Require explicit painting of water tiles to create water

[_kali]

I have a few ideas for some maps where there is water at different elevations, like mountain lakes. As well, as some below sea-level terrain (like Denmark). However, in generating random maps, currently there is a universal waterline (0 elevation) and water is applied to all terrain below that waterline, even if it is explicitly painted a different terrain (like "mainTerrain").

In the map attached, I created a normal lake in the middle of the map, depth of -5 elevation.

To the bottom left, I created a mountain at 10 elevation, and then placed what should be a lake on top of the mountain (painted with the "water" terrain at 7 elevation). However, only the shoreline terrain is applied, as the depth of the mountain lake does not fall below 0.

In the top right, I created a valley at -5 elevation and painted it with the "mainTerrain" and "dirt" terrains, however it is automatically filled with water since it falls below 0 elevation.

Is there a way to get this map to render properly where there is a mountain lake in the bottom left and a valley with no water in the top right?

The map is rendered propperly ;)

There are several different things you talk about here:

• Terrain Elevation (Sometimes just referred to as elevation, the shape of the ground, see ​http://trac.wildfiregames.com/wiki/Rmgen_Library#AccessingMapDataDirectly)
• Terrain Texture (The texture the ground is painted with, reference as above)
• Water Level (At wich height the water surface will be, see ​http://trac.wildfiregames.com/wiki/Rmgen_Library#EnvironmentHelpers)

Those things might seem to be strongly related at first glance but they not all are e.g. painting a playground blue will not cause the water to raise untill that place is under water.

Additional confusion might be added by the fact "terrains" in the random map generation (RMGen) library references most of the times means a combination of a terrain texture and - possibly - an actor (like a flower) or an entity (like a harvestable tree).

Additionally entities and actors are not really distinguished in RMGen, refering to them most of the times simply as "entities".

To be able to raise the water level to fill the mountain lake but not flood most of the rest of the map requires a water height map - similar to the terrain reliefmap (present in g_Map.height). That would require the engine to support it (that may be the case allready though absolutely untested AFAIK) and all related functionality (like Atlas/generate maps, save/load maps, generate random maps, export random maps, passability checks, placement checks and likely more).

So, no, it's not a planned feature AFAIK.

I hope that helped. I think this ticket can be closed.

Closing this as a wontfix because this is really dependent on multiple water plane, which is a semi-planned feature we don't have right now, and that perhaps should be in ​http://trac.wildfiregames.com/ticket/48.

To answer the ticket question: there is no current way to render properly where there is a mountain lake in the bottom left and a valley with no water in the top right.
