# 1. Install and SplineContainer Part of [[Splines]]. Next: [[2. Knots and Tangent Modes]]. ## 1.1 Package Package Manager > Unity Registry > **Splines** (`com.unity.splines`). For Editor **6000.5** the official package page lists **2.9.2** as released (2.9.0 and 2.9.1 also available). Confirm the version in the details pane. Namespace: `UnityEngine.Splines`. ## 1.2 Create a path Typical path (confirm the menu string in 2.9.2 if it has moved): 1. **GameObject > Spline > Spline** (or the equivalent create item in your package; some versions also offer a component-only path: empty GameObject + `Spline Container`). 2. You get a GameObject with a `SplineContainer`. The container can hold **one or more** `Spline` objects. 3. In the Scene view, a spline tool overlay lets you click to place knots. Start with three knots in a gentle curve at world origin, scale 1,1,1. The container's transform is the spline's world origin. `Evaluate` results are usually in **world** or **local** depending on the overload - read the 2.9 signature you call (section 3) and do not assume. ## 1.3 When not to use a spline - Two points and a straight lerp do not need a package. - NavMesh agents already path around geometry; a spline is for *authored* routes (tours, rails, placements), not for "get to the player." - A Timeline-only camera with three key poses may be simpler than a dolly ([[Timeline Basics]]). ## 1.4 Exercise Create a container, three knots, and select the GameObject. In the Inspector you should see at least one spline and knot data. Leave Play Mode off until you evaluate in part 3. ## Sources - Splines 2.9.2 for 6000.5: https://docs.unity.com/en-us/engine/6000.5/manual/packages-list/packages-all/pack-safe/com-unity-splines
