goingcrowd9 Posted November 1, 2018 Posted November 1, 2018 (edited) I'm not new to java, but i am to minecraft modding... Is there a way to make all glass (or custom glass blocks) blocks check for adjacent glass block and load diffrent textures based on that info ? i.e "if there is only a glass block left of this glass block, load xyz, else if..." I realise there are already "connected textures mods" but I'm trying to make my own, I just have no clue where data of the minecraft world is stored or wich methods check for the JSON files in ored to decide wich texture to load for wich blocks. Any help would be appreciated Edited November 9, 2018 by goingcrowd9 Quote
Draco18s Posted November 1, 2018 Posted November 1, 2018 Every block paramter is passed a World object and a BlockPos position argument (or three ints, x, y, and z). Get the neighbors and check their blockstate against the current one. And if you're on a version that passes x,y, and z, update. Because BlockIDs are not a thing you should touch. Quote Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice. Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked. DO NOT PM ME WITH PROBLEMS. No help will be given.
goingcrowd9 Posted November 1, 2018 Author Posted November 1, 2018 Thanks for the reply, I will try to get the blockstate of the adjacent blocks when I can. Quote

My other custom block loads just fine but apparently it doesn't load or register all variants correctly ? does anyone knows what I'm doing wrong ? EDIT: by removing "forge_marker": 1 the custom glass block now displays a texture now I just try to get the blockstates of adjacent blockstates and make the method 'canConnectSide' working.
