AnimationLayerMixerPlayable.SetLayerMaskFromAvatarMask

切换到手册
public void SetLayerMaskFromAvatarMask (uint layerIndex, AvatarMask mask);

参数

layerIndex 层索引。
mask 用于创建新 LayerMask 的 AvatarMask。

描述

设置当前层的遮罩。

此函数从指定 AvatarMask 生成一个层遮罩，并将其应用于指定的层索引。如果您更改 AvatarMask，则需要再次调用此函数来更新层遮罩。

public class LayerMixerPlayable : MonoBehaviour

    public AnimationClip clip1;
    public AnimationClip clip2;

        // Create mixer playable
        m_Mixer = AnimationLayerMixerPlayable.Create(m_Graph, 2);

        // Create two layers, second is setup to override the first layer and affect only left shoulder and childs
        m_Mixer.ConnectInput(0, clipPlayable1, 0, 1.0f);
        m_Mixer.ConnectInput(1, clipPlayable2, 0, mixLevel);

        m_Mixer.SetLayerMaskFromAvatarMask(1, mask);

        m_Graph.Play();
    }

    public void Update()
    {
        m_Mixer.SetInputWeight(1, mixLevel);
    }

    public void OnDestroy()
    {
        m_Graph.Destroy();
    }
}
