RAMP 2023 - Building a Doom map

Introduction

This tutorial guides you through the process of creating a basic Doom map using the Boom format. Whether you're a complete beginner or looking to expand your mapping skills, this step-by-step guide will help you build a functional level inspired by Doom's classic gameplay.

Step 1: Setting Up the Environment

• Open your Doom mapping tool (e.g., Ultimate Doom Builder).
• Select the Doom 2.1.0 base resource and create a new map.
• To start drawing, press Ctrl + D or activate the jaw lines mode.
• Click to create your first vertices, forming the outline of your first room.

Step 2: Creating Your First Room

• Press Q to enter 3D preview mode and use ESDF keys to navigate.
• Switch to vertices mode by pressing V, then drag the vertices to adjust the room size.
• Select the Things mode and double-click to add a Player 1 start. Set the facing direction to the left.

Step 3: Expanding the Map

• Create additional rooms by dragging vertices to expand the layout.
• Incorporate verticality by adjusting ceiling heights using the scroll wheel.
• Add enemies by selecting the Things mode, placing "former humans" (zombie men), and other monsters as desired.

Step 4: Adding Doors

• In sector mode, create a door using Shift + D.
• Choose door textures and define action specials for the door (e.g., open, close).
• Ensure the door is properly aligned to allow for seamless movement.

Step 5: Incorporating Gameplay Elements

• Add items such as clips and shotgun shells within the map to reward players.
• Use Ctrl + right-click to apply textures to walls and other surfaces.
• Create a lift by making a new sector and setting it up with the appropriate action (e.g., lift, lower, raise).

Step 6: Designing Caves and Corridors

• Draw jagged formations to create caves, giving a more natural look.
• Ensure the cave walls vary in height and shape for interest.
• Use mid-textures to add depth and make sections impassable if needed.

Step 7: Adding Secrets and Traps

• Design secret areas by creating hidden doors or alcoves.
• Use actions to control player interactions with switches and doors.
• Ensure traps are set up to surprise players, enhancing gameplay tension.

Step 8: Finalizing the Map

• Playtest your map using Ctrl + F9 to check functionality.
• Adjust brightness levels for different areas to set the mood.
• Add finishing touches like textures and decorations to enhance aesthetics.

Conclusion

You've now built a basic Doom map that includes rooms, enemies, items, and interactive elements. This foundational knowledge serves as a stepping stone for more complex designs.
