Transform

Description

The position / rotation / scale of an Entity. Every mutating setter flips _changed and calls parent.MarkDirty(), so changing a transform automatically queues the entity for a GPU re-upload. Rotation is stored as Euler degrees; GetQuaternion() converts on demand.

API summary

Member	Kind	Summary
`SetWorldPosition(Vector3D)`	public	Set absolute position.
`MoveToPosition(Vector3D)`	public	Move to a position and drag children along.
`SetLocalPosition(Vector3D)` / `MoveLocalPosition(Vector3D)`	public	Offset by a delta (the `Move*` variant also offsets children).
`SetWorldScale` / `SetLocalScale(Vector3D)`	public	Set scale.
`SetRotationFromVector3(Vector3D)`	public	Set Euler-degree rotation.
`GetQuaternion()`	public	Euler degrees → `Quaternion`.
`GetEntityPosition()` / `GetEntityRotation()` / `GetScale()`	public	Accessors.

Fields & Properties

[@Serializable] public Vector3D<float> position = new(0, 0, 0);
[@Serializable] public Vector3D<float> rotation = new(0, 0, 0);   // Euler degrees
[@Serializable] public Vector3D<float> scale    = new(1, 1, 1);

[NonSerializable] internal Entity parent;
[@Serializable]   internal bool _changed = false;

Methods

Position

SetWorldPosition overwrites; SetLocalPosition / MoveLocalPosition add a delta. MoveLocalPosition recurses into children so they follow the parent.

Scale / Rotation

SetLocalScale / SetWorldScale set scale directly. Rotation is set via SetRotationFromVector3 (degrees) and read back as a quaternion via GetQuaternion().

Notes / gotchas

SetRotationFromQuaternion(q) currently only calls MarkDirty() — it does not store the quaternion, so it has no visible effect yet.
MoveToPosition computes its child delta after overwriting position, so the delta is always zero and children don’t actually move. Use MoveLocalPosition if you need children to follow.
