I want to change the curve property of

particleSystem.main.startLifetime

If I write

particleSystem.main.startLifetime = new ParticleSystem.MinMaxCurve();

it says

Cannot modify the return value of 'ParticleSystem.main' because it is not a variable

If I try this

particleSystem.main.startLifetime.curve = minCurve;

it says

Cannot modify the return value of 'ParticleSystem.MainModule.startLifetime' because it is not a variable

And if I try to change the curve directly

    foreach (var key in minCurve.keys)
    {
        Debug.Log("adding a key");
        particleSystem.main.startLifetime.curve.AddKey(key);
        Debug.Log("length: " + particleSystem.main.startLifetime.curve.keys.Length);
    }

It doesn't change the curve at all. The Length is the same, and in the window the curve doesn't change too.

So what do I do wrong?

Have you taken a look at this thread ? https://forum.unity3d.com/threads/cant-set-any-new-particle-system-properties-through-script.358964/ – Hellium Feb 23 '17 at 16:46
Yeah, particleSystem.startLifetime returns only float value and marked as deprecated – user2686299 Feb 23 '17 at 16:48
Check the duplicated question. Let me know if there is a question. – Programmer Feb 23 '17 at 16:49
Okay, I can change curves of properties that aren't in the main module of ParticleSystem. But ParticleSystem.main.startLifetime is still unchangeable. Though I can get its value. – user2686299 Feb 23 '17 at 17:27
oh I see, at first i must main module, thanx – user2686299 Feb 23 '17 at 17:33
