Chapter 1. Introduction
Minecraft is a 3D game that involves breaking and placing blocks to obtain materials. These materials can then be used to build or craft new items and tools. These, in turn, can be used to harvest more types of blocks. The game also contains entities, which are dynamic moving objects in Minecraft (e.g., cows, pigs, and horses). Entities that are hostile are called monsters (e.g., zombies and creepers). Bosses are monsters that are very hard to defeat. Appendix A provides more details on how to get started with the game of Minecraft.

These modifications can change certain aspects of how the game was originally written (e.g., changing the size of a TNT explosion). In addition, they can add content to the game to alter gameplay (e.g., new blocks, items, and smelting recipes).

Minecraft also allows multiple players to join a server. This is called multiplayer mode. It’s unusual to run a server on your own machine. However, this book will explain how to make mods and run them on your Minecraft client ...
