An easy, light, native game engine running on JVM.

Why easy? 为什么简单易用？

一个简单的Flappy bird 仅用了65行代码。 使用Kotlin写就，并支持Java, JRuby, Groovy, Scala等语言。 A flappy bird game is in 65 lines of code only.
Written in Kotlin, also work on Java, JRuby, Groovy and Scala.

Why light? 为什么轻量？

Kotlin运行时库仅用736KB（使用Kotlin开发游戏可以在游戏集成而不必引擎附带），引擎也仅仅略大于800KB。
未来将会加入的MP3支持可能会占用200KB。

Kotlin runtime is 736KB in size (if not using Kotlin to build games), and the engine JAR file size is just a bit above 800KB.
MP3 format support (in the future) will take 200KB.

Why native? 为什么原生？

This engine is completely platform-independent: no JNIs, no native methods, everything is written by myself in pure Kotlin.
And this is what a JVM app should be exactly.

Before you build

clone (clone https://github.com/icela/FriceEngine.git) and open with IntelliJ IDEA(please install Kotlin, Groovy, or Ruby plugin first).

Build

Currently under construction. Maybe you know how to build your own apps.

Usage

Supported

Languages

• Kotlin (Native)
• Java
• Groovy
• JRuby
• Scala (Not tested)

Functions

• Game Objects (from image or shape, image from file or web)
• Life cycle
• Collision detecting
• Audio playing (*.wav only)
• Dialogs
• Cursor overriding
• Clock system
• Animations (frame, move, scale, accelerate, etc.)
• A simple key-value database
• Screen cut
• Buttons
• Particle effects
• Easy time controlling
• Language extensions(for Kotlin only)

Basics

FriceEngine is based on the life cycle mode.
To build games based on frice engine, follow these steps:

1. Import the jar in the latest release to your project.
2. Create a class extends Game in org.frice.game package.
3. Implement the abstract methods, just understand them by name.
4. call the empty constructor in the public static void main.
