Making an animal stick to a specific type of terrain.

[ItchyFlea]

I've been thinking about adding fish to the coastal terrain generator, but don't know how to restrict them to the water tiles. Anybody know of a way, or willing to create a .dll that does this?

Did the Sand Lizard do this? I forget. Maybe it only spawns on desert but can move anywhere...

You could look on vanillia ++ mod it have a zone that can contain colonist doing jobs only in it.

I've looked into this a while back, I think the only way to do it properly is to write a custom A* pathfinder.
If I recall correctly, in alpha 3 it keeps a bool grid of all the passable tiles. Maybe you can work around creating a whole new pathfinding class if you store a custom passability bool grid somewhere and swap them when needed. Though I have a feeling the new region system in alpha 4 might make this alot harder.

On a sidenote, I did find a neat trick to make animal textures semi transparent. I haven't looked at alpha 4 much yet, but here's some code that works fine in alpha 3:

Code Select Expand

namespace Shai
{
    public class Hulud : Pawn
    {
        static Graphic naked = new Graphic(PawnKindDef.Named("Shai-Hulud").standardBodyGraphicPath, Color.white, MatBases.Transparent);

        public override void DrawAt(Vector3 drawLoc)
        {
            PawnGraphics graphics = drawer.renderer.graphics;

            if (!graphics.Resolved)
                graphics.nakedGraphic = naked;

            this.drawer.renderer.RenderPawnAt(drawLoc);
            this.stances.StanceTrackerDraw();
            this.pather.PatherDraw();
        }
    }
}

Sand Lizards can move anywhere.

You could look on vanillia ++ mod it have a zone that can contain colonist doing jobs only in it.

The Vanilla+ "Stay inside during threats" option only changes the behaviour of AI.JobGiver.WorkRoot.TryGiveTerminalJob(Pawn pawn) so it skips destinations outside of the home region when there are enemies on the map.

There is <baseMaterialType>Transparent</baseMaterialType> thingy in xml, but it dont really change anything much just make stuff abit darker, and transparency on textures still have only 3 levels.
Then again the code thing might be better

Oh, interesting... what do you mean with "only 3 levels" though? With "the code thing", you can just use the full range of the alpha channel in the image.

Well opacity that is above 53% of the layer without visible background( also above 53%) will be a solid color in game.
Opacity of 50-51% is a slight opacity you can see thrugh but only when there is high contrast betwhen texture color and background, soo you could see black dots on the ground thrugh white texture.
And lvl 3 is 49% and below opacity, only the outlines of texture are shown.
Dont know anything about alpha channel except is a good way to save selections

Edit:Well ok im stupid just learned alpha channel stuff and opacity works fine
Thanks btw

Maybe...you could define the sea as its own region somehow? Then keep that fish in that region.

The easiest way I can think of would be to create a ThinkTree for them that uses a special version of the Wander node that only chooses wander destinations in water. Of course, every other behavior would also need to be overridden to choose water-only destinations.
