[1.8][Solved]Updating "in-game NBTEdit" From 1.7 to 1.8 Object Reflections

[nekpek]

So I pulled hes project from https://github.com/DavidGoldman/NBTEdit

To update hes mod for personal use. After several fix's and patches i succeeded to remove the errors in Eclipse

however when i want to edit a chest with items it crashes with this error

Caused by: java.lang.ClassCastException: org.apache.logging.log4j.core.Logger cannot be cast to java.util.List

The Section in question here is

 

    public static NBTBase getTagAt(NBTTagList tag, int index) {
        List<NBTBase> list = ReflectionHelper.getPrivateValue(NBTTagList.class, tag, 0);
        return list.get(index);
        
    }
}

I have also been looking into the other Class' which cast an error but nowhere do it look like its ever been a org.apache.logging.log4j.core.Logger type.

i have been trying to changing different things but all is casting the same error that Logger cant be cast into what i try.

 

The mod does however work if the chest is empty, but then crashes with the same error after i mannually add a TAGCompound. (like i would do it in 1.7)

 

 

[nekpek]

But what would i use if not ReflectionHelper?

 

Also index is just the TagCount looped in a For event. so i can get every tag

perhaps that is the problem but how do i know which tag is the "logger"

and why wasn't this(the logger) present in 1.7.10? (as this code is confirmed to compile and work in 1.7.10)

Use ReflectionHelper.findField.

[nekpek]

when using

Field field = ReflectionHelper.findField(NBTTagList.class, tag.getStringTagAt(index));

 

I get this error

java.lang.NoSuchFieldException: {id:"minecraft:chest",Damage:0s,Count:1b,Slot:13b,}

The "id:"minecraft:chest",Damage:0s,Count:1b,Slot:13b," is the part that i want to return as a List<NBTBase>.

so how would i go to first fix the error and second make it into the desired type?

 

Since i thought it might be caused cause the Tag.getStringtagAt

i thought perhaps i could get the entire "field" using

Field field = ReflectionHelper.findField(NBTTagList.class)

but this gets me

"Caused by: net.minecraftforge.fml.relauncher.ReflectionHelper$UnableToFindFieldException"

 

I dont think i understand the findField, and when i looked up how it was coded it reminded a bit of getPrivateValue so i dont really know how it would be "better."

[nekpek]

Oh doh yeah hehe.

I see what i did wrong there xP

 

I got it to work now =D

 

Thank you all!
