JavaCPP Presets for LiquidFun

^{Build status for all platforms: Commercial support:}

Introduction

This directory contains the JavaCPP Presets module for:

• LiquidFun https://github.com/google/liquidfun

Please refer to the parent README.md file for more detailed information about the JavaCPP Presets.

Documentation

Java API documentation is available here:

• http://bytedeco.org/javacpp-presets/liquidfun/apidocs/

Sample Usage

Here is a simple example of LiquidFun ported to Java.

We can use Maven 3 to download and install automatically all the class files as well as the native binaries. To run this sample code, after creating the pom.xml and Example.java source files below, simply execute on the command line:

 $ mvn compile exec:java

The pom.xml build file

<project>
    <modelVersion>4.0.0</modelVersion>
    <groupId>org.bytedeco.liquidfun</groupId>
    <artifactId>example</artifactId>
    <version>1.5.8</version>
    <properties>
        <exec.mainClass>Example</exec.mainClass>
    </properties>
    <dependencies>
        <dependency>
            <groupId>org.bytedeco</groupId>
            <artifactId>liquidfun-platform</artifactId>
            <version>master-1.5.8</version>
        </dependency>
    </dependencies>
    <build>
        <sourceDirectory>.</sourceDirectory>
    </build>
</project>

The Example.java source file

import org.bytedeco.javacpp.*;
import org.bytedeco.liquidfun.*;
import static org.bytedeco.liquidfun.global.liquidfun.*;

public class Example {
  public static void main(String[] args) {
    b2World w = new b2World(0.0f, -10.0f);
    b2BodyDef bd = new b2BodyDef();
    bd.type(b2_dynamicBody);
    bd.SetPosition(1.0f, 5.0f);
    b2CircleShape c = new b2CircleShape();
    c.m_radius(2.0f);
    b2FixtureDef fd = new b2FixtureDef();
    fd.shape(c).density(1.0f);
    b2Body b = w.CreateBody(bd);
    b.CreateFixture(fd);
    for (int i = 1; i <= 5; i++) {
      System.out.println(i + ": ball at " + b.GetPositionX() + "," + b.GetPositionY());
      w.Step(0.1f, 2, 8);
    }
    System.exit(0);
  }
