Description

1. Understanding Game Design & Planning

Before we start building, we will go over the key elements that make a great escape game:

==> How to structure an engaging escape room experience

==> Designing puzzles that are fun and challenging

==> Placing clues and items logically to guide the player

2. Creating the 3D Game Environment

You will learn how to build a realistic house where the game takes place. This includes:

==> Setting up rooms, furniture, and decorations

==> Creating interactive objects like doors, drawers, and secret compartments

3. Implementing Puzzle Mechanics

The core of your game will be the puzzles! You’ll learn how to add different types of challenges, such as:

==> Item-based puzzles – Finding a key to unlock a door

==> Code puzzles – Using clues to figure out a combination lock

==> Object interactions – Moving furniture to reveal hidden items

==> Logic puzzles – Arranging objects in the right order to trigger an event

4. Player Interaction & Inventory System

We will implement systems that allow players to interact with objects, pick up items, and use them later. This includes:

==> Clicking on objects to examine and collect them

==> Creating an inventory system to store and use collected items

==> Combining items to solve more complex puzzles

5. Game Logic & Scripting

To bring everything to life, we will use scripting (such as C# in Unity) to:

==> Control how objects react to player actions

==> Implement timers, triggers, and conditions for puzzles

==> Manage game progress and story elements
