Can Curve Spline be used for an in game level editor.

[_Aka_]

Edit** If going the coding wrote, how can i get objects to curve towards the spline.

I assume that this question means: How to make an object, which position you specify,  be deformed following a spline. Correct me if I am wrong.
The mesh deformation is done via the Deform Mesh module. That volume needs a Spots input, that defines the transform of the deformed mesh. The issue is that the Volume Spots does not implement placement rules that you want. So you have multiple choices:

1. Modify the Volume Spots module (class: BuildVolumeSpots) to make it implement your logic. Not the easiest one.
   
2. Make a new module that generates spots using your own logic. A wizard will help you create a module's skeleton at Project's window→Create→Curvy→CG Module. Not that complicated, but not that simple. You will most probably need to take a look on a simple spots generating module (such as Spots, class: InputSpots).
   
3. Make a script, that is not a module, that will populate an existing Spots module (class: InputSpots). This module is basically a list of spots. This is the simplest solution.
   

FYI: the method that does the mesh deformation is DeformMesh.DeformMeshes. It is a public static method. This means that you can use in whatever code you want. I don't believe you will have to, but I am letting you know just in case.

Thanks for taking the time to help out.
