Importing

At all times you must ensure your project is free of any console errors. Unresolved code errors will prevent this asset’s scripts from compiling. This results in all of its functionality remaining unavailable.

Under no circumstances must your project contain a script, without namespace, called “Spline” or “Editor”. This wreaks havoc to no fault of this asset.

Project Setup

Ensure you have the Splines package installed, version 2.8.1 or newer is required.

If the asset is imported without this package installed, demo scene content may have been broken. Reimport the demo scene from the asset store if this is the case (after installing the package).

Please do not attempt to import this asset into a Unity 2021 project. It will auto-install the Collections v2.5.1 package, which isn’t compatible with this version. You’d have to manually downgrade it again to fix your project.

    Scene Setup

    Familiarity with Unity’s spline tool is assumed here, and its workings are not covered here.

    You’ll need to know how to:

    • Create a Spline object
    • Use its editor tool
    • Insert new knots

    Creating a spawner

    Adding it to a Spline

    Once you have a Spline set up in your scene adding a Spline Spawner to it can be achieved through the Spline Container’s context menu:

    With the Spline Spawner component added, assign a prefab to spawn, or drag & drop one in.

    From any GameObject

    From any Transform component’s context menu you can access the “Spawn on spline” option.

    You will be asked if you’d like to create a new Spline for the created spawner. If not, you can assign an existing spline later on.

    Create a brand new one

    Go to GameObject→Spline→Spawner to create a new GameObject with a blank spawner component.
