説明

PlayableBehaviour is the base class from which every custom playable script derives.

A PlayableBehaviour can be used to add user-defined behaviour to a PlayableGraph.

A PlayableBehaviour must be part of a branch of a PlayableGraph that is connected to an output to be active.

In the following example, two AnimationClip are controlled by two AnimationClipPlayable, which are blended by a AnimationMixerPlayable. A custom BlenderPlayableBehaviour is modifying the inputs weigth of the AnimationMixerPlayable every frame.

using UnityEngine;
using UnityEngine.Animations;
using UnityEngine.Playables;

public class BlenderPlayableBehaviour : PlayableBehaviour { public AnimationMixerPlayable mixerPlayable;

public override void PrepareFrame(Playable playable, FrameData info) { float blend = Mathf.PingPong((float)playable.GetTime(), 1.0f);

mixerPlayable.SetInputWeight(0, blend); mixerPlayable.SetInputWeight(1, 1.0f - blend);

base.PrepareFrame(playable, info); } }

public class PlayableBehaviourSample : MonoBehaviour { PlayableGraph m_Graph; public AnimationClip clipA; public AnimationClip clipB;

// Use this for initialization void Start() { // Create the PlayableGraph. m_Graph = PlayableGraph.Create();

// Add an AnimationPlayableOutput to the graph. var animOutput = AnimationPlayableOutput.Create(m_Graph, "AnimationOutput", GetComponent<Animator>());

// Add an AnimationMixerPlayable to the graph. var mixerPlayable = AnimationMixerPlayable.Create(m_Graph, 2, false);

// Add two AnimationClipPlayable to the graph. var clipPlayableA = AnimationClipPlayable.Create(m_Graph, clipA); var clipPlayableB = AnimationClipPlayable.Create(m_Graph, clipB);

// Add a custom PlayableBehaviour to the graph. // This behavior will change the weights of the mixer dynamically. var blenderPlayable = ScriptPlayable<BlenderPlayableBehaviour>.Create(m_Graph, 1); blenderPlayable.GetBehaviour().mixerPlayable = mixerPlayable;

// Create the topology, connect the AnimationClipPlayable to the // AnimationMixerPlayable. Also add the BlenderPlayableBehaviour. m_Graph.Connect(clipPlayableA, 0, mixerPlayable, 0); m_Graph.Connect(clipPlayableB, 0, mixerPlayable, 1); m_Graph.Connect(mixerPlayable, 0, blenderPlayable, 0);

// Use the ScriptPlayable as the source for the AnimationPlayableOutput. // Since it's a ScriptPlayable, also set the source input port to make the // passthrough to the AnimationMixerPlayable. animOutput.SetSourcePlayable(blenderPlayable); animOutput.SetSourceInputPort(0);

// Play the graph. m_Graph.Play(); }

private void OnDestroy() { // Destroy the graph once done with it. m_Graph.Destroy(); } }
