How can I add affordances?

[Dr. Z]

I want to create a floor you can build on mud to make it useable, but there isn't an affordance unique to mud, does anyone know how and where to add one?

[Rikiki]

Adding an affordance would probably require to modify the core code. So this is just not possible I think.

I don't know if it works for floors (works for building at least) but you could just write your own placement_restricter like that:

Code Select Expand


public class PlacementRestricter_OnMud : PlacementRestricter
{
   if (Find.TerrainGrid.TerrainAt(loc).defName == "Mud")
   {
      return (true);
   }
   else
   {
      return (false);
   }
}

Unfortunately I'm a modding newbie, so I was hoping that it would be done with adding a line somewhere in a dll :/

[Rikiki]

  euh... this a piece of code for a dll.

You maybe mean "in an XML file" ?

[Dr. Z]

No, I meant dll, your original post just sounded like I had to write one on my own instead of just adding something (for my understanding, a dll is like a huge wall of hieroglyphics at the moment).

This should work:
<affordances>
         <li>Any</li>
</affordances>

These are the terrain affordances currently in the game: (Thanks to ILSpy)
Any
Light
Heavy
GrowSoil
Diggable
SmoothHard
SmoothableStone

That's actually a good idea for now, I will do this till I can realise Rikikis suggestion so you can build them only on mud. Thanks for your answeres

@ Rikiki

Where would I have to add your code?

[Rikiki]

Mmh, to get started, I suggest you to follow the instructions of the Dark-matter generator tutorial.

Then you have to create a class that expands Placement_Restricter (get the Deepdriller mod for a complete/working example).

And finally, don't forget to set your custom placement restricter within your xml floor def:

Code Select Expand


<placementRestricters>
   <li>Deepdriller.PlacementRestricter_Deepdriller</li>
</placementRestricters>


Ask away if you are lost at some step
