AnimatorTransitionCopier is a simple tool to copy paste animation transitions in Animator editor.

It helps you to depart from suffering when you have to change animation states in a huge state machine, such as from clip to blend tree.

Features

  • It holds the order of the transitions in state as well.
• Two ways to copy:
  1. Selected transitions
  2. Ingoing/Outgoing transitions of selected state
• It supports undo/redo as well.
• It supports AnyState, EntryState, and ExitState.
• It supports transitions between StateMachine and State. (yet)

Issues & Warnings

Can it copy transitions between state machine and state??

NO, IT CAN'T.

Although I've tried to implement this feature, it seems impossible to get the outgoing transitions from AnimatorStateMachine. If someone can teach me how to get them, I'll make it.

Pasting AnyState and EntryState seems broken?

NO, IT WORKS

It's kind of a Unity bug that the editor doesn't refresh immediately when you paste the transitions of entry or any state in non-first state machine.

But it actually works, just a UI bug.

Environment

Unity 2019.4.17f1 LTS
