Interface TeleportHelperFilter

All Superinterfaces:

CatalogType

@CatalogedBy(value=TeleportHelperFilters.class)
public interface TeleportHelperFilter
extends CatalogType

A TeleportHelperFilter contains routines to determine whether a location is a suitable candidate for teleporting to safely.

Method Summary

Modifier and Type	Method and Description
boolean	isSafeBodyMaterial(BlockState blockState) Tests whether a BlockState should be considered a safe block for the body to be inside of.
boolean	isSafeFloorMaterial(BlockState blockState) Tests whether a BlockState should be considered a safe block to land on.
default Tristate	isValidLocation(World world, com.flowpowered.math.vector.Vector3i position) Tests whether the location in question is valid, regardless of whether the block is safe or not.

Method Detail

isValidLocation

default Tristate isValidLocation(World world,
                                 com.flowpowered.math.vector.Vector3i position)

Tests whether the location in question is valid, regardless of whether the block is safe or not. This is only intended to be used by kernels that blacklist/whitelist certain locations, and any block checks should be performed by isSafeFloorMaterial(BlockState) and isSafeBodyMaterial(BlockState) instead, to obtain the full benefits of the TeleportHelper.

• Returning Tristate.UNDEFINED denotes that the filter does not regard the location as valid or otherwise, and that the helper should determine if the location is suitable using the isSafeBodyMaterial(BlockState) and isSafeFloorMaterial(BlockState) methods. Implementations should generally return this result.
• Returning Tristate.TRUE marks the location as valid and will causes the parent TeleportHelper to return this location. No checks using isSafeBodyMaterial(BlockState) and isSafeFloorMaterial(BlockState) will be performed.
• Returning Tristate.FALSE marks the location as invalid and causes the parent TeleportHelper to move onto the next block to check, regardless of whether it would have otherwise been marked as safe.

This method has a default implementation of always returning Tristate.UNDEFINED, that is, such a filter is not location specific.

This will be called before any other check on the target location is performed, this is the first check performed when investigating a location.

Parameters:

world - The World to check

position - The Vector3i (block position) to check

Returns:

A Tristate

isSafeFloorMaterial

boolean isSafeFloorMaterial(BlockState blockState)

Tests whether a BlockState should be considered a safe block to land on.

Parameters:

blockState - The BlockState to check

Returns:

true if the material should be safe to land on

isSafeBodyMaterial

boolean isSafeBodyMaterial(BlockState blockState)

Tests whether a BlockState should be considered a safe block for the body to be inside of.

Generally, you want this to be a passable block!

Parameters:

blockState - The BlockState to check

Returns:

true if the material should be safe for the body to be inside of
