Important parts to read: the first two sections of instructions and the second part of notes and credits. The rest you can read if you want. I recommend the bottom of the instructions. It's some cool presets. Read the second to last part of the instructions to read about the superiority of pen. Move your mouse to the top of the screen to show options. Adjust the variable then click the flag so it can take effect. You can use this if you have an atmospheric game you'd like to improve (that means @2030). Works best with bitmap because pen "Why pen?" you might ask. Well, you can have a lot more particles. For cloning you can only have up to 300, while with pen you can have unlimited (but it will lag then crash, so maybe not...). But seriously? It works just fine at 3,000 particles. That's 10 times the clone limit. Cool presets: Particles 5,000, Size 2, Base Transparency 190. It's snow! Particles 50, Size 4, Base Transparency 255. It's fireflies! NOTE: For this one, decrease the blue in RGB to give a nice firefly yellow. Particles 5,000, Size 4, Base Transparency 225. It's a blizzard! DEFAULT VALUES. Dusty ambiance. Particles 200, Size 4, Base Transparency 150. It's @griffpatch's dust project!
I was inspired by Limbo. The black-and-white graphics could be replicated easily with scratch, but it has so much more. Gaussian blurs, white noise, dynamic depth of field, and anything else you could want. I thought it would be cool to really stretch the bounds of scratch and make something amazing. I'm still working on that dynamic Gaussian blur and white noise, though. This is a start. The number of particles you should use depends on what effect you want. If you're going for just a few particles drifting around lazily, go for 350 to 1500. If you want a more fog type, go from 3500 to 4500. Anything higher than that will just lag to much. It's only an option for fun XD. If there's any other effect you want, just figure it out... Also, for more defined particles, set the base transparency to 100-130. Higher and you've got snow. Soon I might try to add a scrolling system, maybe a system for the z position of the particle, and more super complicated maths.
