[Solved] How to only turn off new particles?

I have a ship that produces particles as an exhaust trail, and I want the exhaust to stop producing new particles when a certain condition is met, but I don't want to outright stop the particle system, because that would instantly turn off all current particles as well.

Can only find threads and questions regarding turning particle system on/off.

 

You can adjust the rate over time value of the

emission

module of your ParticleSystem.

It's common to have two separate values that correspond with OFF and MAX, and then according to your throttle setting, just adjust this value and set it into the rate over time.

The emission module is actually a struct, so you have to copy it out of the ParticleSystem before you modify any properties on it.

 

Thanks, that explains all the errors I was getting, didn't know about it being a struct.

 

You just call stop with the stop behavior parameter.

Thanks, didn't know about that one.

But in this case i'll stick with changing the emission rate, since I can do extra stuff for when things like the fuel level change.
