 float strength)

Method Details

getStrength

public float getStrength()

getCenterX

public float getCenterX()

getCenterY

public float getCenterY()

getCenterZ

public float getCenterZ()

prepare

protected abstract List<Point> prepare(Instance instance)

Prepares the list of blocks that will be broken. Also pushes and damage entities affected by this explosion

Parameters:

instance - instance to perform this explosion in

Returns:

list of blocks that will be broken.

apply

public void apply(@NotNull
 @NotNull Instance instance)

Performs the explosion and send the corresponding packet

Parameters:

instance - instance to perform this explosion in

postExplosion

protected void postExplosion(Instance instance,
 List<Point> blocks,
 ExplosionPacket packet)

Called after removing blocks and preparing the packet, but before sending it.

Parameters:

instance - the instance in which the explosion occurs

blocks - the block positions returned by prepare

packet - the explosion packet to sent to the client. Be careful with what you're doing. It is initialized with the center and radius of the explosion. The positions in 'blocks' are also stored in the packet before this call, but you are free to modify 'records' to modify the blocks sent to the client. Just be careful, you might just crash the server or the client. Or you're lucky, both at the same time.

postSend

protected void postSend(Instance instance,
 List<Point> blocks)

Called after sending the explosion packet. Can be used to (re)set blocks that have been destroyed. This is necessary to do after the packet being sent, because the client sets the positions received to air.

Parameters:

instance - the instance in which the explosion occurs

blocks - the block positions returned by prepare
