[SOLVED] [1.7.10] TNT Doesn't Explode Properly

Posted January 11, 201510 yr

Hi guys I'm making a Wireless TNT Activator to istantly explode tnt's. Well, all goes fine, the tnt explode if i right click the item but the explosion makes a strange "barrier" that disappear if i exit the world. So it generates this "barrier" only when explode, the next time i will enter the world this "barrier" has disappeared.

Because it's hard to describe and my english is not so that well because i'm not english i made a video to show what happens (the problem described above)

Also, of course, here is the source code. Thanks in advance for all who will help me

Don't blame me if i always ask for your help. I just want to learn to be better

First thought after watching the video is that the "barrier" is most likely caused by a both the client and the server ran the code for the explosion, causing blocks to be destroyed, but not exactly the same blocks on both sides. The "barrier" is that the block you're trying to enter (which doesn't exist on client side) does exist on the server side. Reloading the world simply syncs the data between the server and client, which is why it fixes the problem.

You might want to try adding an if (!world.isRemote) check in your code to be sure the blocks are only destroyed on server side.
