The @minecraft/server-ui module contains types for expressing simple dialog-based user experiences.

• ActionFormData contain a list of buttons with captions and images that can be used for presenting a set of options to a player.
• MessageFormData are simple two-button message experiences that are functional for Yes/No or OK/Cancel questions.
• ModalFormData allow for a more flexible "questionnaire-style" list of controls that can be used to take input.

Example

createActionForm.js

const form = new ActionFormData()
  .title("Months")
  .body("Choose your favorite month!")
  .button("January")
  .button("February")
  .button("March")
  .button("April")
  .button("May");

form.show(players[0]).then((response) => {
  if (response.selection === 3) {
    dimension.runCommand("say I like April too!");
  }
});
