# Rotate Node ## Description Rotates value of input **UV** around a reference point defined by input **Center** by the amount of input **Rotation**. The unit for rotation angle can be selected by the parameter **Unit**. ## Ports | Name | Direction | Type | Binding | Description | |:------------ |:-------------|:-----|:---|:---| | UV | Input | Vector 2 | UV | Input UV value | | Center | Input | Vector 2 | None | Center point to rotate around | | Rotation | Input | Float | None | Amount of rotation to apply | | Out | Output | Vector 2 | None | Output UV value | ## Controls | Name | Type | Options | Description | |:------------ |:-------------|:-----|:---| | Unit | Dropdown | Radians, Degrees | Switches the unit for input **Rotation** | ## Generated Code Example The following example code represents one possible outcome of this node per **Unit** mode. **Radians** ``` void Unity_Rotate_Radians_float(float2 UV, float2 Center, float Rotation, out float2 Out) { UV -= Center; float s = sin(Rotation); float c = cos(Rotation); float2x2 rMatrix = float2x2(c, -s, s, c); rMatrix *= 0.5; rMatrix += 0.5; rMatrix = rMatrix * 2 - 1; UV.xy = mul(UV.xy, rMatrix); UV += Center; Out = UV; } ``` **Degrees** ``` void Unity_Rotate_Degrees_float(float2 UV, float2 Center, float Rotation, out float2 Out) { Rotation = Rotation * (3.1415926f/180.0f); UV -= Center; float s = sin(Rotation); float c = cos(Rotation); float2x2 rMatrix = float2x2(c, -s, s, c); rMatrix *= 0.5; rMatrix += 0.5; rMatrix = rMatrix * 2 - 1; UV.xy = mul(UV.xy, rMatrix); UV += Center; Out = UV; } ```
