|
||||
|
||||
## [Unreleased]
|
||||
|
||||
### Added
|
||||
- System für EventListener.
|
||||
- `AudioListener` und `AnimationListener` als erste Anwendungsfälle.
|
||||
- Pakete für Animationen und Maschinelles-Lernen.
|
||||
- Farbverläufe als Füllung.
|
||||
|
||||
### Changed
|
||||
- `update(double)` und `draw()` werden nun in einem eigenen Thread aufgerufen.
|
||||
- Die Standardwerte in `Constants` wurden mit dem Prefix `DEFAULT_` benannt (vorher `STD_`).
|
||||
- Die Standardwerte sind nun nicht mehr `final` und können vom Nutzer manuell gesetzt werden.
|
||||
|
||||
## Version 0.0.22
|
||||
|
||||
### Added
|
||||
## Added
|
||||
- Interface `Audio` extrahiert, mit Basisfunktionen von `Sound` und `Music`.
|
||||
- Klasse `Mixer` steuert mehrere Audio-Objekte gleichzeitig.
|
||||
- Klasse `tasks.RateLimitedTask`, `tasks.FramerateLimitedTask`, `tasks.FrameSynchronizedTask` und `tasks.DelayedTask`.
|
||||
|
||||
### Changed
|
||||
## Changed
|
||||
- Neue Package-Struktur:
|
||||
- `schule.ngb.zm.media` für Audio-Klassen (und ggf. zukünftig Video).
|
||||
- `schule.ngb.zm.util.tasks` für alles Rund um Parallelität.
|
||||
- `Zeichenthread` und `TaskRunner` setzen die Namen der Threads für besseres Debugging.
|
||||
- `schule.ngb.zm.tasks` für alles Rund um Parallelität.
|
||||
|
||||
### Removed
|
||||
- Beispielprojekte in [eigenes Repository](https://github.com/jneug/zeichenmaschine-examples) verschoben.

# Gradle start up script for POSIX generated by Gradle.
|
||||
#
|
||||
# Important for running:
|
||||
#
|
||||
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
|
||||
# noncompliant, but you have some other compliant shell such as ksh or
|
||||
# bash, then to run this script, type that shell name before the whole
|
||||
# command line, like:
|
||||
#
|
||||
# ksh Gradle
|
||||
#
|
||||
# Busybox and similar reduced shells will NOT work, because this script
|
||||
# requires all of these POSIX shell features:
|
||||
# * functions;
|
||||
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
|
||||
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
|
||||
# * compound commands having a testable exit status, especially «case»;
|
||||
# * various built-in commands including «command», «set», and «ulimit».
|
||||
#
|
||||
# Important for patching:
|
||||
#
|
||||
# (2) This script targets any POSIX shell, so it avoids extensions provided
|
||||
# by Bash, Ksh, etc; in particular arrays are avoided.
|
||||
#
|
||||
# The "traditional" practice of packing multiple parameters into a
|
||||
# space-separated string is a well documented source of bugs and security
|
||||
# problems, so this is (mostly) avoided, by progressively accumulating
|
||||
# options in "$@", and eventually passing that to Java.
|
||||
#
|
||||
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
|
||||
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
|
||||
# see the in-line comments for details.
|
||||
#
|
||||
# There are tweaks for specific operating systems such as AIX, CygWin,
|
||||
# Darwin, MinGW, and NonStop.
|
||||
#
|
||||
# (3) This script is generated from the Groovy template
|
||||
# https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
|
||||
