The Evaluate method of the Gradient struct is used to determine the color at a specific point in time along the gradient. This method interpolates between the defined color stops to return a Color that represents the gradient at the given time.
To use the Evaluate method, you need to have a Gradient object with defined color stops. You can then call Evaluate with a time parameter, which is a float value representing the position along the gradient (typically between 0.0 and 1.0). The method will return the interpolated Color at that position.
// Create a gradient with color stops var gradient = new Gradient(); gradient.AddColor(0.0f, new Color(1, 0, 0)); // Red at start gradient.AddColor(1.0f, new Color(0, 0, 1)); // Blue at end // Evaluate the color at the midpoint of the gradient time = 0.5f; Color colorAtMidpoint = gradient.Evaluate(time); // colorAtMidpoint should be a blend of red and blue, typically purple
