How to set ParticleSystem.startRotation3D by code？

Questions & Answers

I try two ways to set ParticleSystem.startRotation3D in code

  1. [ParticleSystem].startRotation3D=new Vector3(45,0,0);

  2. [PartcileSystem.Particle].rotation3D=new Vector3(45,0,0);

Unless I tick the checkbox “3D Start Rotation” in inspector manually , they didn’t work!
But how can i set “3D Start Rotation” to true by code in Unity5.4.0?I can’t seem to find anything in the API for this.

To modify modules from a particle now you need to create a reference of the module:

var main = particleSystem.main;
main.startRotation3D = true;

The values of the start rotation are separated like startRotationX, startRotationY, startRotationZ, you can modify them the same way above.

var main = particleSystem.main;
main.startRotationX = 45;
main.startRotationY = 0;
main.startRotationZ = 0;
