  1. How can I get vanilla Minecraft source code with minimal distortion? (Not MCP)
  2. Here's my Block code: package com.gulgdev.mechanism.block.custom; import com.gulgdev.mechanism.block.ModBlocks; import net.minecraft.core.BlockPos; import net.minecraft.world.level.Level; import net.minecraft.world.level.block.BaseEntityBlock; import net.minecraft.world.level.block.entity.BlockEntity; import net.minecraft.world.level.block.entity.BlockEntityTicker; import net.minecraft.world.level.block.entity.BlockEntityType; import net.minecraft.world.level.block.state.BlockState; import javax.annotation.Nullable; public class Motor extends BaseEntityBlock { public Motor(Properties properties) { super(properties); } @Override public BlockEntity newBlockEntity(BlockPos pos, BlockState state) { return new MotorBlockEntity(pos, state); } @Nullable @Override public <T extends BlockEntity> BlockEntityTicker<T> getTicker(Level level, BlockState state, BlockEntityType<T> type) { return type == ModBlocks.MOTOR_BLOCK_ENTITY.get() ? (pLevel, pPos, pState, pBlockEntity) -> MotorBlockEntity.tick(pLevel, pPos, pState, pLevel.getBlockEntity(pPos)) : null; } } blockstates/motor.json: { "variants" : { "": { "model": "mechanism:block/motor" } } } models/block/motor.json: { "textures": { "0": "mechanism:block/motor_south", "1": "mechanism:block/motor_north", "2": "mechanism:block/motor_pipe", "3": "mechanism:block/motor_east", "4": "mechanism:block/motor_pipe_back", "5": "mechanism:block/motor_bottom", "6": "mechanism:block/motor_pipe_bottom", "particle": "mechanism:block/motor_south" }, "elements": [ { "from": [1, 3, 1], "to": [15, 14, 15], "faces": { "north": {"uv": [0, 0, 16, 16], "texture": "#1"}, "east": {"uv": [16, 0, 0, 16], "texture": "#3"}, "south": {"uv": [16, 0, 0, 16], "texture": "#0"}, "west": {"uv": [0, 0, 16, 16], "texture": "#5"}, "up": {"uv": [16, 16, 0, 0], "texture": "#5"}, "down": {"uv": [16, 0, 0, 16], "texture": "#5"} } }, { "from": [13.25, 1, 1], "to": [15, 3, 2.75], "faces": { "north": {"uv": [0, 0, 16, 16], "texture": "#2"}, "east": {"uv": [0, 0, 16, 16], "texture": "#4"}, "south": {"uv": [0, 0, 16, 16], "texture": "#4"}, "west": {"uv": [0, 0, 16, 16], "texture": "#4"}, "up": {"uv": [0, 0, 0.5, 0.5], "texture": "#missing"}, "down": {"uv": [0, 0, 16, 16], "texture": "#6"} } } ] } In inventory the block renders correct, but when I place it it's invisible.
  3. BlockState bs = level.getBlockState(pos); BaseEntityBlock beb = (BaseEntityBlock) bs.getBlock(); BlockEntity be = beb.newBlockEntity(to, bs); CompoundTag nbt_to = be.serializeNBT(); for (String key : nbt_from.getAllKeys()) { if (key != "id" && key != "x" && key != "y" && key != "z") { nbt_src.put(key, nbt.get(key)); } } be.deserializeNBT(nbt_to); nbt_from is nbt data which I want to copy to BE at position pos
  4. How can I change block entity data at specified position?

} }
  6. The position is loaded and block has BlockEntity (chest). But it returns null.
  7. BlockEntity otherBE = level.getBlockEntity(blockEntityPos); otherBE always null.
  8. public static <T extends BlockEntity> void tick(Level level, BlockPos pos, BlockState state, T be) { if (level.isClientSide()) return; // I want to get other BE by position which I have in other variable (otherPos) }
  9. But I need to get BE before. I have only position.
