💖 fluidballs(6x) — XScreenSaver manual 💖

okay bestie, welcome to the XScreenSaver manual — this is the page for fluidballs(6x), and yes, we're about to talk about bouncing balls with main character energy. 🫶

🌸 NAME 🌸

fluidballs — literally the physics of bouncing balls. That's the whole name. 💖

✨ SYNOPSIS ✨

here's the exact summoning spell, no cap:

fluidballs [--display host:display.screen] [--visual visual] [--window]
       [--root] [--window-id number] [--count number] [--size number]
       [--gravity number] [--wind number] [--elasticity number] [--delay
       number] [--nonrandom] [--no-shake] [--fps]

🦋 DESCRIPTION 🦋

So this one models the physics of bouncing balls — or, depending on the settings, it can model particles in a gas or fluid. Same vibe, different physics era. If "Shake Box" is selected, then every now and then the box will be rotated, changing which direction is down — all in order to keep the settled balls in motion. Iconic behavior, honestly. periodt. 💅

💅 OPTIONS 💅

okay bestie, here's the full flag buffet. Every one of these is real, and I'm not summarizing a single one:

• --visual visual — Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. slay.
• --window — Draw on a newly-created window. This is the default.
• --root — Draw on the root window.
• --window-id number — Draw on the specified window.
• --count number — How many balls to display. Default: 300.
• --size number — Maximum size of each ball. Default: 25.
• --gravity number — Coefficient of gravity. Useful values are < 0.1. Default: 0.01.
• --wind number — Wind. Useful values are < 0.1. Default: 0.00.
• --elasticity number — Coefficient of elasticity. Useful values are 0.2 to 1.0. Default: 0.97. Lower numbers make less bouncy balls.
• --delay number — Per-frame delay, in microseconds. Default: 10000 (the page says 0.01 seconds. — yes, period included 🫶).
• --nonrandom — Make all balls be the same size.
• --no-nonrandom — Make the balls be random sizes. This is the default.
• --shake | --no-shake — Whether to shake the box if the system seems to have settled down. "Shake" means "change the direction of Down." Capital-D Down, iykyk. 👀
• --fps — Display the current frame rate and CPU load.

🌈 ENVIRONMENT 🌈

• DISPLAY — to get the default host and display number.
• XENVIRONMENT — to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
• XSCREENSAVER_WINDOW — The window ID to use with --root.

okay that's the whole page, bestie — go make those balls bounce. This was X Version 11, version 6.09 (07-Jun-2024), for fluidballs(6x) 💅✨🫶
