How do I travel to a state when a animation ends?

How do I use animation player states and transitions to travel to a state when the animation is over?

[derkork]

When an animation player state is activated it will automatically start the configured animation in the linked animation player. The animation player has a signal animation_finished which you can listen to and then send an event to the state chart. Then a transition inside the animation player state can listen to this and transition elsewhere.

In this example I have two states one plays an animation RotateLeft and the other one plays an animation RotateRight. Both states have a transition to the other state which listens on the animation_player_finished event. I also have connected the animation_finished signal of the animation player to a function which will send the animation_player_finished event to the state chart:

Now when the scene starts this happens:

• the "RotateLeft" state will be entered. It will play the "RotateLeft" animation.
• once the animation finishes playing, the animation player emits the `animation_finished´signal.
• the _on_animation_player_animation_finished method will be called and sends an animation_player_finished event to the state chart.
• the "Switch To Right" transition is triggered and activates the "RotateRight" state.
• The "RotateRight" state is entered and plays the "RotateRight" animation.
• once the animation finishes playing, the animation player emits the `animation_finished´signal.
• the _on_animation_player_animation_finished method will be called and sends an animation_player_finished event to the state chart.
• the "Switch toLeft" transition is triggered and activates the "RotateLeft" state.
• and then everything repeats forever.

Here is the scene for you to try out: test.tscn.zip

I hope this helps.

I would like to add to this, for those of you who do not use Animation Player States but would like similar functionality.

I've had good luck so far with adding a Call Method track on the last frame of an animation I want to transition to another state by invoking the send_event function with a StringName argument containing whatever value would cause the transition from the current state.

Hope that's helpful to someone!
