The LerpTo method is used to interpolate between the current color and a target color. This method modifies the current color by moving it towards the target color by a specified fraction. The interpolation can be clamped to ensure the resulting color components remain within valid bounds.
To use the LerpTo method, you need to have an instance of the Color struct. Call the method on this instance, passing in the target color, the fraction of interpolation, and a boolean indicating whether to clamp the result.
The frac parameter should be a value between 0 and 1, where 0 results in no change and 1 results in the color being set to the target color. The clamp parameter, when set to true, ensures that the resulting color components do not exceed the range of 0 to 1.
// Example of using LerpTo method Color currentColor = new Color(0.5f, 0.5f, 0.5f, 1.0f); // A gray color Color targetColor = Color.Red; // Target color is red float fraction = 0.25f; // Interpolate 25% towards the target color bool clamp = true; // Clamp the result to ensure valid color range // Interpolate the current color towards the target color currentColor.LerpTo(ref targetColor, fraction, clamp); // currentColor is now a color 25% closer to red
