# String Schedule 📅🅕🅝
## Documentation
- Class name: `StringSchedule`
- Category: `FizzNodes 📅🅕🅝/ScheduleNodes`
- Output node: `False`

The StringSchedule node is designed to manage and schedule string-based content for dynamic animation or content generation. It leverages scheduling settings to interpolate between different string values over a series of frames, facilitating the creation of animated text or evolving narratives.
## Input types
### Required
- **`text`**
    - This input takes a multiline string that represents the text to be scheduled and animated, serving as the primary content for the scheduling process.
    - Comfy dtype: `STRING`
    - Python dtype: `str`
- **`max_frames`**
    - Specifies the maximum number of frames for the scheduling, determining the length of the animation or content generation process.
    - Comfy dtype: `INT`
    - Python dtype: `int`
- **`current_frame`**
    - Indicates the current frame number in the scheduling process, used to calculate the specific string content to be displayed at any given frame.
    - Comfy dtype: `INT`
    - Python dtype: `int`
- **`print_output`**
    - A boolean flag that, when set to true, enables the printing of the scheduling process's output for debugging or tracking purposes.
    - Comfy dtype: `BOOLEAN`
    - Python dtype: `bool`
### Optional
- **`pre_text`**
    - An optional string input that is prepended to the main text before scheduling.
    - Comfy dtype: `STRING`
    - Python dtype: `str`
- **`app_text`**
    - An optional string input that is appended to the main text after scheduling.
    - Comfy dtype: `STRING`
    - Python dtype: `str`
- **`pw_a`**
    - A parameter weight used in the scheduling algorithm to adjust the influence of certain aspects of the text.
    - Comfy dtype: `FLOAT`
    - Python dtype: `float`
- **`pw_b`**
    - A parameter weight similar to pw_a, used for adjusting the scheduling algorithm's influence on the text.
    - Comfy dtype: `FLOAT`
    - Python dtype: `float`
- **`pw_c`**
    - Another parameter weight for fine-tuning the scheduling algorithm's effect on the text.
    - Comfy dtype: `FLOAT`
    - Python dtype: `float`
- **`pw_d`**
    - A parameter weight that works alongside pw_a, pw_b, and pw_c to customize the scheduling outcome.
    - Comfy dtype: `FLOAT`
    - Python dtype: `float`
## Output types
- **`POS`**
    - Comfy dtype: `STRING`
    - The output is a dynamically scheduled string, representing the positive aspect of the text adjusted according to the current frame and scheduling settings.
    - Python dtype: `str`
- **`NEG`**
    - Comfy dtype: `STRING`
    - The output is a dynamically scheduled string, representing the negative aspect of the text adjusted according to the current frame and scheduling settings.
    - Python dtype: `str`
## Usage tips
- Infra type: `CPU`
- Common nodes: unknown
