Update Tweencel v2.2
This version introduces smoother animation tools, stability fixes, and greater support for linked cels. Please uninstall the previous version before installing this update.
Changes:
- [Fix] Prevent “attempt to index a nil value (local 'end_frame')” error when tweening
- [Fix] Resolve “tried to access deleted 'ImageObject'” error when updating tweens on linked cels
- [Fix] Resolve “tried to access a deleted 'Cel'” error during color tweening
- [Improvement] Tweening now fully supports linked cels, no need to unlink them
- [Improvement] Size tweening: scaling now anchors from the image center. No need to toggle position
- [Improvement] Reorganized dialog layout for a cleaner, more compact interface
- [Feature] Added Minimize and Advanced toggles to simplify the UI
- [Feature] Added Motion Path Options when tweening position
- [Feature] Added Squash & Stretch Support for size tweening
- [Feature] Added Out-In easing option for more expressive timing
🪄 Motion Path Options
Choose how your sprite moves between frames, beyond just straight lines:
- Straight - Basic linear interpolation.
- Arc - Adds a natural jump arc or bounce feel.
- Wave - Wavy sinusoidal movement across the path.
- Triangle (Zigzag) - Sharp zigzag patterns using triangle waves.
- Shake - Random jitter, great for camera shake or chaotic effects.
🏀 Squash & Stretch Support
Add cartoony energy and elasticity to your tweens. Enable squash and stretch to exaggerate motion dynamically, automatically adapting to the direction of movement:
- Horizontal motion - wider and flatter stretch
- Vertical motion - taller and thinner squash
This adds personality and physics-inspired realism to your sprite animations.
