Use Reflect to get the reflection vector of an input vector on a surface. Supported types: Vec2 and Vec3. Reflect is in the Transform category.
Input
| Name | Data Type | Description |
|---|---|---|
| Direction | Vec2 | The origin vector to calculate the reflection vector for. |
| Normal | Vec2 | The normal vector of the reflection surface. |
Output
| Name | Data Type | Description |
|---|---|---|
| Result | Vec2 | The reflection vector of A. |
Example
This example has a checkerboard placeholder 2D object initialized to the center of the screen. It maintains a variable called “speed”, and initializes that with value (12, -1). It updates the speed value if the position of the checkerboard goes beyond the vertical boundary of the screen by using the Reflect node.
