I'm making a 2D top view game (same perspective as the game Forager) in Unity. I want the game to be visually appealing, and want to add some details like dust particles. Whenever the character moves, I want dust-like particles trailing behind the character, almost as if the character is kicking up dust.
So something like this:
The particles are a little big in Forager, but this is similar.
I've used Unity's trail renderer before, but I only used it for making a straight line, and not multiple random particles like this. What should I do to achieve this effect?
Just general guidelines would be okay. I don't necessarily need a complete code, just some guidance because I don't know how to start.
