# Scale

### What It Does

The Scale Vector2 node multiplies a 2D vector by a scalar value, changing its length while preserving its direction. It's useful for resizing vectors or adjusting their magnitude.

### Inputs

| Name   | Description               | Type    | Required |
| ------ | ------------------------- | ------- | -------- |
| Vector | The 2D vector to scale    | Vector2 | Yes      |
| Scalar | The multiplication factor | Number  | No       |

### Outputs

| Name  | Description       | Type    |
| ----- | ----------------- | ------- |
| Value | The scaled vector | Vector2 |

### How to Use It

1. Drag the Scale Vector2 node into your graph.
2. Connect a 2D vector (like `[10, 20]`) to the "Vector" input.
3. Set the "Scalar" input to your desired scale factor (like `0.5` or `2`) or use the default (`1`).
4. The output will be a vector with each component multiplied by the scalar (e.g., `[5, 10]` or `[20, 40]`).

### Tips

* A scalar value of 1 leaves the vector unchanged.
* Negative scalar values reverse the vector's direction.
* Combine with Normalize to create vectors of exact length.
