Through several experiments, I found that the game can handle surface water perfectly fine, complete with changes in elevation, by just having the tile be declared as a water texture. Setting ocean height in my TerrainSampler implementation to a high value showed that easily. By default, the game will check if the height is below an artificially set sea level, if it is that low then set it to sea level, and in TerrainTexturing it will set all values below or at sea level to ocean tiles.

In my implementation I skip the first check and get "water hills", which is useful to know the game can handle "sloped surface water" but frustrating since I cannot find any way to override the texturing process to declare "this is water" and "this is land" manually. The texturing system seems to be intended to allow for separate instances, but is set in the game as "readonly".

What I have:
An 5000x2500 RGB 16-bit custom terrain image
- Red: Height
- Green: Vegetation Density
- Blue: Water Mask

What I Want:
To be able to use this water mask to tell the game to make a tile be water.
To have this work as a mod.

I know that this can work in the game. I could directly change the terrain texturing system to do what I want, but I'm pretty sure I couldn't compile it that into a dfmod, could I?

        blbTerrainSampler = new BLBTerrainSampler(noiseSettings);
        DaggerfallUnity.Instance.TerrainSampler = blbTerrainSampler;
        DaggerfallUnity.Instance.TerrainTexturing = new BLBTerrainTexturing();

Jeoshua wrote: ↑Sat Dec 28, 2019 9:29 pm Well, the inheritance works, I think, but the code to inject it doesn't. I think I understand what it's supposed to do, by swapping the script that the game object points to. Doesn't matter if the code is immutable then, since the GameObject isn't.

When was the last time you tried to run this? I get an error on compile:

Code: Select all

error CS16061: Type `Daggerfall Workshop.DaggerfallUnity' does not contain a definition for `TerrainTexturing' and no extension method `TerrainTexturing' could be found. Are you missing an assembly reference?

And, when checking out Daggerfall.cs, indeed, there is no such entry. The only reference to the terrain texturing system I can find is in StreamingWorld.cs, and that's the readonly member.

Jeoshua wrote: ↑Sat Dec 28, 2019 10:00 pm Well yes and no. I have a Texture2d image in which one channel is height, another is water, and a third is vegetation/wetness. The idea is to use the values from the blue channel to declare "this is a water tile". The way the game works by default there is no way to do this, as water is height based only (or set in locations which is out of scope here), and this is set in the TerrainTexturing class.

I just wanted to limit my effort in replacing the whole class, and by C# semantics it should work, but the stopping point I'm reaching is before that. The idea of replacing the TerrainTexturing class is sound, except DaggerfallUnity.TerrainTexturing does not seem to exist for me. I'm using the latest source code from Git as of the day before Christmas.

DaggerfallUnity.Instance.TerrainTexturing = new BLBTerrainTexturing();
