Laden von Texturen nicht möglich

[maxf]

Hallo,

ich habe folgendes problem: Wenn ich in Eclipse(V3.1) versuche eine Textuer zu laden,
erhalte ich folgende Fehlermeldung: The method setTexture(Texture)
in the type Appearance is not applicable for the arguments (Texture)
Code:

		add("Center", c);
		u = new SimpleUniverse(c);
		u.getViewingPlatform().setNominalViewingTransform();
		u.addBranchGraph(createSceneGraph());
	}

	public void destroy(){
		u.cleanup();
	}

	public static void main(String[] args) {
		new MainFrame(new Game(), 400, 400);
	}
}

Bitte helft mir!

Irgendwie ist deine TexttureLoader.INSTANCE.getTexture-Konstruktion auch etwas merkwürdig, ich hab' mal das hier gefunden, kannst's ja mal ausprobieren:

        earthAppear.setTexture( new TextureLoader(TEXTURE_FNAME, this).getTexture());

Finktioniert auch nicht, Fehlermeldung:
The constructor TextureLoader(String, Game) is undefined.

Ich habs nochmal anders probiert, funktioniert auch nicht:

SphereAppearance.setTexture( new TextureLoader("texturen/Wand.jpg", new Component()).getTexture());

Fehlermeldung:
The constructor TextureLoader(String, Component) is undefined.

Versuch mal null, statt this oder new Component()

 

[maxf]

Funktioniert leider auch nicht. :cry:

hgr....das gibt's doch garnicht.

Welche Versionen hast du überhaupt, kann es sein, dass das nur an Eclipse liegt, oder kommen die Fehler schon direkt vom Kompiler?

Hier, kompilier mal den Code, dann sehen wir weiter:

Das ist zwar nicht so sauber programmiert, hab' aber gerade nix besseres, in den Ordner Texturen packst du dann noch eine Datei mit dem Namen "test.jpg"/Inhalt ist ja egal/ und dann schau erstmal ob das geht....

 

[maxf]

Ich verwende Win2k Server, Eclipse 3.1.1, JRE/JDK 1.5_5, Java 3D API 1.3.1

P.S.: Es läuft immer noch nicht.

 

[MPW]

Auch mein Code nicht?
Obwohl eine Texturedatei da ist,

was gibt's denn als Exception,
kompilieren lässt sich der Code ja, da ich ihn getestet hab!

 

[maxf]

Ich habe rausgefunden, warums nicht läuft:
Es waren Zwei gleichnemige Klassen im classpath.
Diese waren aber für JGOL(oder wie auch immer).
Trozdem vielen Dank!

 

[MPW]

Was ist denn das für eine Entwicklungsumgebung, wenn die das nicht merkt, weil der Compiler merkt ja sowas an, die IDE muss sowas eigentlich weitergeben....
