Class SimpleOption<T>

java.lang.Object

net.minecraft.client.option.SimpleOption<T>

@Environment(CLIENT)
public final class SimpleOption<T>
extends Object

A class representing an option of a client. Exactly one instance of this class should be created per option. See below for how to create an instance.

Option values

This class allows querying and storing of the option value via getValue() and setValue(Object) respectively. Option values are automatically validated, and if the value is invalid, the value resets back to the default. Some validators will coerce the invalid value (e.g. by clamping) into a valid one instead of failing; in this case the new value is used.

Option values are serialized using codecs. Check DataFixerUpper code for the list of available codecs. For serialization of enums, you can check the code in GameOptions.

If the value has changed, the changeCallback passed to the constructor will trigger with the new value.

Callbacks

This class itself cannot be extended by default; instead, the behavior of the option, such as validation or rendering of the ClickableWidget associated with the option, is customized by passing a SimpleOption.Callbacks instance. There are several existing callbacks that should cover most of the needs:

• SimpleOption.PotentialValuesBasedCallbacks: The most simple cycling option. Useful for enums.
• SimpleOption.AlternateValuesSupportingCyclingCallbacks: An option with alternate potential values that are used only when certain conditions are met. This is used in vanilla to hide "Fabulous!" graphics option after the user cancelled the warning.
• SimpleOption.LazyCyclingCallbacks: An option whose potential values are determined lazily.
• SimpleOption.MaxSuppliableIntCallbacks: A cycling option with an integer value that has a fixed minimum value and a dynamic maximum value. Values outside the range are clamped. This is used in vanilla to implement the GUI Scale option.
• SimpleOption.DoubleSliderCallbacks: A slider option of a double between 0.0 and 1.0. Values outside this range are considered invalid.
• SimpleOption.ValidatingIntSliderCallbacks: A slider option of an int with a minimum and maximum values. Values outside this range are considered invalid.

See also several ofBoolean methods for options using boolean values.

Modifiers

Slider option callbacks allow "modifiers" to be applied. The "slider progress value" is the value used to calculate the slider's progress and must be linear. The real value, simply called "value" in withModifier methods, is the value used in getValue() and passed to textGetter.

Text

Options themselves have names; the translation key of the option needs to be passed when constructing this class. This corresponds to text. Options also have the rendered text, composed of the option name and the value; the code obtains the value using the valueTextGetter in the constructor. The getter takes the option's name and the current value, and returns the text. Several static methods in GameOptions can be used to format the name and the value. For options backed by an enum that implements TranslatableOption, enumValueText() can be passed to valueTextGetter to obtain the rendered text from the enum. Options can also have a tooltip, specified by passing tooltipFactoryGetter. If the option has no tooltips, you can pass emptyTooltip(), and if the option always uses one tooltip, you can pass constantTooltip(Text).
