QcBlastBlocks Class

The block side of explosions (decision E-602): the cells a blast breaks wait in order and are worked through at most explosionBlocksPerTick per tick (QcServerLimits), the rest in the next ticks; nothing is ever lost on the way, but a cell whose chunk left the world in the meantime is skipped.

Detailed Description

A cell holding an explosive is not broken but handed back to be lit (a chain reaction); any other cell becomes air quietly, drops its items with the blast's chance, lets the plants and an infested block react, and with a blast that sets fires may catch fire. Doors and beds break as a whole through QcServerBlocks. The clients get every cell set in a tick as one QcMsg::BlockBatch (several when there are more than QcMsg::BlockBatch::maxUpdates), so they relight and mesh each section once.

Member Function Documentation

void QcBlastBlocks::add(const QList<QcBlockPos> &cells, const QcBlastBlocks::Effects &effects)

Adds the cells a blast with effects breaks to the waiting cells.

quint64 QcBlastBlocks::broken() const

Returns the blocks broken since the server started.

bool QcBlastBlocks::clear(QcBlockPos pos)

Sets pos to air without telling the clients yet (a lit explosive leaves its cell). Returns false when the block could not be set.

void QcBlastBlocks::drop()

Forgets the waiting cells (the game rule explosionBlockDamage was switched off).

void QcBlastBlocks::flush()

Sends the cells set since the last flush to the clients that have their chunks, then lights the fires of blasts with fire.

`[static]` QList<QcMsg::BlockBatch> QcBlastBlocks::pieces(const QList<QcMsg::BlockUpdate> &updates, qsizetype most)

Returns updates cut into batches of at most most updates each, in order.

QList<QcPlacedBlock> QcBlastBlocks::take(qint64 budget)

Works through at most budget waiting cells; returns the explosives among them, still in place.

qsizetype QcBlastBlocks::waiting() const

Returns the number of waiting cells.
