Particles: Point Emitter in Ren'Py

You can:

• `sprite` - Use your own particle image. Any displayable.
• `count` - Change the particle count.
• `pos` - Move the particle origin source.
• `radius` - Set the radius for how far the particles move from the origin.
• `rotate` - Rotate the entire effect (degrees).
• `slice` - Set an angle (degrees) for the particles to generate in (e.g. full circle or slice).
• `speed' - Set the particle speed.
• `warmup_time` - Stagger the particles so there is a cooldown period between each one showing up (If you set it to 0 they will all come out simultaneously and "pulse").
