For an animation I'm creating, I need to have the ability to launch particles out of a moving emitter object every N seconds, starting and ending at a certain moment. The particles need to procedurally bounce off walls. They would also need to have visual trails and create a visual effect wherever they hit.
I managed an "Ok" result using a regular particle system, with a Particle Instance Object that itself emits particles (=trails), and its built-in physics, as well as using a Motion blur on top to blend between the particles. However, I still lack the ability to detect hits; and am interested in how the same can be achieved using GN.
My current progress:
I'm able to emit a particle from an object (different from the one that has the GN modifier), that is able to move independently from the particle emitted. The particle bounces as well. Here is the setup:
I plan to use the Raycast node's "Hit position" output to create instances of hit VFX, and some kind of Join geometry/simulation setup for the trails. However, I still can't figure out how to more than one particle and over a period of time (i.e. a particle launched every X frames).
Any input (including totally different ways of achieving this) is welcome!
