Tower Defence Game

A simple tower defense game built with Unity. This repository contains the Unity project, gameplay scripts, scenes, and assets used to prototype tower placement, wave-based enemy spawning, and projectile attacks.

Features

• Buildable nodes with hover material and position offsets (Scripts/Node.cs)
• Turret placement and firing projectiles (Scripts/Arrow.cs)
• Enemy prefabs and wave-based spawning with scaling difficulty (Scripts/EnemySpawner.cs)
• Enemy movement along waypoints and life handling (Scripts/EnemyMovement.cs)
• Range indicator toggling for towers (Scripts/ShowRange.cs)
• Basic materials, sprites, and animator controllers included in the project

Setup / Getting started

1. Prerequisites

   • Install Unity Hub: https://unity.com/download
   • Install a Unity Editor version compatible with the project (recommended: Unity 2021.3 LTS or later). If you have the project on disk, check ProjectSettings/ProjectVersion.txt for the exact version.
   • Git (for cloning the repository)

2. Clone the repository

git clone https://github.com/Jamwilltim/Tower-Defence-Game.git
cd Tower-Defence-Game

3. Open the project in Unity

   • Launch Unity Hub
   • Click Add, select the repository folder you cloned
   • Open the project with the installed Unity Editor version matching the project's ProjectVersion.txt

4. Open the main scene

   • In the Unity Editor, open Scenes/MainScene.unity
   • Press Play in the Editor to run the scene

Controls and Gameplay

• Left-click on buildable Nodes to place a turret (if you have enough currency)
• Towers will target enemies and fire projectiles automatically
• Enemies follow waypoints and reduce player lives if they reach the end
• Waves increase in size/difficulty according to the values in Scripts/EnemySpawner.cs

Project structure (high level)

• Assets/
  • Scenes/ - Unity scenes (MainScene.unity)
  • Scripts/ - C# scripts (Node.cs, EnemySpawner.cs, EnemyMovement.cs, Arrow.cs, ShowRange.cs, etc.)
  • Prefabs/ - Prefabs for turrets, hover blocks, etc.
  • Sprites/ - Sprite sheets and animation controllers
  • Materials/ - Material assets (ground.mat)

Common configuration values

• EnemySpawner contains configuration you can tune in the Inspector or directly in the script:
  • baseEnemies
  • startCountdown
  • enemiesPerSecond
  • timeBetweenWaves
  • difficultyScalingFactor
  • enemiesPerSecondCap

Troubleshooting

• Missing or mismatched Unity version: If the Editor reports an incompatible version, install the matching Editor via Unity Hub or use the closest LTS release.
• Missing packages: Open Window > Package Manager and add any required packages listed in Packages/manifest.json.
• NullReferenceException or missing references: Inspect the GameObjects in the scene and verify required components (e.g., sprite renderers, references to prefabs, spawn points) are assigned in the Inspector.
