Compilation error when copying source code
Tue, 03/19/2019 - 18:34

Recently I was trying to make custom tnt, however I don't know how to write the code so I decided to copy one from original minecraft(source in mcreator).

So, everytime when I try to compile it, gradle gives me an error "connot find symbol ()"
public void (...)
BUT parentheses "()" are already there and the code is correct.
 


I have no idea why it's not working as expected. Please help to solve this issue somehow.

The compiler is never wrong. If you get errors with Java syntax, the code is not ok. Paste the code.

You need to define block state variable EXPLODE. You have some missing parts of the code to make this work.
