Tower Defense

A 2D tower-defense game written in Java with Swing/AWT. Originally a high-school project (NetBeans, Java 1.5); this repository has been re-laid out into a standard Gradle project. The game logic is unchanged — only the build, package structure, and resource locations were modernized.

Authors: Jay Honnold, Sam Miller

Requirements

• A JDK is needed to run Gradle, but you do not need to install Java 25 yourself — the build declares a Java 25 toolchain and Gradle auto-provisions a matching JDK via the foojay resolver.

Running

./gradlew run

This launches an 800×600 window. The run task uses data/ as its working directory so the game can read map.txt / level.txt and read/write the high score in data.txt.

Building

./gradlew build

Project layout

src/main/java/com/towerdefense/   # game source (single package)
src/main/resources/               # bundled assets loaded from the classpath
    icon.png
    images/                       # sprites, tiles, UI
data/                             # runtime text data (read/written at runtime)
    map.txt  level.txt  data.txt
art/                              # design sources (*.psd), not bundled

Image assets are loaded from the classpath. The three .txt files in data/ are read (and data.txt written) as ordinary files via the EasyReader / EasyWriter helpers, which is why they live outside the classpath.

Map format (data/map.txt)

First line is width height; the grid follows, one tile code per cell. The top row is left blank (on-screen text is drawn there). Tile codes:

Code	Meaning
0	Empty
1	Horizontal road
2	Vertical road
3	Left to down
4	Up to right
5	Up to left
6	Right to down
7	Crossroads
8	Start (facing right)
9	Finish

Enemies follow any connected road; the turn tiles (3–7) are cosmetic.
