Oh, sorry. The branch is 1.11.2 not master. I have just edited it!

I tried to clone your repository and debug this for myself, but your code is full of compilation errors, missing packages, etc. And you even have a broken dependency in your build.gradle.

I am very sory but this is the first time I used github.

Not sure what this has to do with Github...

Expand  

So could you complie it?

No, there are entire packages missing. "network" for example is referenced, but not present.

Expand  

Could you tell me what class used the network package? I remembered removing it.

Now I have synced the code in the github with my project. And I have fixed all the compliations error. Thank you for your patient!

Your code still does not compile. Are you not checking your code before you push? Do you not use an IDE?

Expand  

 I use eclipse and it is correctly. It can run. What do you mean it does not complie?

Oh, I am so stupid. When I upload the source to github, I forgot to delete the code that I didn't not use in the project. This is really dumb, right?

What are you even doing? What do you mean by "upload"? Are you not using Git from the command line?!

Expand  

No, I'm using git gui.

I'm really like a dumb guy who wanted to develop minecraft mods.

I placed down a freezer (which has no textures, btw.). Right-clicking it does nothing.

Thanks for your help but I fixed that. Thanks anyway!
