Class BlockIterator

java.lang.Object
net.minestom.server.utils.block.BlockIterator
All Implemented Interfaces:
Iterator<Point>
public class BlockIterator extends Object implements Iterator<Point>
This class performs ray tracing and iterates along blocks on a line

  • Constructor Details

    • BlockIterator

      public BlockIterator(Vec start, Vec direction, double yOffset, double maxDistance, boolean smooth)
      Constructs the BlockIterator.

      This considers all blocks as 1x1x1 in size.

      Parameters:
      start - A Vector giving the initial position for the trace
      direction - A Vector pointing in the direction for the trace
      yOffset - The trace begins vertically offset from the start vector by this value
      maxDistance - This is the maximum distance in blocks for the trace. Setting this value above 140 may lead to problems with unloaded chunks. A value of 0 indicates no limit
      smooth - A boolean indicating whether the cast should be smooth. Smooth casts will only include one block when intersecting multiple axis lines.

    • BlockIterator

      public BlockIterator(Entity entity, int maxDistance)
      Constructs the BlockIterator.

      This considers all blocks as 1x1x1 in size.

      Parameters:
      entity - Information from the entity is used to set up the trace
      maxDistance - This is the maximum distance in blocks for the trace. Setting this value above 140 may lead to problems with unloaded chunks. A value of 0 indicates no limit
