Differentiation Posted January 22, 2018 Posted January 22, 2018 (edited) Hey! I was wondering, is there any way to yield the player with a random item or block from Minecraft or my own mod? Is it just as simple as giving the player a random item by getting a random item id? Any suggestions are welcome. Thank you! Edited January 22, 2018 by Differentiation Quote
jabelar Posted January 22, 2018 Posted January 22, 2018 Well, as long as it is valid, yes. But since it is a registry system I wouldn't call it an "id" but rather the "key" for the related collection. So you can get the list of keys from the appropriate registry and then pick a random one from the list. Find the registry and then look at the available methods to get ideas on how to get the keys. Picking a random one then just requires typical Java technique -- I'm pretty sure you can just google "get random entry from Java list" to get examples. 1 Quote Check out my tutorials here: http://jabelarminecraft.blogspot.com/

It should be straightforward to find out which you need. Expand Item is a list of all Items and Blocks, or just Items? List<Item> items = Lists.newArrayList(ForgeRegistries.ITEMS.getValues()); Random rand = new Random(); Item item = items.get(rand.nextInt(items.size())); Edited January 22, 2018 by Differentiation Quote

Why do you want both, though? You cannot usefully use them in the same way. Expand I want the player to obtain a random item or block from right clicking an item. Quote
