Hi bro，

I need use actor to get particles position.

I declare actor in Class and use it in Update() function，like picture.

And i get errors，but only at the first in Update() loop，then it can run well without errors。

I wonder what is the reason and how can i fix it .

Hi there!

you're missing:


before the for loop. You can't access actor data unless it's loaded in the solver . See: http://obi.virtualmethodstudio.com/tutor...icles.html
let me know how it goes!
