Menu Path : Operator > Math > Arithmetic > Lerp
The Lerp Operator calculates the linear interpolation of a value between two border values.
This Operator accepts input values of various types. For the list of types this Operator can use, see Available Types. The X and Y input are always of the same type. The S input is either a float or a vector of the same size as X and Y. If S is between 0 and 1 then the result is between X and Y.
Operator properties
| Input | Type | Description |
|---|---|---|
| X | Configurable | The value to interpolate from. |
| Y | Configurable | The value to interpolate to. |
| S | Configurable | A value for the interpolation. |
| Output | Type | Description |
|---|---|---|
| Out | Dependent | The linear interpolation of S between X and Y. The Type changes to match the type of X and Y. |
Operator configuration
To view the Operator’s configuration, click the cog icon in the Operator’s header. X and Y must be the same type among Available Types. If S is a vector type, Unity calculates the interpolation value by value.
Available types
You can use the following types for your input ports:
- float
- Vector
- Vector2
- Vector3
- Vector4
- Position
- Direction
