How to create an array of objects for ticket prices in an event schema.

Yes, absolutely! You can create an array of inline objects without needing to reference separate documents. This is a common pattern in Sanity for exactly your use case - having a reusable structure (like price tiers) that you can selectively add to each event.

Here's how to set it up in your event schema:

defineField({
  name: 'prices',
  title: 'Prices',
  type: 'array',
  of: [
    defineArrayMember({
      name: 'priceOption',
      type: 'object',
      fields: [
        defineField({
          name: 'title',
          type: 'string',
          title: 'Price Title',
          description: 'e.g., "Early Bird", "General Admission", "VIP"'
        }),
        defineField({
          name: 'value',
          type: 'number',
          title: 'Price Value'
        })
      ],
      preview: {
        select: {
          title: 'title',
          value: 'value'
        },
        prepare({ title, value }) {
          return {
            title: title,
            subtitle: `$${value}`
          }
        }
      }
    })
  ]
})

This creates an array field with inline object members. Each price item will have its own title and value fields, and they'll be stored directly in the event document - no separate document types or references needed.

The preview configuration makes it nice to work with in the Studio by showing the title and formatted price. For each event, editors can add only the price options they need from the "Add item" menu, and they can reorder them via drag-and-drop.

The key here is using type: 'object' inside the defineArrayMember - this creates an inline object structure rather than a reference to another document.
