Unity 3D Object Physics Simulation Game

A Unity 3D physics simulation game where you can control objects, create dynamic elements, and observe physics interactions in real-time.

Game Description

This is a 3D physics sandbox game built in Unity where players can:

• Control different objects (capsules, spheres) using keyboard input
• Create small physics objects (cubes, spheres, cylinders) that interact with each other
• Adjust object speeds and observe realistic physics collisions
• Navigate the 3D environment using mouse look controls

Controls

Object Movement

• Arrow Keys: Move the SPH (sphere) object
  • Left/Right arrows: Move along X-axis
  • Up/Down arrows: Move along Y-axis
  • Plus/Minus (or Keypad +/-): Move along Z-axis

Capsule Movement

• W/S: Move forward/backward
• A/D: Move left/right
• E/X: Move up/down

Camera Controls

• Mouse: Look around (first-person camera)
• Mouse cursor is locked during gameplay

Object Creation & Speed

• Space: Create random objects (cubes, spheres, cylinders)
  • Single press: Creates one object
  • Hold Space: Continuously creates objects after 0.5 seconds
• > (Period): Increase object speed
• < (Comma): Decrease object speed
• Speed range: 1 to 150 units

Features

• Random Object Properties: Each created object has:

  • Random color (RGB values)
  • Random size (1-10x scale)
  • Random initial velocity direction

• Physics Simulation: All objects use Unity's Rigidbody physics system for realistic collisions and movement

• Real-time Speed Control: Adjust the speed of newly created objects during gameplay

Technical Details

• Built with Unity Engine
• Uses C# scripting
• Implements Unity's physics system (Rigidbody components)
• Real-time input handling for smooth controls

Scripts Overview

• SPHMovement.cs: Controls sphere movement with arrow keys
• CapsuleMovement.cs: Controls capsule movement with WASD keys
• MouseLook.cs: Handles camera rotation with mouse input
• CreateSmallObjects.cs: Manages dynamic object creation
• Object.cs: Defines properties and behavior of created objects
• ObjectsSpeed.cs: Manages speed control system

Installation & Setup

1. Clone this repository
2. Open the project in Unity (version compatible with the project)
