Constructor Detail

AbstractAttackEntityEvent

public AbstractAttackEntityEvent()

Method Detail

init

protected final void init()

Description copied from class: AbstractEvent

Called once all fields have been set by the generated constructor in a subclass.

This method should be used to initialize any fields that depend on parameters passed to the constructor.

Overrides:

init in class AbstractEvent

getOriginalModifierDamage

public final double getOriginalModifierDamage(DamageModifier damageModifier)

Description copied from interface: AttackEntityEvent

Gets the original damage for the provided DamageModifier. If the provided DamageModifier was not included in AttackEntityEvent.getOriginalDamages(), an IllegalArgumentException is thrown.

Specified by:

getOriginalModifierDamage in interface AttackEntityEvent

Parameters:

damageModifier - The original damage modifier

Returns:

The original damage change

getOriginalFinalDamage

public final double getOriginalFinalDamage()

Description copied from interface: AttackEntityEvent

Gets the original "final" amount of damage after all original DamageModifiers are applied to AttackEntityEvent.getOriginalDamage(). The "final" damage is considered the amount of health being lost by the Entity, if health is tracked.

Specified by:

getOriginalFinalDamage in interface AttackEntityEvent

Returns:

The final amount of damage to originally deal

getOriginalDamages

public final Map<DamageModifier,Double> getOriginalDamages()

Description copied from interface: AttackEntityEvent

Gets an ImmutableMap of all original DamageModifiers and their associated "modified" damage. Note that ordering is not retained.

Specified by:

getOriginalDamages in interface AttackEntityEvent

Returns:

An immutable map of the original modified damages

getFinalOutputDamage

public final double getFinalOutputDamage()

Description copied from interface: AttackEntityEvent

Gets the final damage that will be passed into the proceeding AttackEntityEvent. The final damage is the end result of the AttackEntityEvent.getBaseOutputDamage() being applied in Function.apply(Object) available from all the Tuples of DamageModifier to Function in AttackEntityEvent.getOriginalFunctions().

Specified by:

getFinalOutputDamage in interface AttackEntityEvent

Returns:

The final damage to deal

isModifierApplicable

public final boolean isModifierApplicable(DamageModifier damageModifier)

Description copied from interface: AttackEntityEvent

Checks whether the provided DamageModifier is applicable to the current available DamageModifiers.

Specified by:

isModifierApplicable in interface AttackEntityEvent

Parameters:

damageModifier - The damage modifier to check

Returns:

True if the damage modifier is relevant to this event

getOutputDamage

public final double getOutputDamage(DamageModifier damageModifier)

Description copied from interface: AttackEntityEvent

Gets the damage for the provided DamageModifier. Providing that AttackEntityEvent.isModifierApplicable(DamageModifier) returns true, the cached "damage" for the DamageModifier is returned.

Specified by:

getOutputDamage in interface AttackEntityEvent

Parameters:

damageModifier - The damage modifier to get the damage for

Returns:

The modifier

setOutputDamage

public final void setOutputDamage(DamageModifier damageModifier,
                                  DoubleUnaryOperator function)

Description copied from interface: AttackEntityEvent

Sets the provided Function to be used for the given DamageModifier. If the DamageModifier is already included in AttackEntityEvent.getModifiers(), the Function replaces the existing function. If there is no Tuple for the DamageModifier, a new one is created and added to the end of the list of Functions to be applied to the AttackEntityEvent.getBaseOutputDamage().

If needing to create a custom DamageModifier is required, usage of the DamageModifier.Builder is recommended.

Specified by:

setOutputDamage in interface AttackEntityEvent

Parameters:

damageModifier - The damage modifier

function - The function to map to the modifier

addDamageModifierBefore

public void addDamageModifierBefore(DamageModifier damageModifier,
                                    DoubleUnaryOperator function,
                                    Set<DamageModifierType> before)

Description copied from interface: AttackEntityEvent

Adds the provided DamageModifier and Function to the list of modifiers, such that the Set containing DamageModifierTypes provided in before will appear after the provided damage modifier.

Specified by:

addDamageModifierBefore in interface AttackEntityEvent

Parameters:

damageModifier - The damage modifier to add

function - The associated function

before - The set containing the modifier types to come after the provided modifier

addDamageModifierAfter

public void addDamageModifierAfter(DamageModifier damageModifier,
                                   DoubleUnaryOperator function,
                                   Set<DamageModifierType> after)

Description copied from interface: AttackEntityEvent

Adds the provided DamageModifier and Function to the list of modifiers, such that the modifier will appear in order after any current modifiers whose type are included in the provided Set of DamageModifierTypes.

Specified by:

addDamageModifierAfter in interface AttackEntityEvent

Parameters:

damageModifier - The damage modifier to add

function - The associated function

after - The set of modifier types to come before the new modifier

getBaseOutputDamage

public double getBaseOutputDamage()

Description copied from interface: AttackEntityEvent

Specified by:

getBaseOutputDamage in interface AttackEntityEvent

Returns:

The base damage

setBaseOutputDamage

public final void setBaseOutputDamage(double baseDamage)

Description copied from interface: AttackEntityEvent
