# Other narrative features (/start/other-narrative-features)



<Accordions>
  <Accordion title="managing_the_end_of_the_game" id="managing-the-end-of-the-game">
    When all `steps` of all `labels` are executed, the game will stop. The developer is responsible for handling the end of the game, as visual novels can have different ending strategies:

    * The game ends when all `steps` are executed.
    * The game has no end; if all steps are completed, another `label` will be started or the player will have to interact with an interface that can potentially start another `label`.
    * The game ends when the player reaches a specific point, such as due to game over.

    To manage the end of the game, set `Game.onEnd`. This function is called when the game ends and has the same signature as a `step`.

    For example, to end the game and navigate to an end screen:

    ```ts title="main.ts"
    import { Game } from "@drincs/pixi-vn";

    Game.onEnd(async (props) => {
        props.navigate("/end");
    });
    ```

    If your game has no end and should restart or loop:

    ```ts title="content/labels/start.label.ts"
    export const startLabel = newLabel("start_label_id", () => {
        return [
            // ...
        ];
    });
    ```

    ```ts title="main.ts"
    import { Game } from "@drincs/pixi-vn";

    Game.onEnd(async (props) => {
        narration.call(startLabel, props);
    });
    ```
  </Accordion>

  <Accordion title="random_number_generation" id="random-number-generation">
    Pixi’VN includes a built-in function to generate random numbers. Use `narration.getRandomNumber()` with the following parameters:

    * `min`: The minimum value.
    * `max`: The maximum value.
    * `options` (Optional):
      * `onceonly`: If `true`, the number will be generated only once for the current `step` of the `label` (default: `false`). Note: `min` and `max` affect the storage of already generated numbers.
  </Accordion>

  <Accordion title="check_if_the_label_has_already_been_completed" id="check-if-the-label-has-already-been-completed">
    To check if a `label` has already been completed, use the `narration.isLabelAlreadyCompleted` function.
    This function has the following parameters:

    * `label`: The <DynamicLink href="/start/labels">`label`</DynamicLink> to check.

    ```typescript
    const isLabelCompleted = narration.isLabelAlreadyCompleted(startLabel);
    const isLabelCompleted = narration.isLabelAlreadyCompleted("labelid");
    ```
  </Accordion>

  <Accordion title="check_if_current_step_is_already_been_opened" id="check-if-current-step-is-already-been-opened">
    To check if the current `step` has already been opened, use `narration.isCurrentStepAlreadyOpened`.

    ```typescript
    const isCurrentStepOpened = narration.isCurrentStepAlreadyOpened;
    ```
  </Accordion>

  <Accordion title="counter_of_execution_times_of_the_current_step" id="counter-of-execution-times-of-the-current-step">
    To get the execution count for the current `step`, use `narration.currentStepTimesCounter`. &#x2A;*Important:** The counter is only incremented if `narration.currentStepTimesCounter` is executed.

    ```ts title="content/labels/start.label.ts"
    export const label = newLabel("id", () => {
        if (narration.currentStepTimesCounter === 0) {
            // ✅ will be incremented
            // ...
        } else {
            // ...
        }
    });
    ```

    ```ts title="content/labels/start.label.ts"
    export const label = newLabel("id", () => {
        if (narration.currentStepTimesCounter === 0) {
            // ✅ will be incremented
            // ...
        } else if (narration.currentStepTimesCounter === 1) {
            // ✅ Not incremented again in this step
            // ...
        }
    });
    ```

    ```ts title="content/labels/start.label.ts"
    export const label = newLabel("id", () => {
        if (flag) {
            if (narration.currentStepTimesCounter === 1) {
                // ❌ Only incremented if "flag" is true
                // ...
            }
        }
    });
    ```

    To reset the execution counter for the current `step`, set `narration.currentStepTimesCounter = 0`.

    ```typescript
    narration.currentStepTimesCounter = 0;
    ```
