FLX Tools — Procedural Animation Modifiers for Godot 4

FLX Tools adds five procedural animation effects to Godot 4 as native nodes. Add a node under any Node2D (or Sprite2D) and it animates its parent — no scripting required.

The five effects

• FlxWiggle — organic procedural noise on position, scale and opacity.
• FlxStutter — wiggle on a low-FPS clock for a stop-motion / glitch feel.
• FlxSquashStretch — cartoon squash & stretch, continuous or on-impact pulse.
• FlxOvershoot — inertial, After-Effects-style bounce when motion stops.
• FlxEcho — a motion trail of fading ghost copies.

Why FLX Tools

• Native performance — compiled, not GDScript.
• Zero-config — add the node, press play. Live preview in the editor.
• Frame-rate independent — identical at 30, 60 or 240 FPS; no drift over time.
• Deterministic when you want it — a seed locks reproducible motion for trailers, tests, or syncing nodes.
• Truly cross-platform — Windows, macOS, Linux, Android, iOS and Web.
• GDScript and C# — works in standard and Godot .NET (Mono) projects.

What's included

• The flx_tools library with prebuilt binaries for every platform.
• A ready-to-run demo project showcasing all five effects.
• Full documentation.
