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.
|Direction||Vec2||The origin vector to calculate the reflection vector for.|
|Normal||Vec2||The normal vector of the reflection surface.|
|Result||Vec2||The reflection vector of A.|
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.
