To achieve a smooth transition of additive transparency in Spine, you can use Unity's capabilities to interpolate values over time. Since the "Light Affects Additive" option is binary, you can manually adjust the transparency by interpolating the color values of the light over time. You can write a script in Unity that gradually changes the alpha value of the light's color based on the game's duration. Here's a basic example of how you might implement this:
using UnityEngine;
public class LightTransparencyController : MonoBehaviour {
public Color startColor;
public Color endColor;
public float duration;
private float currentTime;
void Update() {
currentTime += Time.deltaTime;
float percent = Mathf.Min(currentTime / duration, 1);
Color currentColor = Color.Lerp(startColor, endColor, percent);
// Apply currentColor to your light or material
}
}
This script interpolates between startColor
and endColor
over the specified duration
. You can adjust the startColor
and endColor
to control the transparency levels. Apply the currentColor
to your light or material to achieve the desired effect.
