Sub -Topics 1. Downloading and installing GamerMaker Studio 2. Breaking down the interface - where to find what/what does this button do?
Chapter 2: Chapter 2: Introduction to GML Chapter Goal: This chapter serves as an introduction to GML, what is new in GML in GMS2 and how to get started with writing code. This chapter will not be in-depth and will not cover all the functions available in GMS2, but will be a language overview by creating a small game. No of pages: 40
Sub - Topics 1. Writing code in GMS2 - Scripts, Objects and Events 2. Data Types and Variables and Scope 3. Assignments and Expressions 4. Arrays and Data Structures 5. Language Features and Program flow control statements 6. Functions
Chapter 3: Making your first game Chapter Goal: The goal of this chapter is to start on our main game, but a single player version of it. It starts off with a game design process where we plan well in advance what we are going to do; and moves on to talk about how to translate ideas from paper to a prototype. We then move on to build the game from the prototype, adding more complex behaviors and features. No of pages : 70
Sub - Topics: 1. Game Design 101 - a reusable process/framework 2. Planning your game 3. Rooms, Sprites and Objects 4. Building a single player version 5. Getting the core mechanics in place 6. HUDs, Menus and more
Chapter 4: An introduction to NodeJS Chapter Goal: This chapter introduces the reader to NodeJS and how one can get started with it. Some level of JavaScript knowledge is required. We will setup a small server and work with Express. No of pages: 15
Sub - Topics: 1. Installing NodeJS 2. Your first program 3. Extending the server with express
Chapter 5: Talking to your server Chapter Goal: This chapter focuses on integrating our game with our NodeJS server. At first, we will create a feature which reads a list of news updates from the server and display it when the game loads. As a second exercise, we try to read and post a high scores table. No of pages: 40
Sub - Topics: 1. Getting data - A daily news and updates ticker 2. Setting data - A simple high scores page
Chapter 6: Introducing the multiplayer game Chapter Goal: In this chapter, we will implement the game logic on the server - finding a player, starting a game session, playing the game, syncing data etc. No of pages: 50
