Lightweight Java Game Library 3 Tutorial

This tutorial is for anyone who wants to get started with the new version of the Lightweight Java Game Library.
In the course of the tutorial we will use OpenGL 3.2 Core Profile for creating a small game with shaders. For older hardware there will possibly be an OpenGL 2.1 version available.

For a table of contents you can look into the wiki of this repository.

[LEGACY] LWJGL — Lightweight Java Game Library

This is the repository of the original LWJGL, which is no longer actively maintained. Unless you have released a product that uses LWJGL 2.x, you should probably be looking at LWJGL 3.

The Lightweight Java Game Library (LWJGL) is a solution aimed directly at professional and amateur Java programmers alike to enable commercial quality games to be written in Java. LWJGL provides developers access to high performance crossplatform libraries such as OpenGL (Open Graphics Library), OpenCL (Open Computing Language) and OpenAL (Open Audio Library) allowing for state of the art 3D games and 3D sound. Additionally LWJGL provides access to controllers such as Gamepads, Steering wheel and Joysticks. All in a simple and straight forward API.

LWJGL requires a JDK and Ant installed to compile, as well as your platforms native compiler to compile the JNI.

Code example for a lightweight Java gaming library

For the first solution, the library can be used entirely as recommended by the comments. However, if a smaller size is preferred, Guava’s docs specify a way to shrink JARs using ProGuard. As for the second solution, instead of using valid4j with hamcrest-matchers (which can be found on Maven Central as org.valid4j:valid4j), a more modern approach would be to utilize Guava’s Event Bus. It should be noted that it is unclear whether this will work for GWT, as it is not mentioned in the title or tags.

More struggles with 3d graphics using the lightweight java gaming library

I believe it’s not a wise decision to use a negative distance that is too close. You may want to attempt something else instead.

GLU.gluPerpective(45, 2, 0.1, 100); 

The value for 2 should represent the aspect ratio of your window, which is calculated by dividing its width by its height. In your situation, 1.333 = 800 / 600 corresponds to the correct aspect ratio.

Apart from the responses provided earlier, I figured out the solution to my query by myself. The reason for the error was because of two careless mistakes on my part. Firstly, I did not clear the screen correctly, and secondly, I did not return the method.

Advice needed for 3D objects using the Lightweight, Your using a 2d orthographic view see the following line «GL11.glOrtho (0, 800, 600, 0, 1, -1);» which clips everything to 1, -1 axis for the 3rd dimension. What you really need to be looking at is a setting up a 3d view, likely using glFrustum or gluPerspective instead of glOrtho. Although old now, you …

Lightweight Java socket library

As mentioned in the email, incorporating Jetty components could be worth considering. Jetty’s appeal lies in its compact size, self-sufficiency, and adaptable usage options.

As it appears to be unsuccessful, let me respond by stating that my personalized IO library will outperform all others.

There isn’t a universal asynchronous library that caters to all needs. While Netty and Mina come close, many projects may still require customized solutions based on pure NIO/ASYNCIO.

I believe you’re heading in the right direction. As you gain more familiarity with low-level NIO/ASYNCIO, you’ll come to recognize and effectively utilize the slightly higher-level Netty.

Lightweight java game library, After you run the applications, please look at the Run tab in IDEA, there should be the command used to run the app (for example «C:\Program Files\Java\jdk1.8.0\bin\java» -Djava.library.path=C:\lwjgl\native\windows ) and verify that the Java library path is the same as when you run it manually. –

A lightweight Java library with Preconditions?

Although the comments suggest using the entire library, there is a way to reduce the size of the JARs that is recommended in guava’s documentation — utilizing ProGuard to shrink them.

Utilizing hamcrest-matchers, available on Maven Central as org.valid4j:valid4j, is an alternative to using valid4j.

Regarding the validation of input (where recoverable exceptions are thrown):

import static org.valid4j.Validation.*; validate(argument, isValid(), otherwiseThrowing(InvalidException.class)); 

Alternatively, this can also be applied to preconditions, which are similar to assertions.

import static org.valid4j.Assertive.*; require(x, greaterThan(0)); // throws RequireViolation extends AssertionError 

• http://www.valid4j.org/
• The website address for the valid4j repository hosted on GitHub is https://github.com/helsing/valid4j.

Check out the Requirements API which I developed that is highly maintained and user-friendly. The upcoming release of version 3.0.0 has a size of 167k.

String actual = "foosball"; String expected = "ballroom"; requireThat(actual, "actual").isEqualTo(expected, "expected") 

In case your terminal lacks color support, you will receive a diff in text format instead.

Lightweight Message Bus library

The link has been corrected, all credit goes to jldupont for bringing it to our attention.

Although this question may be old, a contemporary approach would be to utilize Guava’s Event Bus. It is uncertain if this solution is suitable for GWT, given that neither the title nor the tags indicate GWT.

My RabbitMQ message container is customized to generate queue bindings automatically. Additionally, it dispatches messages received to Guava EventBus. It is an elegant and highly scalable solution.

It is simple to register the Subscribers by utilizing your DI framework. In the case of Spring, a BeanPostProcessor can be created which would automatically register the beans with @Subscribe .

Provided here is the BeanPostProcessor for Spring.

package com.snaphop.spring; import java.lang.reflect.Method; import org.springframework.beans.BeansException; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.config.BeanPostProcessor; import org.springframework.stereotype.Component; import com.google.common.eventbus.EventBus; import com.google.common.eventbus.Subscribe; @Component public class EventBusBeanPostProcessor implements BeanPostProcessor < private EventBus eventBus; @Override public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException < if (isApplicable(bean)) < eventBus.register(bean); >return bean; > @Override public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException < return bean; >protected boolean isApplicable(Object bean) < for(Method m : bean.getClass().getMethods()) < if (m.isAnnotationPresent(Subscribe.class)) return true; >return false; > @Autowired public void setEventBus(EventBus eventBus) < this.eventBus = eventBus; >> 

It should be easy to accomplish a comparable task using Guice.

For those already utilizing Spring, the ApplicationEventMulticaster interface provides a useful yet somewhat concealed feature. This interface offers a straightforward API for both publishing and subscribing to events generated by the application. Implementations utilize the TaskExecutor framework, allowing for synchronous or asynchronous functionality. Additionally, every ApplicationContext contains a publishEvent method, making it simple to configure for classes managed by Spring.

If you are a Spring user, there is no requirement for an additional utility to accomplish this task as it is already integrated within the framework.

Lightweight Java socket library, I’ve used Mina and Netty, but now I’m in the market for a lightweight library that may also be used in Android. I prefer Nio or AsyncIo over standard io implementations. Update 1. The lack of responses really makes me think I should write my own library. Right now I’m using raw NIO and its not a lot of fun. java …
