Constructor Details

BlockIterator

public BlockIterator(@NotNull
 @NotNull World world,
 @NotNull
 @NotNull Vector start,
 @NotNull
 @NotNull Vector direction,
 double yOffset,
 int maxDistance)

Constructs the BlockIterator.

This considers all blocks as 1x1x1 in size.

Parameters:

world - The world to use for tracing

start - A Vector giving the initial location 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

BlockIterator

public BlockIterator(@NotNull
 @NotNull Location loc,
 double yOffset,
 int maxDistance)

Constructs the BlockIterator.

This considers all blocks as 1x1x1 in size.

Parameters:

loc - The location for the start of the ray 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

BlockIterator

public BlockIterator(@NotNull
 @NotNull Location loc,
 double yOffset)

Constructs the BlockIterator.

This considers all blocks as 1x1x1 in size.

Parameters:

loc - The location for the start of the ray trace

yOffset - The trace begins vertically offset from the start vector by this value

BlockIterator

public BlockIterator(@NotNull
 @NotNull Location loc)

Constructs the BlockIterator.

This considers all blocks as 1x1x1 in size.

Parameters:

loc - The location for the start of the ray trace

BlockIterator

public BlockIterator(@NotNull
 @NotNull LivingEntity 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

BlockIterator

public BlockIterator(@NotNull
 @NotNull LivingEntity entity)

Constructs the BlockIterator.

This considers all blocks as 1x1x1 in size.

Parameters:

entity - Information from the entity is used to set up the trace
