[Solved] Can't change ParticleSystem startSize

I've been across 3-5 different Unity Docs and Scripting API pages, and I'm pretty sure I'm doing this correctly, but I'm getting an error.

'ParticleSystem' does not contain a definition for 'mainModule' and no accessible extension method 'mainModule' accepting a first argument of type 'ParticleSystem' could be found

Code (CSharp):

1. public GameObject explosionPrefab;
2. public ParticleSystem.MainModule mainModule;
3.  
4. void Update() {
5.  
6.     GameObject explosionParticles = Instantiate(explosionPrefab, transform.position, Quaternion.identity);
7.     mainModule = explosionParticles.GetComponent<ParticleSystem>().main;
8.     explosionParticles.GetComponent<ParticleSystem>().mainModule.startSize = fragmentSize;
9. }

The error is pointing to the last line (8).

 

In line 7 you are already getting the mainModule to a temporary variable (a necessary step).

In line 8 use that variable to access .startSize.

 

Thank you! It works.
