I LOVE Tween, I love DOTween even more! But having to wait for a recompilation every time you tweak a single value on some animation it's frustrating! Even more complicated is properly have to visualize the entire animation on your head and having to wait until you reach your animation to see what you have done! That's why I created the Animation Sequencer, it is (cloned) HEAVILY INSPIRED from Space Ape amazing Creative Engineering: Balancing & Juicing with Animations presentation.

This is still in heavy development, please use it carefully

• Allow you to create a complex sequence of Tweens/Actions and play on Editor Mode!
• User Friendly interface with a lot of customization
• Easy to extend with project specific actions
• Chain sequences and control entire animated windows with a single interface
• Searchable actions allowing fast interactions and updates
• Can be used for any type of Objects, UI or anything you want!

• Tween Target
  • DOAnchoredPosition
  • DOMove
  • DOScale
  • DORotate
  • DOFade (Canvas Group)
  • DOFade (Graphic)
  • DOPath
  • DOShake (Position/Rotation/Scale)
  • DOPunch (Position/Rotation/Scale)
  • DOText (TextMeshPro Support)
  • DOFill
• Play Particle System
• Play Animation Sequencer

• Animation Sequencer rely on DOTween for now, so it a requirement that you have DOTween on your project with properly created asmdef for it (Created by the DOTween setup panel)
• Add the Animation Sequencer to any GameObject and start your animation!
• Using the + button under the Animation Steps you can add a new step
• Select Tween Target
• Use the Add Actions to add specific tweens to your target
• Press play on the Preview bar to view it on Editor Time.
• To play it by code, just call use animationSequencer.Play();
