Alicrack

Thank you for support, I already found carvedPumpkinOverlay in ForgeInGameGui and will use it

Thanks,but I still do not understand what BufferBuilder is, also, do you have any learning material about rendering I can take lesson from?

I want to overlay a texture on top of the screen, like carved pumpkins do when equipped or when a totem of undying is being used, and dont know how can i implement it. I tried looking inside of carved pumpkins code, totem of undying or anywhere else, but didnt find anything related. Also, I want implement this texture overlay behaviour through renderParticle method in my CustomParticle class

This create() method is a part of a Piece extends TemplateStructurePiece class, which is called in my init() method through this.components.add method, maybe I should put a code here? Here's my structure piece code: package com.alicrack.thebackrooms.world.structures; import java.util.List; import java.util.Random; import com.alicrack.thebackrooms.TheBackrooms; import net.minecraft.block.BlockState;

} } @Override public boolean canBeGenerated(BiomeManager biomeManagerIn, ChunkGenerator<?> generatorIn, Random randIn, int chunkX, int chunkZ, Biome biomeIn) { // TODO Auto-generated method stub return true;

So, I'm trying to use findNearest (one that returns BlockPos of a structure) function in my create() method of my custom StructurePiece class and don't know the way I can get the instance of the World for that findNearest function Can anyone help?
