UITweenKit

UI Tween Kit brings smooth, expressive animation to Unity UI Toolkit — with a concise C# API and a full visual keyframe editor. ONE LINE TO ANIMATE myElement.TweenFade(1f, 0.3f); Add "using UITweenKit;" and you're done. No managers, no prefabs, nothing to configure. CHAINABLE API Every tween chains in any order: button.TweenScale(1.2f, 0.2f).SetEase(Ease.OutBack).SetDelay(0.1f).OnComplete(...); Animate opacity, position, scale, rotation, size, colors, margins, borders — or anything at all through a getter/setter, including your own values. SEQUENCES Append, Join, Insert, intervals and callbacks - build entrance choreographies that read like sentences. JUICE, READY TO USE Shake, punch, pop, slide in/out, pulse, flash, typewriter text, path movement along curves - one call each. VISUAL CLIP EDITOR Build animations without code. Create a clip, see your UXML rendered live inside the editor window with a full element tree, and animate by hand: - Click any element to select it and add tracks — no typing names - Move, Scale and Rotate tools (W/E/R) — drag elements and keys are recorded at the playhead - Record panel for position, scale, rotation, opacity and colors, with Unity-style drag-to-scrub fields - Timeline with draggable keys, per-key easing, markers, frame snapping - Play your animation right in the editor, no Play mode needed - Ready-made templates: Fade In, Pop In, Pulse, Slide In - Full undo support PLAY CLIPS WITHOUT CODE Drop a UITweenPlayer component next to your UIDocument, assign a clip, and wire onStarted, onCompleted and onMarker events in the inspector like you would with Buttons. LIVE PREVIEW Drive a scene UIDocument straight from the timeline — scrub and watch your real UI move, with every style restored when you're done. PERFORMANCE Tweens are pooled and reused for a light GC footprint on mobile, clean themselves up automatically, and smooth out frame-time spikes so animations never jump. INCLUDED - Complete runtime API and visual editor - 31 easing curves plus AnimationCurve support - Six sample scenes including a full game menu showcase - README and full documentation Unity 2022.3+ (Unity 6 ready). Built-in, URP and HDRP. Support: verycoolgamestudio@gmail.com
