[1.14.4][Solved] how to make my block interact with redstone

[Brbcode]

I've been writing my own capabilities lately, and I'm not sure what should I do to archive a interaction with my block and redstone wire, levers, buttons, etc...

Any info is welcome.

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

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

PART ONE

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
@Override
public void fillStateContainer(StateContainer.Builder<Block,BlockState> builder) {
  super.fillStateContainer(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

PART TWO

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" 

@Override
public boolean canProvidePower(BlockState state) ...

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

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