Infinity Engine 3D Game Tutorial

Welcome to the Infinity Engine 3D Game Tutorial! This guide will walk you through building a 3D game from scratch using Infinity Engine. You’ll learn to set up the environment, load a 3D model, add interactions, and render a basic 3D world.

Getting Started

Before you begin, make sure you have the following:

Infinity Engine Installed

Ensure your engine setup is installed and functioning correctly. Refer to the Infinity Engine installation guide for troubleshooting.

A 3D Model

You’ll need a .glb, .obj, or .fbx file for your game. Free models are available on platforms like Sketchfab and CGTrader.

Python Installed

Install Python 3.x on your system. You may need additional libraries for enhanced functionality. Run this command to install required dependencies:

bash
Copy code
pip install ursina pygame 

Step 1: Setting Up the Environment

1. Initialize the Engine

Start by importing necessary libraries and initializing Infinity Engine.

python
Copy code
import pygame as Infinity2D from ursina import *  # Initialize Ursina Engine app = Ursina() 

2. Set Up the Game Window

Create a window for your game using Infinity Engine's display module.

python
Copy code
WIDTH, HEIGHT = 800, 600 screen = Infinity2D.display.set_mode((WIDTH, HEIGHT)) Infinity2D.display.set_caption("Infinity Engine 3D Game") 

Step 2: Importing a 3D Model

1. Load the Model

Import a 3D model into the game.

python
Copy code
model = Entity(model='path_to_model.glb', scale=(1, 1, 1), position=(0, 0, 0)) 

2. Adjust Model Properties

Customize the model’s size and position in the 3D world.

python
Copy code
model.position = Vec3(0, 1, 0)  # Position the model at (x, y, z) model.scale = 2  # Double the model size 

Step 3: Adding Lighting and Environment

1. Add Lighting

Use a directional light to illuminate the scene.

python
Copy code
light = DirectionalLight() light.look_at(Vec3(0, -1, -1)) 

2. Add a Ground Plane

Add a plane to represent the ground.

python
Copy code
ground = Entity(model='plane', scale=(10, 1, 10), color=color.green) 

Step 4: Player Movement

1. Add Player Controls

Use Ursina's FirstPersonController for player movement.

python
Copy code
player = FirstPersonController() 

2. Attach Camera to Player

Ensure the camera follows the player’s movements.

python
Copy code
camera.parent = player 

Step 5: Running the Game

1. Add Sky Background

Use a skybox for the game’s background.

python
Copy code
sky = Sky() 

2. Start the Game Loop

Run the game using app.run().

python
Copy code
app.run() 

Complete Example Code

Here’s the full example code ready for your game:

python
Copy code
from ursina import * import pygame as Infinity2D  # Initialize the Ursina Engine app = Ursina()  # Main Screen WIDTH, HEIGHT = 800, 600 screen = Infinity2D.display.set_mode((WIDTH, HEIGHT)) Infinity2D.display.set_caption("Infinity Engine 3D Game")  # Add Environment light = DirectionalLight() light.look_at(Vec3(0, -1, -1)) ground = Entity(model='plane', scale=(10, 1, 10), color=color.green) sky = Sky()  # Add 3D Model model = Entity(model='path_to_model.glb', scale=(1, 1, 1), position=(0, 0, 0))  # Add Player player = FirstPersonController() camera.parent = player  # Run Game app.run()
