I was getting a headache making particles for my Streets of Rage 4 game. So instead of reaching for the paracetamol, I made this - particle studio.
It manipulates the particle variable on screen, in real time, allowing you to get a particle affect that you want and then it will output the source code to a file so you can copy and paste it.
It can also rotate the particles (drag the emission sphere) and position them in 3d.
Let me know what you think of the idea, and what you would like to see added to this editor.
The plan is to make it a free tool to developers, so the more suggestions the better
Here's the screenshot:
