Failender

show ur attempts, ask specific questions

To answer your question, yes should be possible.

u will need to find the surface block, I am not sure if vanilla has a method for that, or if u need to iterate over the blocks in the world until u find a grass block. after that add 1 to the y pos and u are above the grass

and what would neutral do? nothing? EDIT: Take a look at the Redstone class. There is a lot of things to read that might already solve ur questions

seems like my answer got cut. sorry. public ItemStack onItemRightClick(ItemStack Item, World world, EntityPlayer player) { if(!world.isRemote) { doWorldChangesHere(); } show the crash log, should not be happening.

Specifiy please. u mean a cable with negative redstone power?

U can access the actual open container of the player by player.openContainer. Which means u can use a PlayerTickEvent, iterate through the items of the open container, check the nbt tags, and after that dance to some music.

Alright. I know that I am missing something totally dumb. I want to know something custom above the food icons of the player. I know that I need to scale my rendering. But I am to dumb to get the math right now. The y pos is always correct, the x pos gets messed up by changing the size of minecraft. Any help is appreciated.

best way to find out if u are on server or client side are world objects. world.isRemote tells u that. world.isRemote=> client !world.isRemote =>server. void onItemRightClick(tons of arguments including world object) {

this copypasted code is obfuscated. I guess ur dev environment is deobfuscated. which means that you need to find the deobfuscated fields names.

show how u call the method. i bet u are calling it on client side, which is wrong. u need to call it on server side.

nothing to add.

u can save the time of creation/ the expire data in the items nbt and validate that every time u want do so. so u know "this steak was created 100 ticks ago" and if the steak is 200 ticks old make it to rotten flesh or sth like that

U went to far. Seriously.

more information please. which method are u talking about? which class?

normally if synchronized right vanilla will do that for you. I am not sure if they pull the information from openContainer or inventory. But they should be rendering the stuff they find inside that.

Alright. I will tell you what I know, but as I said I abandoned this try because I wasnt able to fix all problems occuring. The player has two instances of his inventory. Player#inventory Player#openContainer Overriding these two is the first step of chaning the player inventory. If you do that u wont have a need to interrupt the keys, because they will fetch the data from the overwritten instances.

should work since ur gui isnt doing anything on server side. just send a packet for selecting the weapon

Hmm I might be wrong there. If u are able to find out where the player gets knockbacked (from attacks etc) u will find ur solution for sure

use the id of the entity, they are synced between server and client.

u need to use the PlayerInteractEvent, like u did earlier not create a PlayerInteractEvent.

dont message the client about its motion. set it on the server, just like u have done for everythign else then player

U should try fixxing problems urself instead of asking for help if u cant find the problem in ten minutes

well. I know that if I wont answer u for half an hour u will have it fixxed :'D
