|
|
A state machine with multiple [AnimationRootNode]s, used by [AnimationTree].
|
|
</brief_description>
|
|
<description>
|
|
Contains multiple [AnimationRootNode]s representing animation states, connected in a graph. Node transitions can be configured to happen automatically or via code, using a shortest-path algorithm. Retrieve the [AnimationNodeStateMachinePlayback] object from the [AnimationTree] node to control it programmatically.
|
|
[b]Example:[/b]
|
|
[codeblocks]
|
|
[gdscript]
|
|
var state_machine = $AnimationTree.get("parameters/playback")
|
|
state_machine.travel("some_state")
|
|
[/gdscript]
|
|
[csharp]
|
|
var stateMachine = GetNode<AnimationTree>("AnimationTree").Get("parameters/playback") as AnimationNodeStateMachinePlayback;
|
|
stateMachine.Travel("some_state");
|
|
[/csharp]
|
|
[/codeblocks]

<member name="allow_transition_to_self" type="bool" setter="set_allow_transition_to_self" getter="is_allow_transition_to_self" default="false">
|
|
If [code]true[/code], allows teleport to the self state with [method AnimationNodeStateMachinePlayback.travel]. When the reset option is enabled in [method AnimationNodeStateMachinePlayback.travel], the animation is restarted. If [code]false[/code], nothing happens on the teleportation to the self state.

</member>
|
|
<member name="reset_ends" type="bool" setter="set_reset_ends" getter="are_ends_reset" default="false">
|
|
If [code]true[/code], treat the cross-fade to the start and end nodes as a blend with the RESET animation.
|
|
In most cases, when additional cross-fades are performed in the parent [AnimationNode] of the state machine, setting this property to [code]false[/code] and matching the cross-fade time of the parent [AnimationNode] and the state machine's start node and end node gives good results.

Seeking to the beginning is treated as playing from the start state. Transition to the end state is treated as exiting the state machine.

<constant name="STATE_MACHINE_TYPE_NESTED" value="1" enum="StateMachineType">

Seeking to the beginning is treated as seeking to the beginning of the animation in the current state. Transition to the end state, or the absence of transitions in each state, is treated as exiting the state machine.

This is a grouped state machine that can be controlled from a parent state machine. It does not work on standalone. There must be a state machine with [member state_machine_type] of [constant STATE_MACHINE_TYPE_ROOT] or [constant STATE_MACHINE_TYPE_NESTED] in the parent or ancestor.
