just use a live editor for particle json generating…
like this one: https://koreezgames.github.io/phaser3-particle-editor/
this editor can’t use customized texture, so I use the built-in texture to make what I want, and later modify the exported json to use my own texture
I did have a play with that, I found it a little frustrating to use.
I think I’ll make a modified version of that editor since most of my
particle effects will be moving so to speak.
