@Name("Text Display Opacity")
@Description("Returns or changes the text opacity of <a href=\'#display\'>text displays</a>. The default is 255, fully opaque.\nValues are between 0 and 255. 0 to 3 are treated the same as 255, meaning fully opaque.\nValues from 4 to 26 are fully transparent, and opacity increases linearly from there up to 255.\nFor backwards compatability, setting negative values between -1 and -128 wrap around, so -1 is the same as 255 and -128 is the same as 128.\nAdding or subtracting values will adjust the opacity within the bounds of 0-255, so subtracting 300 wil always result in an opacity of 0.\n")
@Example("set the text opacity of the last spawned text display to 0 # fully opaque") @Example("set text opacity of all text displays to 255 # fully opaque") @Example("set text opacity of all text displays to 128 # semi-transparent") @Example("set text opacity of all text displays to 4 # fully transparent")

ExprTextDisplayOpacity

public ExprTextDisplayOpacity()

Method Details

convert

@Nullable
public @Nullable Integer convert(org.bukkit.entity.Display display)

Description copied from interface: Converter

Converts an object using this Converter.

Specified by:

convert in interface Converter<org.bukkit.entity.Display,Integer>

Specified by:

convert in class ch.njol.skript.expressions.base.SimplePropertyExpression<org.bukkit.entity.Display,Integer>

Parameters:

display - The object to convert.

Returns:

The converted object.

acceptChange

public Class<?> @Nullable [] 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>

Parameters:

mode - The mode to check

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,
 Object @Nullable [] 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>

Parameters:

event - The event

delta - An array with one or more instances of one or more of 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.

mode - The Changer.ChangeMode of the attempted change

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 ch.njol.skript.expressions.base.SimplePropertyExpression<org.bukkit.entity.Display,Integer>
