Struggling to get my head around the [LibGDX] Particles Editor

First of all, let me just say: if there is a better (i.e. easier) way to do particles than using the libGDX editor and engine in Java then I’d be happy to hear about it.

I’m fairly sure I get the basic concept of particles and how to use them in libGDX using the built in particles engine. I have a few examples of successfully rendering particles - albeit using the particles that others have created online.

However, trying to create my own particle effects using the editor is stumping me. Up till now, I’ve been told “just play around and see what everything does” and I have tried that. The problem is that I’m not really any the wiser… If I were to get anything like what I wanted it would be more by luck than judgement and not something I’ve achieved thus far.

I don’t know if it’s relevant since it’s my general ability to use the tool that’s lacking, but I’m currently trying to get some small red particles (blood) to splash upwards and then fall to the floor - an effect for when a character dies. In the past I have also tried (and failed )to create a shower of sparks which would be a similar effect except, obviously, using sparks instead of blood.

Anyone who is able to clearly explain how to use this complicated looking tool or explain another approach entirely that I can actually use would earn my undying and eternal gratitude.
