Laden von Bildern etc. #11

Closed armin-reichert closed 1 year ago

armin-reichert commented 1 year ago

Leg Deine Bilder etc. unterhalb von src/main/resources ab und verwende zum Laden nicht

grassToDirt[0] = new Image(new File("main/resources/terrain/floor/Grass_Dirt_0.png").toString(), terrainSize, terrainSize, false, false);

sondern

grassToDirt[0] = new Image( getClass().getResource("/terrain/floor/Grass_Dirt_0.png").toString(), terrainSize, terrainSize, false, false);

Beim Kompilieren/Deployment werden sie nämlich in den "classpath" (oder in ein jar File etc.) kopiert und können dann zur Laufzeit per Classloader geladen werden.

Nachdem ich alle meine Texturen so verändert hab das sie über den ResourceLoader laden: for (int i = 0; i < 4; i++) movingImagesR[i] = new Image(getClass().getResource("/player/MovingRight_" + i + ".png").toString(), playerSize, playerSize, false, false);

kriege ich nun diese Fehlermeldung da mein return value 0 ist Exception in Application start method Exception in thread "main" java.lang.RuntimeException: Exception in Application start method at com.sun.javafx.application.LauncherImpl.launchApplication1(LauncherImpl.java:901) at com.sun.javafx.application.LauncherImpl.lambda$launchApplication$2(LauncherImpl.java:196) at java.base/java.lang.Thread.run(Thread.java:1589) Caused by: java.lang.NullPointerException: Cannot invoke "java.net.URL.toString()" because the return value of "java.lang.Class.getResource(String)" is null at main.java.Player.<init>(Player.java:41) at main.java.App.start(App.java:51) at com.sun.javafx.application.LauncherImpl.lambda$launchApplication1$9(LauncherImpl.java:847) at com.sun.javafx.application.PlatformImpl.lambda$runAndWait$12(PlatformImpl.java:484) at com.sun.javafx.application.PlatformImpl.lambda$runLater$10(PlatformImpl.java:457) at java.base/java.security.AccessController.doPrivileged(AccessController.java:399) at com.sun.javafx.application.PlatformImpl.lambda$runLater$11(PlatformImpl.java:456) at com.sun.glass.ui.InvokeLaterDispatcher$Future.run(InvokeLaterDispatcher.java:96) at com.sun.glass.ui.win.WinApplication._runLoop(Native Method) at com.sun.glass.ui.win.WinApplication.lambda$runLoop$3(WinApplication.java:184) ... 1 more

Keine Panik. Liegen die Bilder unter src/main/resources/player/?
