TransformSceneHandle

描述

场景中对象的位置、旋转和缩放。

TransformSceneHandle 是 TransformAccess 上的安全句柄。用于创建此句柄的 Animator 负责管理此句柄的有效性。

public struct TransformSceneHandleJob : IAnimationJob

    {
        // Set the new local position.
        handle.SetLocalPosition(stream, position);

        // Set the new local rotation (converted from euler).
        handle.SetLocalRotation(stream, Quaternion.Euler(rotation));

        // Set the new local scale.
        handle.SetLocalScale(stream, scale);
