Fields

Modifier and Type	Field and Description
protected BoundingBox[]	boundingBoxes
protected ThreadLocal<com.nukkitx.math.vector.Vector3i>	position
protected double	pushAwayTolerance This is used to control the maximum distance a face of a bounding box can push the player away
protected double	pushUpTolerance This is used for the step up logic.

Method Summary

Modifier and Type	Method and Description
void	beforeCorrectPosition(BoundingBox playerCollision) Overridden in classes like SnowCollision and GrassPathCollision when correction code needs to be run before the main correction
boolean	checkIntersection(BoundingBox playerCollision)
boolean	correctPosition(GeyserSession session, BoundingBox playerCollision) Returns false if the movement is invalid, and in this case it shouldn't be sent to the server and should be cancelled While the Java server should do this, it could result in false flags by anticheat This functionality is currently only used in 6 or 7 layer snow
void	setPosition(com.nukkitx.math.vector.Vector3i newPosition)

Field Detail

boundingBoxes

protected final BoundingBox[] boundingBoxes

position

protected final ThreadLocal<com.nukkitx.math.vector.Vector3i> position

pushUpTolerance

protected double pushUpTolerance

This is used for the step up logic. Usually, the player can only step up a block if they are on the same Y level as its bottom face or higher For snow layers, due to its beforeCorrectPosition method the player can be slightly below (0.125 blocks) and still need to step up This used to be 0 but for now this has been set to 1 as it fixes bed collision I didn't just set it for beds because other collision may also be slightly raised off the ground. If this causes any problems, change this back to 0 and add an exception for beds.

pushAwayTolerance

protected double pushAwayTolerance

This is used to control the maximum distance a face of a bounding box can push the player away

Constructor Detail

BlockCollision

protected BlockCollision(BoundingBox[] boxes)

Method Detail

setPosition

public void setPosition(com.nukkitx.math.vector.Vector3i newPosition)

beforeCorrectPosition

public void beforeCorrectPosition(BoundingBox playerCollision)

Overridden in classes like SnowCollision and GrassPathCollision when correction code needs to be run before the main correction

correctPosition

public boolean correctPosition(GeyserSession session,
                               BoundingBox playerCollision)

Returns false if the movement is invalid, and in this case it shouldn't be sent to the server and should be cancelled While the Java server should do this, it could result in false flags by anticheat This functionality is currently only used in 6 or 7 layer snow

checkIntersection

public boolean checkIntersection(BoundingBox playerCollision)
