     The base Affector does not alter any attributes, but can be used to emit a signal

-    Affectors have different performance characteristics to the other particle system elements. In particular,
-    they have some simplifications to try to maintain a simulation at real-time or faster. When running a system
-    with Affectors, irregular frame timings that grow too large ( > one second per frame) will cause the Affectors
-    to try and cut corners with a faster but less accurate simulation. If the system has multiple affectors the order
-    in which they are applied is not guaranteed, and when simulating larger time shifts they will simulate the whole
-    shift each, which can lead to different results compared to smaller time shifts.

-    Accurate simulation for large numbers of particles (hundreds) with multiple affectors may be possible on some hardware,
-    but on less capable hardware you should expect small irregularties in the simulation as simulates with worse granularity.
