guacamole

A small collection of some common and very basic utilities for libGDX games, which is used in libgdx-screenmanager and pancake.

Core

dependencies {
    implementation 'com.github.crykn.guacamole:core:$guacamoleVersion'
}

• @Beta: an annotation to denote APIs that may be subject to changes in future releases
• BooleanConsumer, FloatConsumer, ShortConsumer, ICallback
• ClassUtils: contains utilities for dealing with classes
• ConcatenatedIterator: this class aggregates multiple iterators into one
• DaemonThreadFactory: a ThreadFactory creating daemon threads
• Exceptions: #throwAsRuntimeException(Exception), #getStackTraceAsString(Exception)
• @GwtIncompatible: indicates that an API is not compatible with GWT and thus shouldn't be compiled for it
• IntRange
• MoreObjects: contains helper functions for dealing with objects which are not already included in Java's Objects class
• @Nullable: the @Nullable annotation from JSpecify is provided as a transitive dependency
• Pair, Triple, IntPair & IntTriple implementations (immutable)
• Preconditions: has methods like #checkArgument(boolean, String), #checkState(boolean, String) & #checkNotNull(Object, String); is slimmer than the commonly known class from guava
• StopWatch
• ThreadHandler: a class to easily offload simple, time-consuming tasks onto threads

Core project:

dependencies {
    implementation "com.github.crykn.guacamole:gdx:$guacamoleVersion" // guacamole-core is included
}

Html project:

dependencies {
    implementation "com.github.crykn.guacamole:gdx:$guacamoleVersion" // guacamole-core is included
    
    implementation "com.github.crykn.guacamole:core:$guacamoleVersion:sources"
    implementation "com.github.crykn.guacamole:gdx:$guacamoleVersion:sources"
    implementation "com.github.crykn.guacamole:gdx-gwt:$guacamoleVersion"
    implementation "com.github.crykn.guacamole:gdx-gwt:$guacamoleVersion:sources"
}

Module file (GdxDefinition.gwt.xml):

<inherits name="guacamole_gdx_gwt" />

What is added:

• DefaultInputProcessor: an InputProcessor providing default methods to reduce boilerplate code; is an interface alternative to InputAdapter
• DisposablePool, Vector2Pool & Vector3Pool
• FPSCounter
• IntVector2: a vector for integer values
• Logger & LoggerService: supports formatting; is super-sourced on GWT via formic; use LoggerService.getLogger(MyGdxGame.class) to obtain a logger; calling, for instance, logger.error("something went %s!", "wrong") leads to the following console output: [ERROR] [c.b.g.m.MyGdxGame]: something went wrong!
• NestableFrameBuffer: a nestable framebuffer implementation, see here for details
• QuadMeshGenerator: allows easily creating different quads; is useful when applying shaders
• ReflectionUtils: utility methods for dealing with libGDX's reflection
• ShaderCompatibilityHelper: Allows converting GLSL shader code from version 120 to 150
• ShaderProgramFactory & ShaderPreconditions: Adds methods to easily create & compile a shader (#fromString(String, String)); automatically throws exceptions when the compilation fails; prepends can be ignored
• Text asset type

gdx-desktop

Desktop project:

dependencies {
    implementation "com.github.crykn.guacamole:gdx:$guacamoleVersion" // guacamole-core is included
    
    implementation "com.github.crykn.guacamole:gdx-desktop:$guacamoleVersion"
}

What is added:

• StartOnFirstThreadHelper: Starts a new JVM if the current one was not started with the -XstartOnFirstThread argument on macOS; this is only needed for the LWJGL 3 backend!
