Clamp
What It Does
Restricts a value to stay within a specified minimum and maximum range. If the value is below the minimum, it returns the minimum; if it's above the maximum, it returns the maximum; otherwise, it returns the original value.
Inputs
| Name | Description | Type | Required |
|---|---|---|---|
| value | The number to clamp | Number | No |
| min | The lower boundary | Number | No |
| max | The upper boundary | Number | No |
Outputs
| Name | Description | Type |
|---|---|---|
| value | The clamped result | Number |
How to Use It
- Drag the Clamp node into your graph.
- Set "value" to the number you want to restrict (e.g., 12).
- Set "min" to the lower bound (e.g., 5).
- Set "max" to the upper bound (e.g., 10).
- Run the graph—with the example values, your output will be 10 (since 12 exceeds the max).
Tips
- Make sure min is less than max, or the clamp will always return the min value.
- Clamp is useful for ensuring values stay within valid ranges before passing to other nodes.
- For colors and other non-numeric values, use specialized constraint nodes instead.

Use Cases
- Boundary Enforcement: Ensure values stay within acceptable limits.
- Input Validation: Sanitize user inputs to prevent extreme values.
- Responsive Sizing: Limit element sizes between minimum and maximum constraints.
- Animation Control: Prevent objects from moving outside defined areas.
