Virtual block changes allow you to make it seem as if a block has changed on the client without actually changing any physical blocks in the world.
Sending a virtual block change to the client is as simple as calling the Viewer#sendBlockChange(int, int, int, BlockState) method. You will need to specify the co-ordinates of the block that you wish to change, as well as the new BlockState. An example is shown below:
import org.spongepowered.api.block.BlockTypes;
import org.spongepowered.api.effect.Viewer;
viewer.sendBlockChange(0, 65, 0, BlockTypes.COMMAND_BLOCK.getDefaultState());
This will make it seem as if the block at the co-ordinates 0, 65, 0
has changed to a command block. Of course, you
are not restricted to the default state of a block. Any BlockState
is accepted by the sendBlockChange()
method.
Besides specifying three integers for the co-ordinates, you may also specify a Vector3i
. An example of using the
Viewer#sendBlockChange(Vector3i, BlockState) method is shown below:
import com.flowpowered.math.vector.Vector3i;
Vector3i vector = new Vector3i(0, 65, 0);
viewer.sendBlockChange(vector, BlockTypes.COMMAND_BLOCK.getDefaultState());

To reset any changes you’ve made to the client at a specific location, you can call the
Viewer#resetBlockChange(int, int, int) method. For example, to undo our damage from the previous example, we
can call the resetBlockChange()
method specifying the co-ordinates from before:
viewer.resetBlockChange(0, 65, 0);
Note that you may also use a Vector3i
in place of the three integers with this method as well.
