Introduction

A tower-defense game is a type of strategy game where players will place down “towers”, usually with a form of in-game currency that will defend against a set of enemies. If you fail to defeat the enemies, you will typically lose health - when you reach zero, it’s Game Over.

In Bloons Tower Defense, the towers are monkeys, and the enemies are balloons, which spawn in rounds and travel along a pre-determined path. Your goal as a player is to strategically spend your currency while placing towers in effective locations, using their special abilities to win the game!

In this workshop, we will cover the fundamental aspects of a tower-defense game, and in future workshops, we will cover special abilities and ways that you can customize your game to make it your own!

In the second part of this workshop, you will learn how to create multiple types of towers, unique abilities, projectiles, and more!

This includes:

• How to use IDs to add multiple types of towers and projectiles
• How to implement a full currency system and adjust the cost of different towers
• How to create a custom tower tracking system
• How to use pre-built template code to create projectiles

You will need to download Processing 4.0 from https://processing.org/download, or have Processing 3 or newer installed.

In our workshop, we will be adding code to several templates, which you can download below.
