I have a game over class but when i try to put it into the world i get an error.
the code in the game over class is
java.lang.IllegalArgumentException: java.io.FileNotFoundException: Could not find file: heath0 at greenfoot.GreenfootImage.loadFile(GreenfootImage.java:293) at greenfoot.GreenfootImage.<init>(GreenfootImage.java:109) at HeathBar.<init>(HeathBar.java:37) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:525) at greenfoot.core.Simulation.newInstance(Simulation.java:578) at greenfoot.localdebugger.LocalDebugger$QueuedInstantiation.run(LocalDebugger.java:155) at greenfoot.core.Simulation.runQueuedTasks(Simulation.java:465) at greenfoot.core.Simulation.maybePause(Simulation.java:279) at greenfoot.core.Simulation.runContent(Simulation.java:210) at greenfoot.core.Simulation.run(Simulation.java:203) Caused by: java.io.FileNotFoundException: Could not find file: heath0 at greenfoot.util.GreenfootUtil.getURL(GreenfootUtil.java:534) at greenfoot.GreenfootImage.loadFile(GreenfootImage.java:290) ... 12 more java.lang.IllegalArgumentException: Filename 'heath2.png' has the wrong case.
