopping server

The latest version has a stupid eula hoop you have to jump though

vi eula.txt

change

#By changing the setting below to TRUE you are indicating your agreement to our EULA (https://account.mojang.com/documents/minecraft

_eula).

#Wed Aug 05 11:41:12 CDT 2015
eula=true

The eula.txt was created by the server the first time you tried to run it. Now that you changed the value to "true" save the text file, get out, and run the server again.

When the server is up and running you’ll see a stream of notices in the console window. You can execute commands that control the serer and players.

SERVER MODS: You can inject Forge mod loader into the Minecraft server. Within the folder, run the "forge.*.universal.jar" file. You need to accept the EULA. Open up the freshly created EULA.txt and edit the false to true. Remember, vanilla clients can’t join modded servers. Join a matching version number installation of Minecraft with Forge installed, but without any mods loaded, which will mirror the state of the server. Everyone that joins your server will need to have those mods installed; the /mod/ folder of the client and the/mod/ folder of the server should be mirrors of each other.

Gameplay

Here is the very basic crafting and play guide. This game has a great deal of crafting that is not covered. You can get started with the principles necessary to learn the game and from there explore the more complex aspects on your own.

Printable Basic Crafting Table

Color Basic Crafting Table (more detailed)

Redstone Circuit

Command Block

The Command Block is a redstone powered block that will execute commands primarily used on multiplayer servers and in custom maps. This block cannot be crafted and only server administrators are allowed to place them.

Command blocks can only be obtained when cheats are activated, and can only be used in creative mode, preventing survival players in a server from accessing "staff" abilities. Command blocks are invincible outside of creative mode. With Command blocks you can preform commands that players can not preform.

To get a command block using cheats, type

/give @p minecraft:command_block <amount>
