Conditional Icons

Conditional icons are an additional property of main icons,
aimed at more standardized implementation of "displaying icons and executing actions under certain conditions"

The configuration of conditional sub-icons is done under the root node of the main icon

Node	Aliases	Description
sub	icons	Sub-icon list

Sub-icon Properties

In addition to the properties that regular icons have, sub-icons also have additional properties as follows:

Node	Aliases	Accepted Values	Description
condition	if, rule	String	Display condition
inherit	-	Bool	Whether to inherit parent icon properties

• condition is an essential Kether conditional expression for sub-icons
• inherit is enabled by default, reducing some repetitive configuration

'myCustomIcon':
  material: apple
  name: 'Apple'
  sub:
    if: player op
    material: diamond
    name: 'Diamond'
    action: tell Hello

In this example with only one sub-icon, the condition is judged when the icon is first rendered

If player op is satisfied, i.e., the player is an OP administrator, then display an icon with diamond material,
and support executing the action tell Hello when interacted with

If the condition is not satisfied, then display the default icon with apple material

Multi-level Sub-icons

Similarly, write in the sub-icon node, just write each sub-icon in List format

rank:
  material: stone
  name: 'Unranked'
  sub:
    - rule: perm "group.vip+"
      material: emerald
      name: 'VIP+'
    - rule: perm "group.vip"
      material: diamond
      name: 'VIP'

The judgment order in this example is from front to back, i.e., first judge VIP+, then judge VIP
If neither condition is satisfied, then display the default Unranked
