How do I get a particle system up and running in 4.9 (c++)

Hello, I am currently trying to get a particle system up and running in c++. The logic is that whenever a person is set on fire, they play a combustion particle effect. I tried looking up some stuff up, but things like TSubobjectPtr MyParticleSystem; only works pre-4.9, and I can’t find anything on how it works in 4.9.

Any help would be appreciated.
