Functional/FuncTranslate.cs

A component that moves an entity toward a target world position. It exposes properties ToTranslate and Speed, updates WorldPosition each fixed update using Vector3.Lerp while in a Moving state, snaps to the target when within 0.1 units, and draws a gizmo arrow to the target when selected in editor.
