I have been making a few small simples things in Java, making plugins. I made a /heal command, /creative command, and even a nicknaming command that changes your chat username! But now, I got a really good idea. I would make a /tp command, but make it better then the one that is currently in Vanilla Minecraft. I would make it so right before you teleport, TNT explodes where you are before you teleport. Kinda like a smoke grenade. Unfortunately, I'm still try to find out how to cause an explosion with any delay... I will post a video when I am done.
