Fixed in 5.3.2

Issue ID




ParticleSystem.IsAlive() always returns True for particle systems with longer duration

Visual Effects - Legacy


Steps to reproduce:

1. Open attached project
2. Open and play 'TestScene'
3. Notice the labels in top left of the game view, the red particle system IsAlive always returns true

The only thing different in two particle systems in the scene is their duration: Red one is 3. green - 2.

Reproduced with: 5.3.1f1
Not reproduced with: 5.3.0f4, 5.4.0b1

    Still have issues with the isAlive method returning true when it shouldn't in Unity 5.3.3f1.

    When I swicth the renderer's Render Mode, a PartileSystem obj's isAlive() in Stretched Billboard Mode will return false,other Render Mode allways return true.

    The workaround I made here was a timer script to disable particles.

    Can unity devs actually test things before calling them "fixed"? Different people reported it was buggy in *4* different patch releases before 5.3.2, this should have been fixed.
