This has so much potential for horror maps! Great video

It does make things a lot creepier. :)

Hi, I have a question regarding the removal of items from a player's inventory. I am creating a map in which I want to create a mechanism where, when it starts raining, it removes 50% of all equipment. So let's say I have 8 apples and 4 sticks, I want it to remove these 4 apples and 2 sticks. Do you know how to do this?

[@InfernalDevice]

Hello. :) Sounds a bit tricky. You could count the number of apples using clear 0 and save that to a scoreboard, then divide that scoreboard by 2 and give that many number of apples back, but that would move all the items around, and you would need to do it for every item type in the game, which seems crazy. :) A better way would probably be to loop over every inventory slot using a macro, save the item id to storage and the item count to a score. Then divide the score by 2 and using another macro put the item back with the new count. I don't know how Minecraft deals with a score of 1 being divided by 2, is the result 0 or 1, although I suppose you could add a line like if score = 0 then set it to 1 if you wanted?

@@InfernalDevice Thanks for your answer! I think it is too complicated for me though and I will try to make a different but similar mechanism.

@@sotoso8680 I made a note of it and will have a play around at some point. Seems like an interesting thing to try. :)

Hello, I was going to play around with this, and I mentioned my ideas to GalSergey. They answered shortly after with the following, so all credit to them. :D It does the hotbar, inventory and offhand.
