Kinson Studio's video: Minecraft MTR PE Windows 10 Server - New lava TNT and End Crystal detecting system demonstration

This video shows how the new anti-destruction system on the Minecraft MTR (PE/Windows 10 Edition) server works. Its main purpose is to prevent unfortunate incidents such as lava griefing and TNT explosions to happen on the server by detecting the presence of lava, TNT and End Crystals in players' inventories and whether or not they are placed on blocks. Commonly, and according to our observations, if a player were attempting to cause damage to the server, they would usually use lava, TNT or End Crystal's explosion as those are some of the easiest methods to achieve their goal. Consequently, the anti-destruction system is critical for griefing prevention. With this anti-destruction system, whenever a player tries to get a lava bucket, TNT, TNT minecart or End Crystal in their inventory (even with using the /give command) or place it down (even with the /fill, /setblock or /summon command), it is being detected and a fullscreen warning message will instantly pop up (by the command /title @a) to alert admins and other players that something bad is about to happen. Fortunately, since several command blocks (30+) are constantly functioning to remove those items with the /clear @a command, it would not let players obtain those items and thus prevent incidents to happen. When it comes to damages caused by mobs, except the Ender Dragon, other hostile mobs or any other mob that could cause damage could not be spawned because the game difficulty is forced to set to peaceful. Since the Ender Dragon is exempt from this, a command block is set specifically to kill it upon spawning with the /kill command, therefore it should be just fine. We hope this anti-destruction system could minimize damages occurring on the server. But apart from that, the more important message I would like to convey is that why would one want to destroy the hard work by other people? What is the point of doing it? I think that is just selfish and a waste of everyone's time. I hope from now on, we would not need to use this system or see those popup messages ever again, only if and when it is necessary. Lastly, I would like to give a big thank you to Kyle and Advincula for helping me to set up the command blocks and Redstone stuff. I am not a pro at Minecraft commands. They are geniuses!
