(solved)[1.7.10]New way to destroy or delete a block from world?

[hotrods20]

In the code I'm importing to 1.7.10 from 1.6.4, I used World.destroyBlock(...) quite a bit but it doesn't work now and I can't see an obvious replacement for it.  Is there a new way to do it or do I have to find a workaround?

Same way, but the method name has not yet been deobfuscated: world.func_147480_a = world.destroyBlock

Thank you so much.  Didn't know that.  Also didn't see in Javadoc.  Very helpful.  I don't really like gradle....
