Action RPG Tutorial Overview

Introduction

• Action RPGs have a rich history:
  • Pioneers: Adventure for Atari.
  • Golden Era: Super Nintendo.
  • Modern Scene: Thriving indie games today.
• Objective of the tutorial: Create an action RPG using Unity.
• Placeholder art will be used during development for prototyping.

Getting Started with Unity's Tile Map System

1. Create a Tile Map:

   • Navigate to the hierarchy, right-click, select 2D Object > Tile Map (rectangular).
   • A grid appears on the screen to start building the world.
   • Rename the Tile Map to Ground.

2. Creating a Tile Palette:

   • If a tile palette isn’t created automatically:
     • Go to Window > 2D > Tile Palette.
     • Dock the palette window at the bottom.
     • Create a new palette called RPG Palette and save it in assets.

3. Creating Tiles:

   • Right-click in the assets folder, go to Create > 2D Sprites > Square.
   • Drag the square into the palette and save it in assets.
   • Click on the ground layer and change its color (preferably to green) using the paint tool.
   • Use the paint bucket tool to fill in the area.

4. Using a Color Palette:

   • Import a color palette and enlarge it for better visibility.
   • Use the dropper tool to select desirable colors for your game.

Adding Layers to the Map

1. Add Water Layer:

   • Create a new tile map for water (similar process as ground).
   • Change the color for the water layer using the dropper tool to select a nice blue color.
   • Paint in features like rivers and oceans.

2. Adding More Layers:

   • Repeat for other features (trees, mountains, etc.).
   • Make sure to set the order in layer for trees to be above ground to appear correctly.
   • Create layers for beaches, mountains, snow, etc., to develop the world.

Implementing Colliders

1. Making Areas Unwalkable:
   • Click on the layer you want to make unwalkable (e.g., water).
   • In the inspector, add a component called Tilemap Collider 2D.
   • This will create colliders for all tiles in that layer, making them impassable.
   • Repeat this for trees, mountains, and snowy mountains.

Conclusion

• A preliminary world has been created.
• Next tutorial: Creating a character that can walk around the world.
