```
public interface WorldBorder
```
A world border is a square boundary, extending through the entire y-axis.
It can gradually grow or shrink to a radius over a period of time. A warning is displayed when a contracting world border will reach the player in a certain amount of time, or when the player is a certain number of blocks away.

In Minecraft, a warning is displayed in the form of a reddish tint.

- Method Detail
  - builder
```
static WorldBorder.Builder builder()
```
    Creates a new WorldBorder.Builder instance for making WorldBorders.
    
    Returns:
    
    The builder
  - defaultBorder
```
static WorldBorder defaultBorder()
```
    Gets a WorldBorder that represents the default border values for a newly created overworld.
    
    Returns:
    
    A WorldBorder that represents the default values
  - toBuilder
```
default WorldBorder.Builder toBuilder()
```
    Creates a new WorldBorder.Builder instance for making WorldBorders, pre-populated with the values of this border.
    
    Returns:
    
    The builder
  - center
```
Vector2d center()
```
    Gets the center of the world border.
    The x coordinated can be retrieved through Vector2d.x(), while the z coordinated can be retrieved through Vector2d.y().
    
    Returns:
    
    The center
  - diameter
```
double diameter()
```
    Gets the current diameter of this world border. If this is an immutable border, this is the initial diameter.
    The returned diameter applies to the x and z axis. The world border extends over the entire y-axis.
    
    Returns:
    
    The size
  - targetDiameter
```
double targetDiameter()
```
    Gets the target diameter the world border is expanding or contracting to.
    This will return the same value as diameter() unless timeUntilTargetDiameter() is greater than 0.
    
    Returns:
    
    The diameter being changed to
  - timeUntilTargetDiameter
```
Duration timeUntilTargetDiameter()
```
    Gets the time remaining until the world border stops expanding or contracting to the targetDiameter().
    If diameter() and targetDiameter() are the same, this will be Duration.ZERO.
    
    Returns:
    
    The time remaining
  - safeZone
```
double safeZone()
```
    Gets the distance a player may be outside the world border before taking damage.
    
    Returns:
    
    The distance
  - damagePerBlock
```
double damagePerBlock()
```
    Gets the damage done to a player per block per tick when outside the buffer.
    
    Returns:
    
    The damage amount
  - warningTime
```
Duration warningTime()
```
    Gets the time when a contracting world border will warn a player for whom the world border will reach in time seconds.
    In Minecraft, the warning is displayed in the form of a reddish tint.
    
    Returns:
    
    The warning time
  - warningDistance
```
int warningDistance()
```
    Gets the distance when a contracting world border will warn a player for whom the world border is distance away.
    In Minecraft, the warning is displayed in the form of a reddish tint.
    
    Returns:
    
    The distance
