This plugin exposes the WaterType form to Papyrus. WaterType has two methods to get and set the dangerous flag:
bool Function GetIsDangerous() native
Function SetIsDangerous(bool dangerous) native
The dangerous flag does nothing by itself is used by the IsInDangerousWater condition function.
This function returns TRUE whenever an actor sets foot in dangerous water, even when not swimming.
The related condition function IsSwimming only detects actors who are swimming in water. This small distinction opens up new game play possibilities.
Although the flag can be set in the Creation Kit, this introduces incompatibilities with every single plugin that also modifies waters (for instance, Realistic Water Two SE).
The SetIsDangerous method allows a plugin to be completely compatible by setting the flag by script instead.
The script must run every time a game is loaded because changes to the WaterType forms are not persisted in the save file.
This plugin only works with SKSE64 for Skyrim Special Edition.
