ComfyUI Node: 📑 CR Simple Value Scheduler

📑 CR Simple Value Scheduler:

The CR Simple Value Scheduler is designed to facilitate the scheduling of simple numerical values over a series of frames in an animation. This node is particularly useful for AI artists who need to automate the transition of values, such as opacity, scale, or other numerical parameters, across different frames in their projects. By defining a schedule, you can control how a value changes over time, ensuring smooth and precise animations. The node simplifies the process by allowing you to input a schedule in a straightforward format, making it accessible even if you don't have a technical background. The primary goal of this node is to provide an easy-to-use tool for managing value transitions, enhancing the efficiency and creativity of your animation workflow.

📑 CR Simple Value Scheduler Input Parameters:

schedule

The schedule parameter is a string that defines the value transitions over different frames. Each line in the schedule should specify a frame number and the corresponding value, separated by a space or a comma. This parameter is crucial as it dictates how the value will change over time. If the schedule is empty, the node will issue a warning and return no output. There are no specific minimum or maximum values for this parameter, but it should be formatted correctly to ensure proper execution.

current_frame

The current_frame parameter is an integer that indicates the current frame number for which the value needs to be scheduled. This parameter is essential as it determines the specific value to be output based on the provided schedule. The value of current_frame should be within the range of frames defined in the schedule to avoid warnings or errors.

📑 CR Simple Value Scheduler Output Parameters:

int_out

The int_out parameter is an integer output that represents the scheduled value for the current frame, rounded down to the nearest whole number. This output is useful for scenarios where an integer value is required, such as frame counts or discrete steps in an animation.

float_out

The float_out parameter is a floating-point output that represents the exact scheduled value for the current frame. This output is beneficial for applications requiring precise numerical values, such as opacity levels or scaling factors.

show_help

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

📑 CR Simple Value Scheduler Usage Tips:

• Ensure that your schedule parameter is correctly formatted with each frame and value pair on a new line to avoid parsing errors.
• Use the current_frame parameter to dynamically adjust the value based on the frame number, allowing for smooth transitions in your animations.
• Refer to the show_help URL for detailed examples and additional usage instructions to maximize the node's potential.

📑 CR Simple Value Scheduler Common Errors and Solutions:

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

• Explanation: This warning occurs when the schedule parameter is empty.
• Solution: Ensure that the schedule parameter contains valid frame and value pairs.

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

• Explanation: This warning indicates that the schedule does not include a value for the specified current_frame.
• Solution: Verify that your schedule includes entries for all relevant frames, starting from frame 0.

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

• Explanation: This warning is triggered when the value in the schedule cannot be parsed as a float.
• Solution: Check the schedule for any formatting errors or invalid values and correct them to ensure they can be interpreted as numerical values.
