<brief_description>
|
|
A transition within an [AnimationTree] connecting two [AnimationNode]s.
|
|
</brief_description>
|
|
<description>
|
|
Simple state machine for cases which don't require a more advanced [AnimationNodeStateMachine]. Animations can be connected to the inputs and transition times can be specified.
|
|
After setting the request and changing the animation playback, the transition node automatically clears the request on the next process frame by setting its [code]transition_request[/code] value to empty.
|
|
[b]Note:[/b] When using a cross-fade, [code]current_state[/code] and [code]current_index[/code] change to the next state immediately after the cross-fade begins.

Enables or disables auto-advance for the given [param input] index. If enabled, state changes to the next input after playing the animation once. If enabled for the last input state, it loops to the first.

<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 transition to the self state. When the reset option is enabled in input, the animation is restarted. If [code]false[/code], nothing happens on the transition to the self state.
|

<member name="input_count" type="int" setter="set_input_count" getter="get_input_count" default="0">
|
|
The number of enabled input ports for this animation node.

|
|
<member name="xfade_curve" type="Curve" setter="set_xfade_curve" getter="get_xfade_curve">
|
|
Determines how cross-fading between animations is eased. If empty, the transition will be linear.
|
|
</member>
|
|
<member name="xfade_time" type="float" setter="set_xfade_time" getter="get_xfade_time" default="0.0">
|
|
Cross-fading time (in seconds) between each animation connected to the inputs.
|
|
[b]Note:[/b] [AnimationNodeTransition] transitions the current state immediately after the start of the fading. The precise remaining time can only be inferred from the main animation. When [AnimationNodeOutput] is considered as the most upstream, so the [member xfade_time] is not scaled depending on the downstream delta. See also [member AnimationNodeOneShot.fadeout_time].
