I hav made a state machine in Animation State Machine but don’t know how to set the condition to next state

The state machine is inside a animation tree node, so I need to retrieve the state machine first?

Any ideas?

Thanks

Assuming AnimationNodeStateMachine is assigned as a root of animation tree:

# Retrieve state machine controller
var playback = $animation_tree.get("parameters/playback")

# Make sure to `Start` a state machine before any transition can occur
playback.start('rest')

# ... code to change state here ...

if walking:
    # Transition to a new state according to defined transition graph
    playback.travel('walk')

if jumping:
    playback.travel('jump')

Animation state machine transition graph

You can stop the animation state machine simply with:

playback.stop()

See the docs for additional info.
