Particle Playground - Change Lifetime Color

/* To change the lifetime color’s gradient through script you can assign a new gradient onto the lifetimeColor variable as such: */

using UnityEngine;
using System.Collections;
using ParticlePlayground;

public class ChangeLifetimeGradient : MonoBehaviour {

    public PlaygroundParticlesC particles;
    public Gradient newGradient;

    void Start () {
        particles.lifetimeColor = newGradient;
    }
}

/* Would you like to only change a particular part of the gradient you can reach into the gradient’s keys and set a new color, here’s how you can change the end color of a gradient: */

using UnityEngine;
using System.Collections;
using ParticlePlayground;

public class ChangeLifetimeGradient : MonoBehaviour {

    public PlaygroundParticlesC particles;
    public Color newEndColor;

    void Start () {

        // Get the color- and alpha keys of the current lifetime gradient
        GradientColorKey[] newLifetimeColorKeys = (GradientColorKey[])particles.lifetimeColor.colorKeys.Clone();
        GradientAlphaKey[] newLifetimeAlphaKeys = (GradientAlphaKey[])particles.lifetimeColor.alphaKeys.Clone();

        // Apply the new end color
        newLifetimeColorKeys[newLifetimeColorKeys.Length-1].color = newEndColor;

        // Set the color- and alpha keys back into the lifetime gradient
        particles.lifetimeColor.SetKeys(newLifetimeColorKeys, newLifetimeAlphaKeys);
    }
}
