◆ AbsoluteToRelative()

static Vector3f Explodinator::AbsoluteToRelative	(	const Vector3f	a_Position,
		const cChunkCoords	a_ChunkPosition
	)

static

Converts an absolute floating-point Position into a Chunk-relative one.

Definition at line 26 of file Explodinator.cpp.

◆ BlockAlwaysDrops()

static bool Explodinator::BlockAlwaysDrops ( const BLOCKTYPE a_Block )

static

Returns true if block should always drop when exploded.

Currently missing conduits from 1.13

◆ CalculateEntityExposure()

static float Explodinator::CalculateEntityExposure	(	const cChunk &	a_Chunk,
		const cEntity &	a_Entity,
		const Vector3f	a_Position,
		const int	a_SquareRadius
	)

static

Calculates the approximate percentage of an Entity's bounding box that is exposed to an explosion centred at Position.

Definition at line 163 of file Explodinator.cpp.

◆ DamageBlocks()

static void Explodinator::DamageBlocks	(	cChunk &	a_Chunk,
		const Vector3f	a_Position,
		const int	a_Power,
		const bool	a_Fiery,
		const cEntity *const	a_ExplodingEntity
	)

static

Sends out Explosion Lazors (tm) originating from the given position that destroy blocks.

Definition at line 383 of file Explodinator.cpp.

◆ DamageEntities()

static void Explodinator::DamageEntities	(	const cChunk &	a_Chunk,
		const Vector3f	a_Position,
		const int	a_Power
	)

static

Applies distance-based damage and knockback to all entities within the explosion's effect range.

Definition at line 205 of file Explodinator.cpp.

◆ DestroyBlock()

static void Explodinator::DestroyBlock	(	cChunk &	a_Chunk,
		const Vector3i	a_Position,
		const int	a_Power,
		const bool	a_Fiery,
		const cEntity *const	a_ExplodingEntity
	)

static

Work out what should happen when an explosion destroys the given block.

Tasks include lighting TNT, dropping pickups, setting fire and flinging shrapnel according to Minecraft rules. OK, mostly Minecraft rules.

Definition at line 277 of file Explodinator.cpp.

◆ DestructionTrace()

static void Explodinator::DestructionTrace	(	cChunk *	a_Chunk,
		Vector3f	a_Origin,
		const Vector3f	a_Direction,
		const int	a_Power,
		const bool	a_Fiery,
		float	a_Intensity,
		const cEntity *const	a_ExplodingEntity
	)

static

Traces the path taken by one Explosion Lazor (tm) with given direction and intensity, that will destroy blocks until it is exhausted.

Definition at line 333 of file Explodinator.cpp.

◆ GetExplosionAbsorption()

static float Explodinator::GetExplosionAbsorption ( const BLOCKTYPE Block )

static

Returns how much of an explosion Destruction Lazor's (tm) intensity the given block attenuates.

Values are scaled as 0.3 * (0.3 + Wiki) since some compilers miss the constant folding optimisation. Wiki values are https://minecraft.wiki/w/Explosion#Blast_resistance as of 2021-02-06.

Definition at line 45 of file Explodinator.cpp.

◆ Kaboom()

void Explodinator::Kaboom	(	cWorld &	World,
		Vector3f	Position,
		int	Power,
		bool	Fiery,
		const cEntity *	a_ExplodingEntity
	)

Creates an explosion of Power, centred at Position, with ability to set fires as provided.

For maximum efficiency, Position should be in the centre of the entity or block that exploded. The entity pointer is used to trigger OnBreak for the destroyed blocks. Kaboom indeed, you drunken wretch.

Definition at line 432 of file Explodinator.cpp.

◆ LagTheClient()

static void Explodinator::LagTheClient	(	cChunk &	a_Chunk,
		const Vector3f	a_Position,
		const int	a_Power
	)

static

Sends an explosion packet to all clients in the given chunk.

Definition at line 424 of file Explodinator.cpp.

static float Explodinator::RandomIntensity	(	MTRand &	a_Random,
		const int	a_Power
	)

static

Returns a random intensity for an Explosion Lazor (tm) as a function of the explosion's power.

Definition at line 377 of file Explodinator.cpp.

◆ RebaseRelativePosition()

static Vector3f Explodinator::RebaseRelativePosition	(	const cChunkCoords	a_From,
		const cChunkCoords	a_To,

		const cEntity *const	a_ExplodingEntity
	)

static

Sets the block at the given position, updating surroundings.
