Introduction

These are some Procedural Content Generation (PCG) projects, implemented with C# and simulated in Unity. Advised by professor Greg Turk. Github repo: PCG-projects.

Projects are as follows:

• Dungeons
• Buildings
• Vehicles

Dungeons

Requirements:

• .Net: .Net 4.x
• Unity Editor: 2020.3.25f1
• Working on MACOS

Game Control:

• WASD	up/left/down/right for first person mode moving. (A & D for rotating, W & S for forwarding/backing)

• WASD	up/left/down/right for third person mode moving. (A & D for going left/right, W & S for forwarding/backing)

• Space for first and third person mode switch. (You’ll be automatically transmitted to start point if switched from third person mode to first person mode)
• Press ‘z’ when nearing pillars whose top light is blue for transmitting you to the start point (where there’s a pillar whose top light is green).

Script Parameters introduction:

• Seed: seed for random function.
• Grid_width: width of the whole dungeon.
• Grid_height: height of the whole dungeon.
• CA_iteration_num: number of iterations for running cellular automation.
• Init_fill_prob: initial ratio of filled grids for cellular automation.
• Grid_size: size of each grid.
• Wall_height: height of the dungeon walls.
• Chest_ratio: ratio of chests in the whole dungeon.
• Rock_ratio: ratio of piles of rocks in the whole dungeon.
• Teleportation_ratio: ratio of teleportation pillars in the whole dungeon.
• Human_height: height of camera for first person mode.
• Height_3: height of camera for third person mode.
• Is_collistion_detection: open collision detection or not.

Requirements:

• All finished.
• Special explanation: the texture made by myself is used on the chests.

Efforts:

• When in first person mode, open the top of a treasure chest when the player comes near to it.
• When in first person mode, close the top of a treasure chest when the player leaves it.
• Create teleportation pillars for convenient teleportation.
• Designed 3 modes of piles of stones. Add much randomness to each mode, which makes piles of stones more diverse.
• Change movement method for third person mode.
• Add collision detection (only if Is_collistion_detection enabled): but currently with some bugs (you cannot press S/down when stopped by the wall, you should turn left or right first and then go forward.)

Buildings

Version I use:

• .Net: .Net 4.x
• Unity Editor: 2020.3.26f1
• Working on Ubuntu20

Run the code: No special demonstration, just run the code is enough. The Main.cs has been attached to the GameObject.

Script Parameters introduction:

• Seed: seed for random function.
• Num of Building: Number of buildings to be shown.
• Building Distance: Distance between shown buildings.
• Footprint Length: Used to decide the size of the building.
• Cell Length: Used to decide the density of wall blocks, windows and doors.

Requirements:

• All finished.

Efforts:

• Make some windows and doors opened in some random angles.
• Add windowsill.
• Add long steps for doors.
• Add porch for each door. Each porch has cylinder pillar and roof.
• Add bedroom and settingroom behind the windows and doors.
• Use random textures for different part of the building.
• Use diffent styles of windows and doors.

Vehicles

Introduction: I created spacecrafts (Vehicle) in this project.

Usage:

• The final.unity is the one can be run directly, I have attached the Main.cs to an EmptyObject (you only need to modify the seed to get different vehicles).

Details of my work:

1. All required parts completed
2. My efforts:
   • Used subdivision surface for nearly all surfaces.
   • Two main body parts(wing & tail) of the spacecraft are animated.
   • Two main body parts(wing & tail) of the spacecraft are swappable.
     1. Wing: Designed 3 variations for wing.
     2. Tail: Designed 4 variations for tail.
   • Add texture (steel material) to two types of wing.
   • Make camera moveable.
   • Many parts of the spacecraft shows variation in size(e.g., wings, tails, etc.).
   • Make smooth joins between tail and body.
