and I'm not sure what should I do to archive a interaction with my block and redstone wire, levers, buttons, etc...

Why not take a look at the vanilla blocks that interact with redstone the way you want it to?


I will be posting 1.15.2 modding tutorials on this channel. If you want to be notified of it do the normal YouTube stuff like subscribing, ect.

Forge and vanilla BlockState generator.

I have spent some time immersed in the minecraft code and I have managed to learn slightly how the redstone system works.


The fisrt part is to add and manage properties of your custom block.

To add a property we have to declarate de property itself, initialize and overload fillStateContainer.

//Step 1: declaration
public static final IntegerProperty POWER = BlockStateProperties.POWER_0_15;
public static final IntegerProperty POWERED = BlockStateProperties.POWERED;
//In your Custom Block Class Constructor (Initialize)
this.setDefaultState(this.getDefaultState().with(POWER, 0).with(POWERED, true));//How many properties as you want

//Last Step
public void fillStateContainer(StateContainer.Builder<Block,BlockState> builder) {
  builder.add(POWERED,POWER);//How many properties as you want

We can change the property value overloading event method like "OnBlockAdded", "OnRemplaced", "neighborChanged"

To change the value of a property we need the World, BlockState and BlockPos

 state = state.with(POWER, Integer.valueOf(15)) //State:BlockState

 world.setBlockState(pos, state, 2);//world:World && pos:BlockPos


The second part allow other blocks to recognize that has power or if it is a power source.

To archive this we have to overload two or three methods of "net.minecraft.block.Block

public boolean canProvidePower(BlockState state) ...

public int getStrongPower(BlockState blockState, IBlockReader blockAccess, BlockPos pos, Direction side) ...

public int getWeakPower(BlockState blockState, IBlockReader blockAccess, BlockPos pos, Direction side) ...
