Quantum Client

# Quantum Client A sleek, lightweight Minecraft utility client for **Fabric 1.21.9 – 1.21.11**. Quantum replaces the default Minecraft main menu with a fully custom animated dark UI and brings a suite of quality-of-life modules accessible anywhere in-game through a single keybind. It ships with a custom high-quality font, a themeable accent-color system, a drag-and-drop HUD editor, and a pixel-perfect crosshair designer. > Internally the project is still named `zenithclient` (package, class names, and config folder), but everything you see in-game is branded **Quantum Client**. ## Features ### Main Menu - Fully custom animated main menu that replaces the vanilla panorama. - Interactive parallax **starfield background** that reacts to your cursor, with a theme-tinted glow. - Animated **"QUANTUM" wordmark**, smooth frame-rate-independent transitions, and a decorative orbit/altitude widget that tracks the hovered menu item. - Smooth hover slides and color cross-fades on every menu row. - The interactive background carries over to the vanilla menu screens too (world select, options, multiplayer), replacing their panorama. ### Themes - 16 built-in accent themes: Lava, Arctic, Jade, Neon, Gold, Mint, Void, Ember, Frost, Rose, Ocean, Sunset, Matrix, Cobalt, Sakura, and Ash. - Every HUD element, menu accent, and toggle recolors to the active theme instantly. ### In-Game Overlay (toggle with **Right Shift**) A draggable settings panel opens over the game, main menu, or any screen. Right-click a module to open its settings sub-panel. **Movement** - **AutoSprint** - sprints automatically; options for omni-directional sprint and sprinting in water. **Visual** - **Fullbright** - removes all darkness (works in every biome and dimension) with an adjustable brightness level and optional night-vision boost. - **Zoom** - hold a key to smoothly zoom in like a spyglass. Configurable magnification, smooth easing, scroll-to-adjust, and a **rebindable zoom key**. - **Crosshair** - draw your own **15×15 crosshair** in a built-in pixel editor. Choose theme-accent color, or leave it off for the true vanilla color-inversion look that adapts to whatever's behind it. Adjustable pixel scale. - **Time Changer** - override the visual time of day with a slider across the full Minecraft day (client-side only, doesn't touch the server). - **Particles** - a themed drifting particle overlay shown behind the settings screen, with density, speed, and theme-color options. - **Custom Font** - toggle the Quantum font on/off globally, with a text-shadow option. **HUD** - **Coordinates** - X Y Z position, with optional facing direction, biome name, background, scale, and screen position. - **FPS Display** - live frames-per-second counter, color-coded by performance, with an optional ms readout. - **Armor HUD** - equipped armor next to the hotbar with durability, theme-colored borders, and a low-durability warning threshold. - **Ping Display** - current server ping in milliseconds, color-coded by latency. - **Keystrokes** - live WASD / mouse / space key display with adjustable opacity and scale. ### HUD Editor - A dedicated drag-and-drop editor to freely reposition every enabled HUD element. - Elements that share a default corner auto-stack so they never overlap. - Double-click to reset an element, or reset everything at once. A grey safe-zone border shows the screen bounds. ### Settings & Config - Every module state and setting saves automatically to config files under `config/zenithclient/`. - Per-module settings panels with animated toggles, sliders, dropdowns, keybind capture, and buttons. - Accessible from anywhere - main menu, singleplayer, or multiplayer - via Right Shift. ## Installation 1.
