I want to make it so that whenever an OSC message is received, I spawn one or more particles in a Niagara system. I was planning on at most using Blueprints for this, not C++ if I can avoid it.
I’ve found one way, by setting the probability to 0, and flipping it to 1 for a short while on receiving a message, but it’s not ideal, since it still needs to be at 1 for exactly one frame, or I will get either no particles triggered or too many, depending on how long I leave it flipped on to 1.
Is there a better way to achieve what I want, with more precision, so that each OSC message/keypress received is guaranteed to spawn n particles?
I’ve made some progress in my learning, and have come to the more explicit understanding that I need to map a “User Exposed” variable - float or bool - to an “Event Handler” which can spawn n variables in my particle system. Still unsure how those tow can be linked though.
When the variable changes it should somehow be interpreted as an event. Is that reasonable?
Edit:
An RTFM link is definitely appreciated too While experienced with graphics programming I am new to Unreal, so am not quite as good as I could be on finding information in the right places…
As a step sideways, I learned that I can spawn “projectiles” on events, but I would still love for each projectile to be part of a Niagara system rather than essentially re-invent it…
Bumping this:
Any tips on how I can control the triggering of each particle spawn individually?
