5.Buoyancy #

The package comes with scripting functionality that allows the water surface height and orientation to be read. This in turn can be used for buoyancy calculations. Familiarity with scripting is assumed in order to understand how to use this. If you’re set on making a buoyancy system, understand that it’s potentially a complex task.

This API primarily provides the necessary functionality for third party/custom buoyancy systems. It does not feature boat controllers or true physics-based buoyancy.

Buoyancy will only work for flat water bodies. Rivers or spheres are technically not possible without some complex scripting magic, this starts to delve into a custom physics system.

The wave height and normal can be read at any world position using this static function:

StylizedWater2.Buoyancy.SampleWaves(Vector3 position, Material waterMat, float waterLevel, float rollStrength, bool dynamicMaterial, out Vector3 normal);

The function has a summary, you can view a description for each parameter in your IDE, as well as any overload functions.

For buoyancy to work, on the material the “UV Source” under the General tab must be set to “World XZ projected” (default)

The returned information is likely far more accurate than the visual representation of the water mesh. It does not return the height/normal of a mesh’s triangles.

If you are using an assembly definition, ensure you add a reference to the sc.stylizedwater2.runtime assembly, otherwise you won’t be able to access the StylizedWater2.Buoyancy class.

Floating Transform

This component makes a GameObject and all of its child objects float on the water. It’s a basic non-physics based buoyancy implementation.

Because the script sets the orientation of the Transform, modifying all axis, it cannot be rotated manually or through other scripts. Instead, set the rotation of the child objects directly. The position (X/Z value) can be changed freely.

Dynamic Water Physics 2

The DWP2 asset is an advanced buoyancy/hydrodynamics system, that includes a ship controller. An integration is included, that allows them to be used together.

To install the integration, see the Third party integrations section. Note: A minimum of version 2.4.2 is required!

By default, the DWP2 water object will use a FlatWaterDataProvider component. Remove this, and add the StylizedWaterDataProvider component. You will have to assign the water material you are using, since this script requires to know what kind of parameters are used for the waves.

For any further details, please refer to the DWP2 manual… (I’m not the author)
