@Name("Age of Block/Entity")
@Description({"Returns the age or maximum age of blocks and age for entities (there in no maximum age for entities).","For blocks, \'Age\' represents the different growth stages that a crop-like block can go through. A value of 0 indicates that the crop was freshly planted, whilst a value equal to \'maximum age\' indicates that the crop is ripe and ready to be harvested.","For entities, \'Age\' represents the time left for them to become adults and it\'s in minus increasing to be 0 which means they\'re adults, e.g. A baby cow needs 20 minutes to become an adult which equals to 24,000 ticks so their age will be -24000 once spawned."})
@Examples({"# Set targeted crop to fully grown crop","set age of targeted block to maximum age of targeted block"," ","# Spawn a baby cow that will only need 1 minute to become an adult","spawn a baby cow at player","set age of last spawned entity to -1200 # in ticks = 60 seconds"})

Method Details

init

public boolean init(Expression<?>[] exprs,
 int matchedPattern,
 Kleenean isDelayed,
 SkriptParser.ParseResult parseResult)

Description copied from interface: SyntaxElement

Called just after the constructor.

Specified by:

init in interface SyntaxElement

Overrides:

init in class SimplePropertyExpression<Object,Integer>

Parameters:

exprs - all %expr%s included in the matching pattern in the order they appear in the pattern. If an optional value was left out it will still be included in this list holding the default value of the desired type which usually depends on the event.

matchedPattern - The index of the pattern which matched

isDelayed - Whether this expression is used after a delay or not (i.e. if the event has already passed when this expression will be called)

parseResult - Additional information about the match.

Returns:

Whether this expression was initialised successfully. An error should be printed prior to returning false to specify the cause.

• ParserInstance.isCurrentEvent(Class...)

convert

public @Nullable Integer convert(Object obj)

Description copied from interface: Converter

Converts an object from the given to the desired type.

Specified by:

convert in interface Converter<Object,Integer>

Specified by:

convert in class SimplePropertyExpression<Object,Integer>

Parameters:

obj - The object to convert.

Returns:

the converted object

acceptChange

public @Nullable Class<?>[] acceptChange(Changer.ChangeMode mode)

Description copied from interface: Expression

Tests whether this expression supports the given mode, and if yes what type it expects the delta to be.

Use Changer.ChangerUtils.acceptsChange(Expression, ChangeMode, Class...) to test whether an expression supports changing, don't directly use this method!

Please note that if a changer is registered for this expression's returnType this method does not have to be overridden. If you override it though make sure to return super.acceptChange(mode), and to handle the appropriate ChangeMode(s) in Expression.change(Event, Object[], ChangeMode) with super.change(...).

Unlike Changer.acceptChange(ChangeMode) this method may print errors.

Specified by:

acceptChange in interface Expression<Integer>

Overrides:

acceptChange in class SimpleExpression<Integer>

Returns:

An array of types that Expression.change(Event, Object[], ChangeMode) accepts as its delta parameter (which can be arrays to denote that multiple of that type are accepted), or null if the given mode is not supported. For Changer.ChangeMode.DELETE and Changer.ChangeMode.RESET this can return any non-null array to mark them as supported.

change

public void change(org.bukkit.event.Event event,
 @Nullable Object[] delta,
 Changer.ChangeMode mode)

Description copied from interface: Expression

Changes the expression's value by the given amount. This will only be called on supported modes and with the desired delta type as returned by Expression.acceptChange(ChangeMode)

Specified by:

change in interface Expression<Integer>

Overrides:

change in class SimpleExpression<Integer>

delta - An array with one or more instances of one or more of the the classes returned by Expression.acceptChange(ChangeMode) for the given change mode (null for Changer.ChangeMode.DELETE and Changer.ChangeMode.RESET). This can be a Object[], thus casting is not allowed.

getReturnType

public Class<? extends Integer> getReturnType()

Description copied from interface: Expression

Gets the return type of this expression.

Returns:

A supertype of any objects returned by Expression.getSingle(Event) and the component type of any arrays returned by Expression.getArray(Event)

getPropertyName

protected String getPropertyName()

Specified by:

getPropertyName in class SimplePropertyExpression<Object,Integer>
