Overview

Package ns implements NoxScript 4 used in OpenNox maps.

NS4 is based on NoxScript 3 but provides a more Go-friendly object-oriented API.

These changes include:

- Most functions became methods on the corresponding object types. - Functions have a more generic signature, using interfaces where appropriate. - Similar methods were renamed, e.g. ObjectOn and WaypointOn is now called Enable for both types. - Type safety was improved. Package defines more names types for enums. - All enum constants were moved to their own sub-packages.

Package is compatible with NS3: methods like AsObj convert NS3 objects into NS4 objects.
