Here’s the 2D particle system that I ported to MonoGame. I did minimal changes to the original
Here’s a 3D particle system from the XNA community. This is more advanced because it uses HLSL to animate the particles. I tried to port it to MonoGame but for some unknown reason the particles aren’t displayed (they’re displayed in the original project using XNA) but I don’t know how HLSL work so I gave up (for now). It’s a DrawableGameComponent too.
I Hope this help!
