Item icon

system:item

Renders the item snapshot in the context and shows the item tooltip on hover.

Nodes are written into the body or children of a resource pack card template. Besides their own fields, all nodes share id, style, when, unless and repeat; see Common node fields.

JSON example

{
  "type": "system:item",
  "item": "{{reward_item}}",

Placed in the body of a card template or the children of a container. Placeholders come from server snapshots and client build events; changing only the JSON does not produce the missing data or business handlers.
