ComfyUI Node: 📋 CR Simple Schedule

📋 CR Simple Schedule:

The CR Simple Schedule node is designed to facilitate the creation and management of animation schedules within the ComfyUI framework. This node allows you to define a sequence of keyframes and their corresponding values, which can be used to control various parameters over time. By providing a simple and intuitive way to input and manage schedules, the CR Simple Schedule node helps streamline the animation process, making it easier to achieve smooth and precise transitions. This node is particularly useful for AI artists who want to automate changes in their animations without delving into complex scripting or manual adjustments.

📋 CR Simple Schedule Input Parameters:

schedule

The schedule parameter is a string that contains the keyframe schedule. Each line in the schedule should represent a keyframe and its corresponding value, formatted as frame,value. This parameter is crucial as it defines the entire sequence of changes that will occur over time. The schedule should start at frame 0 to ensure proper execution. If the schedule is empty, the node will not perform any actions.

current_frame

The current_frame parameter is an integer that specifies the current frame of the animation. This parameter is used to determine which value from the schedule should be applied at the given frame. It is essential for synchronizing the schedule with the animation timeline. The value of current_frame should be a non-negative integer.

📋 CR Simple Schedule Output Parameters:

int_out

The int_out parameter is an integer output that represents the rounded-down value from the schedule for the current frame. This output is useful for scenarios where an integer value is required, such as frame-specific settings or discrete adjustments.

float_out

The float_out parameter is a floating-point output that represents the exact value from the schedule for the current frame. This output is beneficial for scenarios requiring precise control over parameters, such as smooth transitions or gradual changes.

show_help

The show_help parameter is a string containing a URL to the documentation for the CR Simple Schedule node. This output provides a quick reference for users who need additional information or guidance on using the node effectively.

📋 CR Simple Schedule Usage Tips:

• Ensure that your schedule starts at frame 0 to avoid any issues with missing keyframes at the beginning of the animation.
• Use clear and consistent formatting for your schedule entries to prevent errors and make the schedule easier to read and manage.
• Regularly check the current_frame parameter to ensure it aligns with your animation timeline, especially if you are making manual adjustments.

📋 CR Simple Schedule Common Errors and Solutions:

[Warning] CR Simple Value Scheduler. No lines in schedule

• Explanation: This warning indicates that the schedule parameter is empty, and no keyframes have been defined.
• Solution: Ensure that you provide a valid schedule string with keyframe entries formatted as frame,value.

[Warning] CR Simple Value Scheduler. No schedule found for frame. Simple schedules must start at frame 0.

• Explanation: This warning occurs when the schedule does not start at frame 0, leading to missing keyframes at the beginning of the animation.
• Solution: Modify your schedule to include an entry for frame 0 to ensure proper execution from the start.

[Warning] CR Simple Value Scheduler. Invalid params <params> at frame <current_frame>

• Explanation: This warning indicates that the value extracted from the schedule for the current frame is not a valid number.
• Solution: Check your schedule entries to ensure all values are correctly formatted as numbers and that there are no typos or invalid characters.
