Hello! I'm a new Playdate developer and long-time game dev that came from unity and missed using its particle system. So I'm making this!

Particle Sizzler is a lightweight standalone software that generates Spritesheets of particle simulations using Unity's Particle System as a base. Since you will end-up with a pre-baked spritesheet animation, it's obvious that they won't be able to dynamically generate when using on the Playdate (or anywhere else). So the best use cases are for static/one-shot particles like fire, explosions, thrusters, etc… And more often than not, need some tweaking in a proper image editor software like Aseprite.

I started making this for me, but maybe the community might appreciate it as well!

How to Use?

Just tweak the parameters and go crazy!

How to Export Spritesheet?

Press Render and wait for it to finish, then, press Export. Ta-da!

The Playdate Export option exports spritesheet with naming convention ready to be used in a 'ImageTable':  {name}-table-{width}-{height}.png

----------------------------------------------

Known Issues

• Gizmos do not correctly scale with image size
• Non-square ratio (1:1) images may not be able to be completely seen on the preview (ex: 12p x 200p)
• If you find any more, let me know!

I'd love to hear your thoughts! Do you have any requests?

Keep in mind that I am a solo developer and bugs might appear, let me know if you spot any!

The software is free to keep and use. But if you like it and would like to support what I do, feel free to donate! 

(Fun fact: The "Operating System" in which the simulation runs is from one of the games I'm making ;)

I'm in no way, shape or form affiliated with Unity or Panic.

Games that use Particle Sizzler

None so far, but if you are a dev and made something that uses it, let me know and I'll add you here!
