I am using trapcode particular to animate the foam blast or foam arc of an fire extinguisher. The foam needs to hit specific point. At the moment I am trying to do so by animating the angle or position of the emitter. It is a very tidious method. Gravitation and the time delay of the particles make it hard to hit the right spots.
Is there a way to animate or control the destination point of the particles? Something like an attractor? The path function in physics looked promising but you cannot animate the path.
I am happy to explain it a bit more if I haven't discribed it well enough.
You can use the Radial field with a strong negative value and animate its position to attract your particles. The only problem is that it will accelerate them, so you may need to add a lot of Air Resistance to slow them down again. Beyond that I don't really see a way. If you want to give it a try and it's feasible, you can also time-reverse your project - emit the particles from the end based on a layer/ layer grid emitter, then have them sucked in by a black hole (aka your Radial field). Time-reverse and it will look like it's spitting out the particles. Beyond that this is once again an example of things that can be done much easier in a 3D program.
