It's line 36 in the class constructor that shows up as the error with the crash report, after it crashes before it finishes starting up, the line that says:

 

this.setDefaultState(this.blockState.getBaseState().withProperty(VARIANT, MagicPlank.EnumType.MAGIC));

 

And this is the error message:

 

Caused by: java.lang.IllegalArgumentException: Cannot set property PropertyEnum{name=variant, clazz=class net.minecraft.block.BlockPlanks$EnumType, values=[oak, spruce, birch, jungle, acacia, dark_oak]} as it does not exist in BlockStateContainer{block=null, properties=[variant]}

I'm sorry if this is a rookie mistake or something. I am experienced with Java, just not Minecraft Forge modding.

Is this being properly overriden?

 

and how are you registering your block??

Can you post your entire log using GitHub Gist or pastebin and your code as a github(or similar) repository?

Thank you Cadiboo, putting @Override at the line over:

 

protected BlockStateContainer createBlockState()
    {
        return new BlockStateContainer(this, new IProperty[] {VARIANT});
    }

 

fixed the crash on startup. Updated code:

code formatting

This is impossible. Adding @Override never changes how your code behaves, except maybe making it not compile anymore in case you are not actually overriding.

It ONLY fixed the crash on startup, ONLY. It's still bugged. Sorry, I should have specified. But the crash on startup is fixed, I feel that I can do all the rest of the debugging on my own, and if I can't, I'll ask on this forum for help if I can't figure it out.

Use your IDE's auto-formatter function to automatically apply overrides etc.

Again, it is impossible that adding @Override has achieved this. You have done something else.

I have to admit, I made all this post and comments late at night when very sleepy. So I truly honestly do not remember if I did anything else, sorry.
