Config Tabs

MyoConfigTab is the record used to describe a tab in the Myotus terminal settings UI.

What a config tab contains

• a title component
• either a texture blitter or an ItemStack icon
• a stylePath pointing to the active screen style JSON
• a MyoConfigTabScreen implementation used to build the tab UI
• a MyoConfigTabVisibility predicate used to decide whether the tab should render for the current terminal

Example

MyotusAPI.configRegistrar().registerTerminalConfigTab(new MyoConfigTab(
        Component.literal("Example"),
        Icon.COG,
        "example_terminal.json",
        new ExampleConfigScreen())
        .visibleWhen(context -> context.isItemHost()));

Icon options

MyoConfigTab supports multiple icon shapes:

• AE2 Icon
• Myotus MyoIcon
• plain ItemStack

Visibility helpers

1.21.1 adds a first-class visibility layer:

• MyoConfigTabVisibility.ALWAYS_VISIBLE
• MyoConfigTab.visibleWhen(...)
• MyoConfigTabContext.from(menu)

MyoConfigTabContext lets a visibility check inspect the current terminal host.

Useful helpers include:

• isItemHost()
• getHostItemStack()
• isHostItem(Item)
• isHostItem(ResourceLocation)
• isHostItemFrom(String namespace)

That means addon tabs can be shown only for specific portable terminals or host item families without manually duplicating host-inspection code in the UI layer.

Style path

The stylePath should point at the relevant screen style JSON. In the inspected source trees, Myotus itself registers a tab backed by:

assets/ae2/screens/config/myotus.json

What Myotus registers for itself

Both lines call MyotusConfigTab.initialize() during common setup and register the built-in terminal settings tab with:

• translated title text
• the Myotus icon set
• myotus.json as the style path
• MyotusConfigScreen as the screen implementation

Registrar helpers

IConfigRegistrar in 1.21.1 also adds fluent helpers:

• registerTerminalConfigTab(tab)
• registerTerminalConfigTabs(iterable)

Those helpers are not present in the older 1.20.1 line.
