Survival is a game mode that is available in all versions of Minecraft. Survival mode lets you search for resources, craft, gain levels, and have a health bar and a hunger bar. When you create a world in Minecraft, you can easily switch back and forth between Creative and Survival modes using the /gamemode command.

Let's explore how to switch the game mode to Survival using the /gamemode command.

How to Enter the Command

1. Open the Chat Window

The easiest way to run a command in Minecraft is within the chat window. The game control to open the chat window depends on the version of Minecraft:

  • For Java Edition (PC/Mac), press the T key to open the chat window.
  • For Pocket Edition (PE), tap on the chat button at the top of the screen.
  • For Xbox One, press the D-Pad (right) on the controller.
  • For PS4, press the D-Pad (right) on the controller.
  • For Nintendo Switch, press the right arrow button on the controller.
  • For Windows 10 Edition, press the T key to open the chat window.
  • For Education Edition, press the T key to open the chat window.

2. Type the Command

In this example, we are going to change the gamemode to Survival using the following command:

Type the command in the chat window. As you are typing, you will see the command appear in the lower left corner of the game window. Press the Enter key to run the command.

Once the cheat has been entered, the game mode will be updated to Survival:

You will see the message 'Your game mode has been updated' appear in the lower left corner of the game window. Also, your health meter and hunger meter will appear above the hotbar.

Now you are in Survival game mode in Minecraft! You will have to gather resources and mobs will attack you.

Minecraft.net Communication[edit]

Heartbeats[edit]

To be able to connect to a server in Minecraft Classic from the Server List, a server must broadcast to minecraft.net a so-called 'heartbeat' every few minutes.

The stock server broadcasts this heartbeat every 45 seconds.

A 'heartbeat' takes the form of an HTTP request to https://minecraft.net/heartbeat.jsp.After sending a heartbeat, the URL for the server is returned. Minecraft free edition. Hilux 1984 workshop manual.

It is critical to a successful heartbeat that you leave out the 'www' in the HTTP request, as you are going to be targeting it as a URI, not a URL.

It can be a GET or POST request. A table of the required parameters is below:

NameDetails
portPort number of the server. This is usually 25565
maxMaximum number of players on the server
nameThe name of the server
publicWhether the server is public (i.e. appears in the lobby) or not. Can be True or False, in that capitalization.
versionMinecraft version, this should be 7
saltA random, 16-character base-62 salt
usersNumber of users connected to the server

The simplest way to send a heartbeat is to open a TCP socket to port 80 on minecraft.net, and send the following (with the values changed, obviously):

GET /heartbeat.jsp?port=25565&max=32&name=My%20Server&public=True&version=7&salt=wo6kVAHjxoJcInKx&users=0, plus a CRLF(Carriage-return and Line feed).

Make sure any strings, like name, are escaped.

If everything goes well, in the response body you'll receive a URL to the server. Otherwise you'll get a nice HTML error message. There aren't any HTML headers to parse, as the HTTP version is not specified so HTTP/0.9 is used, which does not have headers.

User Authentication[edit]

The 'key' provided when a user joins the server can be compared to the MD5 checksum of the server's 'salt' plus the username to verify that the user is logged in to minecraft.net with that username. This is useful for establishing enough trust of the name provided to ban or op the player by name.

Minecraft Classic Codes Roblox

This is also the way that Notch prevents 'cracked,' or pirated, clients from accessing online servers. When a cracked client tries to connect to an online server, an error will come up at the connection screen saying, 'Failed to Connect: User Not Premium'

Note: This means that you should make sure your 'salt' is kept a secret and shared only with heartbeat.jsp. If your server's 'salt' is visible anywhere to users, it is trivial for users to produce valid-looking 'key's without being logged in to minecraft.net.

Packet Protocol[edit]

Every packet starts with a byte representing the Packet ID.

Protocol Data Types[edit]

TypeSize [bytes]Description
Byte1Single byte integer (0 to 255)
SByte1Single byte signed integer (-128 to 127)
Short2Signed integer, network order (-32768 to 32767)

0x05Set BlockPacket IDByteSent when a user changes a block. The mode field indicates whether a block was created (0x01) or destroyed (0x00).

Block type is always the type player is holding, (even when deleting).

Client assumes that this command packet always succeeds, and so draws the new block immediately. To disallow block creation, server must send back Set Block packet with the old block type.

The XYZ coordinates of the block are just integers representing the coordinate of the block. (As opposed to player coordinates where the lower 5 bits are fractional coordinates)

Player coordinates are fixed-point values with the lowest 5 bits representing the fractional position (i.e. divide by 32 to get actual position in terms of block coordinates). The angle parameters are scaled such that a value of 255 would correspond to 360 degrees.

Player Position[edit]

Fixed Point[edit]

Player position is represented via X, Y, and Z fixed-point coordinates. The fractional portion is 5 bits, so dividing the short integers received in position update packets by 32, you will have floating point coordinates for the player. This position corresponds to the center of the client viewport.

Standing On Things[edit]

Minecraft Classic Combat

The bottom of the player's feet is located 1.59375 (fixed-point: 51) units below the center of the viewport, so to position the player on top of a particular block you could send a teleport (0x08) packet specifying a Y value based on the block position as: (Y x 32 + 51)

Orientation[edit]

A yaw value of 0 means the player is facing in the Z- (negative Z) direction. This value increases in a clockwise direction as seen from above. If we call the negative Z direction 'North', then a yaw of 64 means 'East', 128 means 'South', and 192 means 'West'.

A pitch value of 0 means level and this value increases in a downward direction. 64 is down, and 192 is up. Values of 65 to 191 should never occur because the player cannot look further up or down than the 64 → 0, 255 → 192 range. However, the Minecraft Classic client does not ignore invalid values, so it is possible to make players' heads 'upside-down'.

Color codes[edit]

Minecraft Classic Creative

This article is about classic server protocol. For the updated color codes used in the current version of Minecraft, see Formatting codes.

Messages sent from the server to the client can contain color codes, which allow coloring of text for various purposes.

An ampersand symbol (&) followed by a hex digit in the message tells the client to switch colors while displaying text. The current version of the game uses a section (§) symbol, but the 0.30 version uses ampersands. For the formatting codes for the current version of the game, see Formatting codes.

Color coding at the start of the message will only work if the player ID byte is less than 127. If it's 127 or higher, the game automatically adds &e before the message, making it yellow. However, color codes after the first character still work. If you use an ID below 127, it doesn't add a color code, so the ones you use will work.

Hex digit to color mapping.
