I want to quit the current world and load another world that is already saved.

I want to unload the current world and start another. The loadWorld() method's javadocs says it will unloads the world first. Is there a better way to implement this?

I am trying to use loadWorld() method from net.minecraft.client.Minecraft. However it keeps crashing the game. I see the message "RAWR" and then the NullPointer exception is thrown. Am I using this method correctly? How do I get this method to not crash. I am on verison: 1.7.10-10.13.0.1191. Usage: private Minecraft mc; mc.theWorld.sendQuittingDisconnectingPacket(); mc.loadWorld((WorldClient) null, "RAWR"); while (mc.isIntegratedServerRunning()) try{ Thread.sleep(20); }catch (InterruptedException e){} Error: [14:41:12] [server thread/INFO]: Stopping server [14:41:12] [server thread/INFO]: Saving players [14:41:12] [server thread/INFO]: Saving worlds [14:41:12] [server thread/INFO]: Saving chunks for level 'New World'/Overworld [14:41:12] [server thread/INFO]: Saving chunks for level 'New World'/Nether [14:41:12] [server thread/INFO]: Saving chunks for level 'New World'/The End [14:41:13] [server thread/INFO] [FML]: Unloading dimension 0 [14:41:13] [server thread/INFO] [FML]: Unloading dimension -1 [14:41:13] [server thread/INFO] [FML]: Unloading dimension 1 [14:41:13] [server thread/INFO] [FML]: Applying holder lookups [14:41:13] [server thread/INFO] [FML]: Holder lookups applied [14:41:14] [Client thread/FATAL]: Unreported exception thrown! java.lang.NullPointerException at net.minecraft.client.Minecraft.runTick(Minecraft.java:2004) ~[Minecraft.class:?] at net.minecraft.client.Minecraft.runGameLoop(Minecraft.java:1038) ~[Minecraft.class:?] at net.minecraft.client.Minecraft.run(Minecraft.java:961) [Minecraft.class:?] at net.minecraft.client.main.Main.main(Main.java:164) [Main.class:?] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_11] at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) ~[?:1.8.0_11] at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) ~[?:1.8.0_11] at java.lang.reflect.Method.invoke(Unknown Source) ~[?:1.8.0_11] at net.minecraft.launchwrapper.Launch.launch(Launch.java:134) [launchwrapper-1.9.jar:?] at net.minecraft.launchwrapper.Launch.main(Launch.java:28) [launchwrapper-1.9.jar:?] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_11] at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) ~[?:1.8.0_11] at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) ~[?:1.8.0_11] at java.lang.reflect.Method.invoke(Unknown Source) ~[?:1.8.0_11] at GradleStart.bounce(GradleStart.java:108) [start/:?] at GradleStart.startClient(GradleStart.java:101) [start/:?] at GradleStart.main(GradleStart.java:66) [start/:?]
