Need Help with NullPointerException

Recommended Posts

Hello, S I'm making a new Furnace with 5 input slots, but whenever I try to open the gui of the block it crashes the game and I get this error report:

 

java.lang.NullPointerException

at net.minecraft.src.Slot.getStack(Slot.java:77)

at net.minecraft.src.GuiContainer.drawSlotInventory(GuiContainer.java:202)

at net.minecraft.src.GuiContainer.drawScreen(GuiContainer.java:72)

at net.minecraft.src.EntityRenderer.updateCameraAndRender(EntityRenderer.java:972)

at net.minecraft.client.Minecraft.runGameLoop(Minecraft.java:873)

at net.minecraft.client.Minecraft.run(Minecraft.java:750)

at java.lang.Thread.run(Unknown Source)

 

i have no idea what I'm supposed to do with that.

 

Please don't hate on me if this is a simple fix, I just can't figure it out.

 

Also, if you need code, i will give it.

Somehow, you're having a different Slot class then I.

But it looks like somehow the slot inventory is null.

Figure out how you created a clot with a null inventory.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

hmm, seems legit, but I can't figure out where, though.....

    • I have been trying to download Forge but the Windows Installer isn't coming up, I can see the installer one would use for Linux but no Windows, I have downloaded Java and Jarfix but nothing is working, can someone help?  
    • So I thought that when a capability is attached to an item/entity/etc... the capability will stay until whatever it's attached to is gone. But this doesn't seem to be the case, as when I printed to console whenever a capability is attached, it seems as though a new version of the capability is attached to an item every time I select it in my hotbar, hover over it in inventory, etc. Is this how it's supposed to work? If so, why?
    • Hi, I'm trying to set up a simple forge server just to play with a couple of my friends, but no matter what I do or try I cannot seem to get a Mods folder and for the actual forge part of the server to actually launch. Every time I try to launch the forge.jar via a .bat file I just get a bunch of errors [Errors below] I'm not sure what I'm doing wrong. If I can get some help that would be awesome, thanks C:\Users\User\Desktop\Server>java -Xms2G -Xmx6G -jar forge-1.12.2-14.23.5.2855.jar nogui A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException         at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)         at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:78)         at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)         at java.base/java.lang.reflect.Method.invoke(Method.java:567)         at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.run(ServerLaunchWrapper.java:70)         at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.main(ServerLaunchWrapper.java:34) Caused by: java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap')         at net.minecraft.launchwrapper.Launch.<init>(Launch.java:34)         at net.minecraft.launchwrapper.Launch.main(Launch.java:28)         ... 6 more C:\Users\User\Desktop\Server>pause Press any key to continue . . .
