## [Unreleased]
|
||||
|
||||
## Added
|
||||
- Dokumentation erweitert.
|
||||
- Caching-Mechanismen in Klasse `util.Cache` ausgelagert.
|
||||
- `util.io.ImageLoader` und `util.io.FontLoader` verwenden `Cache`.
|
||||
- `mouseWheelMoved` Eventhandler für Mausrad.
|
||||
- `DrawingLayer.imageRotate(...)` Methoden, um Bilder um ihr Zentrum gedreht zu zeichnen.
|
||||
|
||||
## Changed
|
||||
- Die Methoden in `Validator` erwarten nun als zweiten Parameter den Namen des Parameters, der geprüft wird.
|
||||
- `DrawingLayer.image(...)` mit Größenänderung umbenannt zu `imageScale(...)`.
|
||||
- Klassen in `schule.ngb.zm.util.io` werfen nun nur eine Warnung ohne Stack-Trace, wenn die Ressource nicht gefunden werden konnte.
|
||||
|
||||
## Fixed
|
||||
- `Constants.choice(int...)` und `Constants.choice(double...)` wiederhergestellt.
|
||||
- Timing-Problem beim Aufruf von `AudioListener.playbackStopped()` in `Sound` behoben.
|
||||
|
||||
## Removed
|
||||
- `layers.Shape2DLayer` ist nur noch im Test-Paket verfügbar.
|
||||
|
||||
## Version 0.0.34
|
||||
|
||||
### Added
|
||||
- `Faker`-Klasse zur Erzeugung von Fake-Daten hinzugefügt.
|
||||
- Dokumentation unter [zeichenmaschine.xyz](https://zeichenmaschine.xyz) mit
|
||||
[MkDocs](https://www.mkdocs.org) und [Material for MkDocs](https://squidfunk.github.io/mkdocs-material/).
|
||||
- Neue `image` methoden im `DrawingLayer`.
|
||||
|
||||
### Changed
|
||||
- `FilledShape` und `StrokedShape` durch `Fillable` und `Strokeable` Interfaces ersetzt.
|
||||
- `Shape` erweitert nun `BasisDrawable` als abstrakte Grundlage.
|
||||
- `io` Klassen nutzen nun mehr der `java.nio` Funktionen.
|
||||
- Package-Struktur angepasst.
|
||||
|
||||
## Version 0.0.23
|
||||
|
||||
### 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
|
||||
- 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
|
||||
- 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.
|
||||
|
||||
### Removed
|
||||
- Beispielprojekte in [eigenes Repository](https://github.com/jneug/zeichenmaschine-examples) verschoben.
|
||||
|
||||
## Version 0.0.21
|
||||
|
||||
### Added
|
||||
- Parameter `stop_after_draw` im Konstruktor der `Zeichenmaschine` erlaubt es beim Erstellen festzulegen, ob nach dem ersten Frame die Zeichenmaschine gestoppt wird.
|
||||
- `Picture.tint(Color)` färbt ein Bild ein.
|
||||
- `Picture.flip(Options.Direction)` spiegelt ein Bild entlang einer Achse (`LEFT`/`RIGHT` für horizontal, `UP`/`DOWN` für vertikal).
|
||||
- Abstrakte Klasse `Zeichenobjekt` als einheitliche Oberklasse für Objekte in Projekten. Die Klasse erbt von `Constants` und implementiert `Drawabale` und `Updatable` mit leeren Methoden.
|
||||
- Klasse `java.util.Validator` übernimmt intern Parametervalidierung.
|
||||
- Klasse `Log` implementiert eine einfache Logging-API über `java.util.logging`.
|
||||
- Klasse `TaskRunner` führt parallele Prozesse aus.
|
||||
- `Zeichenmaschine#scheduleTask(Runnable, int)` führt eine Aufgabe nach einer Wartezeit im Gameloop aus.
|
||||
- Neue Klasse `util.ResourceStreamProvider` sucht Resourcen und öffnet `InputStream`s.
|
||||
- Abstrakte Klasse `Zeichenobjekt` als einheitliche Oberklasse für Objekte in Projekten. Die Klasse erbt von `Constants` und implementiert `Drawabale` und `Updatable` mit leeren Methoden.
|
||||
|
||||
### Changed
|
||||
- Objektvariablen der `Zeichenmaschine`, die von Unterklassen genutzt werden sollen, sind nun statisch in `Constants`. Dadurch können auch andere Klasse, die von `Constants` erben ohne Umwege auf diese Werte zugreifen (z.B. `width`/`height` der Zeichenleinwand).
|
||||
- `ImageLoader` und `FontLoader` wurden überarbeitet.
|
||||
- Nutzung von `Log`
|
||||
- Nutzung von `ResourceStreamProvider`
|
||||
- Verarbeitung von Swing `InputEvent`s in einer eigenen interne EventQueue synchron zur Framerate.
|
||||
- Objektvariablen der `Zeichenmaschine`, die von Unterklassen genutzt werden sollen, sind nun statisch in `Constants`. Dadurch können auch andere Klasse, die von `Constants` erben ohne Umwege auf diese Werte zugreifen (z.B. `width`/`height` der Zeichenleinwand).

Informatikunterricht.</h2>
|
||||
|
||||
## Projektidee
|
||||
|
||||
Die **Zeichenmaschine** ist eine für den Informatikunterricht entwickelte
|
||||
Bibliothek, die unter anderem an [Processing](https://processing.org/) angelehnt
|
||||
ist. Die Bibliothek soll einige der üblichen Anfängerschwierigkeiten mit Java
|
||||
vereinfachen und grafische Ausgaben für Schülerinnen und Schüler im Unterricht
|
||||
leichter nutzbar machen.
|
||||
|
||||
!!! warning
|
||||
|
||||
Das Projekt befindet sich noch in der Entwicklungsphase und auch wenn die
|
||||
aktuelle Version schon funktionsfähig ist und einen Großteil der angestrebten
|
||||
Funktionen enthält, ist noch keine stabile Version 1.0 erreicht. Vor allem
|
||||
am Umfang und konsistenten Design der APIs gilt es noch zu arbeiten und es
|
||||
können sich Änderungen ergeben.
|
||||
|
||||
Feedback und Vorschläge zu diesem Prozess (oder auch eine Beteiligung an der
|
||||
Entwicklung) können sehr gerne über [Github](https://github.com/jneug) oder
|
||||
[Mastodon](https://bildung.social/@ngb) an mich kommuniziert werden.
|
||||
|
||||
(Gleiches gilt für diese Webseite zum Projekt.)

## Über die Zeichenmaschine
|
||||
|
||||
Die _Zeichenmaschine_ ist aus dem Wunsch entstanden, nach einer Einführung in
|
||||
die Grundlagen der Programmiersprache Java mit Processing, einen Übergang zur
|
||||
objektorientierten Modellierung und Programmierung mit BlueJ zu leichter zu
|
||||
ermöglichen. Mit Processing kann zwar auch objektorientiert programmiert werden,
|
||||
aber mit Blick auf die Sekundarstufe II in NRW ist ein Wechsel zu einer
|
||||
generellen Programmierumgebung wie BlueJ wünschenswert.
|
||||
|
||||
Die Motivation von Processing, schnell grafische Ergebnisse der eigenen
|
||||
Programme zu sehen, sollte aber für den Übergang erhalten bleiben. So ist eine
|
||||
kleine Bibliothek mit minimalen Abhängigkeiten entstanden, die an Processing
|
||||
angelehnt einfache Schnittstellen bereitstellte, um Programmen eine grafische
|
||||
Ausgabe zu ermöglichen, ohne viel "Boilerplate" Code schreiben zu müssen.
|
||||
|
||||
Aus diesen Anfängen ist nach und nach eine umfassende Grafikbibliothek
|
||||
entstanden, die als _Zeichenmaschine_ veröffentlicht wurde.
|
||||
|
||||
### Was die Zeichenmaschine nicht ist
|
||||
|
||||
Die Bibliothek hat nicht den Anspruch, ein Konkurrent zu Processing oder
|
||||
anderen, seit Jahren etablierten und ausgereiften, Grafiksystemen zu sein. Vor
|
||||
allem ist die _Zeichenmaschine_ keine vollwertige Game Engine, die auf die
|
||||
Ausführung komplexer Spiele spezialisiert ist. Für diese Zwecke gibt es genügend
|
||||
Alternativen, von deren Nutzung gar nicht abgeraten werden soll.
|
||||
|
||||
## Aufbau der Zeichenmaschine
|
||||
|
||||
!!! info
|
||||
|
||||
In der Zeichenmaschine werden bewusst nur englischsprachige Bezeichner für
|
||||
Klassen, Methoden und Variablen verwendet. Ausnahme sind einzelne Klassen,
|
||||
die im Zusammnehang mit dem Namen der Bibliothek stehen, wie die
|
||||
Hauptklasse `Zeichenmaschine`.

# Installation
|
||||
|
||||
Um ein einfaches Projekt mit der **Zeichenmaschine** aufzusetzen ist nicht mehr
|
||||
nötig, als
|
||||
die [JAR-Datei der aktuellen Version](https://github.com/jneug/zeichenmaschine/releases/latest)
|
||||
herunterzuladen und dem *Classpath* des Projekts hinzuzufügen. Beschreibungen
|
||||
für verschiedene Entwicklungsumgebungen sind hier aufgelistet.
|
||||
|
||||
## Integration in Entwicklungsumgebungen
|
||||
|
||||
### BlueJ
|
||||
|
||||
[BlueJ](https://bluej.org) sucht an drei Orten nach Bibliotheken, die für ein
|
||||
Projekt in den Classpath aufgenommen werden:
|
||||
|
||||
- Für ein einzelnes Projekt im Projektordner im Unterordner `+libs`.
|
||||
- Im Reiter "Bibliotheken" der BlueJ-Einstellungen.
|
||||
|
||||
Hier können Programmbibliotheken hinzugefügt werden, die dann allen Projekten
|
||||
zur Verfügung stehen.
|
||||
|
||||
- Für alle Projekte und alle Nutzer dieser BlueJ-Version im
|
||||
Unterordner `userlib` des Programmordners.
|
||||
|
||||
Auf Windows-Systemen ist dieser im Order `lib` des Installationsordners von BlueJ zu finden.
|
||||
|
||||
Auf macos-Systemen muss via Rechtsklick auf die Programmdatei `BlueJ.app` über den Menüpunkt "Paketinhalt zeigen" in den Ordner `Contents/Resources/Java/` navigiert werden.

# Schnellstart mit der Zeichenmaschine
|
||||
|
||||
Um die **Zeichenmaschine** in einem Projekt zu nutzen ist nicht mehr nötig, als
|
||||
die [JAR-Datei der aktuellen Version](https://github.com/jneug/zeichenmaschine/release/latest)
|
||||
herunterzuladen und
|
||||
dem [Classpath](https://www.delftstack.com/de/howto/java/java-classpath-/)
|
||||
hinzuzufügen. Eine Beschreibung für verschiedene Entwicklungsumgebungen findet
|
||||
sich im Abschnitt [Installation](installation.md).
|
||||
|
||||
## Die Basisklasse
|
||||
|
||||
Eine _Zeichenmaschine_ wird immer als Unterklasse von {{ javadoc_link("
|
||||
schule.ngb.zm.Zeichenmaschine") }} erstellt.
|
||||
|
||||
```java
|
||||
public class Shapes extends Zeichenmaschine {
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
Die gezeigte Klasse ist schon eine lauffähige Zeichenmaschine und kann gestartet
|
||||
werden.
|
||||
|
||||
!!! note "main Methode"
|
||||
|
||||
Bei einigen Entwicklungsumgebungen muss noch eine `main` Methode erstellt
|
||||
werden, um die Zeichenmaschine zu starten:
|
||||
|
||||
```java
|
||||
public static void main(String[] args) {
|
||||
new Shapes();
|
||||
}
|
||||
```
|
||||
|
||||
Es öffnet sich ein Zeichenfenster in einer vordefinierten Größe. Um die
|
||||
Abmessungen und den Titel des Fensters zu ändern, legen wir einen Konstruktor
|
||||
an.
|
||||
|
||||
???+ example "Quelltext"
|
||||
|
||||
```java
|
||||
public class Shapes extends Zeichenmaschine {
|
||||
|
||||
public Shapes() {
|
||||
super(800, 800, "Shapes");
|
||||
}
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
Starten wir das Projekt, wird eine Zeichenfläche in der Größe 800-mal-800 Pixel
|
||||
erstellt und in einem Fenster mit dem Titel „Shapes“ angezeigt.
|
||||
|
||||
<figure markdown>
|
||||
{ width=400 }
|
||||
</figure>
|
||||
|
||||
### Formen zeichnen
|
||||
|
||||
Eine Zeichenmaschine hat verschiedene Möglichkeiten Inhalte in das
|
||||
Zeichenfenster zu zeichnen. Um ein einfaches statisches Bild zu erzeugen,
|
||||
überschreiben wir die {{ jdl("schule.ngb.zm.Zeichenmaschine", "draw()",
|
||||
c=False) }} Methode.
|
||||
|
||||
???+ example "Quelltext"
|
||||
|
||||
```java
|
||||
public class Shapes extends Zeichenmaschine {
|
||||
|
||||
public Shapes() {
|
||||
super(800, 800, "Shapes");
|
||||
}
|
||||
|
||||
@Override
|
||||
public void draw() {
|
||||
background.setColor(BLUE);
|
||||
|
||||
drawing.setFillColor(255, 223, 34);
|
||||
drawing.noStroke();
|
||||
drawing.circle(400, 400, 100);
|
||||
}
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
Wir sehen einen gelben Kreis (ohne Konturlinie) auf einem blauen Hintergrund.
|
||||
|
||||
<figure markdown>
|
||||
{ width=400 }
|
||||
</figure>
|
||||
|
||||
### Vorbereitung der Zeichenfläche
|
||||
|
||||
Im Beispiel oben setzen wir die Hintergrundfarbe auf Blau, die Füllfarbe auf
|
||||
Gelb und deaktivieren die Konturlinie. Wenn diese Einstellungen für alle
|
||||
Zeichenobjekte gleich bleiben, können wir sie statt in `draw()` auch in die {{
|
||||
jdl('Zeichenmaschine', 'setup()', c=False) }} Methode schreiben. Diese bereitet
|
||||
die Zeichenfläche vor dem ersten Zeichnen vor.
|
||||
|
||||
???+ example "Quelltext"
|
||||
|
||||
```java
|
||||
public class Shapes extends Zeichenmaschine {
|
||||
|
||||
public Shapes() {
|
||||
super(800, 800, "Shapes");
|
||||
}
|
||||
|
||||
@Override
|
||||
public void setup() {
|
||||
background.setColor(BLUE);
|
||||
|
||||
drawing.setFillColor(255, 223, 34);
|
||||
drawing.noStroke();
|
||||
}
|
||||
|
||||
@Override
|
||||
public void draw() {
|
||||
for( int i = 0; i < 10; i++ ) {
|
||||
drawing.circle(
|
||||
random(0, canvasWidth),
|
||||
random(0, canvasHeight),
|
||||
random(50, 200)
|
||||
);
|
||||
}
|
||||
}
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
Im Beispiel setzen wir nun die Grundeinstellungen in der `setup()` Methode. In
|
||||
`draw()` werden zehn gelbe Kreise an Zufallskoordinaten gezeichnet.
|
||||
|
||||
<figure markdown>
|
||||
{ width=400 }
|
||||
</figure>
|
||||
|
||||
!!! tip ""
|
||||
|
||||
Mit {{ jdm("Constants", "canvasWidth") }} und
|
||||
{{ jdm("Constants", "canvasHeight") }} kannst du in der Zeichenmaschine
|
||||
auf die aktuelle Größe der Zeichenfläche zugreifen.
|
||||
{{ jdm("Constants", "random(int,int)") }} erzeugt eine Zufallszahl
|
||||
innerhalb der angegebenen Grenzen.
|
||||
|
||||
## Interaktionen mit der Maus: Whack-a-mole
|
||||
|
||||
Mit der Zeichenmaschine lassen sich Interaktionen mit der Maus leicht umsetzen.
|
||||
Wir wollen das Beispielprogramm zu einem
|
||||
[Whac-A-Mole](https://de.wikipedia.org/wiki/Whac-A-Mole) Spiel erweitern.
|
||||
|
||||
Auf der Zeichenfläche wird nur noch ein gelber Kreis an einer zufälligen Stelle
|
||||
angezeigt. Sobald die Spieler:in auf den Kreis klickt, soll dieser an eine neue
|
||||
Position springen.
|
||||
|
||||
Damit wir den Kreis an eine neue Position springen lassen können, müssen wir
|
||||
zufällige `x`- und `y`-Koordinaten generieren. Dazu erstellen wir zunächst zwei
|
||||
_Objektvariablen_ für die Koordinaten, die in der `setup()` Methode mit
|
||||
zufälligen Werte initialisiert werden. Diese benutzen wir, um die `draw
|
||||
()` Methode anzupassen.
|
||||
|
||||
??? example "Quelltext"
|
||||
|
||||
```Java
|
||||
public class Shapes extends Zeichenmaschine {
|
||||
|
||||
private int moleRadius = 20;
|
||||
|
||||
private int moleX;
|
||||
|
||||
private int moleY;
|
||||
|
||||
public Shapes() {
|
||||
super(800, 800, "Shapes");
|
||||
}
|
||||
|
||||
@Override
|
||||
public void setup() {
|
||||
background.setColor(BLUE);
|
||||
|
||||
drawing.setFillColor(255, 223, 34);
|
||||
drawing.noStroke();
|
||||
|
||||
moleX = random(50, canvasWidth - 50);
|
||||
moleY = random(50, canvasHeight - 50);
|
||||
}
|
||||
|
||||
@Override
|
||||
public void draw() {
|
||||
drawing.clear();
|
||||
drawing.circle(moleX, moleY, moleRadius);
|
||||
}
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
<figure markdown>
|
||||
{ width=600 }
|
||||
</figure>
|
||||
|
||||
Als Nächstes prüfen wir bei jedem Mausklick, ob die Mauskoordinaten innerhalb
|
||||
des gelben Kreises (des Maulwurfs) liegen. Die Mauskoordinaten sind jederzeit
|
||||
über die Variablen `mouseX` und `mouseY` abrufbar. Um zu prüfen, ob diese
|
||||
Koordinaten innerhalb des Kreises liegen, vergleichen wir den Abstand zwischen
|
||||
Kreismittelpunkt `(moleX, moleY)` und den Mauskoordinaten
|
||||
`(mouseX, mouseY)` mit dem Radius des Kreises (im Bild grün). Ist die Entfernung
|
||||
kleiner als der Radius (blauer Kreis), wurde innerhalb des Kreises geklickt.
|
||||
Sonst außerhalb (roter Kreis).
|
||||
|
||||
<figure markdown>
|
||||
{ width=400 }
|
||||
</figure>
|
||||
|
||||
Den Abstand vom Mittelpunkt zur Maus lässt sich mithilfe des Satzes des
|
||||
Pythagoras leicht selber berechnen. Die Zeichenmaschine kann uns diese Arbeit
|
||||
aber auch abnehmen und stellt eine Methode dafür bereit
|
||||
({{ jdm("Constants", "distance(double,double,double,double)") }}).
|
||||
|
||||
Um auf einen Mausklick zu reagieren, ergänzen wir die
|
||||
{{ jdm("Zeichenmaschine", "mouseClicked()") }} Methode:
|
||||
|
||||
```java
|
||||
@Override
|
||||
public void mouseClicked() {
|
||||
if( distance(moleX, moleY, mouseX, mouseY) < moleRadius ) {
|
||||
moleX = random(50, canvasWidth - 50);
|
||||
moleY = random(50, canvasHeight - 50);
|
||||
redraw();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
```Java
|
||||

|
||||
|
||||
private int moleRadius = 20;

|
||||
|

|

|
||||
moleY = random(50, canvasHeight - 50);

}
|

|
||||
@Override
|
||||
public void draw() {

|
||||

|
||||
}
|
||||
|
||||
@Override
|
||||
public void mouseClicked() {
|
||||
if( distance(moleX, moleY, mouseX, mouseY) < moleRadius ) {
|
||||

!!! warning ""
|
||||
|
||||
Der Aufruf von {{ jdm("Zeichenmaschine", "redraw()") }} zeichnet
|
||||
die Zeichenfläche neu, indem die `draw()` Methode erneut aufgerufen wird.
|
||||
Du solltest `draw()` niemals direkt aufrufen.
|
||||
|
||||
Nun springt der Kreis an eine andere Stelle, wenn er direkt mit der Maus
|
||||
angeklickt wird.

## Ein paar Details zur Zeichenmaschine
|
||||
|
||||
Die _Zeichenmaschine_ wurde stark von der kreativen Programmierumgebung
|
||||
[Processing](https://processing.org) inspiriert. Wenn du Processing schon
|
||||
kennst, dann werden dir einige der Konzepte der _Zeichenmaschine_ schon bekannt
|
||||
vorkommen.
|
||||
|
||||
### Farben
|
||||
|
||||
Farben können auf verschiedene Weisen angegeben werden. Unser Beispiel nutzt
|
||||
bisher zwei Arten:
|
||||
|
||||
1. Die einfachste Möglichkeit sind die _Farbkonstanten_
|
||||
wie {{ jdm('Constants', 'BLUE') }} oder {{ jdm('Constants', 'RED') }}. Im
|
||||
Beispiel setzen wir den Hintergrund auf die Farbe `BLUE`.
|
||||
2. Farben werden häufig im RGB-Farbraum definiert. Dazu wird jeweils der Rot-,
|
||||
Grün- und Blauanteil der Farbe als Wert zwischen 0 und 255 angegeben. Im
|
||||
Beispiel setzen wir die Farbe der Kreise auf `255, 223, 34`, also viel Rot
|
||||
und Grün und nur ein wenig Blau.
|
||||
|
||||
### Ebenen
|
||||
|
||||
Die Zeichenfläche besteht aus einzelnen {{ jdl("Layer", title="Ebenen") }}, die
|
||||
auf übereinander liegen. Bis auf die unterste Ebene sind die Ebenen zunächst
|
||||
durchsichtig, wodurch die Zeichnungen unterer Ebenen durchscheinen.
|
||||
|
||||
<figure markdown>
|
||||
{ width=600 }
|
||||
</figure>
|
||||
|
||||
Eine _Zeichenmaschine_ besitzt zu Beginn drei Ebenen:
|
||||
|
||||
1. Die unterste Ebene ist ein {{ jdc("layers.ColorLayer") }}, die nur aus einer
|
||||
Farbe (oder einem Farbverlauf) besteht und keine durchsichtigen Bereiche
|
||||
besitzt. Im Beispiel setzen wir diese Ebene auf die Farbe `BLUE`.
|
||||
2. Die nächste Ebene ist ein {{ jdc("layers.DrawingLayer") }}, auf die wir
|
||||
unsere Formen zeichnen können. Die Ebene ist zunächst komplett durchsichtig.
|
||||
3. Die oberste Ebene ist ein {{ jdc("layers.ShapesLayer") }}, die zur
|
||||
Darstellung von Form-Objekten der Klasse {{ jdc("shapes.Shape") }} genutzt
|
||||
werden kann.
|
||||
|
||||
Du kannst einer Zeichenfläche aber auch beliebige neue oder selbst programmierte
|
||||
Ebenen hinzufügen.
|
||||
|
||||
### Ablauf
|
||||
|
||||
Die _Zeichenmaschine_ ruft nach dem Start die Methoden in einem festen Ablauf
|
||||
auf.
|
||||
|
||||
<figure markdown>
|
||||
{ width=500 }
|
||||
</figure>
|
||||
|
||||
Erstellst Du eine _Zeichenmaschine_ (beziehungsweise ein Objekt einer
|
||||
Unterklasse), dann wird zuerst die {{ jdm('Zeichenmaschine', 'setup()') }}
|
||||
Methode ausgeführt. Danach folgt einmalig die
|
||||
{{ jdm('Zeichenmaschine', 'draw()') }} Methode und dann endet das Hauptprogramm.
|
||||
|
||||
Die Eingaben der Maus werden in einem parallelen Ablauf (einem _Thread_)
|
||||
abgefangen und daraufhin die {{ jdm('Zeichenmaschine', 'mouseClicked()') }}
|
||||
Methode aufgerufen. In unserem Programm prüfen wir, ob mit der Maus
|
||||
innerhalb des Kreises geklickt wurde und rufen dann
|
||||
{{ jdm('Zeichenmaschine', 'redraw()') }} auf, woraufhin ein weiteres Mal
|
||||
`draw()` ausgeführt wird.
|
||||
|
||||
In _Processing_ wird dies der "statische" Modus genannt, weil das Programm nur
|
||||
einmal abläuft und dann stoppt. "Statisch" trifft es nicht ganz, da das Programm
|
||||
ja zum Beispiel durch Mauseingaben auch verändert werden kann. Wichtig ist aber,
|
||||
dass mit `redraw()` die Zeichenfläche manuell neu gezeichnet werden muss, damit
|
||||
sich der Inhalt ändert.
|
||||
|
||||
## Dynamische Programme
|
||||
|
||||
Wir wollen unser kleines Spiel dynamischer machen, indem die Kreise nur drei
|
||||
Sekunden angezeigt werden und dann von selbst an einen neuen Ort springen.
|
||||
Schafft man es, den Kreis in dieser Zeit anzuklicken, bekommt man einen Punkt.
|
||||
|
||||
Als zusätzliche Herausforderung lassen wir jeden Kreis in den drei Sekunden
|
||||
immer kleiner werden.
|
||||
|
||||
### Die Update-Draw-Schleifen
|
||||
|
||||
{ width=200 align=right }
|
||||
|
||||
Bisher hat die _Zeichenmaschine_ einmalig `draw()` aufgerufen und dann nur noch
|
||||
auf Benutzereingaben mit der Maus reagiert. Nun wollen wir das gezeichnete Bild
|
||||
aber laufend anpassen. Der Kreis soll schrumpfen und nach 3 Sekunden
|
||||
verschwinden.
|
||||
|
||||
Dazu ergänzen wir ein {{ jdl('Zeichenmaschine', 'update(double)', c=False) }}
|
||||
Methode in unserem Programm. Nun schaltet die _Zeichenmaschine_ in einen
|
||||
dynamischen Modus und startet die _Update-Draw-Schleife_. Das beduetet, nach
|
||||
Aufruf von `setup()` wird fortlaufend immer wieder zuerst `update()` und dann
|
||||
`draw()` aufgerufen.
|
||||
|
||||
Jeder Aufruf der `draw()` Methode zeichnet nun die Zeichenfläche neu. Jedes
|
||||
Bild, das gezeichnet wird (auch, wenn es genauso aussieht, wie das davor), nennt
|
||||
man ein _Frame_. Von Videospielen kennst Du vielleicht schon den Begriff "
|
||||
_Frames per second_" (Fps, dt. Bilder pro Sekunde). Er bedeutet, wie oft das
|
||||
Spiel neue Frames zeichnet, oder in der _Zeichenmaschine_, wie oft `draw()` pro
|
||||
Sekunde aufgerufen wird. Normalerweise passiert dies genau 60-mal pro Sekunde.
|
||||
|
||||
### Lebenszeit eines Kreises
|
||||
|
||||
Jeder Kreis soll drei Sekunden zu sehen sein. Daher fügen wir eine neue
|
||||
Objektvariable namens `moleTime` ein, die zunächst auf Drei steht. Da wir auch
|
||||
Bruchteile von Sekunden abziehen wollen, wählen wir als Datentyp `double`:
|
||||
|
||||
```Java
|
||||
private double moleTime=3.0;
|
||||
```
|
||||
|
||||
Der Parameter `delta` der `update()` Methode ist der Zeitraum in Sekunden seit
|
||||
dem letzten Frame. Subtrahieren wir diesen Wert bei jedem Frame von `moleTime`,
|
||||
wird der Wert immer kleiner. Dann müssen wir nur noch prüfen, ob er kleiner Null
|
||||
ist und in dem Fall den Kreis auf eine neue Position springen lassen.
|
||||
|
||||
Die Größe des Kreises passen wir so an, dass der Anteil der vergangenen Zeit die
|
||||
Größe des Kreises bestimmt:
|
||||
|
||||
```Java
|
||||
drawing.circle(moleX,moleY,moleRadius*(moleTime/3.0));
|
||||
```
|
||||
|
||||

||||

|

|
||||
Der Maulwurf muss mittlerweile an drei verschiedenen Stellen im Programm
|
||||
auf eine zufällige Position gesetzt werden (am Anfang, wenn er angeklickt
|
||||
wurde und wenn die drei Sekunden abgelaufen sind). Daher wurde das Versetzen
|
||||
in eine eigene Methode `randomizeMole()` ausgelagert.
|
||||
|
||||
### Punktezähler
|
||||
|
||||
Zum Schluss wollen wir noch bei jedem Treffer mit der Maus die Punkte zählen und
|
||||
als Text auf die Zeichenfläche schreiben.
|
||||
|
||||
Dazu ergänzen wir eine weitere Objektvariable `score`, die in `mouseClicked()`
|
||||
erhöht wird, falls der Kreis getroffen wurde.
|
||||
|
||||
Um den Punktestand anzuzeigen ergänzen wir in `draw()` einen Aufruf von
|
||||
{{ jdl('layers.DrawingLayer', 'text(java.lang.String,double,double,schule.ngb.zm.Options.Direction)') }}
|
||||
mit dem Inhalt von `score` und den Koordinaten, an denen der Text gezeigt
|
||||
werden soll.
|
||||
Die Zeichenebene zeichnet im Moment alle Formen und Text ausgehend vom Zentrum
|
||||
der Form. Damit der Text 10 Pixel vom Rand entfernt links oben angezeigt wird,
|
||||
können wir der Text Methode (und allen anderen, die etwas zeichnen) eine {{
|
||||
jdl('Options.Direction', title='Richtung') }} übergeben, die festlegt, von
|
||||
welchem Ausgangspunkt (oder _Ankerpunkt_) die Form gezeichnet werden soll.
|
||||
|
||||
```Java
|
||||
drawing.setFillColor(BLACK);
|
||||
drawing.text("Punkte: "+score,10,10,NORTHWEST);
|
||||
```

||||

## Wie es weitergehen kann
|
||||
|
||||
In diesem Schnellstart-Tutorial hast du die Grundlagen der _Zeichenmaschine_
|
||||
gelernt. Um weiterzumachen, kannst du versuchen, das Whack-a-mole Spiel um diese
|
||||
Funktionen zu erweitern:
|
||||
|
||||
- Mehrere "Maulwürfe" gleichzeitig.
|
||||
- Unterschiedliche Zeiten pro Maulwurf.
|
||||
|
||||
Wenn du mehr über die Möglichkeiten lernen möchtest, die dir die
|
||||
_Zeichenmaschine_ bereitstellt, kannst du dir die weiteren Tutorials in dieser
|
||||
Dokumentation ansehen. Ein guter Startpunkt ist das
|
||||
[Aquarium](tutorials/aquarium/aquarium1.md).
|
||||
|
||||
Viele verschiedene Beispiele, ohne detailliertes Tutorial, findest du in der
|
||||
Kategorie Beispiele und auf GitHub im Repository

# Tutorial: Aquarium
|
||||
|
||||
In diesem Tutorial wollen wir mithilfe der _Zeichenmaschine_ ein (bonbonbuntes)
|
||||
interaktives Aquarium entwickeln. Dabei werden wir in verschiedenen Ausbaustufen
|
||||
zunächst das System Modellieren und dann implementieren.
|
||||
|
||||
!!! info "Mein bonbonbuntes Aquarium"
|
||||
|
||||
Das Projekt [Mein bonbonbuntes Aquarium](http://blog.schockwellenreiter.de/2021/02/2021021201.html)
|
||||
stammt ursprünglich aus dem Blog [Schockwellenreiter](http://blog.schockwellenreiter.de)
|
||||
von [Jörg Kantel](http://cognitiones.kantel-chaos-team.de/cv.html).
|
||||
|
||||
Das Endprodukt soll folgendes umfassen:
|
||||
|
||||
- Darstellung eines hübschen Aquariums mit Fischen, die hin und her schwimmen.
|
||||
- Zur Darstellung wollen wir wie im Original die Sprites aus dem [Fish Pack von Kenny.nl](https://www.kenney.nl/assets/fish-pack) nutzen.
|
||||
- Das Aquarium soll durch passende Geräusche untermalt werden.
|
||||
- Bei einem Klick in das Aquarium soll ein zufälliger Fisch erscheinen.
|
||||
- Bei einem Druck auf die Leertaste soll ein Hai durch das Aquarium schwimmen und alle Fische auf seinem Weg auffressen.
